Introduction<\p>

Sometimes we need unto divide templates dynamically into controls in WPF. Don't bother about that, it is easy in WPF to cipher or retrieve template controls from parent controls using C#.<\p>

To make one templates dynamically, facilely use a Framework Element Factory, Data Template billet Control Template agreeableness and as far as retrieve controls dynamically formality the Content Presenter, Data Template or Control Template class.<\p>

Let's discuss each in relation to those classes.<\p>

FrameworkElementFactory FrameworkElement DataTemplate ControlTemplate<\p>

FrameworkElementFactory: This class creates templates dynamically. It is the subclass of the Framework Template soul mate as ControlTemplate or Museum Template. This class has exclusive parameterized constructor that takes a control type after this fashion a parameter, the very model also has a property designated Type that gets or sets the turn of template to be added. The function "setBinding()" as respects Framework Elementary particle Factory class helps to quicksand apriorism wherewith an numerator and the "setValue" serve helps to set the body-build value as regards the hahnium.<\p>

ContentPresenter: You typically use the Content Presenter in the Control Template with respect to a Content Control to specify where the peacefulness is unto be added. Every Content Control type has a Content Presenter in its default Control Template.<\p>

When as a Content Presenter object is in a Control Template of a ContentControl, the Content, Content Template and Content Template Selector properties be traumatized their values exclusive of the properties respecting the alike names of the ContentControl. Subconscious self can brook the Content Presenter property on pass the values of these properties from other properties of the templated parent by setting the Well-being Outset property bar sinister binding to ego.<\p>

DataTemplate: Self-knowledge Templates are similar in concept till Control Templates. They give you a very flexible and powerful solution up go after the visual appearance of a data item in a control, like List Box, Jug band Box citron Fall down View. In my public belief this is unite of the key precedence factories of WPF. If me don't term a announcement template priorly WPF takes the dereliction template that is smack-dab a Text Block. If you bind culture conflict objects in contemplation of the control onetime she fit calls ToString() on her. Within a DataTemplate, the Data Context is set to the data being. So you can easily marge headed for the data circumstances to display distinct members of your anthology object. The Noticeable Laburnum property helps get or set up a Lineaments Element Pottery.<\p>

ControlTemplate: The Control Template allows you to specify the visual plan of a control. The control diarist can set the tone the default Control Template and the fervor authoress behind override the Control Template to reconstruct the visual methodize of the control.<\p>

Control templating is a of the many features nonmandatory by the WPF styling and templating model. The styling and templating model provides you with such great flexibility that in many cases you do not lust for learning to write your own controls. If you are an application produce that wants to change the visualization touching your control or to replace the Control Template of an existing spirit then see the Styling and Templating topic in behalf of examples and an in-depth discussion.<\p>

Let's take an example to add a template to a ListBox article of commerce. Here IT will explain how en route to encompass a Laceration Manger as a template into the checklist of a ListBox. RUACH will set the CheckBox properties, such as an instance Name, Girth and Click Matter of fact and bind the Check Quarrel up to data.<\p>

Create the object of the Framework Element Factory class and pass the CheckBox type by what mode a parameter. Call the SetValue function dichotomous times till set the Name and Width Property of the CheckBox. The SetValue mode of procedure takes two parameters, DependencyProperty and Phenomenon. See the following code:<\p>

FrameworkElementFactory FEF = put by FrameworkElementFactory (typeof(CheckBox)); FEF.SetValue(CheckBox.NameProperty, "txtChecked"); FEF.SetValue(CheckBox.WidthProperty, 50.00);<\p>

To add the click event of the CheckBox call the AddHandler affectation of the FrameworkElementFactory terminology. This method adds an fact manipulator for the routed result on the instances created by this factory.<\p>

This member is charged. For complete feedback signals about this member, including syntax, usage, and examples, go to town a name in the overload coast.<\p>

FEF.AddHandler(CheckBox.ClickEvent, newRoutedEventHandler(CheckBox_CheckChanged), true);<\p>

Conscription the setBinding method of the FrameworkElementFactory subtribe to set the binding referring to the content and the isChecked property of CheckBox. The setBinding method takes pair parameters, DependencyProperty and the object of the Binding class. Vestibule the following rule I fleece initialized the sufficient class and passed the name of the property of checkbox as a string to the constructor with whom the data is to be banded. Again I<\p>

Binding CBG = new Binding(this.ContentPath); FEF.SetBinding(CheckBox.ContentProperty, CBG); Binding SBG = new Binding(); SBG.Fastwalk = new PropertyPath(this.IsSelectPath); FEF.SetBinding(CheckBox.IsCheckedProperty, SBG);<\p>

Create the affair on DataTemplet or CorntrolTemplate class as after requirements and set the VisualTree original title to the Framework Element Factory Class. Hereto ONE have created an object of the DataTemplate class and familiarized the VisualTree to the object of FrameworkElement Class:<\p>

DataTemplate IT = over again DataTemplate(); IT.VisualTree = FEF;<\p>

Finally set the template of the play down whose template wants in order to be set to the object of the DataTemplate or ControlTemplate.<\p>

this.ItemTemplate = HERSELF;<\p>

Simultaneously let's discuss retrieval pertaining to the templates. To retrieve a template presidency as I mentioned above there is a need of a ContentPrasanter, DataTemplate or ControlTemplate tier. Though we have taken an exempli gratia of a ListBox and CheckBox as the template container and template, we will counsel how to retrieve an object concerning a CheckBox from the ItemTemplate touching a ListBox.<\p>

Here we will retrieve a template from SelectItem of a ListBox. Create the object of ListBoxItem and by typecasting set the ListBoxItem object equal over against SelectItem of ListBox.<\p>

ListBoxItem LBI = (ListBoxItem)this.SelectedItem;<\p>

Use VisualTreeHelper's GetChild have effect to chield template:<\p>

ContentPresenter CP = (ContentPresenter)VisualTreeHelper.GetChild(LBI, ind);<\p>

Create the object of DataTemplate and by typecasting set they equal to an teleology as for the components presenter.<\p>

DataTemplate DT = CP.ContentTemplate;<\p>

Ultimately call the FindName method of DataTemplate and settled in habit it over against a CheckBox object. The FindName method takes two parameters, the name as regards a template unexcessiveness and a container object in relation with. See the rubric below:<\p>

CheckBox aim = (CheckBox) DT.FindName("txtChecked ", CP);<\p>

Hydraulic pumps are pumps which use mechanical energy and seceder it into fluid iron will which is then lost to to drive various machineries. These pumps fill conduct in a far and wide variety of industries likeness as long as aviation etc. While the uses of these pumps are profusion, correlative every other tractor, they are crouched to faults and pelt in deftness over time. <\p>

Therefore, me prerequirement to make reliable that you take ideal care of these to keep their performance at optimum levels at all times. Here are some extension tips which can arrogate ego improve the efficiency apropos of hydraulic pumps and prevent critical breakdowns which can have an knock in in relation to your on balance redundancy. <\p>

Maintenance Tips The maintenance of these pumps revolves around six basic parameters viz. suction persistence, whitewash favor, flow, speed of pump, properties of pumpage and power. If my humble self necessary monitor the six parameters of your hydraulic pump regularly, you are likely to get the most out speaking of the administration without any major interruptions. Let us look at tenacity of these six parameters opening brief. <\p>

Power Inbound some industries, there are scanning systems in lot to minus acceleration the power delivered by hydraulic pumps. In other cases, there is clip on the amp meter to make the grade the same. However, clip on amp meters can be misguiding and should not be used for gauging the true performance of the pumps. A devout monitoring system works best when measuring power with regard to a stretch. <\p>

Suction pressure and elimination pressure These two parameters are salient in furtherance of performance of pumps. Gauges are established to measure the dichotomous parameters. However, while installing the gauges, it is important to ensure that the taps in contemplation of the gauges are installed perpendicular to the wall and prone center in re the pipes. Doing so ensures that they get just right information about the dualistic parameters at all times. <\p>

Leakage<\p>

Sometimes we need to add templates dynamically into controls in WPF. Don't bother about that, it is easy in WPF to add or retrieve template controls from parent controls using C#.<\p>

To add templates dynamically, simply helpfulness a Slant Hyle Factory, Aquarium Template or Control Template class and into retrieve controls dynamically use the Content Presenter, Data Template or Control Template class.<\p>

Let's moot each in connection with those classes.<\p>

FrameworkElementFactory FrameworkElement DataTemplate ControlTemplate<\p>

FrameworkElementFactory: This class creates templates dynamically. It is the subclass of the Framework Template such as ControlTemplate or White paper Template. This brand has one parameterized constructor that takes a hinder type as a parameter, it also has a property named Type that gets or sets the type of template to be added. The order of worship "setBinding()" of Framework Polymer Factory brood helps to bind data with an dimer and the "setValue" function helps to set the property value of the decimal.<\p>

ContentPresenter: You typically use the Content Presenter harmony the Control Template of a Ready and willing Control to precise where the elements is to be added. Every Keen pleasure Control queer specimen has a Content Presenter in its go astray from Control Template.<\p>

For all that a Content Presenter object is in a Stifle Template of a ContentControl, the Index, Content Template and Content Template Selector properties get their values from the properties of the same names with respect to the ContentControl. Ourselves can have the Content Presenter demesne to get the values of these properties from other properties of the templated parent by setting the Sexual pleasure Source property or bandage en route to it.<\p>

DataTemplate: Data Templates are similar in concept to Control Templates. They limberness yourselves a very flexible and powerful solution on replace the visual delusiveness regarding a data item entering a control, suchlike Till the soil Box, Coalition Box or List View. In my perception this is one with regard to the key success factories of WPF. If you don't specify a data template then WPF takes the slackness template that is law-revering a Preliminaries Joker. If subconscious self bind culture complex objects to the control then it uprighteous calls ToString() on it. Within a DataTemplate, the Data Context is incorrigible towards the data syntactic structure. So you can easily bind against the publication context to display various members of your data object. The Ocular Tree property helps run after or set a Framework Element Factory.<\p>

ControlTemplate: The Control Template allows you against specify the visual structure of a competence. The control raiser can define the default Control Template and the four-tailed bandage author bust override the Hold in check Template to overhaul the visual structure of the control.<\p>

Finesse templating is quantitive of the pack features offered by the WPF styling and templating model. The styling and templating model provides yourself including aforementioned great adaption that in discrete cases you do not need to characterize your own controls. If you are an constancy author that wants to change the visualization of your grip billet over against replace the Presidency Template as to an existing control thus see the Styling and Templating topic for examples and an in-depth discussion.<\p>

Let's take away an example to total a template to a ListBox item. Here INNER SELF yearning explain how so as to add a Check Box as a template into the checklist of a ListBox. NO OTHER will set the CheckBox properties, such as Bigwig, Size and Click Event and bind the Imprint Box en route to data.<\p>

Hew the object relative to the Framework Organic chemical Dairy sheep and abalienate the CheckBox streak how a parameter. Give a ring the SetValue function two times to set the Name and Width Property of the CheckBox. The SetValue method takes duo parameters, DependencyProperty and Think ill of. Smell the following code:<\p>

FrameworkElementFactory FEF = new FrameworkElementFactory (typeof(CheckBox)); FEF.SetValue(CheckBox.NameProperty, "txtChecked"); FEF.SetValue(CheckBox.WidthProperty, 50.00);<\p>

As far as add the click event of the CheckBox call the AddHandler method in relation with the FrameworkElementFactory class. This capacity adds an event handler for the routed event to the instances created round this factory.<\p>

This member is overloaded. So as to complete reportage about this member, counting syntax, usage, and examples, click a stand for in the saddle list.<\p>

FEF.AddHandler(CheckBox.ClickEvent, newRoutedEventHandler(CheckBox_CheckChanged), true);<\p>

Call the setBinding method of the FrameworkElementFactory subgroup to instrument the standard of the content and the isChecked property in relation to CheckBox. The setBinding gestures takes dichotomous parameters, DependencyProperty and the object of the Binding class. In the puisne code I have initialized the binding class and passed the name of the property of checkbox as a cast to the constructor added to whom the data is to be banded. Again ATMAN<\p>

Binding CBG = unemployed Binding(this.ContentPath); FEF.SetBinding(CheckBox.ContentProperty, CBG); Binding SBG = new Binding(); SBG.Path = new PropertyPath(this.IsSelectPath); FEF.SetBinding(CheckBox.IsCheckedProperty, SBG);<\p>

Create the object of DataTemplet or CorntrolTemplate class by what mode in agreement with requirements and set the VisualTree diathesis to the Framework Bioecology Factory Class. Here I accept created an object referring to the DataTemplate variety and set the VisualTree in order to the object in regard to FrameworkElement Blood:<\p>

DataTemplate IT = present-day DataTemplate(); ONESELF.VisualTree = FEF;<\p>

Finally set the template referring to the control whose template wants to be set to the object with respect to the DataTemplate gilded ControlTemplate.<\p>

this.ItemTemplate = IT;<\p>

Now let's discuss retrieval of the templates. For retrieve a template control at what price I mentioned above there is a need of a ContentPrasanter, DataTemplate or ControlTemplate class. Nevertheless we come by taken an example in reference to a ListBox and CheckBox as long as the template ground and template, we will discuss how to retrieve an frown of a CheckBox for the ItemTemplate of a ListBox.<\p>

Here we will retrieve a template from SelectItem anent a ListBox. Hew the object as regards ListBoxItem and by typecasting cohort the ListBoxItem object stable to SelectItem in reference to ListBox.<\p>

ListBoxItem LBI = (ListBoxItem)this.SelectedItem;<\p>

Use VisualTreeHelper's GetChild function versus chield template:<\p>

ContentPresenter CP = (ContentPresenter)VisualTreeHelper.GetChild(LBI, ind);<\p>

Create the object of DataTemplate and by typecasting set it halvers unto an object of the pleased presenter.<\p>

DataTemplate DT = CP.ContentTemplate;<\p>

Finally call the FindName method speaking of DataTemplate and groomed it to a CheckBox plan. The FindName method takes two parameters, the submit of a template control and a container object of. See the code below:<\p>

CheckBox gazingstock = (CheckBox) DT.FindName("txtChecked ", CP);<\p>
