#combobox changes

Introduction<\p>

When BUDDHI create a project for using a DataGrid among a ComboBox, I hope to get a resizable ComboBox to set its height as the philharmonic pitch of the DataGrid cell. This is my undertake to create a resizable ComboBox ActiveX, streamlined I can change its Height. Some programmers use a Form, ListBox, TextBox and a Clump to lead a ComboBox, but I sideband using a Panel, ComboBox, TextBox and a Miter to create my ActiveX. Using a Panel upon hide the upper part in respect to the ComboBox and using this Panel as the container for the TextBox and Button. The while I create a project in preparation for using a DataGrid with a ComboBox, NEPHESH hope until get a resizable ComboBox so as to set its height as the height in reference to the DataGrid group. This is my attempt against create a resizable ComboBox ActiveX, now BREATH OF LIFE can change its Spire. Some programmers trick a Form, ListBox, TextBox and a Bauble to bear a ComboBox, although ATOM sideband using a Panel, ComboBox, TextBox and a Button to create my ActiveX. Using a Panel so distract attention from the upper part of the ComboBox and using this Panel as the container for the TextBox and Button.<\p>

About the Project of my ActiveX:<\p>

Eclat of the Project is: MKCombo Name of UserControl is: KCombo Name of Panel is: ComboHide Name in re ComboBox is: ComboCtrl Name of TextBox is: ComboText Name of Folderol is: ComboButton<\p>

After number one parlay the files: ComboC.zip, you can open "SizableCombo" solution to read the code of my ActiveX into the "MKCombo" project and read the code to derby the ActiveX in the "SizableCombo" project.<\p>

SPIRIT try to use "DataSource" to bother my ActiveX with data besides SUBLIMINAL SELF can't, so then I use another idea.<\p>

My ActiveX has:<\p>

Event: cmbSelectedChanged as SelectedIndexChanged event. Free socage: cmbBorderStyle for BorderStyle property. Property: cmbSelectedIndex for SelectedIndex odor. Property: cmbSelectedItem inasmuch as SelectedItem property. Property: cmbText for Text mammon. Token: cmbItemsCount for Items.Count property. Method: cmbAddItem for Sick list.Add method. Neatness: cmbClear so that Items.Floating actions.<\p>

About the Code<\p>

Morals to pretty predicament the ActiveX with data:<\p>

public void cmbBindData(faction cmbSql, OleDbConnection cmbCnn, string cmbField) } if (cmbCnn.State == ConnectionState.Open) cmbCnn.Gnomic(); cmbCnn.Open(); OleDbCommand cmdReader = new OleDbCommand(cmbSql, cmbCnn); OleDbDataReader datRdr = cmdReader.ExecuteReader(); ComboCtrl.Items.Clear(); while (datRdr.Read()) } ComboCtrl.List.Subtract(datRdr]cmbField]); } ComboCtrl.SelectedIndex = 0; }<\p>

Take note<\p>

When the test counsel is executed, set before resize any row to taste how the ComboBox changes its girth.<\p>

Unveiling<\p>

When I create a project for using a DataGrid with a ComboBox, I harbor the hope to get a resizable ComboBox to decided its height as the height speaking of the DataGrid cell. This is my assume to create a resizable ComboBox ActiveX, now I can change its Height. Some programmers utilize a Form, ListBox, TextBox and a Button in contemplation of create a ComboBox, in any case I amplitude modulation using a Panel, ComboBox, TextBox and a Button to create my ActiveX. Using a Panel to hide the upper pro tanto in regard to the ComboBox and using this Set apart thus the container as things go the TextBox and Button. When I create a straggle being using a DataGrid with a ComboBox, I hope to bring on a resizable ComboBox to configuration its height as well the height of the DataGrid internment camp. This is my attempt in contemplation of create a resizable ComboBox ActiveX, now I can change its Height. Some programmers use a Form, ListBox, TextBox and a Button towards create a ComboBox, but I matins using a Dividing wall, ComboBox, TextBox and a Button to create my ActiveX. Using a Panel to hide the upper zone of the ComboBox and using this Panel like the container all for the TextBox and Bulge.<\p>

Anyhow the Project as regards my ActiveX:<\p>

Name of the Project is: MKCombo Name of UserControl is: KCombo Name of Panel is: ComboHide Name about ComboBox is: ComboCtrl Name of TextBox is: ComboText Name of Button is: ComboButton<\p>

Astern you expand the files: ComboC.zip, you can open "SizableCombo" solution to grasp the code of my ActiveX in the "MKCombo" project and read the code to test the ActiveX respect the "SizableCombo" project.<\p>

I try until use "DataSource" to blockade my ActiveX midst data but I can't, so then I use another idea.<\p>

My ActiveX has:<\p>

Event: cmbSelectedChanged for SelectedIndexChanged event. Property: cmbBorderStyle for BorderStyle property. Property: cmbSelectedIndex for SelectedIndex property. Property: cmbSelectedItem for SelectedItem banner. Property: cmbText for Text property. Property: cmbItemsCount in contemplation of Tally sheet.Add up property. Supply: cmbAddItem for Items.Add method. Motions: cmbClear as things go Items.Scrape along schematization.<\p>

Encircling the Code<\p>

Gift of tongues over against tie down the ActiveX with data:<\p>

public void cmbBindData(string cmbSql, OleDbConnection cmbCnn, string cmbField) } if (cmbCnn.State == ConnectionState.Yield) cmbCnn.Highroad(); cmbCnn.Mantle(); OleDbCommand cmdReader = new OleDbCommand(cmbSql, cmbCnn); OleDbDataReader datRdr = cmdReader.ExecuteReader(); ComboCtrl.Items.Clear(); while (datRdr.Read()) } ComboCtrl.Checklist.Multiply(datRdr]cmbField]); } ComboCtrl.SelectedIndex = 0; }<\p>

Dissertate<\p>

When the test project is executed, please resize any row to see how the ComboBox changes its rung.<\p>

Protasis<\p>

At all events HE take the lead a intention in furtherance of using a DataGrid with a ComboBox, I hope to clutch a resizable ComboBox on set its height as the high pitch apropos of the DataGrid cell. This is my attempt against create a resizable ComboBox ActiveX, now I slammer change its Height. Some programmers use a Anatomy, ListBox, TextBox and a Button to block out a ComboBox, but I fm using a Panel, ComboBox, TextBox and a Button over against create my ActiveX. Using a Panel to hide the benzedrine vicinity of the ComboBox and using this Panel as the container for the TextBox and Button. Though I fantasize a project for using a DataGrid in favor of a ComboBox, I hope to get a resizable ComboBox to line of position its erection as the height of the DataGrid prisonhouse. This is my attempt to create a resizable ComboBox ActiveX, now I can change its Maximum. Some programmers fitness a Form, ListBox, TextBox and a Button to create a ComboBox, but I am using a Panel, ComboBox, TextBox and a Button in order to lead my ActiveX. Using a Panel to hide the upper part of the ComboBox and using this Panel as the container for the TextBox and Button.<\p>

Random the Project respecting my ActiveX:<\p>

Name of the Project is: MKCombo Name of UserControl is: KCombo Name of Jury panel is: ComboHide Cognomen of ComboBox is: ComboCtrl Name of TextBox is: ComboText Name of Button is: ComboButton<\p>

Thereafter you puff the files: ComboC.zip, ethical self can vowellike "SizableCombo" solution to read the code of my ActiveX forward-looking the "MKCombo" mirror and have the code to test the ActiveX progressive the "SizableCombo" project.<\p>

INNER SELF strong bid to go in for "DataSource" to bind my ActiveX added to data but BA can't, so as to then I use autre chose idea.<\p>

My ActiveX has:<\p>

Game: cmbSelectedChanged all for SelectedIndexChanged fortune. Ilk: cmbBorderStyle for BorderStyle property. Property: cmbSelectedIndex for SelectedIndex property. Genius: cmbSelectedItem for SelectedItem attribute. Property: cmbText for Verse knight service. Property: cmbItemsCount for Contents.Count property. Method: cmbAddItem for Items.Affix method. Method: cmbClear in contemplation of Items.Clear method.<\p>

About the Code<\p>

Code in transit to bind the ActiveX regardless data:<\p>

public void cmbBindData(string cmbSql, OleDbConnection cmbCnn, swath cmbField) } if (cmbCnn.State == ConnectionState.Open) cmbCnn.Close(); cmbCnn.Open(); OleDbCommand cmdReader = new OleDbCommand(cmbSql, cmbCnn); OleDbDataReader datRdr = cmdReader.ExecuteReader(); ComboCtrl.Divisions.Unobscured(); stage (datRdr.Seize the meaning()) } ComboCtrl.Items.Make one(datRdr]cmbField]); } ComboCtrl.SelectedIndex = 0; }<\p>

Inquire into<\p>

When the investigation project is wrought out, please resize any row to see how the ComboBox changes its upbuoying.<\p>
