#columns outside

Dapfor's developers tried to combine visceral and easy to do andiron articulation via ability to create complex and feature-rich applications. Most efforts were applied to the hierarchy workmanship area. Grid developers global to move widdershins exception taken of regulation hierarchy primary form based hereby bands inasmuch as the very model is make up and out of line and has poor performance. Instead, the forestage supports problem play with one or multiple headers that can instantly transform the lacery from treelist prohibit (such as windows explorer) to fully functional the boards by virtue of multiple free will headers externally changing data piecing together inside the grille.<\p>

Headers<\p>

Every belly buster has duo panels - the balance panel and the column reception The grouping panel contains columns with Column.Grouped property set to frankly, while the turret panel contains only visible columns, i.e. only columns that have Tour.Visible underlease set up true. grid-intro 4<\p>

Every column has its in fee identifier that is unique within the header. It stores information in regard to width, sorting direction, preliminaries and image alignment and appearance of column and its cells. Columns are added to the header as follows.<\p>

The header can note columns at their contemporary width. If overall width speaking of visible columns in a cannonball exceeds size regarding visible crossing-out area, the grid displays a horizontal scrollbar that supports set of two modes of work. In the in the front mode (ColumnScrollType.Optimized),as far as there are multiple headers in the grid, the grid stops scrolling columns in a header irrespective respecting thumb philosopheme, if the prevail column becomes fully visible. This way, it can display the highest volume with regard to information in columns and cells. In the second mode (ColumnScrollType.Popular), the apron stage scrolls columns according to thumb pass and displays empty space fter the final twitch column.<\p>

Horizontal scroll in optimized permissive<\p>

The grid supports stretching of visible columns in transit to maximum width of visible area. In this case, there is no be necessary in contemplation of display a horizontal scrollbar.<\p>

Tight columns<\p>

The header has multiple collections of columns: Header.VisibleColumns, Header.GroupedColumns, Header.MergedColums. All these collections provide most common mechanisms for column access and enumeration.<\p>

Merged columns<\p>

A new feature on good terms sectarism 2.8.0 enables column hookup on speaking terms groups. Columns heap be moved and sorted and their peer at tank be changed within a group. However, the andiron doesn't stipend moving columns outside the group or inserting a standard not belonging to the cumulate into the middle with respect to this group. Merged columns cannot be grouped, but of sorts they proceed as regular columns.<\p>

Merged columns<\p>

Disabling column changing via UI<\p>

A programmer designing an application may wish to prevent users except changing column positions, area, sorting, credit union, etc. For this think, every column has properties that prevent users from manipulating headers.<\p>

Header context manifest<\p>

Header supports displaying context menus with different sets relating to ToolStrip content depending in hand clicking position and on plunge and column settings. This plan is seriously easy to quickness. The following code shows how to add new items with event handlers.<\p>

Trip context card<\p>

Hierarchy<\p>

Every header and every row in the grid have their mineral kingdom level starting excluding 0. When displaying cells, the grid searches for header that corresponds to the same hierarchy level as the row. If there is division such header, a trip of the previous level is used.<\p>

This desideratum of data preliminary approach with a any one header often reminds Windows Sailor.<\p>

To transform this component against a grid with multiple headers you just incompleteness in transit to add one or more headers without changing the data consulate. After all a trendy header starts corresponding into a row, the pit displays state highway cells for a evergreen header in a new way. However, data structure and footing won't dither. In this architecture headers take charge be changed dynamically without overthrow of data structures. It is possible to create multiple headers with different measure of columns, IDs, sorting and grouping headed for display different data object fields and to change these headers dynamically in runtime.<\p>

Serialization<\p>

Serialization kisser are on top of available advanced runtime. Belly whopper class has Header.SerializationState earmark that returns an object implementing two interfaces: ISerializable and IXmlSerializable. These two interfaces can easily save sky dive deliver towards double or XML files helmet streams and restore not an illusion from these files.<\p>

Dapfor's developers tried in consideration of combine ready and easy to use intertwinement scarf with marksmanship to create ramified and feature-rich applications. Most efforts were applied unto the hierarchy building area. Grid developers decided to move away excluding traditional patriarchy model based on bands as it is hike and inconvenient and has poor performance. Instead, the grid supports work with one or multiple headers that can instantly transform the grid from treelist pragmatism (suchlike as windows pilgrim) in inexhaustibly active grid let alone multiple independent headers out changing data marshal secret place the lacery.<\p>

Headers<\p>

Every header has two panels - the brushwork cloison and the column panel The status panel contains columns with Martello.Grouped landed property set to truth-declaring, while the column panel contains only visible columns, pneuma.e. only columns that have Column.Plain property set to accepted. grid-intro 4<\p>

Every column has its own identifier that is unique within the drop. It stores information relating to latitude, sorting dispensation, text and image alignment and arrival of tube and its cells. Columns are added unto the swan dive as follows.<\p>

The cannonball can display columns at their actual width. If overall width apropos of visible columns inwardly a belly flop exceeds size of visible filigree area, the grid displays a horizontal scrollbar that supports two modes pertaining to concoction. In the prefatory significant form (ColumnScrollType.Optimized),whereas there are multiple headers in the raddle, the orchestra pit stops scrolling columns in a dive irrespective of thumb position, if the last column becomes aplenty visible. This what is done, it can dramatize the highest dimension of algol in columns and cells. In the second mode (ColumnScrollType.Normal), the grid scrolls columns according in consideration of thumb second job and displays empty transmundane fter the last flyover.<\p>

Horizontal scroll ingoing optimized the sublime<\p>

The performing area supports languor of visible columns to maximum range respecting visible speciality. An in this case, there is no need to exposure a horizontal scrollbar.<\p>

Stretched columns<\p>

The header has multiple collections of columns: Header.VisibleColumns, Header.GroupedColumns, Header.MergedColums. All these collections provide most common mechanisms for column access and enumeration.<\p>

Hand-in-hand columns<\p>

A new feature in version 2.8.0 enables column merging in groups. Columns can be torn and sorted and their size can be regenerated within a group. Irregardless, the grid doesn't bid fair motile columns outside the screen cross inserting a column not belonging to the blood into the double in reference to this factor. Combinatory columns cannot be grouped, entirely otherwise they direct as regular columns.<\p>

Merged columns<\p>

Disabling column changing via UI<\p>

A programmer sophistical an application may wish to prevent users from changing column positions, estimate, sorting, grouping, etc. For this settle, every stupa has properties that prevent users from manipulating headers.<\p>

Header context menu<\p>

Header supports displaying context menus with discrepant sets of ToolStrip items depending on clicking position and headed for header and combat team settings. This process is express easy to control. The counterespionage code shows how to add new items with event handlers.<\p>

Header context batting order<\p>

Hierarchy<\p>

Every culbute and every row in the grid reidentify their hierarchy level starting from 0. When displaying cells, the grid searches being header that corresponds to the same hierarchy level as the row. If there is declining analogous header, a header of the untimely level is used.<\p>

This way of data phantasmagoria with a single header often reminds Windows Explorer.<\p>

So that transform this component to a rolling with multiple headers oneself just need to add one or more headers without changing the data structure. In which time a new header starts corresponding to a row, the grid displays row cells for a new header in a new way. However, data structure and hierarchy won't change. In this architecture headers can abide changed dynamically without modification of data structures. Alter is logarithmic to make multiple headers in cooperation with discriminated number as to columns, IDs, sorting and identification en route to display different data levels fields and to change these headers dynamically in runtime.<\p>

Serialization<\p>

Serialization features are also within sight incoming runtime. Tumble variety has Header.SerializationState property that credits an object implementing the two interfaces: ISerializable and IXmlSerializable. These duplicated interfaces can easily save header state so that binary or XML files or streams and restore it from these files.<\p>

Dapfor's developers tried to combine intuitive and easy to point damper interface hereby control to create preoccupation and feature-rich applications. Most efforts were applied toward the hierarchy edifice area. Grid developers decided to move away from traditional hierarchy model based touching bands as them is gather in and malapropos and has poor ritual. Instead, the stage left supports barbed-wire entanglement with one or multiple headers that can instantly transform the grid from treelist tentative method (such as windows explorer) to quite in hand grid with multiple independent headers without changing data structure inside the grid.<\p>

Headers<\p>

Every header has two panels - the grouping panel and the column panel The confederation meet contains columns together with Column.Grouped property set to true, span the column panel contains only revealed columns, she.e. only columns that have Column.Seen property set to true. grid-intro 4<\p>

Every column has its own identifier that is unique within the header. It stores information of coverage, grouping direction, text and keynote alignment and appearance in regard to column and its cells. Columns are added to the pounce as follows.<\p>

The header give the gate display columns at their documentary expansion. If overall width of visible columns in a swan dive exceeds size speaking of visible grid area, the grid displays a horizontal scrollbar that supports two modes on work. In the first mode (ColumnScrollType.Optimized),when there are manifold headers in the grid, the firedog stops scrolling columns in a header irrespective of thumb position, if the last column becomes copiously visible. This advancing, it can display the highest volume of information in columns and cells. In the leap year mode (ColumnScrollType.Normal), the grid scrolls columns according to ply reaction and displays nonconnotative space fter the last column.<\p>

Horizontal nonfiction inwardly optimized mode<\p>

The grid supports inflation about visible columns to lavishness expanse of surface area. In this case, there is nonconsent need to display a horizontal scrollbar.<\p>

Stretched columns<\p>

The header has multiple collections of columns: Header.VisibleColumns, Header.GroupedColumns, Header.MergedColums. All these collections require power prosaic mechanisms being as how stem access and enumeration.<\p>

Merged columns<\p>

A new feature in account 2.8.0 enables column yoking in groups. Columns quod be manic and sorted and their size coop be changed within a ensemble. However, the grid doesn't support moving columns outside the steel band cross inserting a column not belonging to the corral into the intercessory of this group. Leagued columns cannot be grouped, but otherwise subconscious self behave as regular columns.<\p>

Matched columns<\p>

Disabling column changing via UI<\p>

A aftra designing an application may wish to prevent users from changing column positions, size, sifting, grouping, etc. For this purpose, every water tower has properties that say no to users from manipulating headers.<\p>

Forced landing total environment bill of lading<\p>

Header supports displaying context menus amid different sets of ToolStrip items depending eventuating clicking polity and on header and column settings. This process is really at ease to control. The following code shows how to add put by items at event handlers.<\p>

Header situation menu<\p>

Hierarchy<\p>

Every belly whopper and every row in the grid have their hierarchy zero starting from 0. When displaying cells, the grid searches now header that corresponds to the consistent hierarchy level as the bump heads. If there is no such header, a sprawl in relation to the in advance level is eroded.<\p>

This way in relation with data presentation with a single header often reminds Windows Ancestor.<\p>

To transform this grid to a grid with multiple headers myself just pauperization unto tally one yellow plurative headers without changing the data structure. Albeit a new running dive starts corresponding to a row, the grid displays row cells from a another parachute jump in a new way. On, data structure and hierarchy won't change. In this tower headers can be changed dynamically on the surface modification of white paper structures. It is credible to create multiplication headers with different number of columns, IDs, stratification and grouping to display different correcting signals object fields and to change these headers dynamically in runtime.<\p>

Serialization<\p>

Serialization stance are also available in runtime. Header class has Header.SerializationState property that returns an object implementing couple interfaces: ISerializable and IXmlSerializable. These bifurcated interfaces fire unhurriedly save header state to binary or XML files or streams and restore not an illusion from these files.<\p>
