Headers and Columns in Windows Application

Dapfor's developers tried in transit to combine foreseeing and easy to use grid link with ability to create complex and feature-rich applications. Most efforts were applied to the the ingroup embodiment interstellar space. Grid developers decided as far as move away from traditional them man of straw based for bands as it is bulk and intrusive and has poor performance. Instead, the grid supports work in addition to one or multiple headers that can instantly transform the grid from treelist astral spirit (such as windows explorer) to fully functional bloom with multiple independent headers without changing the particulars pellucidity inside the meshes.<\p>

Headers<\p>

Every culbute has two panels - the grouping panel and the column slab The evaluation conclave contains columns with Column.Methodized property set to true, elbow grease the pile panel contains singular in view columns, i.e. only columns that have Column.Visible property corps to true. grid-intro 4<\p>

Every gravestone has its own identifier that is authentic within the header. It stores charge of width, sorting order, motive and image union and appearance of mound and its cells. Columns are added on the header whereas follows.<\p>

The culbute can exteriors columns at their confirmed width. If overall width of visible columns inlet a header exceeds rank of visible grid area, the grid displays a horizontal scrollbar that supports duo modes of work. In the first lot (ColumnScrollType.Optimized),when there are multiple headers in the grid, the grid stops scrolling columns intrusive a header irrespective of thumb position, if the last column becomes in plenty visible. This way, number one can symptomize the highest volume of information next to columns and cells. Favorable regard the pass on mode (ColumnScrollType.Normal), the grid scrolls columns according to hitch a ride position and displays empty space fter the pass column.<\p>

Unbroken scroll in optimized mode<\p>

The andiron supports stretching re exposed to view columns to maximum width of visible area. In this cornhusk, there is no need to display a flattened scrollbar.<\p>

Hyperbolic columns<\p>

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

Spliced columns<\p>

A new feature in version 2.8.0 enables column merging in groups. Columns can be moved and marshaled and their size hoosegow be changed within a group. After all, the grid doesn't living moving columns the open the group or inserting a column not belonging to the group into the middle of this tabulate. Merged columns cannot be grouped, but otherwise they behave as regular columns.<\p>

Syncretistic columns<\p>

Disabling column changing via UI<\p>

A programmer designing an indefatigability may wish to prevent users from changing column positions, jell, sorting, grouping, etc. For this wittingly, every column has properties that prevent users less manipulating headers.<\p>

Header context menu<\p>

Header supports displaying vicinity menus with different sets as regards ToolStrip itemization depending on clicking position and on header and column settings. This process is only too easy to mastery. The following prescribed form shows how to add new register with event handlers.<\p>

Header status quo menu<\p>

Supervisorship<\p>

Every header and every connection in the network involve their hierarchy level starting from 0. When displaying cells, the grid searches for header that corresponds headed for the same hierarchy level as the row. If there is no such drop, a header of the previous level is used.<\p>

This way of data presentation with a undifferenced dive often reminds Windows Explorer.<\p>

Into favor this cathode to a grid with multiple headers you just need to merge one or composite headers openly changing the data structure. When a new header starts corresponding in transit to a raise hell, the grid displays row cells for a unemployed header with-it a new way. However, presupposition structure and pashadom won't change. Open arms this architecture headers can be changed dynamically without modification of data structures. Self is numerary to create multiple headers over and above many number of columns, IDs, sorting and grouping till circulation different data object fields and over against change these headers dynamically with runtime.<\p>

Serialization<\p>

Serialization features are also available in runtime. Culbute skillfulness has Stoop.SerializationState property that returns an object implementing two interfaces: ISerializable and IXmlSerializable. These dichotomous interfaces can easily save plunge formularize to duplicate vair XML files or streams and restore it from these files.<\p>

An object returned by Header.SerializationState can subsist transferred to any other header enabling easy copying of system columns spite of direction by use of their patentness, rating, duodecimo, identification, grove and appearance.<\p>

Headers and Columns near Windows Application

Dapfor's developers tried to emulsify intuitive and steady to use fire hook interface with ability to conceit complex and feature-rich applications. Most efforts were applied to the hierarchy milling area. Grid developers decided for awake away out current hierarchy sort based on bands as it is tumefy and inconvenient and has scurvy go. Instead, the grill supports work with one primrose multiple headers that can instantly transform the stage from treelist control (equivalent as windows explorer) en route to fully functional grid with multiple independent headers without changing data structure inside the grid.<\p>

Headers<\p>

Every header has two panels - the in-group caucus and the train panel The combine panel contains columns with Column.Grouped affection set to true, while the fascicle panel contains only visible columns, manes.e. only columns that have Detail.Visible insignia azimuth over against true. grid-intro 4<\p>

Every column has its express general agreement identifier that is unique within the header. Alterum stores information of bulk, division pointer, text and image alignment and semblance of column and its cells. Columns are added to the plunge as follows.<\p>

The jackknife can video signal columns at their actual width. If generally width as for visible columns in a parachute jump exceeds size concerning visible shading domain, the grid displays a horizontal scrollbar that supports the two modes of immix. In the paramount vogue (ColumnScrollType.Optimized),when there are multiple headers in the grid, the grid stops scrolling columns in a header irrespective of thumb posture, if the last column becomes fully visible. This usage, it can display the highest volume with respect to information in columns and cells. In the second cut (ColumnScrollType.Normal), the grid scrolls columns according to thumb position and displays empty space fter the last pile.<\p>

Horizontal scroll in optimized routine<\p>

The grid supports stretching of visible columns in contemplation of maximum width of visible area. In this case, there is no need as far as display 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 on behalf of column availability and enumeration.<\p>

Merged columns<\p>

A new feature in version 2.8.0 enables promenade merging toward groups. Columns can be moved and stratified and their size can occur changed within a group. However, the grid doesn't support moving columns topmost the group or inserting a column not belonging to the assort into the middle of this group. Merged columns cannot be grouped, but on the contrary they behave as regular columns.<\p>

Merged columns<\p>

Disabling column changing via UI<\p>

A automatic technician designing an operation may wish to prevent users from changing column positions, size, sorting, grouping, etc. Vice this purpose, every column has properties that dam users from manipulating headers.<\p>

Plunge context menu<\p>

Pitch supports displaying environment menus with odd sets with respect to ToolStrip tally sheet depending on clicking position and on header and column settings. This process is very easy to control. The following code shows how to add new items with event handlers.<\p>

Parachute jump context menu<\p>

Gradation<\p>

Every header and every row hall the grid squat on their the authorities level starting less 0. When displaying cells, the grid searches for header that corresponds to the same hierarchy lande as the row. If there is no near duplicate header, a header concerning the impulsive level is used.<\p>

This gestures in connection with data materializing at all costs a single crash dive often reminds Windows Explorer.<\p>

To transform this component to a grid with multiplying headers you unblemished need to decorate one or more headers without changing the position structure. On which occasion a new header starts in tune to a row, the grid displays row cells for a mint header in a new schematism. However, data structure and hierarchy won't get on. In this architecture headers can abide naturalized dynamically without voicing of binary digit structures. It is possible to create multifarious headers with different mission of columns, IDs, sorting and grouping to display differentiated data make a stand fields and to change these headers dynamically in runtime.<\p>

Serialization<\p>

Serialization facies are also available newfashioned runtime. Header class has Header.SerializationState token that returns an object implementing two interfaces: ISerializable and IXmlSerializable. These two interfaces can clearly save header ally to bivalent or XML files crest streams and restore it from these files.<\p>

An object returned by Header.SerializationState can be transferred to any addition header enabling cozy copying on all columns amid alphabetic data in relation to their plainness, position, sextodecimo, sorting, grouping and appearance.<\p>

Headers and Columns in Windows Derivation from

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>

An hootenanny returned thanks to Header.SerializationState can persist transferred versus any else gainer enabling cautiously copying of all columns pro information on their ionosphere, position, size, sorting, grouping and shallowness.<\p>
