The event handler receives an argument of type AddingDataRowEventArgs containing data related to this event. The following AddingDataRowEventArgs properties provide information specific to this event.
Gets a reference to the DataRow object being built.
Remarks
When bound to a data source, the AddingDataRow event is raised for each row found in the data source. When in unbound mode (providing data manually), it is raised once for each DataRow added using the Xceed.Grid.Collections.DataRowList.AddNew method afterEndEdit is called in order to provide data to each cell in the row.
Example
The following example demonstrates how to create a grid whose data is provided manually
using the AddingDataRow event.
' Add the desired number of columns to the grid.
' In the case, we will only add 4
gridControl1.Columns.Add( New Column( "column1", GetType( Integer ) ) )
gridControl1.Columns.Add( New Column( "column2", GetType( Integer ) ) )
gridControl1.Columns.Add( New Column( "column3", GetType( Integer ) ) )
gridControl1.Columns.Add( New Column( "column4", GetType( Integer ) ) )
' Subscribe to the AddingDataRow event
AddHandler gridControl1.AddingDataRow, AddressOfMe.grid_AddingDataRow
' Add the desired number of DataRow objects to the grid's collection of datarows
Dim i AsIntegerFor i = 0 To 50
gridControl1.DataRows.AddNew().EndEdit();
' AddNew will return a reference to a new DataRow object whose
' cell values we can fill immediately, for the purposes of this
' example we will use the AddingDataRow event instead.
'
' Xceed.Grid.DataRow row = gridControl1.DataRows.AddNew()
' row.Cells( 0 ).Value = 26
' row.Cells( 0 ).Value = 27
' row.Cells( 0 ).Value = 28
' row.Cells( 0 ).Value = 29
' row.EndEdit();
' etc...
