Overriding GridDataBound

[Unknown]

In an overridden datagrid, I am overriding the DataSource property, so that on changing the source in design mode, the GridBoundColumns will automatically populate.

The following code works fine

Public Overrides Property DataSource() As Object
Get
Return _datasource
End Get
Set(ByVal Value As Object)
_datasource = Value
MyBase.DataSource = Value

If Me.DesignMode AndAlso Not Value Is Nothing Then
If Me.GridBoundColumns.Count = 0 Then
If Value.GetType.IsSubclassOf(GetType(DataTable)) Then
For Each dc As DataColumn In CType(Value, DataTable).Columns
Dim gbc As New GridBoundColumn
With gbc
.MappingName = dc.ColumnName
.HeaderText = dc.ColumnName
.ReadOnly = dc.ReadOnly
.StyleInfo.CellValueType = dc.DataType
.Owner = Me.Binder

If dc.DataType Is GetType(Date) Then
.StyleInfo.CellType = "MonthCalendar"

ElseIf dc.DataType Is GetType(Boolean) Then
.StyleInfo.CellType = "CheckBox"
.StyleInfo.HorizontalAlignment = GridHorizontalAlignment.Center

Else
.StyleInfo.CellType = "TextBox"
End If

If dc.DataType Is GetType(Decimal) Or dc.DataType.GetType Is GetType(Double) Then
.StyleInfo.Format = "#,##0.00;-#,##0.00;-"
.StyleInfo.HorizontalAlignment = GridHorizontalAlignment.Right
End If

End With

Me.GridBoundColumns.Add(gbc)

Next
End If
End If
End If
End Set
End Property

However, I would like to be able to automatically set the "name" of the column, based on the MappingName, i.e. "col" & MappingName at the time that the column is added to the collection. How would I go about doing this?

Many thanks in advance

I am not sure I fully understand what you want.

There is a GridDataBoundGrid.GridBoundColumns.CollectionChanged event you can try to catch to see if that will allow you to do what you want.

I attach my attempt at overriding the grid.

In the overridden Set DataSource property I have placed a comment to you better explaining what I'm trying to do.

Many thanks
