Hi,
I want to add commandbutton to each radgridview row, and I want to know how to define each row's button click event ?
For example, If I click on button of row 3, the button shows a string in the cell instead and if clicked back again, the button hides string and shows itself.
I use vb.net
Thanks

Hello George,
I can suggest you to use GridViewCommandColumn which displays a button element on every row in RadGridView. The column responds to user input mouse clicks via the CommandCellClick event. You can handle the CellFormatting event in order to change the appearance of the button element and show the text that you want. Please refer to the following example which demonstrates this approach:
PrivateSub SurroundingSub()
Dim commandColumn As GridViewCommandColumn = New GridViewCommandColumn()
commandColumn.Name = "CommandColumn"
commandColumn.FieldName = "Title"
commandColumn.HeaderText = "CommandColumn"
radGridView1.MasterTemplate.Columns.Add(commandColumn)
AddHandler radGridView1.CommandCellClick, AddressOf RadGridView1_CommandCellClick
AddHandler radGridView1.CellFormatting, AddressOf RadGridView1_CellFormatting
AddHandler radGridView1.CellClick, AddressOf RadGridView1_CellClick
EndSub
Private Sub RadGridView1_CellClick(ByVal sender As Object, ByVal e As GridViewCellEventArgs)
If TypeOf e.Column Is GridViewCommandColumn Then
If radGridView1.CurrentCell.Tag IsNot Nothing Then
radGridView1.CurrentCell.Tag = Nothing
Me.radGridView1.TableElement.Update(GridUINotifyAction.StateChanged)
End If
End If
End Sub
Private Sub RadGridView1_CellFormatting(ByVal sender As Object, ByVal e As CellFormattingEventArgs)
If TypeOf e.CellElement Is GridCommandCellElement Then
Dim cell As GridCommandCellElement = TryCast(e.CellElement, GridCommandCellElement)
cell.DrawText = True
cell.Text = "Test"
If cell.Tag IsNot Nothing Then
cell.CommandButton.Visibility = ElementVisibility.Collapsed
Else
cell.CommandButton.Visibility = ElementVisibility.Visible
End If
End If
End Sub
Private Sub RadGridView1_CommandCellClick(ByVal sender As Object, ByVal e As GridViewCellEventArgs)
Dim cell As GridCommandCellElement = TryCast(sender, GridCommandCellElement)
If cell.Tag Is Nothing Then
cell.Tag = "Clicked"
End If
Me.radGridView1.TableElement.Update(GridUINotifyAction.StateChanged)
End SubI hope this helps. Should you have any other questions do not hesitate to ask.
