Hi Mehran,

Thank you for writing.

The observed behavior is most likely caused by the missing else statement which is has to reset the element values in the rest of the cases. Please refer to the following help article where this is explained and examples are given: http://www.telerik.com/help/winforms/gridview-cells-formatting-cells.html.

I hope this helps.
 
All the best,

Dim button As RadButtonElement = CType(e.CellElement.Children(0), RadButtonElement)
                       button.Visibility = ElementVisibility.Visible
                       button.BackColor = Color.Peru

Hello Mehran,

That is one way to do that - setting the Visibility to Visible. Another way would be to reset the Visibility property value to its theme setting:

Private Sub radGridView1_CellFormatting(sender As Object, e As CellFormattingEventArgs)
    Dim cmdCellElement As GridCommandCellElement = TryCast(e.CellElement, GridCommandCellElement)
    If cmdCellElement IsNot Nothing Then
        If e.CellElement.RowInfo.Cells("GroupType").Value.ToString() <> "3" Then
            cmdCellElement.Visibility = ElementVisibility.Collapsed
        Else
            cmdCellElement.ResetValue(RadButtonElement.VisibilityProperty, ValueResetFlags.Local)
        End If
    End If
End Sub

I hope this helps.
 
All the best,
