Telerik RadGrid set BoundColumn to ReadOnly in Edit Mode

Question

I have a Telerik RadGrid that has three bound columns and one button column. I would like to let the user edit the values in only one of the bound columns. The user can add a new record so i can't set the two bound column to read only. Is there anyway i can do this in the ASPX or do i have to do it in the code behind? I have some code that is working but it is not the best.

Here's my code:

Case "Edit"
    Dim aoeAnswerCode As GridBoundColumn = CType(e.Item.OwnerTableView.GetColumn("aoeAnswerCode"), GridBoundColumn)
    aoeAnswerCode.ReadOnly = True

Case "Update", "PerformInsert"
    For Each column As GridColumn In e.Item.OwnerTableView.RenderColumns
        If TypeOf column Is IGridEditableColumn Or column.UniqueName = "aoeAnswerCode" Then

Code tip: Use `OrElse` instead of `Or`, almost always. – Ry- Jan 08 '12 at 01:22 — Ry-, Jan 08 '12 at 01:22

Simply set the ReadOnly property to true. See the example below:

<telerik:GridBoundColumn DataField="Datetime" HeaderText="Date" 
 DataFormatString="{0:MM/dd/yyyy}" ReadOnly="True">  
</telerik:GridBoundColumn>

In my case, this also hides the column in `radgrid`'s `Edit Form` and it won't let me use it as parameter in `SqlDataSource`. – fdkgfosfskjdlsjdlkfsf Sep 18 '18 at 18:25

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item.IsInEditMode && e.Item is GridEditFormItem)
