Hide Columns in EditMode, but Show them on Insert

[Jamal]

Greetings,

I'm working with the ASP.NET AJAX RadGrid, and I'm trying to show certain columns when a user is creating a new record, but I want them to be hidden (or read only) when in EditMode. Does anyone have any good examples of this?

Thanks,

Jamal Khan

Hi Jamal,

Try the following code snippet in order to hide the column in Editmode and show in insert mode.

ASPX:

<Columns>
 . . .
<telerik:GridBoundColumn DataField="CustomerID" HeaderText="CustomerID" SortExpression="CustomerID" UniqueName="CustomerID"></telerik:GridBoundColumn>
 . . .
</Columns>

CS:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
    foreach (GridColumn col in RadGrid1.Columns)
    {
        if (col.ColumnType == "GridBoundColumn" && col.UniqueName == "CustomerID")
        {
            if (e.CommandName == RadGrid.EditCommandName)
            {
                (col as GridBoundColumn).ReadOnly = true;
                col.Visible = false;
            }
            else
            {
                (col as GridBoundColumn).ReadOnly = false;
                col.Visible = true;
            }
        }
    }
}

Thanks,
Shinu.
