Edit /Insert with popup and hidden column

[Russell]

I have a grid that has a hidden column (the Id) 

 

<telerik:GridBoundColumn DataField="Id" Display="False" Visible="false"
           FilterControlAltText="Filter column column" UniqueName="column" >
       </telerik:GridBoundColumn>

This works fine for the grid, however when I edit or add a new record (in a popup) the Id shows up.  I can set ReadOnly="true"  which works fine for inserting a new record, this however does not work for editing an existing record.  When ReadOnly is set to true I am unable to get the Id of the record for an update. 

What am I missing here?

Thanks

Hello,

If you set ReadOnly property of a column as true, then it is not possible to update. Take a look into the Visibility and rendering of columns section in the following documentation for more.
Using Columns

Thanks,

I re-read the documentation and I still have noway to hide the column for the "Id" durring an edit or insert.

Hi Russell,

I have assembled a sample project demonstrating the desired functionality. The code below demonstrates the main logic. The solution is to change the ReadOnly property depending on the CommandName.

protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.InitInsertCommandName)
    {
        GridBoundColumn column = this.RadGrid1.MasterTableView.GetColumn("CategoryID") as GridBoundColumn;
        column.ReadOnly = true;
        RadGrid1.EditIndexes.Clear();
    }
    else if (e.CommandName == RadGrid.EditCommandName)
    {
        GridBoundColumn column = this.RadGrid1.MasterTableView.GetColumn("CategoryID") as GridBoundColumn;
        column.ReadOnly = false;
        RadGrid1.MasterTableView.IsItemInserted = false;
    }
}

Additionally, you could go through the Custom Edit Forms and Different Edit Forms on Edit and Insert sections in the help articles below:

• http://www.telerik.com/help/aspnet-ajax/grid-custom-edit-forms.html
• http://www.telerik.com/help/aspnet-ajax/grid-different-edit-forms-on-edit-and-insert.html

The second topic elaborates on how you can use difference edit forms for edit and insert. Another option is to define your own edit for through the FormTemplate where would you have full control on what controls to display in the different modes.
