[Solved] Conditionally hide EditCommandColumn1 or do not allow Update

[gc_0620]

Hi
Environment: RadControls for ASP.NET AJAX Q3 2009 / VS 2008 SP1/IE7/WINXP SP 2. 

I would like to conditionally hide or disallow the Update  in GridEditFormItem for certain users. For Example If the User is 'PR Manager', all add/update/edit/delete options will be available,  for others Radgrid will be read only.

I can hide the command items template without any problem but the problem is  when the Grid is in GridEditFormItem.   Just can't refer  the  EditCommandColumn1  (null exception error occurs) or hide its update text. 
Ideal solution will be if user is not 'PR Manager', only the cancel option will be available in GridEditFormItem. Below is my Radgrid and  Radgrid_Item Command.

Any help will be appreciated...


Thanks

Hello,

Please try the following code-snippet:

...
if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
{
    /// Allow only Cancel option if not 'PR Manager'
    GridEditFormItem EditFormcmdItem = (GridEditFormItem)e.Item;
    EditFormcmdItem.FindControl("UpdateButton").Visible = false;
}
...

Let me know whether this approach is suitable for your scenario.
