Closing insert template

[Christopher]

I'm developing a grid based largely on http://demos.telerik.com/aspnet-ajax/grid/examples/programming/commanditem/defaultcs.aspx

I need to be able to programatically abort inserting a record, and close the insert items template so that the user no longer sees the controls used for inserting. In the grid's ItemCommand, event, I want to do something like this:

 

public void radGrid_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    switch (e.CommandName.ToString())
    {
         case "PerformInsert":
         {
               //do something to determine if I can insert a record
               //if I can not insert a record
               //How do I close the insert items template?

 

I've tried e.Cancelled = true; but that doesn't seem to work. At this point, I successfully abort the insert, but the user continues to see the insert controls. She/he has to click the insert template's cancel button to close them.

Thanks!

Here's the grid markup:

Hello Christopher,

I was not able to reproduce the issue on my side. I prepared a small sample and attached it to this forum post. As you can see when the insert command is canceled OnItemCommand event the insert form will not be opened. Could you please give it a try and let me know how it differs from your real setup?

Kind regards,
