[Solved] Can't execute CancelConfirmed in RadGrid ItemCommand event if Grid has No Rows.

[gc_0620]

Folks
using RadControls for ASP.NET AJAX Q3 2013 with VStudio 10. I am using below link as Prototype.

http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/form-template-update/defaultcs.aspx

My Radgrid has Filter enabled.  Below are my steps to reproduce the error:

1) Filtered the Grid with some condition; Grid has no Rows.
2) Clicked Add New Command Item link Button.
3) Now can't Cancel Insert operation from Form Template.  Edit Form Stays open.
4) But if Grid has some rows, Cancel Insert operation works perfectly.

Below is my Code. Any help will be appreciated.

Thanks

Hi,

I guess you want to show a Confirm on the Cancel button. Please take a look at the following code snippet.

ASPX:

<asp:Button ID="btnCancel" Text="Cancel" runat="server" CausesValidation="False" CommandName="CancelInsert" OnClientClick="radconfirm('The selected application(s) will be deleted.\n\nClick OK to confirm.', callBackFn, null, null, '', 'Cancel');return false;">
</asp:Button>

C#:

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
  if (e.CommandName == "CancelInsert")
  {
    e.Canceled = true;
  }
}

JS:

<script type="text/javascript">
  function callBackFn(confirmed) {
    if (confirmed) {
      $find('<%= RadGrid1.ClientID %>').get_masterTableView().fireCommand("CancelInsert");
      }
    }
</script>

Thanks,
Princy

Thanks so much Princy. As always your suggestion is sincerely appreciated..

Hi all,

How do you implement the same solution for Child Table? This above solution works perfectly for Master Table but unfortunately it is not working for Child Table. Cancel Insert operation from Form Template Edit Form Stays open for Child Table.

Hi,

You can set the same Cancel button for all the InsertForm, and set the CommandName to something else other than "CancelInsert".

ASPX:

<asp:Button ID="btnCancel" Text="Cancel" runat="server" CausesValidation="False" CommandName="CancelInsertForm" OnClientClick="radconfirm('The selected application(s) will be deleted.\n\nClick OK to confirm.', callBackFn, null, null, '', 'Cancel');return false;">
</asp:Button>

JS:

<script type="text/javascript">
  function callBackFn(confirmed) {
   if (confirmed) {
     $find('<%= RadGrid1.ClientID %>').get_masterTableView().fireCommand("CancelInsertForm");
    }
  }
</script>

C#:

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
  if (e.CommandName == "CancelInsertForm")
  {
    e.Canceled = true;
    e.Item.OwnerTableView.IsItemInserted = false;
    e.Item.OwnerTableView.Rebind();
  }
}

Thanks,
Princy
