Cancel SelectedIndexChanged event server-side

[Jeremy]

Hi

Is there any way to cancel a user selecting another row in a radgrid with server-side validation? I want to allow the user to select a row in the grid, but only if some other textboxes are valid.
eg:
Markup:

<asp:TextBox ID="txtDummy" runat="server" />

<telerik:RadGrid ID="rgProjects" runat="server"

      OnNeedDataSource="rgProjects_NeedDataSource"

      OnSelectedIndexChanged="rgProjects_SelectedIndexChanged">

   <ClientSettings Selecting-AllowRowSelect="true" EnablePostBackOnRowClick="true">

      <Scrolling AllowScroll="true" SaveScrollPosition="true" />

   </ClientSettings>

</telerik:RadGrid>

Code behind:

protected void rgProjects_SelectedIndexChanged(object sender, EventArgs e)

{

   Boolean result = CheckProjectChanges(txtDummy.Text);

   if (result == true)

      //continue with stuff - easy


   else

      //cancel row select! how??

}

Hello Jeremy,

Try the following code snippet to achieve your scenario.

C#:

protected void RadGrid1_SelectedIndexChanged(object sender, EventArgs e)
    {
        var dataItem = RadGrid1.SelectedItems[0] as GridDataItem;//accessing selected row
        if(condition)
        dataItem.Selected = false;
    }

Thanks,
Princy.
