I just converted over from 8.1 to 8.2 and the WinGrid is giving me a new error. For some reason the grid is calling the InitializeTemplateAddRow when the form closes. It wasn't doing that before (or at least not causing an exception). InitializeTemplateAddRow is called after the data source has been disposed and I get a key not found error. I added the isFormClosing test to fix it but I shouldn't have to do this. What's going on?

private void ultraGrid1_InitializeTemplateAddRow(object sender, InitializeTemplateAddRowEventArgs e)
{
            if(this.isFormClosing)
                return;
            
            e.TemplateAddRow.Cells["CreatedOn"].Value = DateTime.Now;

            ...

}
