Added By: Rabab Siblini at: 3/16/2016 11:18:39 PM Tanks, it works exactly as I want , but I didn't user the exception class , I check it as such :
protected void gvDiscounts_RowDeleting(object sender, DevExpress.Web.Data.ASPxDataDeletingEventArgs e) { if (CannotDelete) throw new Exception("DeleteError"); }
protected void gvDiscounts_CustomErrorText(object sender, ASPxGridViewCustomErrorTextEventArgs e) { if (e.Exception.Message == "DeleteError") e.ErrorText = e.Exception.Message; } Added By: Vova (DevExpress Support) at: 3/17/2016 1:57:07 AM
