I am developing one windows application. in one of the page i am using Telerik.WinControls.UI.RadGridView and added Edit and Delete button in grid. While first time my page appears i click on "Delete" button, it shows MessageBox.Show message with confirmation "Yes" and "No" buttons. while i click on No button it works as expected. While i click on "Edit" button it open new form in window and save and close that form. now rebind grid in "Edit" and "Delete" button. Now, if i click on delete button, it asks for MessageBox.show with confirmation "Yes" and "No" buttons. While i click on "No" button message box appear twice. while user clicks on "NO" we called "return". still its not working. Can anyone please help me out for this issue. Need help ASAP.
