In GridView control you can add the Link Button control to implement the Javascript Confirm message box over the Delete command event. You can set the CommandName property of Link Button control equal to "Delete" to attach the RowDeleting event of GridView control that executes the server side VB.Net code for deleting the data record. The JavaScript confirm box shows two buttons such as Ok and Cancel. When the user clicks Cancel button then it prevents the server side event to occur whereas when user clicks the OK button then it permits the execution of server side VB.Net code to perform the delete action for the targeted record item.
