Hi Kingsley,
If the exception is of a validation one, like the column type is an into and the user enters input other than numbers, then you may use the custom validation.
Please refer this forum and KB for more details and avoid raising a message box.

If that exception is something unwanted, you can ignore it through ResumeCatchExceptions.
using Syncfusion.Windows.Forms;
ExceptionManager.ExceptionCatched += new ExceptionCatchedEventHandler(ExceptionManager_ExceptionCatched);
void ExceptionManager_ExceptionCatched(object sender, ExceptionCatchedEventArgs e)
{
ExceptionManager.ResumeCatchExceptions();
}
Let me know if your requirement is different.
Best regards,
Stanley
