Validate Data for GridView Component
The Kettic DataGridView allows users of the control easily validate data grid cells when data is committed to the data source. To validate data to grid cells and rows, we need to use the ValidateCell event, which will be raised by the Kettic DataGridView when there are any changes to the current cell or when the grid cell loses input focus like. Before we validate data to grid cell, we need to cancel the ValidateCell event to prevent the users from exiting the cell until entering a valid editor value or cancelling the edit process. Meanwhile, we can use the ValidateRow event in the same way to prevent the user from exiting the current row.
