Hello Alok,
The user is allowed to type text with the GridViewTextBoxColumn and the text cannot be converted to Byte and this is why the exception occurs. It would be better to use GridViewDecimalColumn for this case:

var col = new GridViewDecimalColumn();col.Maximum = 255;col.Minimum = 0;col.DataType = typeof(byte);col.FieldName = "ByteColumn";radGridView1.Columns.Add(col);Please let me know if there is something else I can help you with.

Hello Alok,
You can use the DataError event to handle exceptions that occur in the DataSource (e.g. ConstraintException). Such exceptions are handled by the grid and a message box will be displayed. The event allows you to handle this manually. Please note that this will not work for this case and you should always make sure that the user can add a proper values.
