I have a date field in a RadGrid called, "DueDate". I would like to make sure the user does not enter invalid data into the filter. To contemplate matters, this date field may not always be present. I may set the DueDate to an empty string in the grid ItemDataBound event depending on business rules. So, the Due Date in the grid may be a valid date or an empty string.
Does anyone know how I can check the filter after the user clicks a filterig menu option so I can throw an error before the grid tries to rebind the data?

Using this you can capture the filtering event and then either cancel it if you have a bad filter, or let it continue to execute the filtering:
| protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e) |
| { |
| if (e.CommandName == RadGrid.FilterCommandName) |
| { |
| if (logic) |
| { |
| e.Canceled = true; |
| } |
| } |
| } |
