Property Value

|---|---|
| ExceptionMode | A ExceptionMode enumeration value specifying the response type. |
Available values:
| Name | Description |
|---|---|
| DisplayError | A control displays a tooltip or message box with an error description specified by the ExceptionEventArgs.ErrorText property. A tooltip is displayed for invalid cells. A message box is displayed for invalid rows (records). |
| ThrowException | A control throws an exception specified by the ExceptionEventArgs.Exception property. |
| NoAction | A control suppresses an error message box/tooltip and exceptions. Values remain unchanged. |
| Ignore | Discards new data and reverts to an old value. Note In standalone editors, because of the .NET binding mechanism, the Ignore value doesn’t work correctly. In container controls, the Ignore value works as expected. |
Remarks
Use the ExceptionMode property to specify the action performed in response to entering an invalid value. You can display a message box/tooltip with a specific error description, suppress any action, throw an exception or discard new data and revert to an old value.
