Infragistics V9.2

The best way to get a grip of this bug? Is propably to set a test application, se code below....

When done, try this:

- Filter custID:s by enter "1" in the filer cell

- Use the backspace key to delete the "1"

- Position the cursor to fname filter cell, using the mouse

- RESULT : Error Messagebox: Error: Unable to update the data value:

============== CODE "INSTRUCTIONS"===========

1. Create a windows form application

2. Copy the code below into Form1

3. Add a load event on the form, se code below

4. Add an InitializeLayout to the grid, se code below
