Hello Dognail,

In order to change the default value of the custom filter dialog, I would recommend handling the BeforeCustomRowFiltersDialog event of the UltraGrid. The event arguments can get you the UltraGrid used for these filter operators and operands by using the e.CustomRowFiltersDialog.Grid property, where ‘e’ is the event arguments.

From here, you can index into the UltraGrid.Rows collection and set the value of the second cell to your desired value. In this case, the code for this would look like the following:

//In the BeforeCustomRowFilterDialog event…
UltraGrid grid = e.CustomRowFiltersDialog.Grid;
grid.Rows[0].Cells[1].Value = “(Blanks)”;

I have attached a sample project that demonstrates the above. I hope this helps.

Please let me know if you have any other questions or concerns on this matter.
