How can I modify the default filter operator on DevExpress.Xtragrid.gridcontrol and add a new value there with what is already there.
Simple I want to add "Greater than > 0" to a numeric value column, keeping what it is already there.
Check out this link, it helps. http://documentation.devexpress.com/#windowsforms/CustomDocument2567
gridView1.ActiveFilterString = "[YOURCOLUMN] > 0";
