int col = this.gridDataBoundGrid1.Binder.NameToColIndex("CustomerID"); this.gridDataBoundGrid1[1, col].Text = "ANTON"; this.theFilterBar.RowFilter = "[CustomerID] = 'ANTON'";2) I am not sure I understand. The custom dialog is displayed in a CurrentCellAcceptedChanges event handler. In this same handler, the RowFilter property is set with the string returned by the dialog. Setting this RowFilter property is what sets the DataView.RowFilter which is what changes the display. The LIKE is recognized and used in the DataView.RowFilter property.
