Remarks

The ASPxFilterControl isn’t designed to operate with the bound source control. To enable end-users to construct filter criteria, you should manually create filter columns and add them to the ASPxFilterControl.Columns collection. The ASPxFilterControl provides eight column types (text, spin, combo box columns, etc.).

The example below demonstrates how to create a filter column in code:

private void CreateSpinEditColumn(ASPxFilterControl filterControl, string propertyName, 
        string displayName) {
    FilterControlSpinEditColumn filterColumn = new FilterControlSpinEditColumn();
    filterColumn.PropertyName = propertyName;
    filterColumn.DisplayName = displayName;
    filterControl.Columns.Add(filterColumn);
}
