CurrentFilterValue in google-like filtering not working

[Carlos]

Hi I am testing the google-like example but encounter  a problem when asking for the CurrentFilterValue, here is the code,

protected void RadGrid_ItemCommand(object source, GridCommandEventArgs e)
        {
            if ((e.CommandName == "Filter"))
            {
                string something = "";
                foreach (GridColumn column in e.Item.OwnerTableView.Columns)
                {
                    something = column.CurrentFilterValue;
                    column.CurrentFilterValue = string.Empty;
                    column.CurrentFilterFunction = GridKnownFunction.NoFilter;
                }
            }
        }

The issue is that the string something is always “” for all the values. I test the same code with a default GridColumn and it works fine (change the value of “something”) but not with the current google-like filtering example.

The code in the CustomeFilter is the same as the demo code(MyCustomFilteringColumnCS.cs).

Thanks
