    I have implemented loadondemand for my radtreelistview

    when the control is loaded,
    the filter on one of the colums is only displaying data members that exists in the first level items
    this is fine,
    but I would expect when I expand some rows,
    and open the filter panel again, the data members exist in child rows should also be availible in the filter panel

    however, typing the child level data member in the text boxes and apply filter works
    is there any way to regenerate the list in the filter panel?

    in addition, when I have null values in the column, the apply filter takes forever to complete, the application just hang

    I want to explain a bit of what I need to achieve with radtreelistview below,
    so I can get some help and to see whether I can achieving the goals better with radtreelistview

    What am I trying to do here is the following:

    1. a three level radtreelistview, each level is a different type
    2. each type will have different attributes or properties specific for them
    3. since radtreelistview will have different levels to share the same columns, we decided to combine those attributes and set them to be editable only when applicable
    4. some of the columns will be combobox columns, however, I don't want the user to select from a combo box when they are on a row that they shouldn't select one for that attribute
    5. so I have set cell templates for those columns, in the cell template I have put in just a combo box, and has its Visibility binded to view model object
    6. then the user can only select whenever applicable
    7. now when i want to filter them, i can only use the numbers (the data memebers or value memebers) but not text (display memeber), do I need to create an attribute in the view model and fill in the value (text) depends on the view model's data or value memeber? or is there an easier way of doing it?
