    Hello!

    I am implementing a TreeList with 2 columns. One is a name and the other one is a SelectColum, with checkboxes. 

    This list displays a hierarchy. 

    Is that possible to have tri-state checkbox behaviour for the SelectColumn?


    Any help will be much appreciated.


    Thanks,
    Christian

    Any comments with this?

    I guess it is an easy question.

    Thanks,
    Christian.

    Hi Christian,

    You cannot get such behavior with a TreeListSelectColumn but you could declare a TreeListTemplateColumn with a tri-state RadButton (there is a CheckBox with three states in the sample) inside and handle its state changes manually.
