    I have a treeview that is being used to display active and inactive data. By default the tree only shows active parents and their children but I have a check box on form that I am am wanting to use to force the update of the tree view with the reflected JSON data. I have verified that the JSON is updating the results buy reviewing my FIDDLER trace but for some reason the grid is not updating to reflect the change. I have search throughout the forum as well as the internet and can't seem to find an example close to what I am attempting to do. Any help would be appreciated. 

    I have included a sample of my code below:

    testHierarchy = getData();
                            dataSource: new{
    	                data: testHierarchy
      $("#includeInActive").live('click'function () {
                testHierarchy = [];

    To actually change the data used by the TreeView you should use the data method of the dataSource object of the TreeView.

    On a side note - to destroy the TreeView and re-create it I suggest you to use the destroy method to actually clear the data and event handlers used by jQuery.
