Using SetPropertyValueCommand

[David]

I am trying to add checkboxes to a RadTreeView, but I only want the checkboxes to be on one level of the tree.  I have discovered that to do this, I need to turn on checkboxes for the entire tree, and then suppress them where I don't want them.  As far as I can tell, using the SetPropertyValueCommand in an Execute would do this, but I haven't been able to find any code showing how this would be done.  I need to know how to specify which property is being changed, and how to specify that value.

Otherwise, if there is a better way to accomplish the task, I would appreciate hearing the solution.  Any advice would be appreciated.

Hello David, 

Thank you for writing.

RadTreeNode has a ShowCheckBox property which you can use to explicitly hide the check box. You can write a recursive method that hides all check boxes on particular levels. For example:
 

RadTreeView treeView = new RadTreeView();
int[] levels = new int[] { 1, 5, 7 };

private void HideCheckBoxes(RadTreeNodeCollection nodes)
{
    foreach(RadTreeNode n in nodes)
    {
        if (levels.Contains(n.Level))
        {
            n.ShowCheckBox = false;
        }

        this.HideCheckBoxes(n.Nodes);
    }
}

 
The function is invoked like this:
 

this.HideCheckBoxes(this.treeView.Nodes);

 
Write again if you have other questions.

The problem is, the node.ShowCheckBox = false statement does not always work, as noted in the other thread with that title.  It certainly didn't work on the highest level of the tree.
