I was trying to implement the code from the following article
I'm using the server side approach, but i have a problem.
If i expand a parent that has childs and the parent was checked,
When i debug the NodeExpand event handler i see that the e.Node.Checked
property of the parent node is always false.
Only if i checked the root parent of the tree i get the desirable result according to my action, the other sub-parents doesn't get it.
protected void RadTreeView1_NodeExpand(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e)
RadTreeNode firstChild = new RadTreeNode("new child1", "new1");
firstChild.Checked = e.Node.Checked; //e.Node.Checked is always false!
In other words: I don't get any indication that the parent node is checked.(gets always false).
I tried with tristate mode and without tristate mode. and the CheckChildsNodes property is true.
i use version: 2010.3.1109.35
