Hi,

I want to set the selected node in my treeview by the programm. I tried the following:

testTree.SetSelected(testTree.Selected);

So just select the selected Node again to invoke the function private void Tree_NodeClick(object sender, TreeEventArgs e)

But I get the error: Message: Unhandled Error in Silverlight 2 Application Object reference not set to an instance of an object.   at SLApp2.MainPage.Tree_NodeClick(Object sender, TreeEventArgs e)   at Liquid.Tree.RaiseEvent(TreeEventHandler handler, Object sender, TreeEventArgs args)   at Liquid.Tree.set_Selected(Node value)   at Liquid.Tree.SetSelected(Node node)

Anbody an idea how to just invoke the Tree_NodeClick function again for the selected node?

Hi Bilik,

You could try setting Selected = null before your call to SetSelected this should then raise the NodeClick event.

Thanks!

Hi dan,

I tried the following:

Node selected = ProductTree.Selected;

ProductTree.Selected = null;

ProductTree.SetSelected(selected);

But I get the same error message as above. It seems that the Tree_NodeClick function does not get the parameters it needs.
