Treeview in asp 2.0 problem

[Ruszt]

hello,
i've placed the code below in onLoad event of my page, which should fill in
Treeview control called TreeViewCategories with nodes from XmlDataSource

XmlDataSource xds = new XmlDataSource();
xds.Data = xmlCategories.GetAllCategories().InnerXml;
this.TreeViewCategories.DataSource = xds;
this.TreeViewCategories.DataBind();

but sth strange happens to it...
the content of treeview control stays the same even if xds contains new data
(i've checked it with debugger) the only solution i've found is to rebuild
all the website

another code:
this.Label1.Text = DateTime.Now.ToString("G");

works fine and label changes its value everytime I recall the page

any advices?

(sorry for my English)

is it the line: this.Label1.Text = DateTime.Now.ToString("G");
after or before your treeview code?

label code is after the treeview code in the same event - onLoad

I guess you can try something like:
this.TreeView1.Nodes.Clear();
and then try and repopulate the tree and see what happens...
