Hi,

I would recommend doing this via LoadOnDemand as you can then decide on each level of the tree what data to load depending on the selected node. This way you don't have to have all levels and info in one big Recordset or XML. See my thread with the viewstate which includes all of the code you need.

Hope this helps.

This is the thread:

http://www.intersoftpt.com/Community/WebTreeView/TreeView-not-keeping-Viewstate/

Unfortunately, our WebTreeView only can be binded by using XMLDataSource or SiteMapDataSource.

If you would like to use with database, you can try our WebGrid SelfReference scenario.

I have just found some way how to populate database via dataset. By populate database in each nodes, it would be similar with WebTreeView unbound. Attached sample is my sample. Hope this helps you.

I can't download the sample!

Please re-try again. I have re-uploaded it.

thank you handy..

the tree is working for me... but i have some small problem...

if i give the image for the tree node, it working but the expand image property is not working

here is the code below

 protected override void OnInitComplete(EventArgs e)

    {

        base.OnInitComplete(e);

        WebTreeViewNode rootNode = new WebTreeViewNode();

        rootNode.Name = "REPORTS";

        rootNode.Text = "REPORTS";

        rootNode.Image = "~/images/folder-close.jpg";

        rootNode.ExpandedImage = "images/folder-open.jpg"; // This is not working

        rootNode.Value = "report";

        WebTreeView1.Nodes.Add(rootNode);

        WebTreeView1.EnableLoadOnDemand = true;

        WebTreeView1.AllowNodeEditing = AllowEditing.Yes;

        WebTreeView1.AutoPostBackSettings.OnNodeEdit = true;

    }

I have tested and it is a minor bug in our WebTreeView. I have forwarded this to our developer with #406 WI number and they will fix it in our next release.

hi,

ok.

also i have tried some button event to catch the selected node. But it seems not working.

below is the code,  i have used.

 protected void Button1_Click(object sender, EventArgs e)

    {

          Label1.Text = WebTreeView1.SelectedNode.ToString();

    }

   His example, the database is good, but I have a problem with the options to add, edit, delete, change levels and other events of the treeview.  please send me an example with these events

It would be good to publish a couple of examples based on database that is helpful not only work with XML files is very static .

please help me

Thank you for your feedback. Unfortunately, even though it is populated from database, it is assigned into each node one by one. This behavior is unbound behavior. So, you could not add, edit and delete on WebTreeView.
