I've created a custom implementation of SiteMapNode. I've attached it to Menu and it works ok. I've attached it to TreeView and it shows only nodes of one level. If I specify at SiteMapDataSource's ShowStartingNode==true, then I will see only root node and no expand buttons, if I specify ShowStartingNode==false, then I will see root's child nodes and no expand buttons also. What's wrong?

Periodically a rash of occurrences of the following error happen. I believe they're the result of hack attempts. Whether that's the case or not, my question is how can I handle the error? I want to avoid unhandled exceptions. The TreeView control is just a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.

I have a page that has a treeview and an Iframe. When I click a treeview entry, I display a gridview in the Iframe.

I can break in the LineItemDocs code behind, so it is getting to the page, but the LineItemDocs page does not render!The effect that I am going for is to click a treenode, display a page that has some functionality and contains a link. Click the link to display another page that contains additional functionality. Then be able to back-out to where I started. The treenode displays different gridviews (14 of them), depending on the node clicked.
I'm using Treeview control with asp.net 2.0. I would like to know how to get the client side events working. I don't want a post back for every little thing i do with the Treeview.

I have an ASP .Net TreeView control that I am dynamically adding tree nodes to from my codebehind on Page_PreRender. The TreeView is populated nicely and the appropriate checkboxes are where they are expected to be. For each of these nodes the SelectAction=TreeNodeSelectAction.None. However, when accessing the TreeView CheckedNodes() collection in my codebehind after selecting a few nodes (checkboxes are selected) and clicking a submit button to post back to the server in the button click event, my CheckedNodes.count() = 0. I can not figure out why my CheckedNodes collection in the codebehind does not contain the nodes that I have checked from the GUI.

public class MyTreeview : TreeView { protected override void TreeNode CreateNode() { return new MyTreeNode(); } } public class MyTreeNode: TreeNode { public MyTreeNode():base(){} }
I want to now use my inherited Node and TreeView in my .aspx file. I have the following directive, which is throwing an error -> File is in the special directory App_Code which is not allowed.
