Treeview & UpdatePanel - Assertion failed - cant find last / in base url

Hi,

I am using a TreeView and couple of server controls. The treeview children are dynamically added on click of a node. I have the treeview control inside an update panel. Everything works if I access the page in a normal IE window. When I try to access the same page through a modal dialog, during postback, it opens a new window. To avoid that, I've added<base target = "_self" />.

Now I'm getting another error with Atlas. On click of tree node, it says "Assertion Failed : Can't find last / in base url. If I remove the <base..> it doesn't work.

Looking for an immediate solution. I've spent almost a day in googling. But no luck yet.

Many Thanks,
Mani.

hello.

you can also try using an iframe inside your popup page (ie, put only an iframe inside your popoup window which loads the page that shows the content)...maybe it'll solve that problem.

Mani,

Add:<basetarget="_self"href="http://localhost/***/***/"runat="server"/>

because our dear js function check if u have base tag , then try to concat with href value. in your case you don't have it.

what if i'm using a Master Page - i can't hard code a path in the href. Is there any way to accomplish this? Plus - even if i hard code, the paging on my grid view does not work now.

Try this, without hard code url

 <base target="_self" href="<%=Request.Url.OriginalString%>" />

works perfect ... Thanks.

treeview inside of updatepanel = Validation of viewstate MAC failed

i have some nodes added to my treeview inside of an updatepanel and it seems to give me "

Validation of viewstate MAC failed" error each tme i click a node twice.

Nothing happens on the first time i click a node

is there some tutorial or standard thing to do with a treeview in an update panel?

It sounds very strange about asp:TreeView and asp:UpdatePanel from your description.Can you post some codes here? I'd like to test it.
I tested asp:UpdatePanel working with asp:TreeView in Ajax RC 1.0 and found it worked.
Here are my testing codes for your reference.
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:TreeView ID="tv" runat="server" OnSelectedNodeChanged="tv_SelectedNodeChanged">
<Nodes>
<asp:TreeNode Text="File" Value="File"></asp:TreeNode>
<asp:TreeNode Text="Edit" Value="Edit"></asp:TreeNode>
<asp:TreeNode Text="View" Value="View"></asp:TreeNode>
</Nodes>
</asp:TreeView>
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdateProgress ID="UpdateProgress2" runat="server"
AssociatedUpdatePanelID="UpdatePanel1"
DisplayAfter="2000"
DynamicLayout="False">
<ProgressTemplate>
UpdatePanel1 is updating now!
<input type="button" id="AbortCallbackButton" value="Abort" onclick="AbortCallback()" />
</ProgressTemplate>
</asp:UpdateProgress>
<br />
This is text after the UpdatePanel and UpdateProgress controls.
<script type="text/javascript">
function AbortCallback()
{
Sys.WebForms.PageRequestManager.getInstance().abortPostBack();
}
</script>
Behind Codes:
protected void tv_SelectedNodeChanged(object sender, EventArgs e)
{
System.Threading.Thread.Sleep(10000);
}
Wish this can help you.
