I have a TreeView menu populated from a SiteMapDataSource. The TreeView defaults to all nodes expanded, but the normal client side expand/collapse behaviour for the nodes is not working. I get one Javascript error in my Firebug console, being:
TreeView_ToggleNode is not defined
What could be causing this?

I've got a CollapsiblePanelExtender in place on a panel in test and it works like a champ. (I get excited about the simplest things). When I click the panel header it expands and collapses with smooth animation, as expected and desired.
But when I change its state via code behind, it seems I am merely changing its state and somehow bypassing the javascript that controls the smooth animation.
My markup is out of the box. I have added code behind and some javascript, but I am missing the connection. Here is the javascript:
function pageLoad(sender, args)
{
smoothAnimation();[code]....
And here is the code behind:
protected void btnExpand_Click(object sender, EventArgs e)
{
this.CollapsiblePanelExtender1.Collapsed = false;[code]....
I have a code that load hierarchy( nodes) into trew view.. by selecting different date, the hierarchy result from SP will show in the treeview..
the problem is even though I select a different date.. the result( node) of previous date is still showing in addition to the new hierarchy result...
it;s like the new result node is appended to existing node.. instead of refreshing the node and showing only the new result. How can I clear out the treeview nodes before adding new nodes from different date?
how can add , edit, delete nodes and sub nodes in treeview in vb.net 2005 and sql server2005

View 1 RepliesI having an issue with the ASP.NET Treeview control. I create the treeview just fine but the nodes will not expand or collapse. I see there is a javascript error but it is for line 1 character 0 of the webpage, there is nothing at line 1 character 0.
I am using the ASP:Treeview control in conjunction with the Telerik controls, but I'm not sure if that is an issue.
I saw there was a similar question here but the answer is not pertinent to my site. Has anyone run into this issue before? I've tried searching Google and tried a number of proposed solutions but so far none have worked.

i have a databound treeview in asp.net. how can i expand the root node and have the rest of the tree nodes all colapsed?
View 1 RepliesShould be easy but I cannot find a property which allows me to right align the nodes in a treeview.
I've tried adding text-align: right in a CSS declaration linked from NodeStyle > CssClass. Nothing.
I understand that a treeview cannot expand/collapse without javascript. But is it possible to open the treeview in expanded form when javascript is disabled? Even if I cannot expand/collapse the nodes, at least I can click on the nodes that will display the data related to that node.
Similar to the treeview used in online auction sites, our treeview looks something like this: [URL], where clicking on a link will redirect me, and clicking on the "+" will expand or collapse the node. The only difference would be that ours is databound.
Another developer is working on this and he tells me that this is not possible without javascript. This webform in particular works almost entirely without javascript, and I'd like the treeview to also work partially.
I see that the data is there when I autogenerate. I can't seem to understand how to get the values from the nodes? Any reference anywhere on the ways to set the properties of databandings/TreeNodeBinding?
Like I need the name inside here
<TaxonomyName>Resource Enhancement</TaxonomyName>
Using
<asp:TreeView ID="tvSubmissionCategories" runat="server" DataSourceID="xdsSubmissionCategories"
AutoGenerateDataBindings="False">
<DataBindings>
<asp:TreeNodeBinding DataMember="Taxonomy" Text="TextThing" />
</DataBindings>
</asp:TreeView>
Second: Is there a way to select more than one node in tree view (like we do in Windows Explorer, by pressing SHIFT or CTRL) ?
View 2 RepliesIn my asp.net application I'm using TreeView control, and at some point I noticed that TreeView.Nodes property doesn't return all the nodes, so I'm curious how can I get ALL Nodes of TreeView control to iterate through them in foreach loop, any tricks, or I miss something?
View 6 RepliesAny limit to the number of nodes you can have in a treeview, I have been having some problems getting it to display with the panel I made. I have actually decided not to use the treeview, in fact may drop this part of the app altogether, but just wondering for future reference. I know if certain browsers have a limit for the the url, but can not seem to find anything, if there is anything, on a node limit. I am using asp.net 3.5 with VB and my browser is IE8, well the only one I tested on.

I using TreeView with ShowCheckBoxes="All" in an ASP.NET 3.5 web application and for some reason the checked nodes are not returned in order. Lets say I have nodes A,B,C and I select B and C and hit the save button and when I check the CheckedNodes property of the Treeview the checked nodes are in order (B,C). But the next time when I go back to the page and select the node A the order is being returned B,C,A. What could be the reason for this behavior?

View 1 RepliesThe following is a version of some code I'm having trouble running in IE version 6. It seems to work fine in IE 7, IE 8, FireFox, and Google Chrome. But in IE 6, when I expand and collapse nodes in the treeview, the SurroundingWrapper div resizes, but the message at the bottom stays glued in place (I'd prefer it stayed glued to the bottom of the div SurroundingWrapper). Can someone please tell my why this code falls apart in IE 6?
