Treeview in asp.net 2.0

[tmldias]

Hi all,

I've already "lost" too many time and no success...

I want to remove the default postback when the user presses a node in
the tree. I want to navigate and selecte nodes in the tree just
client-side without postbacks to the server.

Thanks.

Greetings,

after you downlaod the atals framework u can simply add this part of
code in your aspx page in your "VS Atlas project" just right after the
script manager code



<atlas:UpdatePanel ID="up1" runat="server">
<ContentTemplate>
<atlas:UpdateProgress ID="process1" runat="server">
<ProgressTemplate>
// Code for your TreeView goes here

</ProgressTemplate>
</atlas:UpdateProgress>
</Content Templat>
</Atlas:updatepanel>


its tht simple, happy coding

i was about to forget to refer to the updateprogress control in the
atlas framework i think u gonna like this so let me add this 2 lines of
code.

<atlas:ScriptManager ID="sm1" runat="server"
EnablePartialRendering="true"></atlas:ScriptManager>
<atlas:UpdatePanel ID="up1" runat="server">
<ContentTemplate>


<atlas:UpdateProgress ID="process1" runat="server">
<ProgressTemplate>
<div class="title" style="font-weight: bold;
vertical-align: middle; text-transform: capitalize;
color: #cc6600; font-family: 'Arial Narrow', 'Arial
Black'; letter-spacing: 10px;
text-align: center">
<img alt="" src="../loading.gif" style="width: 55px;
height: 55px" /><br />
<br />
Loading</div>
</ProgressTemplate>
</atlas:UpdateProgress>



</ContentTemplate>
</atlas:UpdatePanel>

Hi,

About populating without postback

About playing with SelectAction
http://aspadvice.com/blogs/joteke/archive/2006/08/19/20948.aspx

About modifying selection, you set node's SelectAction. Just note that
TreeView's nodes work in two mutually exclusive mode, selection mode or
navigation mode. Node is in navigation mode, if it has NavigateUrl
specified. And it's in selection mode when NavigateUrl equals to empty
string. In selection mode you can control how it works, via the SelectAction
property.

And yes, for selection to work 100% on client, you need Atlas.
