DataItem is null

[stephen cossgrove]

Hi, Here is my setup:
1. in the file

<

 

telerik:radtreeview id="RadTreeView2" runat="server" width="100%" height="100%"

 

 

datasourceid="ObjectDataSource1" datafieldid="ID" datafieldparentid="ParentID"

 

 

datatextfield="Text" OnNodeClick="RadTreeView2_OnNodeClick">

 

 

<DataBindings>

 

 

<telerik:RadTreeNodeBinding Expanded="true" />

 

 

</DataBindings>

 

</

 

telerik:radtreeview>

 

<

 

asp:ObjectDataSource ID="ObjectDataSource1" runat="server"

 

 

TypeName="xxxx.Component.Classes.SiteDataItemCache" SelectMethod="GetSiteDataItems">

 

</

 

asp:ObjectDataSource>
2. in the codebehind

 

protected

 

void RadTreeView2_OnNodeClick(object sender, RadTreeNodeEventArgs e)

 

{

 

SiteDataItem item = (SiteDataItem) e.Node.DataItem;

 

}

3. THE PROBLEM
the e.node.DataItem is always null.
Can anyone tell me why and how i can make this the SiteDateItem that is bound to the tree node?

Hi,

this article should be of help:

OK, so  how do i get the object that is being bound on say the nodeclick event?

How do i get the id of the clicked node and it's parent node id?

Hello stephen,

You should subscribe to OnNodeDataBound event and set the needed values as custom attributes of the nodes of the treeview, then you can get them without a problem in NodeClick event handler.

Kind regards,
