Rad tree view :Binding custom attributes

[piyush]

I have following columns in my datasource which is a Generic list

Element ID
ParentElementID
Element Name
Sequence
Layer

I need to create and bind  custom attributes like Layer,Sequence,etc from the datasource so that I can manipulate them at Nodedatabound event .
Also for several childs of parent node
I need to order the sequence of nodes on the basis of Sequence .

Hi Piyush,

Checkout the following example which shows how to add custom attributes in NodeDataBound event.

ASPX:

<telerik:RadTreeView ID="RadTreeView2" runat="server" DataFieldID="CategoryID" DataSourceID="SqlDataSource1"
    DataTextField="CategoryID" OnNodeDataBound="RadTreeView2_NodeDataBound" OnNodeClick="RadTreeView2_NodeClick">
</telerik:RadTreeView>

C#:

protected void RadTreeView2_NodeDataBound(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e)
{
    DataRowView dataSourceRow = (DataRowView)e.Node.DataItem;
    //set custom attributes from the datasource:
    e.Node.Attributes["CategoryName"] = dataSourceRow["CategoryName"].ToString();
}
protected void RadTreeView2_NodeClick(object sender, RadTreeNodeEventArgs e)
{
    String Name = e.Node.Text.ToString();
    String CategoryName = RadTreeView2.SelectedNode.Attributes["CategoryName"];
    Response.Write("You have selected " + Name + " with Name " + CategoryName);
}
