Problem in Custom Attributes

[Eng.Bassel Samman]

Dear,
I add new custom attribute to RadTreeNode using the following code:

Nod.Attributes.Add("Key", "Value")
Where Nod is a RadTreeNode, the attributes is added (Node attributes count is increased) but when I retrieved its value using: Nod.Attributes(Key) I always got Nothing.
Best Regards

Hello,

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);
}

Check with the example and see what you are missing in your code.
