I noticed a bug with the RadTreeView; configuration below. When all items are disabled, if you then focus the RadTreeView and then press Enter, it will throw an error of "Line: 8887 Error: Unable to get property 'set_selected' of undefined or null reference" in Telerik.Web.UI.WebResource.axd.

It appears to be trying to set selected but since all items are disabled, this error is I tried to put the OnClientKeyPressing to a javascript function that is just { return false;} but that does not stop the error from occurring.

How can I get around/suppress this error?

<telerik:RadTreeView ID="foo" runat="server" CheckBoxes="False" CheckChildNodes="False" MultipleSelect="True"
    ShowLineImages="True" EnableDragAndDrop="False" BorderColor="#336699" BorderStyle="Solid" BorderWidth="1px"
    height="410px">
</telerik:RadTreeView>

Hi,

Could you specify the version of the controls that you are using, as well as the browser where this problem is reproduced?
