    [CLOSED] TreePanel Issue

    Hi,
    How to deal with the following issue, when there is no child node and the TreePanel RootVisible property is set to false, we are getting the request failure error message.

    Hi,

    Please set up
    <Store>
        <ext:TreeStore runat="server" AutoLoad="false" />
    </Store>
    for the TreePanel.
