I have a page with a usercontrol. The usercontrol contains a RadPanelBar, and within this I have a ItemTemplate with a RadTreeView. I need  to do DragAndDrop a HTML element on my page. I put the user control within a radAjaxPanel to ajaxify, but it's do always full postback when using DragAndDrop.
This is the code.

<radA:RadAjaxPanel ID="RadAjaxPanel1" runat="server">
    <telerik:RadPanelBar ID="RadPanelBar1" runat="server" Width="100%" Skin="WebBlue">
        <CollapseAnimation Duration="100" Type="None" />
        <Items>
            <telerik:RadPanelItem Expanded="True" Text="Templates List">
                <Items>
                    <telerik:RadPanelItem >
                        <ItemTemplate>
                             
                             
                                <div class="ff" style="padding: 2px 2px 2px 2px">
                                    Show templates below:</div>
                                <div class="ff" style="padding: 2px 2px 2px 2px">
                                    <asp:DropDownList ID="ddlType" runat="server" class="ff" Width="98%" AutoPostBack="true"
                                        OnSelectedIndexChanged="ddlType_SelectedIndexChanged">
                                        <asp:ListItem Value="0">Product</asp:ListItem>
                                        <asp:ListItem Selected="True" Value="1">Structural</asp:ListItem>
                                    </asp:DropDownList>
                                </div>
                                <div id="divProductsToShow" runat="server" class="ff">
                                    <span>
                                        <asp:LinkButton ID="lnkShowRelated" runat="server" Enabled="true" OnClick="lnkShowRelated_Click">Show related</asp:LinkButton>
                                        /
                                        <asp:LinkButton ID="lnkShowAll" runat="server" Enabled="false" Font-Bold="true" OnClick="lnkShowAll_Click">Show all</asp:LinkButton>
                                    </span>
                                </div>
                                <div class="ff" style="padding: 2px 2px 2px 2px">
                                     <radA:RadAjaxPanel ID="RadAjaxPanel8" runat="server">
                                    <telerik:RadTreeView ID="RadTreeView1" runat="server"  EnableDragAndDrop="true" OnNodeDrop="RadTreeView1_NodeDrop" >
                                    </telerik:RadTreeView>

                                </div>
                        
                        </ItemTemplate>
                    </telerik:RadPanelItem>
                </Items>
            </telerik:RadPanelItem>
            <telerik:RadPanelItem Expanded="True" Width="100%" Text="Most Used Templates">
                <Items>
                    <telerik:RadPanelItem>
                        <ItemTemplate>

Hi again,
I thought the problem was that the RadTreeview was inside a RadPanelBar in a user control, but put one on my page RadTreeView (inside a RadAjaxPanel) and I still have the same problem.

 I do not understand what happens. Why is the full postback?

Hi Pablo,

Could you please let me know what the result is if regular asp UpdatePanel is used instead of RadAjax?

The result is the same. i Already tried a RadAjaxManager, RadAjaxPanel, UpdatePanel asp (Conditional). A couple of days ago I had this problem

http://www.telerik.com/community/forums/aspnet-ajax/ajax/radpanelbar-how-to-unselect-item.aspx

If I use the Net2 RadAjaxPanel my user control if it works, but if I DragAndDrop not work.


I think this is also causing this new problem. It's something in my application, because I made a new application with a similar scenario and there is no problem.
