ajax problem with Tree in UserControl

[Jean-Marc]

Hi,
I have an ascx that basiocally is just a tree.
this ascx is included on aspx file.
by clicking a button I want to change the tree datasource.
i see difference using ajaxmanager and triggers. First does not work the second does.
Unfortunally i need the first case

Here is a sample
(ajax)

<%@ Register TagPrefix="qsf" TagName="RTV" Src="~/Admin/CategoriesManagement/TreeCategories.ascx" %>

.....
    <form id="form1" runat="server">
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
    </telerik:RadScriptManager>

   <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        <AjaxSettings>
           <telerik:AjaxSetting AjaxControlID="Button1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="CatTree1" />
            </UpdatedControls>
           </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

     <table style="width: 100%; text-align: left; background-color:#2e2e2e;" cellspacing="0" cellpadding="0">
        <tr>
            <td>
                <qsf:rtv runat="server" ID="CatTree1" ></qsf:rtv>
            </td>
        </tr>
    </table>

    <asp:Button ID="Button1" runat="server" Text="Button" Width="500px" />

    </form>
...

code

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
           'change its datasource
            CatTree1.setInitialPath(PathOfThreeCategory)
 End Sub

second case (triggers)

<table style="width: 100%; text-align: left; background-color:#2e2e2e;" cellspacing="0" cellpadding="0">
    <tr>
        <td>
                <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
                </telerik:RadScriptManager>

            <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
                    <ContentTemplate>
                            <qsf:rtv runat="server" ID="CatTree1" ></qsf:rtv>
                    </ContentTemplate>

                    <Triggers>
                        <asp:AsyncPostBackTrigger ControlID="Button1" />
                    </Triggers>
                </asp:UpdatePanel>

        </td>
    </tr>
</table>


<asp:Button ID="Button1" runat="server" Text="Button" Width="500px" />

same code behind..

Please May you tell me where i'm going wrong? Thank you

I dug in it.

It tuned out that my problem is tht the tree control is inside un updatepanel

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

                                    <ContentTemplate>

                                            <telerik:RadTreeView    ID="RTV_Categories"                                                   

                                                Runat="server"

                                                >

                                            </telerik:RadTreeView>

                                    </ContentTemplate>

                                             

                                    <Triggers>

                                        <asp:AsyncPostBackTrigger ControlID="IB_AddNode" />

                                    </Triggers>

 

                                    <Triggers>

                                        <asp:AsyncPostBackTrigger ControlID="IB_DelNode" />

                                    </Triggers>

                                </asp:UpdatePanel>

 

so, is there a way to keep in the ascx the triggering on addnode and denNode controls and making ajax work?
Thank you

Hello Jean-Marc,

In general when using web user controls it is strongly recommended that you use the RadAjaxManagerProxy control instead of the RadAjaxManager control as explained here. Please take a look at our on-line demos as well for a better understanding of its application.
