OpenRadWindow and load it's content

[Lorenzo]

Hi,
please bee good with me on this one, I'm sure the solution is stupid, but it is driving me crazy !
The problem is:
I have a Page with a RadWindowManager which contains a single RadWindow which contains ContentTemplate with some controls inside. In the same page I have a simple Link that triggers a javascript function that opens the window and triggers an ajaxrequest.

In the code behind of the page i get the ajaxrequest and I "should" do something on the controls inside the RadWindow.
The problem is that the RadWindow opens correctly, the ajaxrequest event gets raised correctly, but nothing happens on the controls inside the window !

Here is the code:
test.aspx
 

<%@ Page Title="" Language="VB" MasterPageFile="~/Resources/PAI_MasterPage.master" AutoEventWireup="false" CodeFile="test.aspx.vb" Inherits="test" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder_Body" Runat="Server">
<script language="javascript">
    function MyOpen() {

        var oWM = $find("<%=MyWM.ClientID%>");
        var oWin = oWM.open(null, 'W_PaiToolPackItem');
        var ajaxManager = $find("<%= M.ClientID %>");
        ajaxManager.ajaxRequest("IdCustomer");
    }
</script>
<telerik:RadAjaxManager runat="server" ID="M">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="B">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="P" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

<a href="javascript:MyOpen();">Open</a>

<telerik:RadWindowManager runat="server" ID="MyWM" Enabled="True">
<Windows>
    <telerik:RadWindow runat="server" ID="W_PaiToolPackItem">
        <ContentTemplate>

                <asp:Button runat="server" ID="B" Text="Bottone" />

                <asp:Panel runat="server" ID="P">

                    <asp:Label runat="server" ID="L"></asp:Label>

                </asp:Panel>

        </ContentTemplate>

    </telerik:RadWindow>
</Windows>

</telerik:RadWindowManager>

</asp:Content>

here is the code behind:
test.aspx.vb

Partial Class test
    Inherits System.Web.UI.Page


    Protected Sub M_AjaxRequest(ByVal sender As Object, ByVal e As Telerik.Web.UI.AjaxRequestEventArgs) Handles M.AjaxRequest
        L.Text = "Ajax Load"

    End Sub

End Class

The action to perform is stupid, but it does not happen !
If I click onto the button (and a postback starts) the Label loads !

Please help

Thank you

Lorenzo

Hi,

Please add the following Ajax setting in order to have the label load properly on AjaxRequest:

<telerik:AjaxSetting AjaxControlID="M">
           <UpdatedControls>
               <telerik:AjaxUpdatedControl ControlID="P" />
           </UpdatedControls>
</telerik:AjaxSetting>

I hope this helps.

Sincerely yours,

Hi,
your suggestion seems to solve my problem, but now I have a new one !
In the page I put a label and would like that pressing the button inside the RadWindow a certain text gets loaded into the label.

I attach code

<%@ Page Title="" Language="VB" MasterPageFile="~/Resources/PAI_MasterPage.master" AutoEventWireup="false" CodeFile="test.aspx.vb" Inherits="test" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder_Body" Runat="Server">
<script language="javascript" type="text/javascript">
    function MyOpen() {

        var oWM = $find("<%=MyWM.ClientID%>");
        var oWin = oWM.open(null, 'W_PaiToolPackItem');
        var ajaxManager = $find("<%= M.ClientID %>");
        ajaxManager.ajaxRequest("IdCustomer");
    }
</script>

<telerik:RadAjaxManager runat="server" ID="M">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="M">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="P" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="B">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="LL" />
                <telerik:AjaxUpdatedControl ControlID="P" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

<a href="javascript:MyOpen();">Open</a>
<br /><br />

<asp:Label runat="server" ID="LL"></asp:Label>

<telerik:RadWindowManager runat="server" ID="MyWM" Enabled="True">
<Windows>
    <telerik:RadWindow runat="server" ID="W_PaiToolPackItem">
        <ContentTemplate>

                <asp:Button runat="server" ID="B" Text="Bottone" />

                <asp:Panel runat="server" ID="P">

                    <asp:Label runat="server" ID="L"></asp:Label>

                </asp:Panel>

        </ContentTemplate>

    </telerik:RadWindow>
</Windows>

</telerik:RadWindowManager>

</asp:Content>

While in the code behind I have

Partial Class test
    Inherits System.Web.UI.Page


    Protected Sub M_AjaxRequest(ByVal sender As Object, ByVal e As Telerik.Web.UI.AjaxRequestEventArgs) Handles M.AjaxRequest
        L.Text = e.Argument
    End Sub

    Protected Sub B_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles B.Click
        L.Text = "PostBack"
        LL.Text = "Button clicked"
    End Sub
End Class

Now the page throws, while loading the obnoxious error:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>). 

What's wrong !??

Thanks again

Lorenzo

Hello Lorenzo,

I would suggest you to wrap the JS code into RadCodeBlock control. See this article for more information on this.
