Hey

I have 3 pages(masterpage, listTask, editTask)
masterpage
- listTask
- editTask

When i click a task in listTask.aspx, editTask.aspx open in a radWindow.
I would like top open a new radwindow from inside the opened radwindow(editTask), but i don't want the new window to appear inside the allready opened window.

Now i have the radWindowManager in the masterpage, and i can access this from the contentpage. But i can not access this windowmanager from the open window.

Hope someone can help me with this problem

I have the same problem. Following the article in http://www.telerik.com/help/aspnet-ajax/window_programmingopeningfromwithin.html did not help. The radwindow did not "recgonise" the radwindow manager in the master page.

Hi,

I tried your demo, it works. But in my case, it doesn't.

My original javascript:

    function showMessageWindow() {
     // open the default error radwindow
     var oBrowserWnd = GetRadWindow().BrowserWindow;
     var w = oBrowserWnd.radopen('/Common/RadWindows/MessageWindow.aspx', 'rwMessageWindow');
     w.setSize(400, 300);
    }

The above works.

If i change as follows:

    function showMessageWindow() {
     // open the default error radwindow
     var parentWindow = GetRadWindow().get_windowManager();
     var oWindow = parentWindow.open('/common/RadWindows/MessageWindow.aspx', 'rwMessageWindow');
     oWindow.setSize(400, 300);
    }

It doesn't work, with the following error:

I have created the similar pages:

1) MasterPage:

    
            <%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="Test_MasterPage" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml">  
        
            <head runat="server">

            <body> 
        
                <form id="form1" runat="server">

                        <telerik:RadWindowManager ID="RadWindowManager1" runat="server">  
        
                        </telerik:RadWindowManager> 
        
                        <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">

                </form> 
        
            </body> 
        
            </html>

2) Default.aspx

    
            <%@ Page Title="" Language="VB" MasterPageFile="~/Test/MasterPage.master" 
        
                AutoEventWireup="false" CodeFile="default.aspx.vb" Inherits="Test_default" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">

            <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">  
        
                <script type="text/javascript">  
        
                    function openRadWindow() {  
        
                        var oWindow = radopen('http://www.google.com', 'abc');  
        
                        oWindow.setSize(500, 500);  
        
                        oWindow.center;  
        
                    }  
        
                </script> 
        
                <h5> 
        
                    here the content page</h5> 
        
                <asp:LinkButton ID="lnkOpenClientClick" Text="click here to open dialog - onclientclick" 
        
                    runat="server" OnClientClick="openRadWindow();return false" /> 
        
                <br /> 
        
                <br /> 
        
                <asp:LinkButton ID="lnkOpenServer" Text="click here to open dialog - server response" 
        
                    runat="server" /> 

                <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">  
        
                    <script type="text/javascript">  
        
                            <%=_scriptToRun%> 
        
                    </script> 
        
                </telerik:RadCodeBlock> 
        
            </asp:Content>

3) Default.aspx.vb

    
            Partial Class Test_default  
        
                Inherits System.Web.UI.Page  
        
                Public _scriptToRun As String  
        
                Protected Sub lnkOpenServer_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lnkOpenServer.Click  
        
                    _scriptToRun = "openRadWindow();" 
        
                End Sub  
        
            End Class

You can see that there are two buttons, one using OnClientClick, one using server postback. The former one works as your demo. However, if I run the latter one, it doesn't work, and comes up with error.

I want to use the second method (server postback) because I need to verify something before i popup the window.

Thanks

Hi Raymond,

About the showMessageWindow function :
This error may be caused if you open a first RadWindow outside of the RadWindowManager and its get_windowManager() function returns 'null' respectively.
In your case, you need to declare the first opened RadWindow inside the <window> collection of the windowmanager as follows :

    
            <telerik:RadWindowManager ID="RadWindowManager1" runat="server"> 
        
                <Windows> 
        
                    <telerik:RadWindow ID="RadWindow1" runat="server"> 
        
                    </telerik:RadWindow> 
        
                </Windows> 
        
            </telerik:RadWindowManager>

As alternative, also, you can open the first window by using the radopen() function (I recommend that approach). This function creates and opens a new window (if the window already exists, it will not be created) and adds it to the window collection automatically( if it does not exist in the collection). In this case I recommend you remove the first RadWindow declaration from the page or move it in the window collection of the RadWindowManager.

In reference to the second question : More details about opening the RadWindow from codebehind and full working demos can be found on this KB article.

I hope this helps.
