Hi,

I am currently using RadControls for ASPNET AJAX Q1 2009. My Virtual Machine is Windows Server 2003 Service Pack 1.

I am using the RadEditor but the Image Manager Dialog produces a "Page cannot be found error" intermittently. If I refresh the IE page and try again, it would display the Image Manager Dialog and I would be able to Upload, Insert or Delete images. But if I refreshed again the "Page cannot be found error" will return.

I used the DialogHanderURL in the RadEditor tool.

    
             <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">  
        
             <ContentTemplate> 
        
             <div style="text-align:left;padding-top:3pt;padding-bottom:3pt">  
        
             <asp:Label ID="lblMessage" runat="server" Text=""   Font-Names="Tahoma" Font-Size="12px" ForeColor="red"></asp:Label><BR/>  
        
             <telerik:RadEditor ID="DocManagementRadEditor" runat="server"      Width="685px"                  
        
            Height="340px"   
        
            EditModes="Design"   
        
            ToolsFile="~/EditorTools/NoTools.xml" 
        
            CssClass="DMDropDown" 
        
            DialogHandlerUrl="~/Telerik.Web.UI.DialogHandler.aspx">  
        
            <Content></Content>  
        
            </telerik:RadEditor>   
        
                                <asp:Button ID="btnSubmit" runat="server" Text="Submit" style="display:none;"/>  
        
                                <script type="text/javascript">  
        
                                Telerik.Web.UI.Editor.CommandList["Save"] = function(commandName, editor, args)  
        
                                {  
        
                                   //alert("Save In Database");  
        
                                   var btnSubmit = $get("<%=btnSubmit.ClientID%>"); //get a reference to the Asp:Button  
        
                                    btnSubmit.click(); //click it programmatically  
        
                                };  
        
                                </script> 
        
                               </ContentTemplate> 
        
                                   <Triggers> 
        
                                       <asp:AsyncPostBackTrigger  ControlID="DocumentSubTypeDropDown" 
        
                                        EventName="SelectedIndexChanged"/>  
        
                                   </Triggers> 
        
                               </asp:UpdatePanel>

Then on load of the page I specified the ViewPaths, DeletePath and UploadPath

    
             Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
        
                    If Not Page.IsPostBack Then  
        
                        Try  
        
                            Dim viewImages As String() = "~/app_upload"  
        
                            DocManagementRadEditor.ImageManager.ViewPaths = viewImages 
        
                            DocManagementRadEditor.ImageManager.DeletePaths = viewImages 
        
                            DocManagementRadEditor.ImageManager.UploadPaths = viewImages 
        
                        Catch ex As Exception  
        
                            WriteToEventLog(ex.Message, EventLogEntryType.Error)  
        
                        End Try  
        
                    End If  
        
                End Sub

Weird thing is, when I accessed my Virtual machine application or in other environments using my host/base machine which is XP IE7 and before IE6 SP2, it works without any problems even after many refresh. Some of our clients also experience this intermittent behavior. Is this a browser setting issue? Any help is greatly appreciated.

Thanks,
Rachell
