I use aradwindowManager on my page. In a "TextChanged" event I want to add a new window to the manager. I use follwing code in code behind:

    
                                objWindow = New RadWindow  
        
                                objWindow.ID = "rwSearchShiftNo" 
        
                                objWindow.OpenerElementID = "lnkSearchShiftno" 
        
                                objWindow.NavigateUrl = "search.aspx?searchtype=shiftno&show=yes" 
        
                                objWindow.ClientCallBackFunction = "SearchDialogCallBackFunction" 
        
                                rwmSearchDialog.Windows.Add(objWindow)

The problem is that when I click nowe on the specified control defined in "OpenerElementId" nothing happens. What am I doing wrong?

Hello Georgi,

the Textchanged event is not the problem: Here is the complete code, just run the project and follow the instruction.

Hi Markus,

You are adding the RadWindow to the RadWindowManager's Windows collection, however you are using Ajax and you don't update the manager itself - that is the reason for the problem. If you add the RadWindowManager to the updated controls' collection, the window will be shown.

    
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">   
        
                <AjaxSettings>  
        
                    <telerik:AjaxSetting AjaxControlID="rcboTest">   
        
                        <UpdatedControls>  
        
                            <telerik:AjaxUpdatedControl ControlID="rcboTest" />  
        
                            <telerik:AjaxUpdatedControl ControlID="lnkSearchShiftno" />  
        
                            <telerik:AjaxUpdatedControl ControlID="rwmSearchDialog" />  
        
                        </UpdatedControls>  
        
                    </telerik:AjaxSetting>  
        
                </AjaxSettings>  
        
            </telerik:RadAjaxManager>

Hello Markus,

This is due to the way the Ajax update panel works. What you can do is to hook to the RadAjaxManager's AjaxSettingCreating event and set the render mode of the panel to Inline:

    
            Protected Sub RadAjaxManager1_AjaxSettingCreating(ByVal sender As Object, ByVal e As Telerik.Web.UI.AjaxSettingCreatingEventArgs) Handles RadAjaxManager1.AjaxSettingCreating 
        
               e.UpdatePanel.RenderMode = UpdatePanelRenderMode.Inline 
        
            End Sub
