Getting RadMaskedTextBox Client Object on other Page.

Hi,

I have a RadMaskedTextBox on Page A.aspx, I navigated to some other Page B.aspx with the Id of RadMaskedTextBox of Page A.aspx.
Now I need to get the client side object of RadMaskedTextBox on page B.aspx to manipulate its value.

I can not use
var maskedTextBox = $find("<%= RadMaskedTestBox1.ClientID %>");
because, the control is not on page B.aspx.
Is there a way to achieve, what I am trying to do..?

Has the default skin changed since Q3 2008?

Hello

I am looking at your online demo for the form decorator as found here

http://demos.telerik.com/aspnet-ajax/formdecorator/examples/default/defaultcs.aspx

As you can see on this page when you use teh default skin buttons are displayed in grey with a rollover effect.

I am using the Q3 2008 release and when I use the default skin with the form decorator the button is black with no rollover. If you look at the bottom of this page in the Different Skins section

http://www.telerik.com/products/aspnet-ajax/formdecorator.aspx

where some controls are shown in all the different skins the default button is black.

So using the form decorator and the default skin in the new telerik release, what colour is the button? Black or grey?

I like the default skin as it is and I am hoping it has not changed in the new telerik release. In fact I don't want to upgrade to the new relaase if the default skin has changed since the end of last year.

Thanks

HelpDesk demo app... where?

There used to be a sample HelpDesk app that ran in ASP.NET demos section... but it has disappeared, and been replaced with a WebMail app, which is quite different and unsuitable for HelpDesk use.,

Is the old demo still available to run anywhere?

cheers

Get a Client Side Reference to MOSSRadEditor Instance

I have several MOSSRadEdtior controls on a MOSS publishing page. How can I get a reference to each instance? Is there a global function that I can pass in the ClientID of the control? I saw a GetRadEditor() function in the client API, but it did not seem defined when I tried to call it.

Thanks!

Controls and Grid not refreshing in WindowManager Content Page popup

I have a button in my grid that uses a WindowManager to open a RadWindow. In the popup RadWindow I add a new record to a list using some drop downs and textboxes. After I click Add I want the controls to be cleared and the grid below to be refreshed with the new record. I added a RadAjaxManagerProxy to this page and tried to point to those controls to be updated but nothing happens. When I press the refresh on the grid itself then the record shows up but otherwise everything on the popup page remains unchanged.

How do I get the controls on this page to refresh properly?

RadAjax, RadMenuToolBar and several usercontrols

Hello Telerik,

I am currently building an application using a RadAjax, RadMenuToolBar and several usercontrols. the following example describes my problem. I have a RadMenuToolBar with 2 toggle buttons where the buttons have their own group(Group1 and Group2) and 2 UserControls. When I select the first button, then the first usercontrol should be updated. Then when I click the second button, the second usercontrol must be updated, but the first usercontrol must not be updated again. how can I achieve this kind of situation with RadAjaxManager?
I could use asp.net UpdatePanel, by wrapping each usercontrol and the MenuToolBar with updatePanel. and in the RadMenuToolBar's OnButtonClick I called UpdatePanel's Update method based on the clicked button, but I prefer to use RadAjaxManager if it's possible.

below is my current code:

    
            <telerik:RadAjaxManager runat="server" ID="radAjaxManager">  
        
                        <AjaxSettings> 
        
                            <telerik:AjaxSetting AjaxControlID="radToolBar">  
        
                                <UpdatedControls> 
        
                                    <telerik:AjaxUpdatedControl ControlID="userControl1" /> 
        
                                    <telerik:AjaxUpdatedControl ControlID="userControl2" /> 
        
                                </UpdatedControls> 
        
                            </telerik:AjaxSetting> 
        
                        </AjaxSettings> 
        
            </telerik:RadAjaxManager> 
        
            <telerik:RadToolBar ID="radToolBar" runat="server" OnButtonClick="RadToolBar_ButtonClick" AutoPostBack="true">  
        
                        <Items> 
        
                            <telerik:RadToolBarButton runat="server" Text="firstButton" CheckOnClick="true" AllowSelfUnCheck="true" 
        
                                Value="firstButton" Group="Group1" /> 
        
                            <telerik:RadToolBarButton runat="server" Text="secondButton" CheckOnClick="true" AllowSelfUnCheck="true" 
        
                                Value="secondButton" Group="Group2" /> 
        
            <uc1:UserControl1 runat="server" ID="userControl1"/>  
        
            <uc1:UserControl2 runat="server" ID="userControl2"/>

I'm looking forward to your reply. Thanks in advance.

Cheers,

Thomas
