can i add a radwindow to a masterpage

[Anwar]

i want to add the rad window to the master page and inherit it, but it gives me an error "Microsoft JScript runtime error: Unable to get value of the property 'show': object is null or undefined"
I have added this as follows

<%

-- "About" window --%>

 

<telerik:RadWindow runat="server" ID="AboutWindow" Overlay="false" VisibleStatusbar="false" Behaviors="Move,Close" Animation="None" Modal="true" Title="About This Demo" Width="490px" Height="425px" IconUrl="Images/about_icon.png" OnClientShow="aboutWindowShow">

 

<ContentTemplate>

 

<uc:About runat ="server" ID="AboutDialog" />

 

</ContentTemplate>

 

</telerik:RadWindow>


and i have added this function

 

function buttonClicked(sender, args) {

if (args.get_item().get_index() == 0)

$find(

 

'AboutWindow').show();

  

 

}

can you tell me what i am doing wrong

Hi Anwar,

The master page creates INaming containers, which means that the controls' client-side IDs are not the same as the ones you use on the server. You would need to use server code blocks to get the correct id:

$find('<%=AboutWindow.ClientID%>').show();

Note that this has to be in the master page as well if you need to call this function from a content page I would suggest adding a function to return a reference to this RadWIndow in the master page and call if from the content pages:

function getRW(){
   return $find("<%=AboutWindow.ClientID%>");
}

and

getRW().show();
