Custom Close radwindow

[wnl]

Hi,
I want to override default close in radwindow (at top-right icon).
I tried in js:

TelerikTelerik.Web.UI.RadWindow.prototype.oldClose = Telerik.Web.UI.RadWindow.prototype.close;
Telerik.Web.UI.RadWindow.prototype.close = function(callBackFnArg) {
    //your code goes here
    alert("closing");
    //call old close method
    this.oldClose(callBackFnArg);
};

but I get an error about: no definition of 'Telerik'.
So how can I write my own close function in js?

Hi Jaromin,

In the newer versions of the RadWindiow control (Q3 2008 and later) we implemented an OnClientBeforeClose event. In your case you could use this event and implement your logic in its handler. Also you could cancel the close by using the following simple approach :

• attach the event handler :
  

  <telerik:RadWindow ID="RadWindow1" runat="server" OnClientBeforeClose="OnWindowCloseHandler">
  </telerik:RadWindow>

• Implement the handler as follow :
  

  function OnWindowCloseHandler(oWindow, args)

  {

  // Your logic here ...

  // You could cancel the closing

  args.set_cancel(true);

  }

I hope this helps.
