RadWindow hide from javascript tricks

[cs137]

I have RadWindow opened as modal within page. RadWindow has the only button (LinkButton):

<asp:LinkButton ID="lbProceed" runat="server" CausesValidation="false" OnClientClick="radWnd.Hide();" OnClick="Proceed_Event">Proceed</asp:LinkButton>

So when i click button clients script hides RadWindow and postback doesn't occurs (FF 3.6.12) but when i remove client click event it works ok. On Chrome 7 it works with client side event but i get javascript errors "Failed to load resource" ref to my radwindow page just after postback.

Another one thing... If I hide RadWindow from OnClientClick (as descibed above) and after postback on page load form javascript i am trying to change radwindow size or/and its position:

 GetRadWindow().setSize(GetRadWindow().getWindowBounds().width, height);

                GetRadWindow().center();

$(document).ready(function () {
   GetRadWindow().setSize(GetRadWindow().getWindowBounds().width, height);
   GetRadWindow().center();
});

RadWindow becomes visible again. But if i remove above javascript RadWindow will stay invisible after postback.

I use: Telerik.Web.UI, Version=2010.3.1109.40

Hello Stephan,

Basically, calling center() on a RadWindow object will show it as this is part of its logic. As for the first problem however, I was not able to reproduce it. Could you please post full sample code that shows your exact setup?


All the best,

Hello Georgi,

Here is a simple asp.net project with default page and popup page. On the default page there is the only link button. Popup page opened as Radwindow by clicking on it. In popup page there is another one link button that has two client and server side events. Client event (OnClientClick) just hides RadWindow and server-side event redirects main page to current forum thread:

Hello Stephan,

Thank you for the sample - now I have a better view over your setup. To avoid the problem I would suggest not to hide the RadWindow in OnClientClick and to leave only the location setting in the codebehind - there is no need to close a hidden window when you are navigating the parent page to another location - RadWindow will be destroyed anyway.

this.Page.ClientScript.RegisterStartupScript(this.GetType(), "modifyconfirm", "GetParentWindow().location = 'http://www.telerik.com/community/forums/aspnet-ajax/window/radwindow-hide-from-javascript-tricks.aspx';", true);


In addition, if the parent page is the topmost page (i.e. the one directly loaded in the browser), you can remove GetParentWindow as well and replace it with top.
e.g. top.location.href = "http://myurl.com";


Best wishes,

Hello Georgi,

Thanks for your reply. It seems to it is FF issue. I played a little with items hiding (by adding display=none style) and there is no postback in FF when item has display=none. All other browsers work ok in above case.
