Radwindow wont open after code is processed on RadMultiPage

[newguy]

Hi Guys,

Im busy creating a betting application using C# asp.net.
Pretty much what happens is, at betting sites cashiers will log onto the website and may generate a voucher which is printed and given to customers.

I am using a masterPage, the RadScriptManager and AjaxManager are found on the master page.
My Sales.aspx page which has a RadAjaxPanel which holds a RadMultiPage control that has 2 tabs (scratchcards and vouchers).

My Voucher Tab has a Button (Generate) which will randomly generate a voucher PIN and is supposed to open a rad window after all the code has been executed which it fails to do.

Just as a Test i dropped a button on the page (Outside of the Panel) and was able to successfully open the rad window with that button, but the RadWindow does not open if i try open it from the Generate Button held inside of the MultiPageView Control.

Any Ideas Why?

aspx code for my Panel

                }
            }
        }

Code i am using to open the RadWindow on the button outside of the PageView (This code works only if it is not inside of the PageView)

protected void RadButton1_Click(object sender, EventArgs e)
    {
        RadWindow newWindow = new RadWindow();
        newWindow.NavigateUrl = "http://www.google.com";
        newWindow.Top = Unit.Pixel(22);
        newWindow.VisibleOnPageLoad = true;
        newWindow.Left = Unit.Pixel(0);
        RadWindowManager1.Windows.Add(newWindow);
    }

Thanx in advance

Hello,

I see you add a newly generated RadWindow to the Windows collection of a RadWindowManager. This manager, however, is not in the RadAjaxPanel, so it is not updated in the browser, which means that the new RadWindow is not transferred to the client.

What I would advise:
- use the approach from this sticky thread to open the RadWindow: http://www.telerik.com/community/forums/aspnet-ajax/window/opening-radwindow-from-the-server.aspx. You can declare it in the RadWIndowManager Windows collection in the markup. You can additionally use its Client-side API to modify it in the function that will open it. This help article will show you other ways to open a RadWindow with JavaScript if you do not want to have it in the markup: http://www.telerik.com/help/aspnet-ajax/window-programming-opening.html. You will see how the RadWIndowManager can create RadWIndows on the fly

- if that is not a viable option for you, you can simply add the RadWindow to a placeholder inside the RadAjaxPanel. Note that, in this case, you would need to treat it like any other dynamic ASP contorl - recreating it after a postback will be needed. The RadWindowManager otherwise stores its Windows collection in the ViewState. I would still advise on opening it with a script registration, however, instead of using the VisibleOnPageLoad property.

Hi Martin,

thank you for the reply.

I found another way around it, instead of using the RadWindow i used an iframe that is loaded far off the screen (left: -10000px).
so as soon as the iFrame opens it prints the voucher and then closes the iFrame.

sorry for the late reply.
