second radwindow showing behind first when the first is maximized

[Leonardo Amorim de Barros]

I want to open a radwindow from another radwindow. The problem occurs in this situation:

I hava maximized the former radwindow, after that, i try to open another radwindow, despite i set the modal to true, and active to true, the second form opens behind the first one. I don't know why this happens. The problem doesn't occurs if the form is restored.

thanks,

Leonardo.

Hello Leonardo,

By default, if the RadWindow control is maximized it appears above all HTML elements on the page and this behavior cannot be changed. What I can suggest in scenario like yours is:

• if you open the WindowB from maximized WindowA
  
  • attach a function to the OnClientClose event of the WindowB
  • in this function maximize the WindowA ( because it was restored in the next steps)
  • after minimal timeout restore the WindowA, then set modal behavior of the WindowB
  • if you close the WindowB the WindowA will be maximized ( OnClientClose event was fired )
• if you open the WindowB from not maximized WindowA - you simply need tp set desired behavior of the WindowB after some timeout.

For your convenience I attached a simple project to this thread that demonstrates the described approach.

I hope this helps.

Kind regards,

Hi Fiko,

I downloaded your example, created a project, set the default.aspx as start page, included the reference of telerik and ran the example.

I clicked on the "button", then another window was opened, after that, i maximized the window (Popup.aspx) and clicked on "New Button Modal", an error appears, which message was:

Run-time error in Microsoft JScript: Sys.ArgumentTypeException: Object of type 'Object' cannot be converted to type 'Function'.
Parameter name: handler

the error occurs in this method: 

Function.createDelegate =

function Function$createDelegate(instance, method) {

Hello Leonardo,

This problem could appear if your web.config is not configured to use ASP.NET AJAX. For convenience I attached my configuration file (.Net 3.5) - please add it in the project that I previously sent and let me know how this goes.

Hi Fiko,

I looked to the code you sent me, and i noticed that was a similiar way that i did, but i didn't want to resize the window. But i think it is the only way, or i can hide the button maximize.

thanks

Hello Leonardo,

Yes, if you remove  the "Maximize" button from the RadWindow control, then you do not need the provided workaround. However if you need to have a maximized RadWindow, you should use the approach that I described before.
