How to keep a window on the screen

[David]

Hey guys

I'm new to telerik and I'm facing a big problem. I'm developping a web application and I need, when I click on a button, to make appears a new window (window B) inside the current window (windows A). So, I followed this demo http://demos.telerik.com/aspnet-ajax/fileexplorer/examples/client-sideapi/fileselectordialog/defaultcs.aspx, but there's still a problem. The window B appears over the window A, but I can drag it "out" of the windows A and a scrollbar appears. So, I tried to put a RestrictionZoneID (using css) that will block the window B at the edge of the window A by using the current resolution of the screen, but I don't know how to find the resolution in css. Can someone help me ? In fact, the best would be that my window have the same behavior that any Microsoft window.

Hello David,

I'm assuming window A is the browser window and not a RadWindow. If so, you can set the property KeepInScreenBounds="true" on your RadWindow (window B) to keep it within the visible viewing area.

I hope that helps.

Thank you,

It works, but I still can move my window B out of the screen. It just when I stop holding my window that it go back in browser. It would be gret if it wasn't that I use silverlight and when I get the window B out of the screen, my silverlight app start lagging.
So, please, any other idea ?

Hello David,

This is the way browsers handle movable elements - they allow you to drag them outside of the screen or set their position to be outside of the screen through code. You can observe it with any movable element, not just RadWindow.

If you want the RadWindow to stay within a specified area you can use the RestrictionZone property as shown in the following Online Demo: http://demos.telerik.com/aspnet-ajax/window/examples/restrictionzone/defaultcs.aspx. Please note that you would need to have an html element to act as the zone that restricts the RadWindow, it cannot be done via CSS only.

Also note that the behavior of a Microsoft window is that it can also be dragged outside of the screen if it is not maximized or minimized. This is also true for the RadWindow.

Kind regards,
