Use the Top and Left properties to specify the position of the window relative to the HTML page. Top and Left give the offset, in pixels, of the top left corner of the window. Checkout the following documentation for more information.
Showing and Positioning
here is the script..
bc i want to make it work in IE8 because in Firefox it seems to work
I noticed that you RadWindow is modal and indeed, by default the when a RadWindow is modal, it is shown in the middle of the screen and this is by design. The RadWindow control is intended to replace the standard popup wndows called with window.showModalDialog and all the modal standard windows are always shown at the center of the screen and thus the RadWindow is implemented to behave the same way.
In order to get the desired result, you can use the moveTo(x, y) method of the RadWindow once you have shown it - this will make it position at the desired coordinates.
I hope that my explanations and suggestion are helpful, let me know how it goes and in case you need further assistance or you have additional questions.
