What is the best way to automatically adjust a panel's width and height based on the user's screen resolution?

My page is connected to a masterpage. Within this page, I have an update panel that contains an ASP.NET panel.

The panel includes a gridview displaying data from the database. Currently, I have set a fixed width and height for the panel. However, if the user's screen resolution is larger than the specified dimensions, it results in blank spaces.

To prevent this issue, I discovered that JavaScript can be used to determine the user's screen resolution. I successfully tested this on a standalone page by calling the JavaScript function within the body of that page. However, I'm unsure how to implement this on a page connected to a masterpage.

    pageManager.add_beginRequest(handleBeginRequest);
    pageManager.add_endRequest(handleEndRequest);

    function setWidth(width)
