    Internet Explorer allows you to set / resize the height of a radwindow to be very small, even down to 0px. However, every other browser I've tested only allows the height to go down to about 100 pixels. Am I missing something obvious or does anyone know a workaround to make a radwindow's height about 50px on every browser? Thanks!

    Hi Jim,

    The problem comes from a bug with Gecko / Webkit browsers. They incorrectly renders tables with iFrames in it when the height is less than about 150 pixels (the RadWindow is basically an IFRAME). You could test it by adding the following code in an aspx page. You will notice that the height of the IFRAME is not 100px but about 150px (the code below is actually the basic RadWindow's structure when RadWindow loads external page):
    <table style="height:100px;border:3px solid green">  
        <tr style="height:100%"
            <td style="height:100%"
                <iframe style="border: 1px solid red; height:100%" src=""></iframe>

    To be able to use a popup with such small height, I should use RadWindow as a controls container, i.e. to have the content on the main page. In such case, RadWindow does not use IFRAME, but renders a DIV element and the browsers' bug will not affect the height. More information on how to use RadWindow as a controls' container is available in the demo above and in this help article.
