Is there any standard defined for Javascript showModalDialog method?
<p>I am displaying data in GridView control (Visual Studio 2008). My client has asked to show a dialog once user clicks a cell but he has asked it as a <strong>modal</strong> window. This is to edit a cell. In-cell editing cannot be used because information to be collected is complex and would require lot of controls along with another GridView.</p>

<p>After searching on net, I came to know that showModalDialog Javascript method (on Window object) would work - seems that it works in FF and IE and that's sufficient for me.</p>

<p>Now my question : Is there any standard body (or recommendation) which defines Javascript Window object (and consequently its showModalDialog method)?</p>

<p>I know Standard ECMA-262 ECMAScript Language Specification defines just core Javascript. When I looked at various standards (or recommendations) set by W3C - XHTML, DOM, etc. But I could not find any standard (or recommendation) for Window object.</p>
