I tried the &lt;video&gt; tag of html5, and it runs the mp4 file OK (If I define the src attribute in the HTML code, however, what I want to do is to pass the video url to the web form as query string, and do not know how to change the src property dynamically. even when I try to user thevideo.attributes.add for the &lt;video&gt; tag marked as runat=&quot;server&quot; and ID=&quot;thevideo&quot; I get an error showing the ID &quot;thevideo&quot; of the Video element is not known to the code. Can some help please. Thanks

The current implementation of the HTML specification is HTML5.

HTML

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
