Server | Source code The following example implements the HTML source code for an editable iframe on the server side. The code is simple, the pain here is not much explained. The code is as follows:
Getiframehtml.axpx
<%@ Page language= "<a href=" http://dev.21tx.com/language/vb/"target=" _blank ">VB</a>" Validaterequest=false autoeventwireup= "false"
codebehind= "Getiframehtml.<a href=" http://dev.21tx.com/web/asp/"target=" _blank ">asp</a>x.vb" inherits= "Aspx<a href=" http://dev.21tx.com/web/target= "_blank" >WEB</A>. Getiframehtml "%>
<HTML>
<body>
<form id= "Frmmain" method= "POST" runat= "Server" >
<iframe id= "ifrhtml" name= "ifrhtml" ></iframe>
<br>
<asp:button id= "Cmdsend" runat= "Server" text= "Submit" ></asp:Button>
<input type= "hidden" name= "Hidvalue" >
</form>
<script>
IfrHTML.document.designMode = "on";
</script>
</body>
</HTML>
