Using iFrames In ASP.NET
try this
<iframe name="myIframe" id="myIframe" width="400px" height="400px" runat="server"></iframe>Expose this iframe in the master page's codebehind:
public HtmlControl iframe{get{return this.myIframe;}}Add the MasterType directive for the content page to strongly typed Master Page.
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits=_Default" Title="Untitled Page" %><%@ MasterType VirtualPath="~/MasterPage.master" %>In code behind
protected void Page_Load(object sender, EventArgs e){this.Master.iframe.Attributes.Add("src", "some.aspx");}
Another option is to use placeholders.
Html:
<body> <div id="root"> <asp:PlaceHolder ID="iframeDiv" runat="server"/> </div></body>C#:
iframeDiv.Controls.Add(new LiteralControl("<iframe src=\"" + whatever.com + "\"></iframe><br />"));
How about:
<asp:HtmlIframe ID="yourIframe" runat="server" />Is supported since .Net Framework 4.5
