I have an asp.net website with a master-page, can I use the iframe so my .aspx pages will load inside the iframes. (Meaning it wont load the master-page)
Kinda like my iframe will be the contentplaceholder or maybe the contentplaceholder will be inside it?
Any Ideas?
This question is related to
c#
asp.net
iframe
contentplaceholder
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 />"));
You can think of an iframe as an embedded browser window that you can put on an HTML page to show another URL inside it. This URL can be totally distinct from your web site/app.
You can put an iframe in any HTML page, so you could put one inside a contentplaceholder in a webform that has a Masterpage and it will appear with whatever URL you load into it (via Javascript, or C# if you turn your iframe into a server-side control (runat='server') on the final HTML page that your webform produces when requested.
And you can load a URL into your iframe that is a .aspx page.
But - iframes have nothing to do with the ASP.net mechanism. They are HTML elements that can be made to run server-side, but they are essentially 'dumb' and unmanaged/unconnected to the ASP.Net mechanisms - don't confuse a Contentplaceholder with an iframe.
Incidentally, the use of iframes is still contentious - do you really need to use one? Can you afford the negative trade-offs associated with them e.g. lack of navigation history ...?
How about:
<asp:HtmlIframe ID="yourIframe" runat="server" />
Is supported since .Net Framework 4.5
