How can I access an IFRAME from the codebehind file in ASP.NET?

Question

I came across a post that says you can use FindControl to find the non-as

Answer 1

Try this.

ContentPlaceHolder cplHolder = (ContentPlaceHolder)this.CurrentMaster.FindControl("contentMain");

HtmlControl cpanel= (HtmlControl)cplHolder.FindControl("contentPanel1");

Answer 2

If the iframe is directly on the page where the code is running, you should be able to reference it directly:

contentPanel1.Attribute = value;

If not (it's in a child control, or the MasterPage), you'll need a good idea of the hierarchy of the page... Or use the brute-force method of writing a recursive version of FindControl().

Answer 3

aspx page

<iframe id="fblikes" runat="server"></iframe>

Code behind

this.fblikes.Attributes["src"] = "/productdetails/fblike.ashx";

Very simple....

Answer 4

This works for me.

ASPX :

<iframe id="ContentIframe" runat="server"></iframe>

I can access the iframe directly via id.

Code Behind :

ContentIframe.Attributes["src"] = "stackoverflow.com";
