how to get the src of a iframe

[guoqi zheng]

Dear sir,

I know how to set the src of a iframe, for example, I can use
Dim frame1 As HtmlControl = Page.FindControl("itest")
frame1.Attributes("src") = Me.TextBox1.Text.Trim

However how can I get the current src of a iframe after user clicking
several times on the iframe??? when I try to get the value of frame1.
Attributes("src"), what I get is the original src I set to it.

How can I do this?

this is only known at the client. you could use some ajax approach to notify
the server of a src change.

Tell me, while user click on the frame, what do you expect src to change?

for example, when user on google.com site and clicks "news", I expect src
changes to "http://news.google.com"

any idea?

Get the source property of IFrame

you need to do a findcontrol to identify the control on the page and typecast it as follows:-

C#
HtmlControl frame1 = (HtmlControl)this.FindControl("frame1");

VB.NET
Dim frame1 As HtmlControl = CType(Me.FindControl("frame1"), HtmlControl)

Note: You can have different name for the Generic Control you define in the code behind, but for ease I keep both the same. The "frame1" referred in Find Control is the ID as declared in the ASPX Page.

Thereafter, you will be able to access the src property as follows:-

C#
frame1.Attributes["src"] = http://megasolutions.net;

VB.NET
frame1.Attributes("src") = http://megasolutions.net
