vb.net中vs2010的iFrame可见性

Question

Is there any way to set the visibility of an iFrame dynamically?

Tried researching on the web but couldnt find any.

Answer 1

You could add a runat="server" tag to the iframe:

<iframe src="..." id="myframe" runat="server"></iframe>

and then in your code behind you could access it my id and set properties:

myframe.Visible = False

Note that by setting its Visible property to False the iframe will not be rendered at all in the output HTML. If you wanted to hide the iframe on the client only you could manipulate its Attributes or Style properties.
