Make the links in the user control always relative to the project root--e.g.
"~/images/myLogo.gif".

But when i use this usercontrol in a folder... the user control search:
/newFolder/images/logo.gif

Use the literal "~" in your links per my example, which represents the
project root and means the search will always start at the top, no matter
where you put your user controls, pages, etc.

ok.
But the error now is:
http://localhost/DemoWeb/~/Images/mmc.gif

Mi VS.Net no understand the literal "~" en my link
The image is in:
http://localhost/DemoWeb/Images/mmc.gif

no exists the folder "~"

thanks

ok.
But the error now is:
http://localhost/DemoWeb/~/Images/mmc.gif

Mi VS.Net no understand the literal "~" en my link
The image is in:
http://localhost/DemoWeb/Images/mmc.gif

no exists the folder "~"

~ only works in server controls (or more correctly, in any expression that
is processed on the server). So, for instance:
<img src="~/images/test.gif" runat="server">
or
<asp:Image ImageUrl="~/images/test.gif" runat="server">
will work.

<img src="~/images/test.gif">
will NOT work.

Of course you can also assign these values programmatically, or in a
databinding expression.

Thanks for all's inputs.

Hi Francisco,

I think Riki's suggestion is quite reasonable. The "~" char does maps to
Application root fo asp.net application, but it only works for serverside
control attributes bydefault. The clientside browser won't recognize this
char. As for programatically mapping "~/..." to clientside readable url, we
can use
Control.ResolveUrl method to do the translation.


#Control.ResolveUrl Method
