Hi Marko,
You need to get a handle on the control itself and then you can mess with its
properties. Here's the idea, full code below:
Dim tpban As UserControl
Dim tpbanimage As System.Web.UI.WebControls.Image
tpban = Page.FindControl("Tpbanner1")
tpbanimage = tpban.FindControl("image1")
tpbanimage.ImageUrl = "
http://www.gc.ca/images/francaisbt.gif"
tpbanimage.ID = "newid"
Does this help?

Microsoft MVPs have a question for *you*: Are you patched against the Worm?
http://www.microsoft.com/security/security_bulletins/ms03-026.asp
I am interested in accessing a property from a use defined web control from
the codebehind of an aspx page.
If my web control has a property, say Name, how would I reference the
control in my aspx code so that I can access that instance of the control?
I beleive (though I have not tried) to create an instance by it's full
assembly name, but I want to use the one that is currently loaded in that
aspx page.
