    </div>
    </form>
</body>
</html>

Auf .cs -Code dahinter möchte ich den folgenden Code verwenden

if (! page.ispostback) {webuSerControl1 uc = (webuSerControl1) Page.loadControl ("webuSerControl1.ascx"); Placeholder1.Controls.Add (UC); }

- aber

Keiner der UserControls scheint, wenn ich "webuSercontrol1" durch Name Cheader ersetze, heißt es in Cheader? Was ist das!!

ASP.NET C# VSTS2008

War es hilfreich?

Lösung 2 

protected void Page_Load(object sender, EventArgs e)
{

    Control details = LoadControl("WebUserControl.ascx");
    PlaceHolder1.Controls.Add(details);


    Control details1 = LoadControl("WebUserControl2.ascx");
    PlaceHolder2.Controls.Add(details1);



}

das funktioniert :-)
