Adgang til en UserControl fra en anden UserControl
Jeg har fundet denne tutorial på nettet og déns eksempel virker finthttp://fredrik.nsquared2.com/viewpost.aspx?PostID=377
- dog kan jeg ikke få mit eget eksempel til at virke. Jeg har et multiview i én UserControl og og linkene dertil i en anden.
Men det er ligesom at den ikke får adgang UserControlen med multiview'et da jeg får den samme fejlmeddelse hver gang:
Navnet 'MultiView1' findes ikke i den aktuelle sammenhæng *
