Hello again, I've solved this problem. I had to delete the view of the SPList before: I just add the following code at the end of AddView():
try
{
SPView view = m\_InventList.Views\["Overview"\];
if (view != null)
m\_InventList.Views.Delete(view.ID);
}
catch (System.Exception)
{
}
m\_InventList.Views.Add("Overview", strColl, @"", 200, true, true, SPViewCollection.SPViewType.Html, false);
m\_InventList.Update();
Best regards nki
