Hi

I want to use buttons to switch view instead of the build in view switcher. I switch the view by code like this

 public void btnGroups_Clicked(object sender, ClickedEventArgs e)
        {
            this.ViewInfos.SwitchView("GroupView");
        }

What I have noticed is that if I'm on a quite large view with a long repeating table it can take several minutes to switch view by the button compared to use the built in switch view drop down. How can this be?

 BR,
Niclas

Forgot to say that this is a form that runs under InfoPath Forms Services
