The ClientUI navigation framework is built around the commanding semantics which allows certain features of the navigation to be executed through declarative definition in the XAML markup. The commanding semantics is also an ideal approach for MVVM pattern development.

The following code example shows how to navigate to a page using BrowseBack command assigned in a button.

Note: the code is implemented in the ViewModel using DelegateCommand-ing.

private void NavigateCommandAction(object parameter)
{
    NavigationCommands.BrowseBack.Execute(null, (UIElement)ISFocusManager.GetFocusedElement());
            
}

Hope this helps.

Thanks...whatabout this part, thanks

Can I also ask how to navigate to a new page but open a new instance through code.

I can see you use targeturi= _blank when in  xaml but not sure how to do using MVVM

In order to navigate to a new page but open a new instance through code, we need to set the value of NavigateUri and TargetName.

For example:

<Intersoft:UXNavigationButton x:Name="UXNavigationButton1"
                              Content="Community"
                              NavigateUri="http://www.intersoftpt.com/Community/"
                              TargetName="_blank" />

To do this using MVVM, we need to have two string type properties in the ViewModel and bind them to NavigateUri and TargetName.

Hope this help.
