Question

I have a class that is a viewmodel (using Prism). It has an associated XAML view. When I do

this.Cursor

there isn’t any Cursor property available. What must I do in order to access the cursor so I can change its icon?

Answer 1

Since the Cursor is a UI-related property, you should set the cursor in the View, not the ViewModel. this.Cursor should work fine from the code-behind the View

If your Cursor is based on something in the ViewModel such as if it’s loading data, then use a DataTrigger in your XAML to change the Cursor when something like an IsLoading property is set to true

<Style TargetType="{x:Type Window}">
    <Style.Triggers>
        <DataTrigger Binding="{Binding IsLoading}" Value="True">
            <Setter Property="Cursor" Value="Wait" />
        </DataTrigger>
    </Style.Triggers>
</Style>
