Implementing commands in MMVM
- by user312372
I am trying to change the source property of the frame in Page1.xaml when the SampleCommand is excecuted.
How do I acheive this in the View Model?
Page1.xaml:
<Page ...>
<DockPanel>
<r:ribbon>
<r:RibbonTab Label="Keys">
<r:RibbonTab.Groups>
<r:RibbonGroup GroupSizeDefinitions="{StaticResource RibbonLayout}">
<r:RibbonGroup.Command>
<r:RibbonCommand LabelTitle="RibbonButton"/>
</r:RibbonGroup.Command>
<r:RibbonButton x:Name="RibbonButton1" Command="{Binding Path=SampleCommand}"/>
</r:RibbonGroup>
</r:RibbonTab.Groups>
</r:RibbonTab>
</r:Ribbon>
<Border Name="PageBorder" Grid.Row="0" Grid.Column="1">
<Frame Name="pageFrame" Source="FirstPage.xaml" />
</Border>
</DockPanel>
</Page>
Page1ViewModel.cs:
RelayCommand _sampleCommand;
public ICommand SampleCommand
{
get
{
// create command ??
return _sampleCommand
}
}
page1.xaml.cs:
Page1ViewModel pageViewModel;
//When page loads
this.DataContext = pageViewModel;
