Я пытаюсь найти способ инициировать закрытие активного DialogHost из кода, но не смог найти правильный синтаксис.Я думаю, что основной проблемой является доступ к DialogHost из класса за пределами кода MainWindow.
Полный текст моего XAML:

<Button Name="CircleButton" Margin="0 50 0 0" Style="{StaticResource MaterialDesignFloatingActionButton}"
Command="{Binding SaveComand}" IsHitTestVisible="False"
materialDesign:ButtonProgressAssist.IsIndicatorVisible="{Binding IsSaving}"
materialDesign:ButtonProgressAssist.Value="{Binding SaveProgressButton}">
<materialDesign:PackIcon Height="24" Width="24" Foreground="White">
<materialDesign:PackIcon.Style>
<Style TargetType="materialDesign:PackIcon" BasedOn="{StaticResource {x:Type materialDesign:PackIcon}}">
<Setter Property="Kind" Value="CloudSync" />
<Style.Triggers>
<DataTrigger Binding="{Binding IsSaveComplete}" Value="True">
<Setter Property="Kind" Value="Check" />
<DataTrigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Opacity" From="0" To="1" Duration="0:0:0.8" />
</Storyboard>
</BeginStoryboard>
</DataTrigger.EnterActions>
</DataTrigger>
</Style.Triggers>
</Style>
</materialDesign:PackIcon.Style>
</materialDesign:PackIcon>
</Button>
</StackPanel>
</Button.CommandParameter>
</Button>
</StackPanel>
</Grid>
</materialDesign:DialogHost>
И код изкоторый мне нужно инициировать закрытие (это в модели представления, а не в коде MainWindow):
private async void progressTimerTick(object sender, EventArgs e)
{
if (progress < 100 && cycles < 2)
{
if (progress == 99)
{
cycles++;
progress = 0;
}
IsSaveComplete = false;
IsSaving = true;
progress++;
SaveProgressButton = progress;
}
else
{
IsSaveComplete = true;
IsSaving = false;
progressTimer.Enabled = false;
SaveProgressButton = 0;
await PutTaskDelay();
//Close dialog here
}
}
