I write my app without using Shell. So I created my own Window using IDialogService and opened in one of my modules. As far, as I am concerned, Region Manager is attached to Shell, but due to the fact I don't have it, region manager doesn't work when I try to navigate from one view to another.
I know that Region Navigation works fine with the shell (I tested it) and the same code stops working when I substitute the shell with IDialogService.
Here is what I have
<Window x:Class="TechDocs.Views.MainSettingsWindowView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:prism="http://prismlibrary.com/"
prism:ViewModelLocator.AutoWireViewModel="True"
mc:Ignorable="d"
Title="MainSettingsWindow" Height="400" Width="750">
<Grid>
</Grid>
</Window>
Content for the first region. When I click the button, it should navigate to the second region.
<UserControl x:Class="TechDocs.Views.SettingsView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:prism="http://prismlibrary.com/"
prism:ViewModelLocator.AutoWireViewModel="True"
mc:Ignorable="d"
d:DesignHeight="450" d:DesignWidth="800">
<Grid>
<Button Command="{Binding NodeSelectedCommand}" Name="Button"/>
<ContentControl prism:RegionManager.RegionName="region"/>
</Grid>
</UserControl>
In module I connect my root window with UserControl which holds the button and Content control for the second region.
public class SettingsModule : IModule
{
protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
var dialogService = _containerProvider.Resolve<IDialogService>();
containerRegistry.RegisterDialog<MainSettingsWindow>("MyWindow");
containerRegistry.RegisterDialog<SettingsView>("customView");
containerRegistry.RegisterForNavigation<MyView>();
dialogService.Show("customView");
}
}
And when I click the button I get in this code
public void SelectedNode()
{
regionManager.RequestNavigate("region", "MyView");
}
RequestNavigate doesn't give any exceptions, but still nothing appears on the screen. Could you please explain how I should register region manager with my window?
CodePudding user response:
Try to initialize the region manager explicitly in your custom window using the static methods below:
RegionManager.SetRegionName(cc, "region");
RegionManager.SetRegionManager(cc, regionManager);
XAML:
<ContentControl x:Name="cc" prism:RegionManager.RegionName="region"/>
