How to get the current usercontrol inside a ContentControl in MainWindow? (MVVM) - c#

I wanna know if it is posible the get the current usercontrol inside a contentcontrol of a mainview. Here's my xaml MainWindow
<Window x:Class="MatchGameModified.MainWindow"
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:local="clr-namespace:MatchGameModified"
xmlns:viewModels="clr-namespace:MatchGameModified.ViewModels"
xmlns:views="clr-namespace:MatchGameModified.Views"
mc:Ignorable="d"
Title="MainWindow" Height="600" Width="450"
ResizeMode="NoResize" WindowStartupLocation="CenterScreen">
<!-- ViewModel revolver -->
<Window.Resources>
<DataTemplate DataType="{x:Type viewModels:StartGameViewModel}">
<views:StartGameView/>
</DataTemplate>
<DataTemplate DataType="{x:Type viewModels:GameViewModel}">
<views:GameView/>
</DataTemplate>
</Window.Resources>
<!-- Bind DataContext via XAML-->
<Window.DataContext>
<viewModels:MainViewModel/>
</Window.DataContext>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Text="{Binding PlayerName}" FontSize="36" HorizontalAlignment="Center" VerticalAlignment="Center"/>
<Grid Grid.Row="1" x:Name="MainContent">
<Border BorderThickness="2" BorderBrush="Black">
<ContentControl x:Name="ContentControl" Content="{Binding CurrentViewModel}"/>
</Border>
</Grid>
</Grid>
I know it is posible to get the mainwindow instance from a usercontrol, but I want to get a usercontrol element.

you can add event handler to Loaded event of each view
<DataTemplate DataType="{x:Type viewModels:StartGameViewModel}">
<views:StartGameView Loaded="ViewLoaded"/>
</DataTemplate>
<DataTemplate DataType="{x:Type viewModels:GameViewModel}">
<views:GameView Loaded="ViewLoaded"/>
</DataTemplate>
and get UserControl from sender argument:
private void ViewLoaded(object sender, RoutedEventArgs e)
{
var view = sender as UserControl;
}

Windows 10 universal app UserControl in stackpanel

I need to place a custom UserControl into a Stackpannel.
I have this UserControl:
<UserControl
x:Class="ScannerApp.Custom_Controls.LocationAndQuantity"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:ScannerApp.Custom_Controls"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
d:DesignHeight="20"
d:DesignWidth="400">
<Grid Background="White">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100*"/>
<ColumnDefinition Width="80*"/>
<ColumnDefinition Width="100*"/>
</Grid.ColumnDefinitions>
<Border x:Name="border" Background="Red" BorderThickness="1" HorizontalAlignment="Left" Height="20" VerticalAlignment="Top" Width="143">
<TextBlock x:Name="locationTxt" Text="location" HorizontalAlignment="Center"></TextBlock>
</Border>
<TextBlock x:Name="quantityTxt" Text="quantity" Grid.Column="2" HorizontalAlignment="Center" TextWrapping="Wrap" VerticalAlignment="Top"/>
</Grid>
</UserControl>
and a page with stackpanel
<Page
x:Class="ScannerApp.FindPN___STEP2"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

mc:Ignorable="d">
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
...
<StackPanel>
<!--here I want to place the userControls-->
</StackPanel>
</Grid>
</Page>
I tried some sollutions like <controls: ...> //this could not be found by intellisense even or
<my:UserControlName Grid.Column="2" Grid.Row="2" ... />
<Window ...
xmlns:my="clr-namespace:AssemblyName"
...
/>
but I don't have the Window here... I tried to place something similar into the Page, but I don't really know what to type in there.
As said in comments, you've to fix your XAML. If you want to use custom controls you've to tell the compiler where the controls come from.
In case you Controls namespace is
ScannerApp.Custom_Controls
You've to write the Page XAML as
<Page
x:Class="ScannerApp.FindPN___STEP2"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:ScannerApp.Custom_Controls" <!--FIXED HERE-->
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
...
<StackPanel>
<local:NameOfYourControl x:Name="MyNewControl" /> <!--Properties can be added-->
</StackPanel>
</Grid>
</Page>

XML DataTemplate Binding MultiLayer UserControl

I'm building an app in which I have created a UserControlthat has a second UserControl inside of it.
Here is the first UserControl:
<UserControl x:Class="TasksMonitor.CustomControls.TaskCardBtn"
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:local="clr-namespace:TasksMonitor.CustomControls"
mc:Ignorable="d"
Name="TaskCardBtnCustomControl"
d:DesignHeight="300" d:DesignWidth="300">
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="../CustomButtonsStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
<Style TargetType="ToolTip"></Style>
</ResourceDictionary>
</UserControl.Resources>
<Button Click="OnButtonClick" Style="{DynamicResource FlatCntrlBtn}">
<Grid Width="{Binding ActualWidth, ElementName=TaskCardBtnCustomControl}" VerticalAlignment="Center" HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1"/>
<ColumnDefinition Width="15"/>
<ColumnDefinition Width="10"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="35"/>
</Grid.RowDefinitions>
<Canvas Margin="4,10,0,0" Grid.Column="1">
<Ellipse Width="15" Height="15" Fill="{Binding Path=StatusColor, ElementName=TaskCardBtnCustomControl, FallbackValue=#FFFFFF}"/>
</Canvas>
<TextBlock VerticalAlignment="Center" x:Name="BtnTitle" Grid.Column="3" Text="{Binding Path=BtnText, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"/>
</Grid>
</Button>
</UserControl>
That UserControl is inside of this UserControl:
<UserControl x:Class="TasksMonitor.CustomControls.TaskCardUserControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:cc="clr-namespace:TasksMonitor.CustomControls"
Name="TaskCardUC"
mc:Ignorable="d"
Margin="5"
d:DesignHeight="35" d:DesignWidth="300">
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary x:Name="Icons" Source="../Resources/Icons.xaml" />
</ResourceDictionary.MergedDictionaries>
<ut:StatusToColorConverter x:Key="StatusToColor"/>
</ResourceDictionary>
</UserControl.Resources>
<Grid Width="auto">
<Grid Background="#2B2B2B">
<Grid.RowDefinitions>
<RowDefinition Height="35"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid Grid.Row="0">
<cc:TaskCardBtn StatusColor="{Binding TskStatus, Converter={StaticResource StatusToColor}}" BtnText="{Binding Path=StuffYeah, ElementName=TaskCardUC}" x:Name="ExpandCollapseBtn" BtnClick="GridContentControl_Expand"/>
</Grid>
<Grid Grid.Row="1" Background="#2B2B2B" Name="GridContent" >
<UserControl Margin="10" Loaded="GridContentControl_Loaded">
</UserControl>
</Grid>
</Grid>
</Grid>
</UserControl>
The second UserControl or Parent UserControl is being used in a DataTemplate:
<Grid.Resources>
<DataTemplate x:Key="itemTemplate">
<cc:TaskCardUserControl StuffYeah="{Binding BtnTxt}"/>
</DataTemplate>
</Grid.Resources>
When I set the Bind to BtnTxt as illustrated in the DataTemplate above it does not work and says that it can't find 'BtnTxt' in object TaskCardUserControl. I feel that this is a binding issue as I have a property from the first UserControl bound to the parent property and then that parent property bound to the DataTemplate. I'm very new to DataTemplates and UserControl in general, would someone be able to point me in the correct direction?
Thanks in advance.
I figured this out...I was setting this.DataContext = this in the code which was actually old code. Once I commented this out everything works as it should. Thanks for the help.

TextBlock not Wrapping Silverlight application

I have a TextBlock that is not wrapping and thinks it has an infinite width. I have tried to bind it to the actualWidth of the Grid and/or UserControl, but both widths come as more than 8000. I have tried disabling the HorizontalScrollBarVisibility in the parent view, but that does not work either. I have also read all question in SO that are related to mine and none of the suggestions seems to work.
<UserControl x:Class="Civica.UI.CurrentUserMenu.Views.ClassName"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

mc:Ignorable="d"
d:DesignHeight="300"
d:DesignWidth="1200">
<UserControl.Resources>
<ResourceDictionary>
<SolidColorBrush x:Key="SeparatorBrush" Color="#66848484" />
</ResourceDictionary>
</UserControl.Resources>
<Grid>
<ScrollViewer x:Name="Viewer" BorderThickness="0" Grid.Column="1" Grid.Row="1" Margin="0,0,0,0" Padding="0"
VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled"
HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch">
<Grid Background="White" HorizontalAlignment="Left" x:Name="UserControl">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Border BorderThickness="0,0,0,1" BorderBrush="{StaticResource SeparatorBrush}" Grid.Row="0">
<TextBlock Text="Text" Margin="0" FontWeight="Black" />
</Border>
<TextBlock Margin="5" Text="{Binding TextProperty}" TextWrapping="Wrap" Grid.Row="1"/>
</Grid>
</ScrollViewer>
</Grid>
</UserControl>
EDIT:
This is the code for the parent view:
<UserControl x:Class="Civica.UI.Ribbon.Views.ViewName"
d:DataContext="{d:DesignInstance Type=ViewMOdelName}"
d:DesignHeight="120"
d:DesignWidth="600"
mc:Ignorable="d">
<Grid ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<telerik:RadRibbonView x:Name="RadRibbon"
Title="Title"
ApplicationButtonContent="Content"
ApplicationMenu="{Binding PropertyName}"
ApplicationName="{Binding PropertyName}"
MinimizeButtonVisibility="Visible"
SelectionChanged="SelectionChanged" ScrollViewer.HorizontalScrollBarVisibility="Disabled"/>
</Grid>
</UserControl>
It is the RadRibbonView that contains the first view.
The issue was a style that was being applied by the parent view and specifically a Telerik object. The solution was to find that style, decompile it and copy is to one of our files and change a scrollviewer to a border.

Cannot bind to TabItem DataContext from the TabItem Content in Silverlight

I have a TabItem that has it's DataContext set to a ViewModel.
The header is set to a header View and the Content is set to an item view
However this Binding from the item view just doesn't work
<TextBox Margin="0" Grid.Column="0" Grid.Row="0" Text="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=sdk:TabItem, AncestorLevel=1}, Path=DataContext.Job.SourceCode, Mode=TwoWay}"/>
yet this binding
<TextBlock Text="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=sdk:TabItem, AncestorLevel=1}, Path=DataContext.Job.Name}"/>
which is in the header view works fine.
I've even tried putting the TextBlock from the Header into the Item and setting the Content to a new HeaderView. No matter what I try I can't get the bindings from the Content to work even though the header binding works fine
Can anyone explain?
Adding the full Views as requested first the Item
