I made an mvvm project in WPF.
However, I get an error in my MainWindow.xaml, saying I can't put a window in a style...
This is my MainWindow.xaml:
<Window x:Class="DataValidation.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Title="MainWindow" Height="350" Width="525">
<Window.DataContext>
<vm:AccountVM/>
</Window.DataContext>
<Window.Resources>
<DataTemplate DataType="{x:Type vm:AccountVM}">
<v:HomePage/>
</DataTemplate>
</Window.Resources>
<Grid>
<ContentControl Content="{Binding CurrentPage}"/>
</Grid>
</Window>
the error occurs on <v: HomePage>
In my HomePage.xaml I don't use the <window> tags ... So I have no idea what the actual problem could be:

How do i bind the Y-coordinates to a slider and the width to a combobox so when u change the slider it looks like its crawling down the left side.
<Window x:Class="Grafik.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="80*"/>
<ColumnDefinition Width="30*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="1" Text="Y-Position des Objekts"/>
<Slider Name="position" Minimum="0" Maximum="500" Canvas.Left="20" Grid.Column="1"/>
<ComboBox x:Name="breite" Grid.Column="1" HorizontalAlignment="Left" Margin="5,40,0,0" VerticalAlignment="Top" Width="136">
<ComboBoxItem >15</ComboBoxItem>
<ComboBoxItem >30</ComboBoxItem>
<ComboBoxItem >45</ComboBoxItem>
<ComboBoxItem >60</ComboBoxItem>
</ComboBox>
<Canvas>
<Rectangle Fill="Red" Width="10" Height="10" Canvas.Top="{Binding ElementName=position, Path=Value}"/>
</Canvas>
</Grid>
The binding to the slider's value works for me when I use your code.
You can bind directly to the combobox' value if you put real numbers in there. Otherwise you have to use appropriate converters.
<Window
...
xmlns:system="clr-namespace:System;assembly=mscorlib"
>
<ComboBox ...>
<system:Double>15</system:Double>
...
</ComboBox>
<Rectangle ... Width={Binding SelectedItem ElementName=breite}/>
You might want to preselect a width with:
<ComboBox ... SelectedIndex="0">
I have an image that is bigger than it's window container and it is placed in a ScrollViewer, however, the image does not scroll at all. I've tried putting the image in a container with no luck. What settings am I missing here? (I copied the code straight from MS, but they have it wrong)
Here's the code:
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:h="http://helixtoolkit.codeplex.com" x:Class="TileLayout"
Title="TileLayout" Height="1000" Width="845" WindowStartupLocation="CenterScreen" WindowStyle="ThreeDBorderWindow">
<StackPanel HorizontalAlignment="center" VerticalAlignment="Top">
<StackPanel Orientation="Horizontal" >
<TextBox x:Name="txtSourceFilePath" Width="500" Margin="10" Height="22" TextChanged="TextBox_TextChanged" Text="E:\projects\Test3D\SavedSnapshots\snapshot.png"/>
<Button x:Name="btnPickFile" Width="100" Margin="0,10,10,10" Content="Pick File" ></Button>
</StackPanel>
<ScrollViewer VerticalScrollBarVisibility="Auto" >
<Image x:Name="imgFinal" Source="SteelMotion_chevron2.png"/>
</ScrollViewer>
</StackPanel>
<Window

xmlns:h="http://helixtoolkit.codeplex.com" x:Class="TileLayout"
Title="TileLayout" Height="1000" Width="845" WindowStartupLocation="CenterScreen" WindowStyle="ThreeDBorderWindow">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="50"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<StackPanel Orientation="Horizontal" Height="50" HorizontalAlignment="Center" VerticalAlignment="Top" Grid.Row="0">
<TextBox x:Name="txtSourceFilePath" Width="500" Margin="10" Height="22" TextChanged="TextBox_TextChanged" Text=""/>
<Button x:Name="btnPickFile" Width="100" Margin="0,10,10,10" Content="Pick File" ></Button>
</StackPanel>
<ScrollViewer VerticalScrollBarVisibility="Auto" Grid.Row="1" >
<Image x:Name="imgFinal" Source="SteelMotion_chevron2.png" Width="768" Height="1408"/>
</ScrollViewer>
</Grid>
You need to specify the size of the ScrollViewer.
In this case ScrollViewer and Image are same size, so the scroll bar does not show.
