How do I access TextBox here I want to have the cursor focus on end of the textbox for that I have to have access to the textbox. How can it be done? Should It be done from code behind or from ViewModel?
I have tried TileNameTextBox.CaretIndex = TileNameTextBox.Text.Length;
and TileNameTextBox.Focus();
It is not working as I cannot access TileNameTextBox in code behind directly.
The DataContext set in code behind is like
DataContext = new ViewModel();

Does anyone know why this is?

You have set twice the window style here:
<Window.Style>
<Style TargetType="{x:Type Window}">
<Setter Property="Background" Value="{StaticResource WindowBrush}"/>
</Style>
And here:
WindowStyle="None"
I'm not close to a VS right now but it seems to be the problem.

Add Controllers to <Style> from Code-Behind (WPF)

I'm a beginner in WPF. It's hard as hell just so you know!
ok, i have a little style for my application (Actually i copied it, and really don't know whats happening in the middle so...)
i wanted to add some Hyperlinks and Buttons to header of application. so i edited the style and added those from there.
but now i want to change content of those from code-behind, but as you already know that's not happening!
This is my style in Application.Resources:

so i don't know how change content of Hyperlinks or even i could replace them with Button if that is necessary. just tell me how i could change those content. of course i have to say i tried FindResource but couldn't find that Hyperlinks or Buttons. Thanks in advance guys.

try this:
1. create a new WpfApplication project
2. remove MainWindow.xaml
3. add pages: startup.xaml, page1.xaml or more, and set diff background
4. change StartupUri="startup.xaml" in App.xaml
5. add NavigationWindow Style in App.xaml
<Style TargetType="{x:Type NavigationWindow}">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}"/>

Undeclared namespace

I've been trying so hard to find an external package to make my WPF Apps in VS 2010 Express Edition look like Metro UI but this version does not support it, so I found this thread: Making WPF applications look Metro-styled, even in Windows 7? (Window Chrome / Theming / Theme) in which the user creates an own Theme. I have tried to adapt his code to my App (namespace WpfApplication1 and window MainWindow, as it is set by default) but I get an error at this part:
<Style x:Key="MainWindowStyle" TargetType="WpfApplication1:MainWindow">
Where it says that WpfApplication1 is an undeclared namespace.
I don't know why this happens since the namespace has the following shape:
namespace WpfApplication1
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
}
}
And this is the whole code from this other guy adapted to my workspace:

Any ideas where it might be failing? Thanks!

When it says the namespace is not declared, it means that is not declared inside XAML. To declare it in XAML you use xmlns:, append the short name and then define the actual namespace, something like this:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:WpfApplication1="clr-namespace:WpfApplication1"
Title="MainWindow" Height="150" Width="350"
>
You can look at above, there are 3 declared namespaces, I added the one you missed and should fix your problem.
Of course you should use some short name instead.

WPF Layout Discrepancy Between Design and Runtime

I have used the answer to this question as the basis for styling an app I am building.
All looks good in design mode, I get the following:
But at runtime I get a large gap above my content, which in this case is a MediaElement:
The code for my MainWindow is:
<local:MyWindow x:Class="DebriefSuite.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:DebriefSuite"
Height="439.091" Width="600"
Style="{DynamicResource MyWindowStyle}"
WindowStyle="None">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="6*"/>
<RowDefinition Height="1*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="6*"/>
<ColumnDefinition Width="2*"/>
</Grid.ColumnDefinitions>
<Grid Grid.Row="0" Grid.Column="0">
<MediaElement Name="meVideo" Height="Auto" Width="Auto" IsMuted="True"/>
</Grid>
</Grid>
</local:MyWindow>
The code Resource code in my App.xaml is as in the linked question, but I will include it anyway:

Can anyone point me in the right direction as to where this formatting difference is coming from?
Many thanks.

You are seeing the box filling up the bigger space in the design, because thats the maximum size MediaElement can take up. But your actual image is smaller than the size allocated for the MediaElement contro, so it appears smaller at runtime.
So if you want the image to fill up the space try using its stretch property as required. Refer here for example: MediaElement.Stretch Property
