map shape to another button

<Path Data="M0.5,0 L0.5,1 M0,0.5 L1,0.5"
StrokeThickness="4"
Stretch="Fill"
Stroke="Blue" />
This will draw a plus sign on a button if the button is the only thing in window,
but how can one map the path to this button?
<ControlTemplate x:Key="BT_SIGN" TargetType="{x:Type Button}">
<Grid Cursor="None" Margin="0,0,1.333,0">
<Grid.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="Black" Offset="0"/>
<GradientStop Color="#FF1E8CF3" Offset="1"/>
</LinearGradientBrush>
</Grid.Background>
</Grid>
</ControlTemplate>
<Button
Grid.Column="3"
HorizontalAlignment="Left"
Height="44.8"
Width="75.2"
Margin="22.32,24.6,0,0"
VerticalAlignment="Top"
Template="{DynamicResource BT_SIGN}">
</Button>

Try this, i.e. add a <ContentPresenter /> to the template and set the Content property to your Path:
<ControlTemplate x:Key="BT_SIGN" TargetType="{x:Type Button}">
<Grid Cursor="None" Margin="0,0,1.333,0">
<Grid.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="Black" Offset="0"/>
<GradientStop Color="#FF1E8CF3" Offset="1"/>
</LinearGradientBrush>
</Grid.Background>
<ContentPresenter />
</Grid>
</ControlTemplate>
<Button
Grid.Column="3"
HorizontalAlignment="Left"
Height="44.8"
Width="75.2"
Margin="22.32,24.6,0,0"
VerticalAlignment="Top"
Template="{DynamicResource BT_SIGN}">
<Path Data="M0.5,0 L0.5,1 M0,0.5 L1,0.5"
StrokeThickness="4"
Stretch="Fill"
Stroke="Blue" />
</Button>

Just set the Path of that specific button inside the button markup.
<Button
Grid.Column="3"
HorizontalAlignment="Left"
Height="44.8"
Width="75.2"
Margin="22.32,24.6,0,0"
VerticalAlignment="Top"
Template="{DynamicResource BT_SIGN}">
<Path Data="M0.5,0 L0.5,1 M0,0.5 L1,0.5"
StrokeThickness="4"
Stretch="Fill"
Stroke="Blue" />
</Button>

wpf grid background with image brush and visual brush combined

I am trying to set an image as a background of my window. I want to apply a gradient opacity mask over the window, and have the image tiled. So far, I can get either or, but not both. Here's my lame attempt at this:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height = "40*" />
<RowDefinition Height="133*"/>
</Grid.RowDefinitions>
<Grid.Resources>
<Image x:Key="myImage" Source="/GrimshawRibbon;component/Resources/GeometricBackground.png">
<Image.OpacityMask>
<LinearGradientBrush EndPoint = "0.5,0" StartPoint="0.5,1">
<GradientStop Color = "#00000000" Offset="0.6"/>
<GradientStop Color = "#FF000000" Offset="1"/>
</LinearGradientBrush>
</Image.OpacityMask>
</Image>
<ImageBrush x:Key="imageBrush" ImageSource="/GrimshawRibbon;component/Resources/GeometricBackground.png" TileMode="Tile" ViewportUnits="Absolute" Viewport="0,0,800,800"/>
<VisualBrush x:Key="myBrush" Visual="{StaticResource myImage}" Stretch="None" TileMode="Tile"/>
</Grid.Resources>
<DockPanel LastChildFill = "False" Grid.RowSpan="2" Background="{StaticResource imageBrush}"/>
<ContentControl x:Name="MainContentControl" Content="{Binding CurrentPageViewModel}" Margin="10" Grid.Row="1"/>
<Button x:Name="btnCancel" Content="Close" Margin="0,0,90,10" HorizontalAlignment="Right" Width="75" Height="36" VerticalAlignment="Bottom" Command="{Binding CloseWindowCommand, Mode=OneWay}" CommandParameter="{Binding ElementName=win}" Grid.Row="1"/>
<Button x:Name="button" Content="?" Margin="0,0,170,10" Height="36" VerticalAlignment="Bottom" HorizontalAlignment="Right" Width="36" Command="{Binding NavigateToHelpCommand, Mode=OneWay}" Grid.Row="1"/>
<Label x:Name="label" Content="Some label" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" FontWeight="Bold" FontSize="14"/>
<TextBlock x:Name="textBlock" HorizontalAlignment="Left" Margin="10,39,0,0" TextWrapping="Wrap" Text="Some tool description that is not too long. It would be good to keep it under two sentences." VerticalAlignment="Top" Height="36" Width="272"/>
</Grid>

You may assign the DockPanel's OpacityMask:
<DockPanel Grid.RowSpan="2" Background="{StaticResource imageBrush}">
<DockPanel.OpacityMask>
<LinearGradientBrush EndPoint="0.5,0" StartPoint="0.5,1">
<GradientStop Color="#00000000" Offset="0.6"/>
<GradientStop Color="#FF000000" Offset="1"/>
</LinearGradientBrush>
</DockPanel.OpacityMask>
</DockPanel>
Or probably just use a Rectangle for the background image:
<Rectangle Grid.RowSpan="2" Fill="{StaticResource imageBrush}">
<Rectangle.OpacityMask>
<LinearGradientBrush EndPoint="0.5,0" StartPoint="0.5,1">
<GradientStop Color="#00000000" Offset="0.6"/>
<GradientStop Color="#FF000000" Offset="1"/>
</LinearGradientBrush>
</Rectangle.OpacityMask>
</Rectangle>

Why can't I see the menu I created?

So I'm creating a small wpf application for fun, and I want it to have a menu. I created the menu and what not, but when I run the program the menu doesn't show up at all. The code for the menu is currently:
<Window x:Class="TBA_Alpha.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Grid>
<PasswordBox x:Name="tbPsw" HorizontalAlignment="Left" Margin="214,143,0,0" VerticalAlignment="Top" Width="133" SelectionBrush="Black" Background="White">
<PasswordBox.BorderBrush>
<LinearGradientBrush EndPoint="0,20" MappingMode="Absolute" StartPoint="0,0">

</LinearGradientBrush>

</PasswordBox>

<TextBlock HorizontalAlignment="Left" Margin="214,122,0,0" TextWrapping="Wrap" Text="Your Password:" VerticalAlignment="Top"/>
<Menu HorizontalAlignment="Left" Height="25" VerticalAlignment="Top" Width="43" BorderThickness="1">

<MenuItem Header=" User " Click="newUser"/>
</MenuItem>
</Menu>
</Grid>
any help whatsoever would be largely appreciated thank-you.
Edit: added the entire XAML code for the wpf, where the menu is near the end of the code
Edit: after removing all of the additional stuff and leaving only the headers, still experiencing the same problem
Edit: Tried the code in a different clean project and it worked, thank-you

The problem is that most of your controls use a Magrin attribute to separate themselves, rather than the functionality of the Grid. Since none of them specify the attached properties Grid.Row, they're all in the same row. Since Menu doesn't specify a Margin, it's at the top of the Grid and thus overlapping your other controls.
Try using actual grid rows

Wait until Code behind WPF Animation is Completed

I am building an application that looks like RoboZZle , but I have a problem:(the programming language in the answer is not important : C# or VB.NET)
I have three animations in the code behind which look like this:
Private Sub btngo_Click(sender As Object, e As RoutedEventArgs) Handles btngo.Click
go_stright()
go_stright()
go_stright()
go_stright()
End Sub
Private Sub go_stright()
Dim da As New DoubleAnimation()
Dim tt As New TranslateTransform()
da.From = offsety
offsety -= 50
da.To = offsety
da.Duration = New Duration(TimeSpan.FromSeconds(1))
tt.BeginAnimation(TranslateTransform.YProperty, da)
End Sub
This is the problem: when I click the "btngo" button, the last animation (4th go_stright) has animation effect. I need to wait until one animation is completed before the next one starts.
How can I do this?
Note: In roboZZle , the user with his algorithm moves sprite to destination and sprite movement isn't pre-defined.
i am a newbie in WPF.
Update: I have no Story Boards.

You can add a completed event on the animation in which you will check how many steps you have to make and perform them if you're not there yet:
Private Sub btngo_Click(sender As Object, e As RoutedEventArgs) Handles btnGo.Click
PerformNextAction(actions(0))
End Sub
Private Sub go_stright()
Dim da As New DoubleAnimation(offsety, offsety - 50, New Duration(TimeSpan.FromSeconds(1)))
offsety -= 50
Dim tt As New TranslateTransform()
AddHandler da.Completed, AddressOf AnimationCompleted
tt.BeginAnimation(TranslateTransform.YProperty, da)
End Sub
Private Sub AnimationCompleted(sender As Object, e As EventArgs)
If actionCounter < 4 Then
actionCounter += 1
PerformNextAction(actions(actionCounter))
End If
End Sub
Private Sub PerformNextAction(ByVal action As Action)
Select Case action
Case MainWindow.Action.GoStraight
go_stright()
Case MainWindow.Action.RotateLeft
rotate_left()
Case MainWindow.Action.RotateRight
rotate_right()
End Select
End Sub
Don't forget this one too:
Private goStraightCounter As Integer
This one will keep track of your progress (how many times you need to keep calling the method).
Edit
To answer your comment, you could make an enum like this:
Public Enum Action
GoStraight
RotateRight
RotateLeft
End Enum
In the application you linked, the user has to make a list of action, so you could make that list a list of action (see enum). Then, instead of calling "go_stright", you just look at the next entry in the action list and call the method that goes for that action.
Edit 2:
To go deeper on actions, make a list of actions:
Public actions As ObservableCollection(Of Action)
So if the user has 5 actions he picked, you would have 5 enumactions in your list. So the list might look like this for example: GoStraight, RotateLeft, GoStraight, RotateLeft, GoStraight. In the animationcompleted event, instead of just calling the go_straight, you could implement a select case that checks which method you have to call (see updated code above). I just guessed how your go left and go right methods are called, so you might have to change those names.

Register an new EventHandler for the Completed Event in C#:
public MainWindow()
{
InitializeComponent();
System.Windows.Media.Animation.DoubleAnimation ani = new System.Windows.Media.Animation.DoubleAnimation();
ani.Completed += new EventHandler(ani_Completed);
}
void ani_Completed(object sender, EventArgs e)
{
throw new NotImplementedException();
}

I had the same problem.. Wire up a completed event and a property, then use a method that clears the dispatcher thread before returning..
// at the end of animation routine
progressTransition.Completed += new EventHandler(progressFlyOut_Completed);
progressTransition.Begin(ControlElement);
// allow animation to complete

Silverlight change button text

I have a button with multiple contetnt. I want to change it's text when the button is clicked.
XAML:
<Button HorizontalAlignment="Left" Height="114" Margin="33,58,0,0" VerticalAlignment="Top" Width="224" Style="{StaticResource GlassButtonStyle}" FontSize="26.667" Click="Button_Click_1" Name="button1">
<StackPanel Orientation="Horizontal">
<Rectangle Height="69" Stroke="Black" Width="69">
<Rectangle.Fill>
<LinearGradientBrush EndPoint="0.004,1.044" StartPoint="0.739,0.25">
<GradientStop Color="Black" Offset="0"/>
<GradientStop Color="White" Offset="1"/>
</LinearGradientBrush>
</Rectangle.Fill>
</Rectangle>
<ContentPresenter Content="Clicke me" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</StackPanel>
</Button>
C# code:
button1.Content = "Hello world";
This makes the rectangle disappear, though I want only to change the text. How can I do this?

You need to modify the Control Template of Button to show your rectangle all the time.
<Button HorizontalAlignment="Left" Height="114" Margin="33,58,0,0" VerticalAlignment="Top" Width="224" Style="{StaticResource GlassButtonStyle}" FontSize="26.667" Click="Button_Click_1" Name="button1" Content="Click Me">
<Button.Template>
<ControlTemplate>
<StackPanel Orientation="Horizontal">
<Rectangle Height="69" Stroke="Black" Width="69">
<Rectangle.Fill>
<LinearGradientBrush EndPoint="0.004,1.044" StartPoint="0.739,0.25">
<GradientStop Color="Black" Offset="0"/>
<GradientStop Color="White" Offset="1"/>
</LinearGradientBrush>
</Rectangle.Fill>
</Rectangle>
<ContentPresenter Content="{TemplateBinding Content}" />
</StackPanel>
</ControlTemplate>
</Button.Template>
</Button>
