WPF Grid Items and Right Aligned Text - wpf

Question

I have a WPF form where I'm trying to make a simple input form. Two labels, two textboxes, and a "submit" button. I have the layout pretty good, the only thing that I can't get is for my "Labels" to be right aligned inside their cells. I have tried both TextAlign="Right" and HorizontialAlign="Right", that moves the text ALL the way over, overlaying my textbox, not just moving inside the cell. Below is the XAML for the window.
<Window x:Class="MyWebKeepAliveDesktop.Login"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MyWebKeepAlive Desktop - Login" WindowStyle="None" AllowsTransparency="true" Height="200" Width="400" >
<Border Background="#50FFFFFF" CornerRadius="7" BorderBrush="{StaticResource WindowFrameBrush}" BorderThickness="2,0,2,2">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="30" />
<RowDefinition/>
</Grid.RowDefinitions>
<Border Background="{StaticResource WindowFrameBrush}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
CornerRadius="5,5,0,0" Margin="-1,0,-1,0" MouseLeftButtonDown="DragWindow">
<Grid>
<TextBlock Foreground="White" FontWeight="Bold" VerticalAlignment="Center" Margin="10,2,10,2"
Text="MyWebKeepAlive Desktop Login"/>
<Button Content="X" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="5" FontSize="7"
Width="15" Height="15" Padding="0" Command="ApplicationCommands.Close"/>
</Grid>
</Border>
<Grid Grid.Row="1" Width="350" Height="130" HorizontalAlignment="Center" VerticalAlignment="Center">
<Grid.RowDefinitions>
<RowDefinition Height="35" />
<RowDefinition Height="25" />
<RowDefinition Height="25" />
<RowDefinition Height="10" />
<RowDefinition Height="30" />
</Grid.RowDefinitions>
<TextBlock TextAlignment="center" Text="Please provide your username/password that is used on the MyWebKeepAlive.com site to login." TextWrapping="Wrap" Grid.Row="0" Grid.ColumnSpan="2" />
<TextBlock Text="Username" FontWeight="Bold" Grid.Row="1" Grid.Column="0"/>
<TextBox Name="txtUsername" Width="150" Grid.Row="1" Grid.Column="1" />
<TextBlock Text="Password" FontWeight="Bold" Grid.Row="2" />
<TextBox Name="txtPassword" Width="150" Grid.Row="2" />
<Button Name="btnLogin" Grid.Row="4" Grid.ColumnSpan="2">
<TextBlock Text="Login" />
</Button>
</Grid>
</Grid>
</Border>
</Window>

Answer 1

Your grid only has one column as written. It will need two to support your setting of Grid.Column=1 for the text boxes. Thus, you need to add a <ColumnDefinitions> block. With the XAML the way it is now, WPF just throws both controls into the same column, hence the behavior you are seeing.

Answer 2

Here's what I came up with. Just learning WPF myself. As PeterAllenWebb mentioned, your main issue is you are missing the ColumnDefinitions. I also added the TextAlignment="Right" attributes to the two TextBlocks.
<Grid Grid.Row="1" Width="350" Height="130" HorizontalAlignment="Center" VerticalAlignment="Center">
<Grid.RowDefinitions>
<RowDefinition Height="35" />
<RowDefinition Height="25" />
<RowDefinition Height="25" />
<RowDefinition Height="10" />
<RowDefinition Height="30"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock TextAlignment="center" Text="Please provide your username/password that is used on the MyWebKeepAlive.com site to login." TextWrapping="Wrap" Grid.Row="0" Grid.ColumnSpan="2" />
<TextBlock Text="Username" TextAlignment="Right" FontWeight="Bold" Grid.Row="1" Grid.Column="0"/>
<TextBox Name="txtUsername" Width="150" Grid.Row="1" Grid.Column="1" />
<TextBlock Text="Password" TextAlignment="Right" FontWeight="Bold" Grid.Row="2" />
<TextBox Name="txtPassword" Width="150" Grid.Row="2" Grid.Column="1"/>
<Button Name="btnLogin" Grid.Row="4" Grid.ColumnSpan="2">
<TextBlock Text="Login" />
</Button>
</Grid>
