I am trying to set the HorizontalAlignment of a button to the the right, but the button will change position. can someone please tell me what i am doing wrong. Thanks everyone in advance.
here is what i have tried so far:
1). DockPanel.Dock="Right"
2). HorizontalAlignment="Right"
<DockPanel Grid.Row="1">
<TextBlock Width="{Binding ActualWidth, ElementName=CanColorBar}" >
<TextBlock.Style>
<Style TargetType="{x:Type TextBlock}">
<Setter Property="Background" Value="SkyBlue"/>
</Style>
</TextBlock.Style>
<InlineUIContainer>
<Button x:Name="btnAcceptMerge" Content="Accept Merge"/>
</InlineUIContainer>
<Run Text=" "/>
<InlineUIContainer>
<Button x:Name="btnCancel" Content="Cancel Merge" Click="btnCancel_Click"/>
</InlineUIContainer>
</TextBlock>
</DockPanel>
Your problem is that you have all your buttons inside the TextBlock. This is not a very optimal or good layout. Try this instead:
<DockPanel Grid.Row="1" Background="SkyBlue" Width="{Binding ActualWidth, ElementName=CanColorBar}">
<Button x:Name="btnAcceptMerge" Content="Accept Merge" DockPanel.Dock="Left"/>
<Button x:Name="btnCancel" Content="Cancel Merge" Click="btnCancel_Click" DockPanel.Dock="Right"/>
<TextBlock Text=""/>
</DockPanel>

This question already has answers here:
Virtualizing WPF Wrap Panel Issue
(3 answers)
Is there a virtualizing WrapPanel for WPF available? Commercial or free ones
(2 answers)
Virtualizing WrapPanel as ListView's ItemsTemplate
(3 answers)
Closed 4 years ago.
So no matter how hard I try I can't get virtualization in my view to work.
When I scroll through my Listbox, the items always keep populating from the top and carry on right to the bottom, rather than rendering what is on screen and just a bit above and bellow.
Any help would be very much appreciated.
Bellow is the code for the Viewbox. A point of note:
I am using a Viewbox inside a ListBox and a grid inside the ViewBox. This is because my items populate in a similar way to text with word warping turned on - it populates horizontally until the width, then moves on to the next line.
My items in the ListBox are scalable, and there position in the view changes dynamically depending on the scale size, whilst also, the TextBlocks text dose not scale.
Not sure if that effects virtualization in a way I am unaware.
If that is not clear, I apologise and am happy to answer any questions. Thanks for your time:

Here is my control template for the button style.
<StackPanel Orientation="Horizontal">
<Image x:Name="EmailImage" Source="../Images/btn__icon_savedisk.png" Height="17" Width="17" Stretch="None" RenderOptions.BitmapScalingMode="NearestNeighbor" />
<TextBlock x:Name="EmailImageTxt" Margin="20,0,20,0" Foreground="White" Text="{x:Static res:Localize.SAVE}" Background="{x:Null}" />
</StackPanel>
My problem is when I get mouse pointer over the area with the space between image and text button(image and text) is not selecting. I need to have mouse focus on all over the buttons.
Thank you for your help.
Set Background="Transparent" to stackpanel and it works as expected.
An control with no background is usually called as non-hittable in XAML terms. So it is must to set a background to make the object respond to hits.
<Button VerticalAlignment="Center" HorizontalAlignment="Center">
<Button.Template>
<ControlTemplate>
<StackPanel x:Name="stackpanel" Orientation="Horizontal">
<Image x:Name="EmailImage" Source="Black.jpg" Height="17" Width="17" Stretch="None" RenderOptions.BitmapScalingMode="NearestNeighbor" />
<TextBlock x:Name="EmailImageTxt" Margin="20,0,20,0" Foreground="Black" Text="gdfgdg}" Background="{x:Null}" />
</StackPanel>

<Trigger Property="IsMouseOver" Value="True">

So I'm adding my views directly to the TabControl's Items collection at runtime (instead of creating TabItems around them and addings those TabItems to TabControl). The views expose a property (wrapper around a ViewModel property of the same name) named HasChanges that I want to bind to TabItem's Header to show a Asterisk (*) sign to identify tabs with unsaved changes, just like VS does. I have already tried using DataTemplates but am having trouble accessing the view object in the DataTemplate. What's the correct way of doing this? Here's one of my several attempts:
<TabControl.ItemTemplate>
<DataTemplate DataType="UserControl">
<StackPanel Orientation="Horizontal" Margin="0" Height="22">
<TextBlock VerticalAlignment="Center" Text="{Binding HeaderText, RelativeSource={RelativeSource AncestorType=UserControl}}" />
<TextBlock Text="*" Visibility="{Binding HasChanges, RelativeSource={RelativeSource Mode=TemplatedParent}, Converter={StaticResource B2VConverter}}" />
</StackPanel>
</DataTemplate>
</TabControl.ItemTemplate>
Note that I'm trying two different binding methods for the two TextBlocks, none of which is working. My views inherit from UserControl and expose properties HasChanges and HeaderText.
OK. I solved it myself. For anyone else trying to implement a VS-like Close button and unsaved changes asterisk, here's the template:
<TabControl.ItemContainerStyle>
<Style TargetType="{x:Type TabItem}">
<Setter Property="HeaderTemplate" >
<Setter.Value>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0" Height="22">
<TextBlock VerticalAlignment="Center" Text="{Binding RelativeSource={RelativeSource AncestorType=TabItem}, Path=Content.HeaderText}" />
<TextBlock Text=" *" ToolTip="Has unsaved changes" Visibility="{Binding Content.DataContext.HasChanges, RelativeSource={RelativeSource AncestorType=TabItem}, Converter={StaticResource B2VConverter}}" />
<Button Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}" Width="18" Height="18"
Margin="6,0,0,0" Padding="0" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" HorizontalAlignment="Center"
Command="{Binding DataContext.TabClosingCommand, RelativeSource={RelativeSource AncestorType={x:Type Window}}}"
CommandParameter="{Binding RelativeSource={RelativeSource AncestorType=UserControl}}"
VerticalAlignment="Center" Focusable="False">
<Grid Margin="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Line StrokeThickness="3" StrokeStartLineCap="Round" StrokeEndLineCap="Round" Stroke="Gray" X1="1" Y1="1" X2="9" Y2="9" HorizontalAlignment="Center" VerticalAlignment="Center" />
<Line StrokeThickness="3" StrokeStartLineCap="Round" StrokeEndLineCap="Round" Stroke="Gray" X1="1" Y1="9" X2="9" Y2="1" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
</Button>
</StackPanel>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
</TabControl.ItemContainerStyle>
Results in an elegant drawing-based button with a flat-look. Your View must implement Boolean HasChanges and HeaderText properties, plus you need to define a BooleanToVisibilityConverter in your resources section, named B2VConverter.
I'm having a problem styling my ListBox selection background.
I used ListView originally, it was less problematic with styling but moving this to Silverlight app, I found out that it doesn't have ListView so I just used ListBox.
I want my app to be easily ported in Silverlight and also in Windows Phone so I used ListBox and now am having a trouble with the style.
My Metro app has Dark theme and I have custom ListBoxItem but am not sure why when I clicked on it, it looks like this
originally when using ListView, it looks like this
adding background color in my custom ItemsTemplate make it look this
How do I get rid of that White background and also restyle the item when hovered because it looks like this
this my XAML for listbox so far
<ListBox Grid.Row="3" Name="lvSubmeters" VerticalAlignment="Top" HorizontalAlignment="Stretch" SelectedItem="{Binding Path=SelectedListViewItem, Mode=TwoWay}" SelectedIndex="{Binding Path=SelectedListViewIndex, Mode=TwoWay}" ItemTemplate="{StaticResource SubmeterItems}" ItemsSource="{Binding Path=Store.AllItems}" Background="{x:Null}" Foreground="White">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="Foreground" Value="White" />
<Setter Property="Margin" Value="0" />
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
and also if you want my custom ItemsTemplate
<DataTemplate x:Name="SubmeterItems">
<Grid VerticalAlignment="Top" HorizontalAlignment="Stretch" Margin="5,5,5,5">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="166"/>
<ColumnDefinition Width="100*"/>
<ColumnDefinition Width="200"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0" VerticalAlignment="Top">
<TextBlock HorizontalAlignment="Stretch" VerticalAlignment="Top" Text="{Binding MeterID}" FontSize="24" FontWeight="Bold" Foreground="#FF429AA3" />
<TextBlock HorizontalAlignment="Stretch" VerticalAlignment="Top" Text="{Binding Fullname}" FontSize="16" />
</StackPanel>
<StackPanel Grid.Column="1" VerticalAlignment="Top" Height="95">
<TextBlock HorizontalAlignment="Stretch" VerticalAlignment="Top" Text=" " FontSize="24" FontWeight="Bold" Foreground="#FF429AA3" />
<Grid>

<ColumnDefinition Width="100"/>
<ColumnDefinition Width="29*"/>

<StackPanel Grid.Column="0">
<TextBlock Grid.Column="0" VerticalAlignment="Top" Text="Last Reading:" FontSize="14" Margin="0,0,5,5" />

I tried taking this to Blend 4 but I can't find the way to do it.
It looks to me like your screenshots from above don't quite match the XAML that you've provided, however I think I can answer your questions.
For the white border around each item - From the way that the border changes to Purple when the item is selected, you can tell that it is part of the ItemContainer (because that is what gets selected). The ItemContainer will contain the Content of each ListBoxItem. The Content is rendered using the DataTemple (or ItemTemplate property). In your DataTemplate, you have a margin of 5 around the topmost grid, meaning that when the Content is rendered using that DataTemplate, there will be a margin around the outside of the content. That seems to be what you're getting with your white border around each item, so I'm pretty sure that's what is going on. Get rid of the margin in the top most grid of the DataTemplate, and the white border will be gone. If this isn't correct, please provide more complete XAML example (including the parent XAML element of the Listbox) because the xaml above, on its own, does not yield a white border when the Window background is Black.
Changing the colors/style of the ListBoxItem is pretty easy, and there are several ways to do it. The easiest way (in my opinion) is to add a trigger to the ItemContainerStyle that adjusts the background color on MouseOver. Here is a simple example, extending your existing ItemContainerStyle (triggers can be much more advanced, if you wish):
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="Foreground" Value="White" />
<Setter Property="Margin" Value="5" />
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Green"/>
</Trigger>
</Style.Triggers>
</Style>
</ListBox.ItemContainerStyle>
Hope that helps.
