So I am curious to why the scrollviewers repeatbutton at the bottom is white, it should be transparent, I didnt notice this until I resized my scrollviewer to fit perfectly, how do I change it's color to transparent?
I was looking throught the
RepeatButton part of the style and tried changing the background property but that didn't work either, it did nothing.
I even tried hiding it like so
<RepeatButton x:Name="PageDown"
Command="ScrollBar.PageUpCommand"
Opacity="0"
Focusable="false"
Visibility="Hidden"/>
But that didnt work either, it was still there.

And the actual scrollviewer
<ScrollViewer Height="380"
Margin="10">
<ListView ItemsSource="{Binding MessageViewModel.Messages}"
x:Name="MyListView"
Background="Transparent"
BorderThickness="0"
Height="380">
<ListView.ItemTemplate>
<DataTemplate>
<WrapPanel>
<TextBlock Text="{Binding Message}"
FontFamily="Consolas"
Foreground="#61d73d"
TextWrapping="Wrap"/>
</WrapPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
like Klaus, I think the issue is not with your repeatButton. Rather, you see the (white) background through your repeatButton.
try putting a red rectangle just behind your scrollButton to see the outcome
or even better : use snoop to check this kind of issue.
but also, Clemens is right : style/template the scrollviewer inside the listView, rather than outside.

I working for a project and i have some trouble with Listview's scrollbar
Problem: this scrollbar thumb is shortly according to content height.

What can I do that?
I have applied the evernote tag control which is working but the design is not in multi line as I add tag it is added next to the previous tag and adding in the single line, but it has to move down when there is no more space on the page. Here is the screenshot of what I want:

I am getting these tags as:
Currently, you use a StackPanel as ItemsPanel, but a stack panel will never wrap its items in multiple dimensions. So instead, you should try panels like WrapPanel or UniformGrid
For the WrapPanel, you also need to set a Width in the ItemContainerStyle in order to assure same size for all tag items (according to your "what I want" picture).
Then you have to decide on the positioning of your PART_CreateTagButton button. With multi lines of tags, the grid layout of ItemsPresenter and PART_CreateTagButton might no longer be appropriate.
You can probably create a compound items source of the original tag items source and the button as last item. This way, the button will always be properly aligned with the tags. See Add extra items when using ItemsSource and How do you bind a CollectionContainer to a collection in a view model? for more details.
Here's an example where it is not working:
<Window x:Class="WpfApplication2.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication2"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<TreeView HorizontalAlignment="Stretch">
<TreeViewItem Header="Stuff" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch">
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Label Grid.Column="0">Some random text</Label>
<TextBox Grid.Column="1"></TextBox>
</Grid>
</TreeViewItem>
</TreeView>
</Window>
I want the text box to stretch to the width of the window, but instead you get this:
The textbox expands as you type, which is not what I want.
I am thinking now it might be possible to set a binding on the width of the 2nd column to the width of the TreeViewItem but I'm not sure how to do that.
I've tried putting the grid in assorted panels, but that doesn't work either. I have also set the HorizontalAlignment and HorizontalContentAlignment to Stretch on the textbox itself, but that also doesn't work.
Is this some limitation of the Grid control? Putting a textbox in a tree view by itself will make it expand as I want, but I need the label to be next to it and if there are multiple fields it looks MUCH better if all the textboxes are aligned.
UPDATE
Using a different ControlTemplate allows headers to stretch but contents still don't stretch.
<TreeView HorizontalAlignment="Stretch">
<TreeViewItem Style="{DynamicResource StretchableTreeViewItemTemplate}" HorizontalAlignment="Stretch" Header="Stuff">
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>

<TextBox Grid.Column="1" HorizontalAlignment="Stretch"></TextBox>

Trying with Pikoh's solution:
<local:StretchingTreeView HorizontalAlignment="Stretch">
<local:StretchingTreeViewItem HorizontalAlignment="Stretch" Header="Stuff">
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Label Grid.Column="0">Some random text</Label>
<TextBox Grid.Column="1" HorizontalAlignment="Stretch"></TextBox>
</Grid>
</local:StretchingTreeViewItem>
</local:StretchingTreeView>
Try something like this:
<TextBox Grid.Column="1" Width="{Binding Path=ActualWidth, RelativeSource={RelativeSource AncestorType={x:Type Grid}}, Mode=OneWay}"></TextBox>
Edit
Ok,i've found one solution Here. It basically creates a new class inheriting Treeview:
class StretchingTreeView : TreeView
{
protected override DependencyObject GetContainerForItemOverride()
{
return new StretchingTreeViewItem();
}
protected override bool IsItemItsOwnContainerOverride(object item)
{
return item is StretchingTreeViewItem;
}
}
class StretchingTreeViewItem : TreeViewItem
{
public StretchingTreeViewItem()
{
this.Loaded += new RoutedEventHandler(StretchingTreeViewItem_Loaded);
}
private void StretchingTreeViewItem_Loaded(object sender, RoutedEventArgs e)
{
// The purpose of this code is to stretch the Header Content all the way accross the TreeView.
if (this.VisualChildrenCount > 0)
{
Grid grid = this.GetVisualChild(0) as Grid;
if (grid != null && grid.ColumnDefinitions.Count == 3)
{
// Remove the middle column which is set to Auto and let it get replaced with the
// last column that is set to Star.
grid.ColumnDefinitions.RemoveAt(1);
}
}
}
protected override DependencyObject GetContainerForItemOverride()
{
return new StretchingTreeViewItem();
}
protected override bool IsItemItsOwnContainerOverride(object item)
{
return item is StretchingTreeViewItem;
}
}
Example usage:
<Window x:Class="WpfApplication2.Window2"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication2"
Title="Window2" Height="300" Width="300">
<Grid>
<local:StretchingTreeView HorizontalAlignment="Stretch" >
<local:StretchingTreeViewItem Header="Stuff" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" >
<Grid HorizontalAlignment="Stretch" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Label Grid.Column="0">Some random text</Label>
<TextBox Grid.Column="1" ></TextBox>
</Grid>
</local:StretchingTreeViewItem>
</local:StretchingTreeView>
</Grid>
The core of the issue (and the way to fix it) is described here:
The default ControlTemplate for the TreeViewItem uses a grid of 3 columns x 2 rows, defined such that the content cannot stretch horizontally. The author also gives a modified style, that changes the grid so that the content can stretch.
Note that the modified style sets the HorizontalContentAlignment of TreeViewItem to Center, and that the ControlTemplate uses this property for aligning the content.
To achieve the desired effect, either set HorizontalContentAlignment to Stretch in the modified style, or override just that property on the TreeView (or specific TreeViewItems).
Missing the BasedOn="{StaticResource {x:Type TreeViewItem}}" part causes the TreeViewItem to revert to using the default ControlTemplate, with the non-stretchable grid.
<Style TargetType="TreeViewItem" BasedOn="{StaticResource {x:Type TreeViewItem}}">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
In a HierarchicalDataTemplate, the effect would be achieved by using the ItemContainerStyle property.
#pikoh's method of deriving from TreeView and TreeViewItem achieves the same, by modifying the grid from code.

Due to an odd design decision by Microsoft when creating WPF, tree items can't stretch without replacing the control template.
See http://leecampbell.blogspot.com/2009/01/horizontal-stretch-on-treeviewitems.html
The required style is:
<Style TargetType="TreeViewItem"
BasedOn="{StaticResource {x:Type TreeViewItem}}">
<Setter Property="HorizontalContentAlignment"
Value="Center" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TreeViewItem">
<StackPanel>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"
MinWidth="19" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition />
</Grid.RowDefinitions>

It seems like Grid's HorizontalAlignment Issue. I've tried it in .Net Framework 4 and it all works fine. Seems like in 4.5 even though you specify HorizontalAlignment as Stretch, it actually doesn't stretch it. So you can do a binding like below:
<Grid HorizontalAlignment="Stretch"
Width="{Binding RelativeSource={RelativeSource AncestorType={x:Type TreeViewItem}},Path=ActualWidth,Mode=OneTime}"
>
Cause you can see in the run time that TreeViewItem has Width expected but Grid doesn't.
All you need to do is add Grid.ColumnSpan='2' to the ControlTemplate of the TreeViewItem as shown below.
Thats it!
Explanation:
The default ControlTemplate places the Header Content in a Grid column that does not stretch. The Grid.ColumnSpan='2' instructs the Header content to span to the rest of the Grid.
I want to add some text next to my button, but I want to use the tooltip for this text or better yet another tag I can add within the controls properties.
Then I want to reference this tag within my ControlTemplate so it will add the text next to my button, here is my button XAML:
<Button Style="{StaticResource MainMenuButton}" ToolTip="Home" Content="" />
And here is my Style:
<Style x:Key="MainMenuButton" TargetType="Button">
<Setter Property="FontFamily" Value="{StaticResource FontAwesome}" />
<Setter Property="FontSize" Value="27" />
<Setter Property="Foreground" Value="White" />
<Setter Property="Background" Value="#545863" />
<Setter Property="Padding" Value="15" />
<Setter Property="Margin" Value="5" />
<Setter Property="HorizontalAlignment" Value="Center" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid x:Name="grid">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Border Grid.Column="0" x:Name="border"
CornerRadius="40"
BorderThickness="0"
Background="{TemplateBinding Background}"
Padding="{TemplateBinding Padding}"
Margin="{TemplateBinding Margin}">
<ContentPresenter HorizontalAlignment="Center"
VerticalAlignment="Center"
TextElement.FontWeight="Bold" />
</Border>
<StackPanel Grid.Column="1" VerticalAlignment="Center">
<TextBlock Text="{Binding RelativeSource={RelativeSource Self}, Path=DataContex.ToolTip}"
FontSize="16"/>
</StackPanel>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#757b8d" />
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Background" Value="#29a1d5" />
</Trigger>
</Style.Triggers>
</Style>
The code I have there now doesn't work: {Binding RelativeSource={RelativeSource Self}, Path=DataContex.ToolTip}.
Woopps, found the solution. Was far too simple and I expected it be more complicated.
<TextBlock Text="{TemplateBinding Tag}" FontSize="16"/>
Im new to WPF Application. I need to customize my combobox like this image.

This is a blog with example code on how to make a custom Combobox. The custom combobox he is making looks very much like the one you need. So I think this will be very useful to you.
Here is a complete style for WPF ComboBox. It is also easy to customize.
