WPF Custom Buttons below ListBox Items - wpf

WPF Experts -
I am trying to add buttons below my custom listbox and also have the scroll bar go to the bottom of the control. Only the items should move and not the buttons. I was hoping for some guidance on the best way to achieve this. I was thinking the ItemsPanelTemplate needed to be modified but was not certain.
Thanks
My code is below
<!-- List Item Selected -->
<LinearGradientBrush x:Key="GotFocusStyle" EndPoint="0.5,1" StartPoint="0.5,0">
<LinearGradientBrush.GradientStops>
<GradientStop Color="Black" Offset="0.501"/>
<GradientStop Color="#FF091F34"/>
<GradientStop Color="#FF002F5C" Offset="0.5"/>
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
<!-- List Item Hover -->
<LinearGradientBrush x:Key="MouseOverFocusStyle" StartPoint="0,0" EndPoint="0,1">
<LinearGradientBrush.GradientStops>
<GradientStop Color="#FF013B73" Offset="0.501"/>

<GradientStop Color="#FF014A8F" Offset="0.5"/>

Why don't you place the two controls (the list and the buttons panel) into a StackPanel?
<StackPanel HorizontalAlignment="Left" Margin="0,0,0,0" Width="240">
<ListBox Height="320"/>
<Button Content="buttons go here"/>
</StackPanel>
You obviously won't get the listbox's scrollbar to go to the bottom of the screen, but you could fix that by putting in a ScrollBar control.
Editing templates might yield what you want but you may simply run into a point where items at the bottom of the list could be hidden by the button panel. You could overcome this obviously by increasing the bottom padding of the last item in that list or a similar margin/padding hack.
However, I don't think sizing the scrollbar to the bottom is the best idea in terms of common sense in user interfaces as scrollbars should conventionally be placed on the side of only what is scrollable.

I know I'm joing the party rather late, but you should be able to accomplish this by applying a custom ScrollViewier control template to be used by the ListBox. I have not tested this, but it should work (or at least offer a starting point):
<ListBox ...>
<ListBox.Resources>
<Style TargetType="ScrollViewer">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ScrollViewer">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<!-- Items Go Here -->
<ScrollContentPresenter Grid.Column="0" />
<!-- Buttons Go Here -->
<Grid Grid.Column="0"
Grid.Row="1"
>
...
</Grid>
<!-- ScrollBar spans all three rows but should only affect the presenter -->
<ScrollBar x:Name="PART_VerticalScrollBar"
Grid.Column="1"
Grid.Row="0"
Grid.RowSpan="3"
Value="{TemplateBinding VerticalOffset}"
Maximum="{TemplateBinding ScrollableHeight}"
ViewportSize="{TemplateBinding ViewportHeight}"
Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}"
/>
<ScrollBar x:Name="PART_HorizontalScrollBar"
Grid.Column="0"
Grid.Row="1"
Orientation="Horizontal"
Value="{TemplateBinding HorizontalOffset}"
Maximum="{TemplateBinding ScrollableWidth}"
ViewportSize="{TemplateBinding ViewportWidth}"
Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}"
/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.Resources>
</ListBox>

Gong drag and drop: drag effect border does not fit element

Using the gong drag and drop framework, one gets a drag effect, which is a simple border around the possible droptarget.
However, in my case for some reason this border doesn't fit the actual element, as shown here:
I have already tried to change background colors of the different xaml elements of the drop target to find out if some elements are bigger (but hidden), but couldn't find any.
I guess the problem is due to the usage of viewboxes, which I use, since the size of these drop targets is dynamic and zoom-able.
Here is the xaml code of drop target:
<Border BorderThickness="{Binding PlatformBorderThickness}" dd:DragDrop.IsDropTarget="True" dd:DragDrop.DropHandler="{StaticResource CustomDropHandler}" >
<Border.BorderBrush>
<LinearGradientBrush StartPoint="0,0" EndPoint="1,0" >
<GradientStop Color="Black" Offset="0"/>
<GradientStop Color="Black" Offset="0.1"/>
<GradientStop Color="Transparent" Offset="0.1"/>
<GradientStop Color="Transparent" Offset="0.9"/>
<GradientStop Color="Black" Offset="0.9"/>
<GradientStop Color="Black" Offset="1"/>
</LinearGradientBrush>
</Border.BorderBrush>

<ColumnDefinition Width="10*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>

<RowDefinition Height="10*"/>
</Grid.RowDefinitions>
<Viewbox Grid.Column="0" Grid.ColumnSpan="1" Grid.Row="0" Grid.RowSpan="1" HorizontalAlignment="Left">
<TextBlock Text="{Binding Equipment.Name, FallbackValue='Please add a device!'}" FontWeight="Bold"/>
</Viewbox>
<Viewbox Grid.Column="1" Grid.ColumnSpan="1" Grid.Row="0" Grid.RowSpan="1" Stretch="Uniform" HorizontalAlignment="Right">
<Button Command="{Binding DeleteButtonClick}" Background="Transparent" BorderThickness="0"
Margin="0" Padding="0">
<Image Source="/Resources/Cancel.ico"/>
</Button>
</Viewbox>
<Viewbox Grid.Column="0" Grid.ColumnSpan="3" Grid.Row="1" Grid.RowSpan="1" HorizontalAlignment="Left" VerticalAlignment="Top" Stretch="Uniform" Margin="2">
<DataGrid Width="200" Height="135" HeadersVisibility="None" RowBackground="Transparent" BorderThickness="0"
ItemsSource="{Binding Equipment.Settings}" SelectionMode="Single" AutoGenerateColumns="False" GridLinesVisibility="Vertical" CanUserAddRows="False"

</DataGrid.Resources>

</DataGrid.Background>

<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button Name="DutInfoGridRemoveButton" Background="Transparent" BorderThickness="0" Margin="0" Padding="0" Height="15"
Command="{Binding Path=DataContext.RemoveClick, RelativeSource= {RelativeSource FindAncestor, AncestorType={x:Type DataGrid}}}"
CommandParameter="{Binding}">
<Image Source="/Resources/Trash.ico"/>
</Button>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
<DataGridTextColumn Binding="{Binding Items[3].Value}"/>
<DataGridTextColumn Binding="{Binding Items[6].Value}" />
</DataGrid.Columns>
</DataGrid>
</Viewbox>
</Grid>
</Border>
Edit:
After some further testing I found out that if I remove the ViewBox element around the datagrid, the problem is gone. Any ideas, why the ViewBox causes this issue and how to solve it?
You should probably switch to the action file, then swap and use jQuery with the XML code which will refer to the drag and drop.

WPF - Showing specific data for Grid on case of using window style

I have providing a windows style for all of my windows:
Here is what I adding on app.xaml
<Style x:Key="Style.Window.Default" TargetType="Window">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Window">
<Grid Background="{TemplateBinding Background}">
<Grid Name="gridBar" Height="40" VerticalAlignment="Top" Margin="1,0,1,0">
<Grid.Background>
<LinearGradientBrush StartPoint="0, 0" EndPoint="0, 1" Opacity=".1">
<GradientStop Offset="0" Color="{DynamicResource AccentColor}" />
<GradientStop Offset=".3" Color="{DynamicResource AccentColor}" />
<GradientStop Offset="1" Color="Transparent" />
</LinearGradientBrush>
</Grid.Background>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<!-- title -->
<ItemsControl Background="Transparent" MouseDoubleClick="MaximizeClick" >
<TextBlock Text="{TemplateBinding Title}" Margin="8,8,8,0" x:Name="txtTitle"
Style="{StaticResource ModernWindowTitle}"
/>
</ItemsControl>
</Grid>
<Grid VerticalAlignment="top" Margin="0,40,0,0" Background="White">
</Grid>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
And here is what I have on each window:
<Window x:Class="WpfApplication1.MainWindow1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Height="300" Width="300" Title="title"
Style="{StaticResource Style.Window.Default}" >
<Grid>
<TextBlock Text="text of window 1"></TextBlock>
</Grid>
</Window>
How could I change my code for having or showing data of Grid, because it's not showing data of the Grid
Use a content presenter to insert the content in the ControlTemplate. You never say where you want the content to appear, but this top-aligned grid is empty so maybe that's where?
<Grid VerticalAlignment="top" Margin="0,40,0,0" Background="White">
<ContentPresenter
/>
</Grid>
I have a question for you: What is the purpose of the ItemsControl here?
<!-- title -->
<ItemsControl Background="Transparent" MouseDoubleClick="MaximizeClick" >
<TextBlock Text="{TemplateBinding Title}" Margin="8,8,8,0" x:Name="txtTitle"
Style="{StaticResource ModernWindowTitle}"
/>
</ItemsControl>
Another question: Why do you define four columns in your grid and never use any of them? What are those columns for?

How to remove border from Textbox in WPF?

These borders appear when they are clicked or hovered and don't go until the focus is lost.
There are borders on all four sides but since it is embedded in a shorter grid, the top and bottom ones are not visible.
How to remove these borders?
Please provide an example if possible.
XAML:
<Border x:Name="SearchBorder" BorderThickness="1" HorizontalAlignment="Left" Height="40" Margin="672,34,0,0" VerticalAlignment="Top" Width="355" Background="#3F000000">
<Border.BorderBrush>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="#4C000000" Offset="0"/>
<GradientStop Color="#3FFFFFFF" Offset="1"/>
</LinearGradientBrush>
</Border.BorderBrush>
<Grid>
<TextBox x:Name="SearchBox" HorizontalAlignment="Left" Height="40" Width="296" Margin="10,0,0,0" TextWrapping="Wrap" VerticalAlignment="Center" SelectionBrush="Black" Background="#00000000" Foreground="#FF5B5B5B" FontSize="25" FontFamily="Segoe UI Light" BorderBrush="#00000000" CaretBrush="#FF6C6C6C"/>
<TextBlock HorizontalAlignment="Left" Height="23" Margin="320,0,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Center" Width="21" FontFamily="FontAwesome" FontSize="25" Foreground="#FF919191"/>
<Rectangle HorizontalAlignment="Left" Margin="311,-2,0,0" Width="1">
<Rectangle.Stroke>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="#3F404040" Offset="0"/>
<GradientStop Color="#3F686868" Offset="1"/>
<GradientStop Color="#59DADADA" Offset="0.502"/>
</LinearGradientBrush>
</Rectangle.Stroke>
</Rectangle>
</Grid>
</Border>
Try BorderThickness="0"
<TextBox x:Name="SearchBox" BorderThickness="0" HorizontalAlignment="Left" Height="40" Width="296" Margin="10,0,0,0" TextWrapping="Wrap" VerticalAlignment="Center" SelectionBrush="Black" Background="#00000000" Foreground="#FF5B5B5B" FontSize="25" FontFamily="Segoe UI Light" BorderBrush="#00000000" CaretBrush="#FF6C6C6C"/>
you can remove the border by just setting the BorderBrush property to Transparent.
Normal View: Set the BorderBrush property to "Transparent"
<Button Name="BtnTest"
Content="Test"
BorderBrush="Transparent"
Height="20"
Width="75"/>
Hovering View: While you are hovering the control with mouse, Include these Control Template for Button or any control like Textbox or Textblock etc.. under the Window.Resources Tag
<Window.Resources>
<Style TargetType="Button">
<!--Default Values-->
<Setter Property="BorderBrush"
Value="Transparent"/>
<!--Transparent Highlight-->
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center"
VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>

Datatemplate for Tabitem doesn't cover all the tabitem space (WPF Tabcontrol)

i have a datatemplate for a tabitem in a tab control.
The datatemplate doesn't cover all the Tabitem control, the beckground is a gray or white, control default color.
The Datatemplate of the TabItem:
<DataTemplate x:Key="ClosableTabItemTemplate">
<Border BorderThickness="1" BorderBrush="Transparent" CornerRadius="4">
<!--Border to make the tab item gap from the content-->
<Border x:Name="InsideBorder" BorderThickness="3" BorderBrush="#D6EAFF" CornerRadius="4">
<!--Border for the rounded corners-->
<!--TabItem Content Grid-->

The Tabcontrol:
<TabControl Name="MainTabCtrl" Margin="0" Padding="0" BorderThickness="0" Background="Transparent"
IsSynchronizedWithCurrentItem="True"
ItemsSource="{Binding Path=TabViewModels}"
ItemTemplate="{StaticResource ClosableTabItemTemplate}">
when the Xaml code of the tabitem wasn't inside a DataTemplate it worked fine - the "Transparent" of the first border did the job and no gray/white background appeared. but when i moved the code inside a DataTemplate the gray background appeared.
How do i make the background of the tabitem transparent?
I added HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" to the tabcontrol, it only narrows the gray area a bit but it still exsits.
Try to set Padding for TabItems to zero.

how to change the color of the circle inside radio button

I want to change only the color inside the radio button when clicked. I mean the tiny dot inside the circle.
How in WPF can i do this?
I tried this code but it is saying the content is set more than once
<BulletDecorator Background="Transparent">

Thanks in advance,

Move your ContentPresenter outside of your StackPanel. Actually, you don't appear to need the StackPanel at all:
<BulletDecorator Background="Transparent">
<BulletDecorator.Bullet>
<Grid Width="40" Height="40">
<Ellipse Name="MainEllipse" Width="40" Height="40">
<Ellipse.Fill>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="#FFC8C8C8" Offset="0" />
<GradientStop Color="#FFF7F7F7" Offset="0.991" />
</LinearGradientBrush>
</Ellipse.Fill>
</Ellipse>
<Ellipse Margin="10,10,10,10"
Fill="#C0C0C0"
Width="Auto"
Height="Auto" />
<Ellipse x:Name="Selected"
Margin="10,10,10,10"
Width="Auto"
Height="Auto">
<Ellipse.Fill>
<SolidColorBrush Color="Navy" />
</Ellipse.Fill>
</Ellipse>
</Grid>
</BulletDecorator.Bullet>
<ContentPresenter Margin="5,0,0,0" VerticalAlignment="Center" />
</BulletDecorator>
