How do I create a custom ListBoxItem with C# and WPF?

I am learning C# and WPF. Now I want to make a customized ListBoxItem. With my own style. Containing some TextBlocks and a Image.
How do I achieve that?
I've tried to derive a Class from ListBoxItem but that dosn't work.
I also created a Style with ControleTemplate but I can't figure out how I can change the Text property of the TextBlocks inside the Template.
<Style TargetType="ListViewItem">
<Setter Property="Background" Value="White"/>
<Setter Property="Height" Value="75"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate x:Name="test" TargetType="{x:Type ListViewItem}">
<Grid Background="{TemplateBinding Background}" Width="{TemplateBinding Width}" Height="{TemplateBinding Height}" Margin="0,2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="25"/>
<RowDefinition Height="25"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<StackPanel Grid.Column="0" Grid.RowSpan="3" VerticalAlignment="Center" HorizontalAlignment="Center" Width="80" Height="{TemplateBinding Height}">
<StackPanel.Background>
<ImageBrush ImageSource="media/pictures/noImage.png"/>
</StackPanel.Background>
</StackPanel>
<TextBlock x:Name="lbl_Heading" Text="HowToAccessThisProperty" Grid.Column="1" Grid.Row="0" FontSize="14" FontWeight="Bold" VerticalAlignment="Center"/>
<TextBlock Name="lbl_Description" Text="HowToAccessThisProperty" Grid.Column="1" Grid.Row="1" FontSize="12" VerticalAlignment="Center"/>
<TextBlock Name="lbl_FurtherInfo" Text="HowToAccessThisProperty" Grid.Column="1" Grid.Row="2" FontSize="10" VerticalAlignment="Center"/>
<ContentPresenter/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Thank you :)

wpf controltemplate is applied to window,and how to add controls

i have defined a controltemplate that is used to windows ,then windows have the same view as basically.
after that ,i should add different controls in different windows. and i have no idea how to add the elements' host in controltemplate to hold different parts of controls which likes the picture bellow.
and one more thing, how to access the controls and how to set the buttons' actions in controltemplate of different window? it should be use a windowBase class to do that ?
first .the screen picture
and the control template file

<uctrls:UserControlBase>
<Grid>
<Button Content="what "></Button>
</Grid>
</uctrls:UserControlBase>
</Grid>

i have done it myself.
just use code bellow to host new controls
<AdornerDecorator>
<contentpresenter/>
</AdornerDecorator>
and create a windowBase as parent class of new windows.

WPF: Content of round-cornered border not being round-cornered

I have a round-cornered border and I am trying to make its contents to be also round-cornered but my attempts are not working. Basically I am doing a kind of custom MessageBox but simpler, only with one image icon, a text and a button. No title bar. Image icon is changing depending on the type of message.
Stackpanel corners overlaps over border so border corners are not showing rounded.
ATTEMPT #1:
<Border x:Name="MyCustomMessageBox"
CornerRadius="5,5,5,5"
Grid.ZIndex="3"
Visibility="{Binding IsMessageBoxShown, Mode=TwoWay, Converter={StaticResource BoolToVis}}"
Width="auto" Height="auto"

VerticalAlignment="Center"
BorderBrush="DarkBlue" BorderThickness="1"
Background="White">

</TextBlock>
</StackPanel>
<Button x:Name="btnCustomMessageBox" Grid.Row="1" Grid.Column="0"
Click="btnCustomMessageBox_Click"
HorizontalAlignment="Center" Margin="10" Width="80" Content="Ok" Visibility="Visible"/>
</Grid>
</Border>
ATTEMPT #2:
As explained here, I have tried also but without success.
<Grid>
<Grid.OpacityMask>
<VisualBrush Visual="{Binding ElementName=MyCustomMessageBox}" />
</Grid.OpacityMask>
<!-- Here goes all the above border code -->
</Grid>

The following should solve your issue.
<Border x:Name="MyCustomMessageBox"
CornerRadius="5"
Visibility="{Binding IsMessageBoxShown, Mode=TwoWay, Converter={StaticResource BoolToVis}}"
Width="auto" Height="auto"
HorizontalAlignment="Center"
VerticalAlignment="Center"

BorderThickness="1"
Background="blue">
<Border.Effect>
<DropShadowEffect />
</Border.Effect>

<RowDefinition Height="auto"/>
<RowDefinition Height="50"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<!--
Added a border to fill the top part of the grid with the
whitesmoke color using a borderradius on the top.

<Border

How can I make a border only on one/two sides?

I got to make 4 buttons near each other, I've done it by grid, but I've asked to add borders at only one/two sides (like in the next screenshot)
With borders
So far I've done that:
Without

<Button.Content>
<StackPanel Orientation="Horizontal">
<Image Source="Assets\coffee-icon.png" Stretch="None"/>
<TextBlock Text="Coffe" Margin="10,15,0,0" />
</StackPanel>
</Button.Content>
</Button>
<Button Style="{StaticResource NavagtionButtons}" Grid.Row="0" Grid.Column="2" >
<Button.Content>
<StackPanel Orientation="Horizontal">
<Image Source="Assets\schedule-icon.png" Stretch="None" />
<TextBlock Text="Schedule" Margin="10,15,0,0"/>

So how can I add borders only on the sides he showed?

Button inside Usercontrol not firing properly in WPF

I have a Image buttton kind of usercontrol, which has two textblocks and an image inside button, but button is firing click only when I click on textblock or image part. just to do quick debug I have set button's cursor to Hand, strangely its showing Hand cursor only when mouse is over texblocks/Image but not on any part of the button. Here is my code
Name="Tiles" Background="Green"
d:DesignHeight="300" d:DesignWidth="300" Margin="10,10,10,10">
<UserControl.Resources>
<BooleanToVisibilityConverter x:Key="booleanVisibleConverter" />
<!-- This style is used for buttons, to remove the WPF default 'animated' mouse over effect -->
<Style x:Key="ImgBtnStyle" TargetType="{x:Type Button}">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate x:Name="ImgBtnStyle" TargetType="{x:Type Button}">
<Border Name="border"
BorderThickness="1"
Padding="0"
BorderBrush="DarkGray"
CornerRadius="1"
Background="{TemplateBinding Background}">
<ContentPresenter />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="border" Property="BorderBrush" Value="White" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</UserControl.Resources>
<Button Cursor="Hand" Style="{StaticResource ImgBtnStyle}" Command="{Binding TestClick, ElementName=Tiles}" CommandParameter="{Binding ElementName=Tiles, Path=TestName}" >
<Grid >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*"/>
<ColumnDefinition Width="2*"/>
<ColumnDefinition Width="1*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="1*"/>
<RowDefinition Height="2*"/>
<RowDefinition Height="1*"/>
</Grid.RowDefinitions>
<TextBlock Text="{Binding ElementName=Tiles, Path=ResultValue}" Style="{StaticResource txtblck}" Grid.Column="1" Grid.Row="1"/>
<TextBlock Text="{Binding ElementName=Tiles, Path=TestName}" Style="{StaticResource txtblck}" Grid.Column="0" Grid.Row="2" Grid.ColumnSpan="2" VerticalAlignment="Bottom" TextAlignment="Left" Padding="5,0,0,5"/>
<Image Source="/resources/Icons/tickBlack.png" Grid.Column="2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
Visibility="{Binding Path= TestDone, ElementName=Tiles, Converter={StaticResource booleanVisibleConverter}}"/>
</Grid>
</Button>

Set Grid's Background to Transparent like below :
<Button Cursor="Hand" Style="{StaticResource ImgBtnStyle}" Command="{Binding TestClick, ElementName=Tiles}" CommandParameter="{Binding ElementName=Tiles, Path=TestName}" >
<Grid Background="Transparent">
...
</Button>
I made above changes and it worked fine for me.
