I have a style for an image button as the following, how could I make the Text of the TextBlock, where equals "POSITION' below, the same as the Content of the button? Thanks.`
<Style x:Key="TopButtonStyle" TargetType="Button">
<Setter Property="Padding" Value="0"/>
<Setter Property="Button.BorderBrush" Value="SteelBlue" />
<Setter Property="Button.BorderThickness" Value="0" />
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<Grid Background="SteelBlue">
<Image Source="images/blue_button_up.png" HorizontalAlignment="Center" Margin="0,0,0,0" Height="Auto" Width="Auto" Stretch="UniformToFill"/>
<TextBlock Text="POSITION" HorizontalAlignment="Center" Foreground="White" Margin="5,5,0,0"/>
</Grid>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>`
{Binding} because the DataContext in the ContentTemplate is the Content.

I want to show Image inside of the Title of header in TabControl
This question(WPF TabItem - Image Binding) seems is right, but I have using Triggers and it doesn't help on my code.
Here is what I have Providing:
<TabControl Name="MainTabControl" Margin="0,28,0,0" TabStripPlacement="Top" >
<TabControl.Resources>
<Image x:Key="imgProfile" Source="/Icons/red icons/profile.png" />
<Image x:Key="imgComment" Source="Icons/red icons/notification.png" />
<Style TargetType="TabItem" >
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate>
<WrapPanel>
<TextBlock Text="{Binding}"
MouseDown="UIElement_OnMouseDown"
FontSize="18"
/>
<Image Height="25" Margin="4,0,4,0"
Source="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Tag.Source}" />
</WrapPanel>
</DataTemplate>
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabItem">
<Border Name="Border" BorderThickness="1,1,1,0" BorderBrush="Gainsboro" CornerRadius="0" Margin="2,0">
<ContentPresenter x:Name="ContentSite"
VerticalAlignment="Center"
HorizontalAlignment="Center"
ContentSource="Header"
Margin="5,2"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="False">
<Setter TargetName="Border" Property="BorderBrush" Value="Transparent" />
<Setter TargetName="Border" Property="Background" Value="Transparent" />
<Setter Property="Foreground" Value="{DynamicResource TabItemNormal}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</TabControl.Resources>
<TabItem Name="tiProfile" Header="a" Tag="{StaticResource imgProfile}"></TabItem>
<TabItem Name="tiComment" Header="b" Tag="{StaticResource imgComment}"></TabItem>
</TabControl>
the binding from TabItem.HeaderTemplate to the TabItem.Tag must be via FindAncestor of TabItem type.
instead create Images in Resources, create BitmapImage, and bind it the Image.Source.
so, Resources:
<BitmapImage x:Key="imgProfile" Source="/Icons/red icons/profile.png" />
<BitmapImage x:Key="imgComment" Source="Icons/red icons/notification.png" />
Header DataTemplate:
<Image Height="25" Margin="4,0,4,0"
Source="{Binding Tag, Mode=OneWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type TabItem}}}" />
I am trying to set up a sort of menu using ListBox and buttons as ListBoxItems to trigger a command when selection changes, but the result is that some times the selected ListBoxItem is changed but the command is not triggered, other times the opposite. The XAML is the following:

<DataTemplate DataType="{x:Type viewModels:TripViewModel}">
<views:TripView />
</DataTemplate>
<DataTemplate DataType="{x:Type viewModels:AddTripViewModel}">

Am I doing right trying to insert a button in the ItemContainerTemplate? Would it be better to use the code behind to trigger the selection changed?
I am trying to create a sort of left menu for navigation inside the desktopapplication. My idea is to use Buttons as Listview items which should behave in this way: when i hover with the mouseover them theri background should change color (becomes darkCyan) and when i click one its background color should change persistently (to darkCyan) until i click on another button of the list. The problem is that i am using a the DataTemplate property to specify how the buttons should look like and I am tryin to apply the triggers to change the background color on the ControlTemplate of the ListView. The result is that sometimes the background color changes but the command related to the button is not fired other times the contrary. I think that I am doing the things in the wrong element of the tree view, but I don't have enough knowledge of the tree view so I am not understanding what I am doing wrong. Here is the code of the XAML in which i define the styles for the Buttons and the ListView
<Window.Resources>
<DataTemplate DataType="{x:Type viewModels:TripViewModel}">
<views:TripView />
</DataTemplate>
<Style TargetType="{x:Type Button}">
<Setter Property="Height"
Value="50" />
<Setter Property="Background"
Value="#555D6F" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border>
<Grid Background="Transparent">
<ContentPresenter HorizontalAlignment="Center"
VerticalAlignment="Center" />
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style TargetType="{x:Type ListViewItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListViewItem}">
<Border BorderBrush="Transparent"
BorderThickness="0"
Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center"
VerticalAlignment="Center" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver"
Value="True">
<Setter Property="Background"
Value="DarkCyan" />
</Trigger>
<Trigger Property="IsSelected"
Value="True">
<Setter Property="Background"
Value="DarkCyan" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
And here is the code in which I create the ListView
<ListView Name="MenuButtons"
ItemsSource="{Binding PageViewModels}"
Background="Transparent"
IsSynchronizedWithCurrentItem="True">
<ListView.ItemTemplate>
<DataTemplate>
<Button Content="{Binding Name}"
Command="{Binding DataContext.ChangePageCommand, RelativeSource={RelativeSource AncestorType={x:Type Window}}}"
Margin="0" />
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Anyone can help?
Thanks
I have solved the issue by using a ListBox instead of a ListView and setting the ItemContainer to be a button in the following way
<ListBox.ItemTemplate>
<ItemContainerTemplate>
<Button Content="{Binding Name}"
Command="{Binding DataContext.ChangePageCommand, RelativeSource={RelativeSource AncestorType={x:Type Window}}}"
Margin="0" />
</ItemContainerTemplate>
</ListBox.ItemTemplate>
I want to set a style for my DataGrid, but I do not know where is the problem
the backgroud property does not work with its value in the presence of the Template property.
my code:
<Style x:Key="DataGridStyle1" TargetType="{x:Type DataGrid}">
<Setter Property="CellStyle" Value="{DynamicResource GridStyle1}"/>
</Style>
<Style x:Key="GridStyle1" TargetType="DataGridCell">
<Style.Triggers>
<Trigger Property="IsSelected" Value="True" >
<Setter Property="Background" Value="SeaGreen"/>
</Trigger>
</Style.Triggers>
<Style.Setters>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridCell}">
<Border Name="DataGridCellBorder">
<ContentControl Content="{TemplateBinding Content}">
<ContentControl.ContentTemplate>
<DataTemplate>
<TextBlock Background="Transparent" TextWrapping="WrapWithOverflow" TextTrimming="CharacterEllipsis"
Height="auto" Width="auto" Text="{Binding Text}"/>
</DataTemplate>
</ContentControl.ContentTemplate>
</ContentControl>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style.Setters>
</Style>
Help me please.
You have explicitly set TextBlock background to Transparent, so it won't pick value from DataGridCell. You should bind with background of DataGridCell using RelativeSource like this:
<TextBlock Background="{Binding Background, RelativeSource={RelativeSource
Mode=FindAncestor, AncestorType=DataGridCell}}"
TextWrapping="WrapWithOverflow" TextTrimming="CharacterEllipsis"
Height="auto" Width="auto" Text="{Binding Text}"/>
I have bumped into a problem to which I am seeking the solution.
I have a tabControl with styles added to it.
I want to display only images on each TabItem.Header and when that tab is selected then hide the image from header and display text (the other, inactive headers will be showing images).
Can anybody provide any help?
<Window.Resources>
<Style TargetType="{x:Type TabItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid Name="Borderer" Background="#FF777777" Height="70" Width="90">
<ContentPresenter x:Name="ContentTabItem" ContentSource="Header" VerticalAlignment="Center" HorizontalAlignment="Center" />
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Foreground" Value="#FF000000" />
<Setter TargetName="Borderer" Property="Background" Value="WhiteSmoke" />
<Setter Property="Header" >
<Setter.Value>
<Grid>
<ContentPresenter ContentSource="Tag" />
</Grid>
</Setter.Value>
</Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Grid>
<TabControl Height="189" HorizontalAlignment="Left" Margin="94,123,0,0" Name="tabControl1" VerticalAlignment="Top" Width="500">
<TabItem Name="tabItem1" IsSelected="True" >
<TabItem.Tag>
<TextBlock Text="blab lab la" />
</TabItem.Tag>
<TabItem.Header>
<Image Source="images/img1.png" Width="35" Height="35" />
</TabItem.Header>
<TabItem.Content>
<Grid>
<TextBlock Name="aaa" />
</Grid>
</TabItem.Content>
</TabItem>
<TabItem >
<TabItem.Tag>
<TextBlock Text="la lab blab" />
</TabItem.Tag>
<TabItem.Header>
<Image Source="images/img2.png" Width="35" Height="35" />
</TabItem.Header>
<TabItem.Content>
<Grid>
<TextBlock Name="bbb" />
</Grid>
</TabItem.Content>
</TabItem>
</TabControl>
</Grid>
You can actually do this without replacing the whole ControlTemplate on the TabItem. You can just alter the TabItem's HeaderTemplate when the TabItem is selected, making your Style a lot shorter:
<DataTemplate x:Key="SelectedHeaderTemplate" >
<ContentControl Content="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=TabItem},
Path=Tag}" />
</DataTemplate>
<Style TargetType="{x:Type TabItem}">
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="HeaderTemplate" Value="{StaticResource SelectedHeaderTemplate}" />
</Trigger>
</Style.Triggers>
</Style>
