J'utilise ListBox dans mon application. ListBox a deux colonnes. Je veux faire un titre pour les colonnes. C'est mise en page
<Window.Resources>
<Style x:Key="borderBase" TargetType="Border">
<Setter Property="BorderBrush" Value="Black" />
<Setter Property="BorderThickness" Value="1" />
</Style>
</Window.Resources>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
<RowDefinition Height="7*" />
</Grid.RowDefinitions>
<!-- Title -->
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Border Style="{StaticResource borderBase}">
<TextBlock Text="FirstName" />
</Border>
<Border Grid.Column="1" Style="{StaticResource borderBase}">
<TextBlock Text="SecondName" />
</Border>
</Grid>
<!-- Data -->
<ListBox Grid.Row="1">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Border Style="{StaticResource borderBase}">
<TextBlock Style="{StaticResource textBlockBase}" Text="{Binding FirstName}" />
</Border>
<Border Grid.Column="1" Style="{StaticResource borderRigth}">
<TextBlock Style="{StaticResource textBlockBase}" Text="{Binding SecondName}" />
</Border>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
Lorsque quelques éléments du ListBox sont tous affichés, cliquez sur OK. Mais quand beaucoup d'éléments dans la liste - une barre de défilement verticale dans ListBox est visible. Puis le titre et déplacez-vous sur la largeur des colonnes.

Comment aligner la largeur des colonnes et des en-têtes?
WPF fournit certaines propriétés just à cette fin. Vous devez utiliser les propriétés SharedSizeGroup
et Grid.IsSharedSizeScope
:
<Grid Grid.IsSharedSizeScope="True"><!-- Look HERE -->
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
<RowDefinition Height="7*" />
</Grid.RowDefinitions>
<!-- Title -->
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="FirstNameColumn" /><!-- Look HERE -->
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Border Style="{StaticResource borderBase}">
<TextBlock Text="FirstName" />
</Border>
<Border Grid.Column="1" Style="{StaticResource borderBase}">
<TextBlock Text="SecondName" />
</Border>
</Grid>
<!-- Data -->
<ListBox Grid.Row="1">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="FirstNameColumn" />
<ColumnDefinition /><!-- Look Above HERE -->
</Grid.ColumnDefinitions>
<Border Style="{StaticResource borderBase}">
<TextBlock Style="{StaticResource textBlockBase}" Text="{Binding FirstName}" />
</Border>
<Border Grid.Column="1" Style="{StaticResource borderRigth}">
<TextBlock Style="{StaticResource textBlockBase}" Text="{Binding SecondName}" />
</Border>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
Veuillez consulter la page Grid.IsSharedSizeScope Attached Property sur MSDN pour plus d'informations.
Pourquoi si compliqué? Utilisez simplement l'attribut "En-tête" de GridViewColumn ...
<ListView >
<ListView.View>
<GridView>
<GridViewColumn Header="Id"/>
<GridViewColumn Header="Name"/>
</GridView>
</ListView.View>
</ListView>
Je recommanderais d'utiliser un ListView, vous pouvez y définir et styler les en-têtes pour chaque colonne sans avoir à vous soucier du positionnement:
<ListView>
<ListView.View>
<GridView>
<GridViewColumn>
<GridViewColumn.CellTemplate>
<Border Style="{StaticResource borderBase}">
<TextBlock Style="{StaticResource textBlockBase}" Text="{Binding FirstName}" />
</Border>
</GridViewColumn.CellTemplate>
<GridViewColumn.HeaderTemplate>
<!--your header template-->
</GridViewColumn.HeaderTemplate>
</GridViewColumn>
<GridViewColumn>
<GridViewColumn.CellTemplate>
<Border Style="{StaticResource borderBase}">
<TextBlock Style="{StaticResource textBlockBase}" Text="{Binding SecondName}" />
</Border>
</GridViewColumn.CellTemplate>
<GridViewColumn.HeaderTemplate>
<!--your header template-->
</GridViewColumn.HeaderTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
<Grid Style="{StaticResource TableHeader}">
<Grid.Resources>
<Style TargetType="{x:Type Border}" BasedOn="{StaticResource TableBorder}"/>
<Style TargetType="{x:Type TextBlock}" BasedOn="{StaticResource TextTableHeader}">
<Setter Property="TextWrapping" Value="Wrap"/>
</Style>
</Grid.Resources>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Border BorderThickness="1">
<TextBlock Text="Card"/>
</Border>
<Border Grid.Column="1" BorderThickness="0 1 1 1">
<TextBlock Text="Type"/>
</Border>
<Border Grid.Column="2" BorderThickness="0 1 1 1">
<TextBlock Text="Limit"/>
</Border>
<Border Grid.Column="3" BorderThickness="0 1 1 1">
<TextBlock Text="Amount"/>
</Border>
<Border Grid.Column="4" BorderThickness="0 1 1 1">
<TextBlock Text="Payment Due"/>
</Border>
</Grid>
<ListBox Style="{StaticResource ListBoxStyle}"
ItemsSource="{Binding Source}"
SelectedItem="{Binding SelectedItem}"
IsHitTestVisible="{Binding IsSelectionActive}"
ItemTemplate="{Binding ItemTemplate}" />
</Grid>
<ListView ItemsSource="{Binding Source={StaticResource Locator},Path=EtudiantVM.ListEtudiants}">
<ListView.View>
<GridView>
<GridViewColumn Header="Nom" Width="100">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Nom}"></TextBlock>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Prénom" Width="100">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Prenom}"></TextBlock>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Note" Width="100">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Note}"></TextBlock>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
