WPF ListView: Aligning text in selected columns
<ListView ItemsSource="{Binding MyData}">
<ListView.View>
<GridView>
<GridViewColumn Header="col1" DisplayMemberBinding="{Binding Path=value1}">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock TextAlignment="Right" Text="{Binding Path=value1}"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="col2">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock TextAlignment="Center" Text="{Binding Path=value2}"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="col3" DisplayMemberBinding="{Binding Path=value3}"/>
</GridView>
</ListView.View>
<ListView ItemsSource="{Binding MyData}">
col1 is supposed to be right-aligned. (Not working)
col2 is supposed to be center-aligned. (Working) col3 is supposed to be left-aligned. (Working)Is there a reason DisplayMemberBinding is overriding CellTemplate? If so, is there a fix for this (while still using DisplayMemberBinding)?
Edit: I ended up implementing it like this:
<Window xmlns:util="开发者_开发百科clr-namespace:TestProject.Util">
<Window.Resources>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
<Style TargetType="GridViewColumnHeader">
<Setter Property="HorizontalContentAlignment" Value="Left"/>
</Style>
<DataTemplate x:Key="value1Template">
<TextBlock TextAlignment="Right" Text="{Binding Path=value1}"/>
</DataTemplate>
<DataTemplate x:Key="value2Template">
<TextBlock TextAlignment="Right" Text="{Binding Path=value2}"/>
</DataTemplate>
</Window.Resources>
<Grid>
<ListView ItemsSource="{Binding MyData}" IsSynchronizedWithCurrentItem="True" util:GridViewSort.Command="{Binding SortCommand}">
<ListView.View>
<GridView>
<GridViewColumn Header="col1" CellTemplate="{StaticResource value1Template}" util:GridViewSort.PropertyName="value1"/>
<GridViewColumn Header="col2" CellTemplate="{StaticResource value2Template}" util:GridViewSort.PropertyName="value2"/>
</GridView>
</ListView.View>
</ListView>
</Grid>
</Window>
In the code behind:
private RelayCommand sortCommand;
public ICommand SortCommand { get { return sortCommand ?? (sortCommand = new RelayCommand(Sort)); } }
private void Sort(object param)
{
var propertyName = param as string;
var view = CollectionViewSource.GetDefaultView(MyData);
var direction = ListSortDirection.Ascending;
if (view.SortDescriptions.Count > 0)
{
var currentSort = view.SortDescriptions[0];
if (currentSort.PropertyName == propertyName)
direction = currentSort.Direction == ListSortDirection.Ascending ? ListSortDirection.Descending : ListSortDirection.Ascending;
view.SortDescriptions.Clear();
}
if (!string.IsNullOrEmpty(propertyName))
view.SortDescriptions.Add(new SortDescription(propertyName, direction));
}
DisplayMemberBinding
has the highest priority. You can not use it combined with CellTemplate. See here in the remarks section.
If you want to right-or center-align the content, you must declare the CellTemplate
with the binding (as you did) and remove the DisplayMemberBinding
-attribute. If you also want to change the column header alignment, you must also set the GridViewColumn.Header
-property.
Just add the following after your Window tag:
<Window.Resources>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Right" />
</Style>
</Window.Resources>
