WPF DataGrid的列标题样式设计

能够换行

1.定义列样式

  <DataTemplate x:Key="HeaderTemplateCenterAlign">
            <Border>
                <TextBlock TextWrapping="Wrap" Text="{Binding Path=Content, RelativeSource={RelativeSource Mode=TemplatedParent}}"/>
            </Border>
        </DataTemplate>

2.在列样式中使用

  <DataGrid  Style="{x:Null}" ColumnWidth="80" CanUserSortColumns="True" CanUserAddRows="False" AutoGenerateColumns="False"
                  ItemsSource="{Binding Path=TargetModels}">
            <DataGrid.Columns>
                <DataGridTextColumn HeaderTemplate="{StaticResource HeaderTemplateCenterAlign}" IsReadOnly="True" Header="目标ID" Binding="{Binding ID}"/>
                <DataGridTextColumn HeaderTemplate="{StaticResource HeaderTemplateCenterAlign}" IsReadOnly="True" CanUserSort="True" x:Name="ss" SortDirection="Ascending" Header="纵向距离" Binding="{Binding DistLong}"/>
                <DataGridTextColumn HeaderTemplate="{StaticResource HeaderTemplateCenterAlign}" IsReadOnly="True" Header="横向距离" Binding="{Binding DistLat}"/>
                <DataGridTextColumn HeaderTemplate="{StaticResource HeaderTemplateCenterAlign}" IsReadOnly="True" Header="纵向速度" Binding="{Binding VrelLong}"/>
                <DataGridTextColumn HeaderTemplate="{StaticResource HeaderTemplateCenterAlign}" IsReadOnly="True" Header="横向速度" Binding="{Binding VrelLat}"/>
                <DataGridTextColumn HeaderTemplate="{StaticResource HeaderTemplateCenterAlign}" IsReadOnly="True" Header="车长" />
                <DataGridTextColumn HeaderTemplate="{StaticResource HeaderTemplateCenterAlign}" IsReadOnly="True" Header="车道" />
                <DataGridTextColumn HeaderTemplate="{StaticResource HeaderTemplateCenterAlign}" IsReadOnly="True" Header="车真实速度" />
                <DataGridTextColumn HeaderTemplate="{StaticResource HeaderTemplateCenterAlign}" IsReadOnly="True" Header="经度" />
                <DataGridTextColumn HeaderTemplate="{StaticResource HeaderTemplateCenterAlign}" IsReadOnly="True" Header="纬度" />
               
            </DataGrid.Columns>
        </DataGrid>

实时排序

                    ICollectionView view = CollectionViewSource.GetDefaultView(dg.ItemsSource);
                   view.SortDescriptions.Clear();
                  SortDescription sd = new SortDescription("DistLong", ListSortDirection.Descending);
                    view.SortDescriptions.Add(sd);
