[英]WPF DataGrid Column Header Resize with Custom Style
I have a WPF DataGrid (.NET 4) with custom template columns and header styles and would like to be able to adjust the size of the columns : 我有一个带有自定义模板列和标题样式的WPF DataGrid(.NET 4),并希望能够调整列的大小:
<DataGridTemplateColumn.HeaderStyle>
<Style TargetType="DataGridColumnHeader">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="DataGridColumnHeader">
<StackPanel Orientation="Horizontal">
<Image Source="Images\monitor.png" Width="16" Height="16"/>
<TextBlock Text="Hostname" TextWrapping="Wrap" Padding="3"/>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</DataGridTemplateColumn.HeaderStyle>
Columns can still be sorted and re-arranged but not resized - the gripper does not show. 列仍然可以进行排序和重新排列,但不会调整大小 - 夹子不会显示。 I have seen this answer and looked at the Thumb control, however this seems like massive overkill to reproduce functionality already provided.
我已经看到了这个答案并查看了Thumb控件,但是这似乎是重复已经提供的功能的过度杀伤。 The MSDN blog post references a StaticResource - RowHeaderGripperStyle which they don't provide!
MSDN博客文章引用了一个他们没有提供的StaticResource - RowHeaderGripperStyle!
I always do it this way and it works pretty fine: 我总是这样做,它工作得很好:
<Style TargetType="DataGridColumnHeader">
<!-- here goes some setters -->
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="DataGridColumnHeader">
<Grid Margin="{TemplateBinding Padding}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<!-- some stuff, like border etc. -->
<ContentPresenter />
<Thumb x:Name="PART_RightHeaderGripper" Grid.Column="1"
HorizontalAlignment="Right"
Width="2" BorderThickness="1"
BorderBrush="{Binding VerticalGridLinesBrush, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGrid}}}"
Cursor="SizeWE"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
