如何在控件模板的WPF中为ListView列应用MinWidth? [英] How apply MinWidth for ListView columns in WPF in control template?

问题描述

在此处的类似问题的答案之后，我能够在XAML页面上设置MinWidth.

Following the answer to a similar question here, I was able to set the MinWidth on the XAML page.

我想做的是在所有ListView的所有GridViewColumn的控件模板中完成此操作.

What I would like to do is accomplish this in the control template for all GridViewColumn's in all ListView's.

这可能吗?

更新:

我在下面尝试了一些简单的示例代码，但是它不起作用:

I tried a simple bit of sample code below, but it does not work:

<Window x:Class="WpfApplication4.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">

    <Window.Resources>
        <Style TargetType="{x:Type GridViewColumnHeader}" >
            <Setter Property="MinWidth" Value="200" />
        </Style>
    </Window.Resources>

    <Grid Width="500">
        <Border BorderBrush="Black" BorderThickness="2" Margin="20">
            <ListView SelectionMode="Single">
                <ListView.View>
                    <GridView>
                        <GridViewColumn Header="Header 1" Width="Auto">
                            <GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <TextBlock Text="Hello There"/>
                                </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Header 2" Width="Auto" />
                    </GridView>
                </ListView.View>
            </ListView>
        </Border>
    </Grid>
</Window>

推荐答案

如果使用GridViewColumnHeader，则可以处理大小更改:

If you use a GridViewColumnHeader you can handle size changes:

  <GridView>
     <GridViewColumn>
        <GridViewColumnHeader Content="HeaderContent" SizeChanged="HandleColumnHeaderSizeChanged"/> 
   ...

使用代码:

    private void HandleColumnHeaderSizeChanged(object sender, SizeChangedEventArgs sizeChangedEventArgs)
    {
        if (sizeChangedEventArgs.NewSize.Width <= 60) {
            sizeChangedEventArgs.Handled = true;
            ((GridViewColumnHeader) sender).Column.Width = 60;
        }
    }
