WPF数据网格问题

Question

我创建了这个数据网格，一切正常，但有一个恼人的小问题

这是我的数据网格的屏幕截图

但是左边有一个小“柱子”，这让我非常恼火。 这是我的代码:

<Window x:Class="IMDB.ML.Window1"
Name="This"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:dg="http://schemas.microsoft.com/wpf/2008/toolkit"
Title="IMDB.ML" Width="{DynamicResource {x:Static SystemParameters.MaximizedPrimaryScreenWidthKey}}"
Height="{DynamicResource {x:Static SystemParameters.MaximizedPrimaryScreenHeightKey}}"
WindowStartupLocation="CenterScreen" WindowStyle="None">
<Window.Resources>
    <Style x:Key="HeaderTextStyle" TargetType="{x:Type dg:DataGridColumnHeader}">
        <Setter Property="Background" Value="DarkSlateGray" />
        <Setter Property="Foreground" Value="White" />
    </Style>
</Window.Resources>
<Grid>
    <Menu Height="22" Name="TopMenu" FontFamily="Verdana" FontSize="12" VerticalAlignment="Top" Background="DarkSlateGray">
        <Menu.BitmapEffect>
            <DropShadowBitmapEffect />
        </Menu.BitmapEffect>
        <MenuItem Header="_File" Background="Transparent" Foreground="White">
            <MenuItem Header="_Close" Background="DarkSlateGray" Foreground="White" Click="close_Click" />
        </MenuItem>
        <MenuItem Header="_Edit" Background="Transparent" Foreground="White">
        </MenuItem>
    </Menu>
    <dg:DataGrid Background="DarkSlateGray" ItemsSource="{Binding ElementName=This, Path=GameData}" ColumnWidth="*"
          Margin="5,35,5,5" AutoGenerateColumns="False" ColumnHeaderStyle="{StaticResource HeaderTextStyle}">
        <dg:DataGrid.Columns>
            <dg:DataGridTextColumn IsReadOnly="True" Binding="{Binding Title}" Header="Title" />
            <dg:DataGridTextColumn IsReadOnly="True" Width="60"  Binding="{Binding Score}" Header="Score" />
            <dg:DataGridTextColumn IsReadOnly="True" Width="60" Binding="{Binding Year}" Header="Year" />
            <dg:DataGridTextColumn IsReadOnly="True" Binding="{Binding Genre}" Header="Genre" />
            <dg:DataGridHyperlinkColumn IsReadOnly="True" Width="200" Binding="{Binding Link}" Header="Link" />
            <dg:DataGridCheckBoxColumn Width="50" Binding="{Binding Seen}" Header="Seen" />
        </dg:DataGrid.Columns>
    </dg:DataGrid>
</Grid>

有人知道我该如何停止吗？因为它很丑:)

WtFudgeE，

您好，我想我已经找到了解决您问题的方法。您看到的这个“列”实际上并不是一列，它是行的标题。它允许您一次选择整行，并在运行时调整行高。但是，如果这些不是您需要的功能，您只需设置 RowHeaderWidth="0" 即可解决此问题。这是您的更新代码:

<Window x:Class="IMDB.ML.Window1"
Name="This"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:dg="http://schemas.microsoft.com/wpf/2008/toolkit"
Title="IMDB.ML" Width="{DynamicResource {x:Static SystemParameters.MaximizedPrimaryScreenWidthKey}}"
Height="{DynamicResource {x:Static SystemParameters.MaximizedPrimaryScreenHeightKey}}"
WindowStartupLocation="CenterScreen" WindowStyle="None">
<Window.Resources>
    <Style x:Key="HeaderTextStyle" TargetType="{x:Type dg:DataGridColumnHeader}">
        <Setter Property="Background" Value="DarkSlateGray" />
        <Setter Property="Foreground" Value="White" />
    </Style>
</Window.Resources>
<Grid>
    <Menu Height="22" Name="TopMenu" FontFamily="Verdana" FontSize="12" VerticalAlignment="Top" Background="DarkSlateGray">
        <Menu.BitmapEffect>
            <DropShadowBitmapEffect />
        </Menu.BitmapEffect>
        <MenuItem Header="_File" Background="Transparent" Foreground="White">
            <MenuItem Header="_Close" Background="DarkSlateGray" Foreground="White" Click="close_Click" />
        </MenuItem>
        <MenuItem Header="_Edit" Background="Transparent" Foreground="White">
        </MenuItem>
    </Menu>
    <dg:DataGrid Background="DarkSlateGray" ItemsSource="{Binding ElementName=This, Path=GameData}" ColumnWidth="*"
          Margin="5,35,5,5" AutoGenerateColumns="False" RowHeaderWidth="0" ColumnHeaderStyle="{StaticResource HeaderTextStyle}">
        <dg:DataGrid.Columns>
            <dg:DataGridTextColumn IsReadOnly="True" Binding="{Binding Title}" Header="Title" />
            <dg:DataGridTextColumn IsReadOnly="True" Width="60"  Binding="{Binding Score}" Header="Score" />
            <dg:DataGridTextColumn IsReadOnly="True" Width="60" Binding="{Binding Year}" Header="Year" />
            <dg:DataGridTextColumn IsReadOnly="True" Binding="{Binding Genre}" Header="Genre" />
            <dg:DataGridHyperlinkColumn IsReadOnly="True" Width="200" Binding="{Binding Link}" Header="Link" />
            <dg:DataGridCheckBoxColumn Width="50" Binding="{Binding Seen}" Header="Seen" />
        </dg:DataGrid.Columns>
    </dg:DataGrid>
</Grid>

此外，这是我的网格的屏幕截图(显然没有您的网格的数据 - 我使用了一个带有名字和姓氏的简单 Person 对象。):

希望这对您有所帮助，

谢谢!
