Xceed DataGrid中：删除上面详细列间距

问题描述：

如何删除这个间距Xceed之前明细行自动放入？通常这里有一个标题，但我没有设置它，因为我不想要它。标有红色的间距是最烦人的。

我发现，替换这一行：

   <xcdg:DetailConfiguration RelationName="Settings" Title="">

这一行：

  <xcdg:DetailConfiguration RelationName="Settings" Title="" UseDefaultHeadersFooters="False">

将删除标记为红色的空间。但它也删除我的标题：

|名称|说明|编辑值|编辑值|

这里是我的代码：

<UserControl.Resources> 

    <!--#region DataTemplateSelector--> 
    <local:SettingsDataTemplateSelector x:Key="SettingsDataTemplateSelector" /> 

    <DataTemplate x:Key="TextboxDataTemplate">

    </DataTemplate> 

    <DataTemplate x:Key="ComboDataTemplate">

编辑：我想通了，如何摆脱蓝色的间距，但还是无法弄清楚如何摆脱红色的。

代码：

<Style TargetType="xcdg:HierarchicalGroupLevelIndicatorPane" > 
    <Setter Property="MaxWidth" Value="0" /> 
</Style>

你可能会认为你可以添加<Setter Property="MaxHeight" Value="0" />，但什么都不做。

答

蓝色的间距由HierarchicalGroupLevelIndicatorPane，这意味着你可以通过简单的宽度设置为0干掉它设置：

<Style TargetType="xcdg:HierarchicalGroupLevelIndicatorPane" > 
    <Setter Property="MaxWidth" Value="0" /> 
</Style>

红色间隔是有点难度。最后我在DetailConfiguration上设置UseDefaultHeadersFooters为false，这会删除空间，但也会删除ColumnManagerRow。然后我再次在DetailConfiguration.Headers中创建ColumnManagerRow。

的代码看起来是这样的：

 <xcdg:DataGridControl.DetailConfigurations> 
      <xcdg:DetailConfiguration RelationName="Settings" UseDefaultHeadersFooters="False"> 

       <xcdg:DetailConfiguration.Headers> 
        <DataTemplate> 
         <xcdg:ColumnManagerRow /> 
        </DataTemplate> 
       </xcdg:DetailConfiguration.Headers> 

       <xcdg:DetailConfiguration.Columns> 
        <xcdg:Column FieldName="Name" Title="Name" ReadOnly="True" /> 
        <xcdg:Column FieldName="Description" Title="Description" ReadOnly="True" /> 
        <xcdg:Column FieldName="EditValues" Title="Edit Values" ReadOnly="True" /> 
        <xcdg:Column FieldName="EditValueVar" Title="Edit Value" Width="150" ReadOnly="False" 
           CellContentTemplateSelector="{StaticResource SettingsDataTemplateSelector}" 
           DisplayMemberBinding="{Binding}" /> 
        <xcdg:UnboundColumn FieldName=" " /> 
       </xcdg:DetailConfiguration.Columns> 

      </xcdg:DetailConfiguration> 
     </xcdg:DataGridControl.DetailConfigurations>
