Xceed DataGrid：删除详细信息行上方的间距

Question

如何删除 Xceed 在详细信息行之前自动放置的间距？通常这里有一个标题，但我将其设置为空，因为我不想要它。标红的间距最烦人

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 space。但是它也删除了我的 header:

|名称 |说明 |编辑值 |编辑值 |

这是我的代码：

<UserControl.Resources>

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

    <DataTemplate x:Key="TextboxDataTemplate">
        <xcdg:MaskedTextBox IsTabStop="True" Mask="{Binding EditMask}" Text="{Binding EditValue, IsAsync=False, Mode=TwoWay, UpdateSourceTrigger=LostFocus, ValidatesOnExceptions=True}"/>
    </DataTemplate>

    <DataTemplate x:Key="ComboDataTemplate">
        <ComboBox IsTabStop="True"  ItemsSource="{Binding Path=SelectionValues}"
                                    SelectedValuePath="Value"
                                    SelectedValue="{Binding Path=SelectionValue, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                                    DisplayMemberPath="ValueText">
        </ComboBox>
    </DataTemplate>

    <DataTemplate x:Key="SliderDataTemplate">
        <Slider IsTabStop="True" Value="{Binding EditSliderValue, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                    Minimum="{Binding MinRangeValue}" 
                    Maximum="{Binding MaxRangeValue}"

                    Margin="0,0,0,0"/>
    </DataTemplate>
    <!--#endregion-->

编辑：我想出了如何摆脱蓝色间距，但仍然无法弄清楚如何摆脱红色。

代码：

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

您可能认为可以添加 <Setter Property="MaxHeight" Value="0" />，但这没有任何作用。

Answer 1

蓝色间距由 HierarchicalGroupLevelIndicatorPane 设置，这意味着您只需将宽度设置为 0 即可摆脱它：

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

红色间距有点难。最后，我在 DetailConfiguration 上将 UseDefaultHeadersFooters 设置为 false，这会删除 space，但也会删除 ColumnManagerRow。然后我在 DetailConfiguration.Headers 中再次创建 ColumnManagerRow。

代码如下所示：

       <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>
