Question

是否可以将 XCeed DataGrid控件 中的过滤器行拉出到其他位置（如组框）？如果可能，怎么样？任何指针都将受到赞赏。

请考虑以下情况，当我点击 过滤器 按钮时， 产品名称 列将被过滤根据过滤查询。为了完成这个场景，我需要为 产品名称 取出FilterRow Cell。

您可以获得一个完整的示例，它可以在Xceed DataGrid附带的演示文件中准确显示您需要的内容。

硬盘上的默认位置是：

External Auto Filter Control C：\ Xceed Samples \ Xceed DataGrid for WPF Professional Edition v4.2 \ CSharp \ CustomFiltering

这是一个代码片段，显示如何使用AutoFilterControl执行此操作，该AutoFilterControl绑定到您需要的相应DataGrid列。

<GroupBox x:Name="groupBox" Header="Auto-filter Actions"
                  Margin="{StaticResource groupBoxMargin}"
                  Padding="{StaticResource groupBoxPadding}"
                  Grid.Column="0">
           <StackPanel x:Name="stackPanel">
              <!-- ComboBoxes for automatic filtering -->
              <Grid Grid.Column="2"
                    HorizontalAlignment="Right">
                 <Grid.ColumnDefinitions>
                    <ColumnDefinition />
                    <ColumnDefinition Width="135" />
                    <ColumnDefinition />
                 </Grid.ColumnDefinitions>

                 <Grid.RowDefinitions>
                    <RowDefinition MinHeight="30" />

                                 AutoFilterContext="{Binding ElementName=grid, Path=(xcdg:DataGridControl.DataGridContext)}"
                                 Focusable="False"
                                 Width="Auto">

Answer 2

是的，这是可能的！查看xceed datagrid文档！ http://doc.xceedsoft.com/products/XceedWpfDataGrid/ 很抱歉，我无法找到任何直接链接，因此您必须从左侧面板导航： XCeed DataGrid for WPF-＆gt; DataGrid Foundamentals-＆gt; Manipulating Data-＆gt; Filtering Data

Answer 3

在DataGridControl定义的XAML中查找FilterRow并删除。

<xcdg:DataGridControl ... > 
  <DataTemplate>
    <xcdg:FilterRow Background="Pink" />
  </DataTemplate>
</xcdg:DataGridControl>

从XCeed DataGrid控件中取出FilterRow
