c# - 如何获取 GridViewColumnHeader Click 事件上的 ListViewControl

Question

我有 7 个不同的 ListView。

有一个名为 SortClick(object sender, RoutedEventArgs e) 的 Sort 方法 -当单击 GridViewColumnHeader 时，它会引发 SortClick 事件。

但是在这个方法中我必须告诉，哪个ListView应该被排序，b.e

listview2.SortNow();

现在我的问题是，如何从 GridViewColumnHeader (sender) 或 e 获取控件 (ListView)，这可能吗？

ListView XAML 的外观如下:

<ListView ItemsSource="{Binding MissingTables}" Name="missingTablesListView" HorizontalAlignment="Stretch" VerticalAlignment="Top" Margin="0" MinHeight="540" HorizontalContentAlignment="Stretch">
                    <ListView.Background>
                        <ImageBrush />
                    </ListView.Background>
                    <ListView.View>
                        <GridView>
                            <GridViewColumn DisplayMemberBinding="{Binding TableName}" Width="Auto">
                                <GridViewColumnHeader Click="SortClick" Content="TableName" Tag="TableName" ToolTip="Sortieren" />
                            </GridViewColumn>   
                            <GridViewColumn DisplayMemberBinding="{Binding Beschreibung}" Width="Auto">
                                <GridViewColumnHeader Click="SortClick" Content="Description" Tag="Beschreibung" ToolTip="Sortieren" />
                            </GridViewColumn>
                        </GridView>
                    </ListView.View>
                </ListView>

这是 SortClick 代码:

        /// <summary>
        /// Sortiert (Ascending/Descending)
        /// </summary>
        /// <param name="sender">sender</param>
        /// <param name="e">e</param>
        private void SortClick(object sender, RoutedEventArgs e)
        {       
            //ListView listView = sender as ListView;

            GridViewColumnHeader column = sender as GridViewColumnHeader;
            String field = column.Tag as String;

            if (currentSortColumn != null)
            {
                AdornerLayer.GetAdornerLayer(currentSortColumn).Remove(sorter);
                listView.Items.SortDescriptions.Clear();
            }

            ListSortDirection newDir = ListSortDirection.Ascending;
            if (currentSortColumn == column && sorter.Direction == newDir)
            {
                newDir = ListSortDirection.Descending;
            }

            currentSortColumn = column;
            sorter = new Sorter(currentSortColumn, newDir);
            AdornerLayer.GetAdornerLayer(currentSortColumn).Add(sorter);
            listView.Items.SortDescriptions.Add(new SortDescription(field, newDir));
        }

当您说 SortClick 事件时，我不太确定您的意思，但我猜您的意思是附加了 SortClick 处理程序的 GridViewColumnHeader.Click 事件。

如果将 GridViewColumnHeader.Click 添加到 ListView，如下所示:

<ListView GridViewColumnHeader.Click="SortClick">

您将在事件处理程序的 sender 参数中获得 ListView 控件，并在 e.OriginalSource< 中获得 GridViewColumnHeader/.

为了清楚起见，请进行编辑。在您的 SortClick 处理程序中，您将像这样访问该控件:

ListView listView = sender as ListView;
GridViewColumnHeader header = e.OriginalSource as GridViewColumnHeader;
