Datagrid行选择事件，WPF

【中文标题】Datagrid行选择事件，WPF

【英文标题】：Datagrid row selection event, WPF

【发布时间】：2014-03-18 22:22:54

【问题描述】：

我对数据网格做了一个简单的数据绑定。现在我想在数据网格中单击行时获取相关的行数据（整行数据）。由于没有行选择事件，我是否需要使用 mouseclickevent？。

【参考方案1】：

private void dataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e)

    ProductItem productItem = (ProductItem)dataGrid.SelectedItem; //Datagrid bound with ProductItem 

【参考方案2】：

我是这样做的。其他人可能有更简单的方法！我的处理媒体播放器的 PlayListEntries 类的可观察集合。希望这可以帮助

    private void PlayList_OnMouseLeftButtonUp(object sender, MouseButtonEventArgs e)
    
        DependencyObject dep = (DependencyObject)e.OriginalSource;

        // iteratively traverse the visual tree
        while ((dep != null) && !(dep is DataGridCell) && !(dep is DataGridColumnHeader))
        
            dep = VisualTreeHelper.GetParent(dep);
        

        if (dep == null)
            return;

        if (dep is DataGridColumnHeader)
        
            DataGridColumnHeader columnHeader = dep as DataGridColumnHeader;
            // do something
        

        if (dep is DataGridCell)
        
            DataGridCell cell = dep as DataGridCell;

            // navigate further up the tree
            while ((dep != null) && !(dep is DataGridRow))
            
                dep = VisualTreeHelper.GetParent(dep);
            

            DataGridRow row = dep as DataGridRow;

            var ple = (PlayListEntry)row.Item;

// From here you have access to all of the row.  
// Each column is suitable bound. 
// I can post the xaml if you are not sure.

            //object value = ExtractBoundValue(row, cell);  //4

            //int columnIndex = cell.Column.DisplayIndex;
            //int rowIndex = FindRowIndex(row);

            //var s = string.Format("Cell clicked [0, 1] = 2",rowIndex, columnIndex, value.ToString());
