是否有一个datagrid鼠标按下命中测试来获取点击的行和列索引？

Question

使用Winforms'DataGridView，可以使用HitTest来确定鼠标向下（和其他事件）的列和行索引。

Dim hti As DataGridView.HitTestInfo = sender.HitTest(e.X, e.Y) 

是否有类似WPF的DataGrid？我需要获取MouseLeftButtonDown事件的行和列索引。

Answer 1

这比这更复杂，但以下链接应该有助于获取行和列的索引。

WPF DataGrid - get row number which mouse cursor is on

你将不得不使用VisualTreeHelper类遍历视觉元素组成的DataGrid作为如上所述。

Answer 2

对于那些可能希望避免在这里我的搜索是总的代码，我结束了令人费解在一起能够提供：

1. 当前行的索引
2. 当前列指数
3. 当前列头并且

4. 能够暴露行上列的值。

   的代码进入的MouseLeftButtonUp事件和DGrid1是

   Dim currentRowIndex As Integer = -1 
   Dim CurrentColumnIndex As Integer = -1 
   Dim CurrentColumnHeader As String = "" 
   Dim Myrow As DataRowView = Nothing 
   Dim dep As DependencyObject = DirectCast(e.OriginalSource, DependencyObject) 
   While dep IsNot Nothing And Not TypeOf dep Is DataGridCell And Not TypeOf dep Is Primitives.DataGridColumnHeader 
       dep = VisualTreeHelper.GetParent(dep) 
       If dep IsNot Nothing Then 
        If TypeOf dep Is DataGridCell Then 
         Dim cell As DataGridCell = DirectCast(dep, DataGridCell) 
         Dim col As DataGridBoundColumn = DirectCast(cell.Column, DataGridBoundColumn) 
         Myrow = DGrid1.SelectedItem 
         CurrentColumnHeader = col.Header.ToString 
         CurrentColumnIndex = col.DisplayIndex 
         currentRowIndex = DGrid1.Items.IndexOf(DGrid1.CurrentItem) 
         Exit While 
        End If 
       End If 
   End While 
   If currentRowIndex = -1 OrElse CurrentColumnIndex = -1 OrElse CurrentColumnHeader = "" OrElse Myrow Is Nothing Then Exit Sub 
   
       'code to consume the variables from here 
   
   Dim strinwar As String = Myrow.Item("header name or index").ToString()
