Silverlight 3 Datagrid：在MouseOver上获取行/项 [英] Silverlight 3 Datagrid: Get row/item on MouseOver

问题描述

我有一个绑定的DataGrid和各种其他控件（在datagrid外部），显示有关datagrid中的被选中的更多细节。这很容易在数据绑定或处理Datagrid上的SelectionChanged事件。

但是，如何在不需要用户选择行的情况下执行此操作 - 例如鼠标悬停我可以更改所选项目，或者获取鼠标下的行/项目。

解决方案

吉姆答案的通用性较差。在VB.Net中：

  Private Sub DataGrid1_LoadingRow（ByVal sender As Object，ByVal e As System.Windows.Controls.DataGridRowEventArgs）句柄DataGrid1.LoadingRow 
 AddHandler e.Row.MouseEnter，AddressOf row_MouseEnter 
 End Sub 
 
 Private Sub row_MouseEnter（ByVal sender As Object，ByVal e As MouseEventArgs）
 Dim row = CType（sender，DataGridRow）
 Me.DataGrid1.SelectedItem = CType（row.DataContext，MyType）
 End Sub 
  

I have a bound DataGrid and various other controls(external to the datagrid) that show more details about the selectedrow in the datagrid. This is easy to do with databinding or handling the SelectionChanged event on the datagrid.

However, how do I do this without requiring the user to select a row - eg on 'mouseover' can I change the selected item or get the row/item 'under' the mouse.

解决方案

Here is a simpler but less generic implementation of Jim's answer. In VB.Net:

Private Sub DataGrid1_LoadingRow(ByVal sender As Object, ByVal e As System.Windows.Controls.DataGridRowEventArgs) Handles DataGrid1.LoadingRow
    AddHandler e.Row.MouseEnter, AddressOf row_MouseEnter
End Sub

Private Sub row_MouseEnter(ByVal sender As Object, ByVal e As MouseEventArgs)
        Dim row = CType(sender, DataGridRow)
        Me.DataGrid1.SelectedItem = CType(row.DataContext, MyType)
End Sub
