如何及时获得datagrid中单元格里改变后的内容

  一般想要及时得到单元格中内容发生改变是的内容，用

        Dim singleCol As New DataGridTextBoxColumn        AddHandler singleCol.TextBox.Leave, New EventHandler(AddressOf Refresh_paradata) 

       Private Sub Refresh_paradata(ByVal sender As Object, ByVal e As System.EventArgs)                 dim  temp as string

                icol= dg.CurrentCell.ColumnNumber

                 irow= dg.CurrentCell.rowNumber

                temp = dg.item(irow,icol)        

        htRib.Add(iCol, CType(sender, TextBox).Text.Trim)    End Sub

但实际中我们并不能得到我们想要的值，因为这时item中的值还未发生改变。

要改为：

  Private Sub Refresh_paradata(ByVal sender As Object, ByVal e As System.EventArgs)                 dim  temp as string

               temp = CType(sender, TextBox).Text.Trim

            End Sub

就可以了
