DataGrid1鼠标点击事件
有没有这样的事件，在鼠标双击某数据行的时候发生
datagrid.doubleclick事件时只要在控件内双击就会发生，如何判断用户双击位置是在某数据行而不是在caption？

' e.x e.y
Private Function GetRowFromPoint(ByVal x As Integer, ByVal y As Integer, ByVal tg As Windows.Forms.DataGridView) As Integer()
Dim i As Integer
Dim j As Integer
Dim k(2) As Integer
For i = 0 To tg.Rows.Count - 1
For j = 0 To tg.ColumnCount - 1
Dim rec As Drawing.Rectangle
rec = tg.GetCellDisplayRectangle(i, j, True)
If (tg.RectangleToScreen(rec).Contains(x, y)) Then
k(0) = i
k(1) = j
Return k
End If
Next
Next
Return k
End Function
Private Sub DataGridView1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseDoubleClick
If e.Clicks < 2 And e.Button = Windows.Forms.MouseButtons.Left Then
Dim idx() As Integer
idx = GetRowFromPoint(e.X, e.Y, sender)
'idx(0) 为鼠标所在行，'idx(1)为鼠标所在列
'之后代码应该知道怎么写了吧
End If
End Sub

dim fgRow ,fgCol as Integer
fgRow = CType(yourdatagird, DataGird).MouseRow
fgCol = CType(yourdatagird, DataGird).MouseCol
If fgRow > 0 Then
yourdatagird.Select(fgRow, fgCol)
ctxMnuFrom.Show(yourdatagird, New Point(e.X, e.Y))
End If
