在 DataGridView 中获取"current cell"的 X/Y 坐标?



[使用VB 2010/Wforms]

我有一个包含多个列的DataGridView。它是未绑定的,没有连接到任何类型的数据库或任何东西——我只是根据用户输入逐个单元格地填充它。

因此,无论如何,DGV中的一列的类型是"image"(DataGridViewImageColumn)。

我想做的是,每当单击其中一个图像单元格时,就会在单击图像单元格的确切位置显示上下文菜单条。

以下是我目前所掌握的。。。

Private Sub DataGridView1_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick
        Dim columnName As String = DataGridView1.Columns(e.ColumnIndex).Name
        If columnName = "Image" Then 
         Me.Status_ContextMenuStrip1.Show(Me.DataGridView1.CurrentCell.ContentBounds.Location) ' <-- This isn't right, but I must be close!
        End If
End Sub

当我运行上面的代码并单击图像单元格时,会出现上下文菜单,但它会出现在屏幕的左上角。如何使其显示在单击单元格所在的确切位置?实际上,我希望它出现在单击的单元格下方,这样它就有了类似于组合框"下拉"的视觉效果(我知道如何在大致接近它需要的位置时偏移X和Y坐标)。

谢谢!

尝试以下代码

Private Sub DataGridView1_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick
    Dim columnName As String = DataGridView1.Columns(e.ColumnIndex).Name
    If columnName = "Image" Then
        Dim RowHeight1 As Integer = DataGridView1.Rows(e.RowIndex).Height
        Dim CellRectangle1 As Rectangle = DataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, False)
        CellRectangle1.X += DataGridView1.Left
        CellRectangle1.Y += DataGridView1.Top + RowHeight1
        Dim DisplayPoint1 As Point = PointToScreen(New Point(CellRectangle1.X, CellRectangle1.Y))
        ContextMenuStrip1.Show(DisplayPoint1)
    End If
End Sub

对于任何在未来与之斗争的人来说,这才是真正有效的:

'For forms
Dim f as New Form2
f.Location = DGV.PointToScreen(DGV.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, False).Location)

对于这篇文章:

Private Sub DataGridView1_CellClick(ByVal sender As System.Object, ByVal e As
  Dim DisplayPoint1 As Point = DGV.PointToScreen(DGV.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, False).Location)
ContextMenuStrip1.Show(DisplayPoint1)
End Sub

尝试这样更改代码。。

Private Sub DataGridView1_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick
    Dim columnName As String = DataGridView1.Columns(e.ColumnIndex).Name
    If columnName = "Image" Then 
       DataGridView1.CurrentCell = dgvDataDaftar.Rows(e.RowIndex).Cells(e.ColumnIndex)
       Me.Status_ContextMenuStrip1.Show(dgvDataDaftar, DataGridView1.PointToClient(Windows.Forms.Cursor.Position))
    End If
End Sub
