how to locate the position of a context menu strip on mouse click

推荐答案

通常相对于特定控件显示 - 它只是抵消它的情况（如果你愿意）通过手动构建它并使用Show方法从相关控件的左上角开始一个数量：MSDN有一个例子： http://msdn.microsoft.com/en-us/library/s00cc2f3.aspx [ ^ ]

It is normally shown relative to a particular control - it's just a case of offsetting it (if you want to) by an amount from the top left hand corner of the relevant control by manually constructing it and using the Show method: MSDN has an example: http://msdn.microsoft.com/en-us/library/s00cc2f3.aspx[^]

这应该可以解决问题...

This should do the trick...

Me.ContextMenuStrip1.Bounds.Location

Private Sub Form1_MouseDoubleClick(sender As System.Object, e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDoubleClick
        Me.ContextMenuStrip1.Show(MousePosition)
    End Sub

    Private Sub TestToolStripMenuItem_Click(sender As System.Object, e As System.EventArgs) Handles TestToolStripMenuItem.Click
        MessageBox.Show(Me.ContextMenuStrip1.Bounds.Location.X & "x" & Me.ContextMenuStrip1.Bounds.Location.Y & _
                        vbCrLf & MousePosition.X & "x" & MousePosition.Y)

在 DataGridView

In DataGridView

Private Sub YourDataGrid_CellMouseDown(sender As Object, e As DataGridViewCellMouseEventArgs) Handles YourDataGrid.CellMouseDown
        If e.Button = Windows.Forms.MouseButtons.Right AndAlso e.RowIndex >= 0 Then
            YourDataGrid.Rows(e.RowIndex).Selected = True
            'if possible insert code here to read selected option from context menu and get relevant content from respective cell

            YourContextMenu.Show(MousePosition.X, MousePosition.Y)
        End If
    End Sub
