Datagridview - 专注于右键单击的Cell

Question

我有一个datagridview,我已经打开了ContextMenuStrip1.我想在右键单击行时删除datagridview中的一行,然后单击"删除行".我有删除工作,菜单显示,但是当您右键单击datagridview时,这不会触发.

这是我设置要编辑的行的位置:

   Private Sub ModifyRowToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ModifyRowToolStripMenuItem.Click
    If Not datagridview_TagAssignment.CurrentRow Is Nothing Then
      datagridview_TagAssignment.CurrentCell = datagridview_TagAssignment.Item(0, datagridview_TagAssignment.CurrentRow.Index)
      datagridview_TagAssignment.BeginEdit(True)
    End If
  End Sub

我总是以行(0)结束,而不是我右键单击的行.

 Private Sub datagridview_TagAssignment_CellMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles datagridview_TagAssignment.CellMouseClick
    If e.Button = Windows.Forms.MouseButtons.Right AndAlso e.RowIndex >= 0 Then
      datagridview_TagAssignment.Rows(e.RowIndex).Selected = True
    End If
  End Sub

有人有什么建议吗？

Private Sub DataGridView1_MouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseClick
    If e.Button = Windows.Forms.MouseButtons.Right Then
        rowClicked = DataGridView1.HitTest(e.Location.X, e.Location.Y).RowIndex
        ContextMenuStrip1.Items.Add(rowClicked.ToString)
        ContextMenuStrip1.Show(DataGridView1, e.Location)
        ContextMenuStrip1.Items.Clear()
    End If
End Sub

编辑:已更新以处理上下文菜单条.

这应该为您提供使用鼠标坐标右键单击的行的行索引.哪个应该让你基于知道索引删除行.

根据你对它的评论不起作用,这是我的代码

我有一个WinForm的解决方案,添加了一个dataGridView.这是表单中的代码.

Public Class Form1

    Dim bindS As New BindingSource
    Dim rowClicked As Integer
    Private Sub DataGridView1_MouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseClick
        If e.Button = Windows.Forms.MouseButtons.Right Then
            rowClicked = DataGridView1.HitTest(e.Location.X, e.Location.Y).RowIndex
            ContextMenuStrip1.Items.Add(rowClicked.ToString)
            ContextMenuStrip1.Show(DataGridView1, e.Location)
            ContextMenuStrip1.Items.Clear()
        End If

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim s As New List(Of String)
        s.Add("String one")
        s.Add("String Two")
        bindS.DataSource = s
        DataGridView1.DataSource = bindS


    End Sub
End Class

右键单击一行显示正确的行索引

确保您正在处理的事件args是System.Windows.Forms.MouseEventArgs我注意到您正在处理单元格单击
