Datagridview - Focus on Cell that was right clicked
提问by ErocM
I have a datagridview that I have put a ContextMenuStrip1 on. I would like it to remove a row in the datagridview when the row is right clicked on and they click on "delete row". I have the delete working and the menu is showing up but this isn't firing when you right click on the datagridview.
我有一个 datagridview，我已经把 ContextMenuStrip1 放在上面。当右键单击该行并单击“删除行”时，我希望它删除 datagridview 中的一行。我有删除工作并且显示菜单但是当您右键单击数据网格视图时这不会触发。
This is where I am setting the row to edit:
这是我设置要编辑的行的地方：
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
I am always ending up on row(0) and never the row I right clicked on.
我总是在第（0）行结束，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
Anyone have any suggestions?
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
Edit: Updated to handle a context menu strip.
编辑：更新以处理上下文菜单条。
That should give you the row index of the row that was right clicked using the mouse coordinates. Which should let you delete the row based on knowing the index.
这应该为您提供使用鼠标坐标右键单击的行的行索引。这应该让您根据知道索引删除行。

Per Your comment on it not working this is my code
根据您对它的评论不起作用，这是我的代码
I have a Solution with a WinForm with a dataGridView added to it. and this is the code in the form.
我有一个带有 WinForm 的解决方案，其中添加了 dataGridView。这是表格中的代码。
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
Right Clicking on a row shows the correct row index
右键单击一行显示正确的行索引
Make sure that the event args that you are handling are the System.Windows.Forms.MouseEventArgsI noticed that you're handling the cell click
确保您正在处理的事件参数是System.Windows.Forms.MouseEventArgs我注意到您正在处理单元格单击
