DataGridView select Row
提问by user2195966
I want to select a row in my DataGridView with a right click. But with my current code I first have to click on the row with a regular left mouse click.
我想通过右键单击在我的 DataGridView 中选择一行。但是对于我当前的代码，我首先必须通过常规的鼠标左键单击来单击该行。
Is there any way to select the current row with a right click and than open a ContextMenuStrip?
有没有办法通过右键单击选择当前行而不是打开 ContextMenuStrip？
Private Sub DataGridView1_CellMouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.CellMouseDown
If e.Button = Windows.Forms.MouseButtons.Right AndAlso e.RowIndex >= 0 Then
Me.DataGridView1.CurrentCell = Me.DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex)
End If
End Sub
Private Sub datagridview1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseDown
If e.Button = Windows.Forms.MouseButtons.Right Then
Dim hti As DataGridView.HitTestInfo = sender.HitTest(e.X, e.Y)
If hti.Type = DataGridViewHitTestType.Cell Then
If Not DataGridView1.Rows(hti.RowIndex).Selected Then
DataGridView1.ClearSelection()
DataGridView1.Rows(hti.RowIndex).Selected = True
End If
End If
End If
End Sub

Try this:
尝试这个：
Private Sub DataGrid1_CellMouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)
On Error Resume Next
If e.Button = MouseButtons.Right Then
'Clear previous selections
For x As int32 = 0 To ds.Tables(0).Rows.Count() - 1
DataGrid1.UnSelect(x)
Next x
'select row under mouse click
Dim info As DataGrid.HitTestInfo = DataGrid1.HitTest(e.X, e.Y)
If info.Row > -1 Then
DataGrid1.CurrentRowIndex = info.Row
DataGrid1.Select(info.Row)
Application.DoEvents()
DataGridContextMenu.Show(Cursor.Position)
End If
info = Nothing
End If
End Sub
