Question

我想在DataGridView中有一个“帮助”光标，但只有第1行到行尾，不包括列标题。我目前使用的代码在datagridview控件上显示帮助光标 - 在列标题上甚至在行下的空白区域，因为我已将datagridview停靠在面板中。这可能很简单，但我该如何解决这个问题呢？我有代码在离开DataGridView时将光标设置回默认值。

Private Sub DataGridView1_CellMouseMove(sender As Object, e As DataGridViewCellMouseEventArgs) Handles DataGridView1.CellMouseMove
    Dim dgv As DataGridView = DataGridView1
    For r As Integer = 1 To dgv.RowCount - 1
        Me.Cursor = Cursors.Help
    Next
End Sub

Private Sub DataGridView1_CellMouseLeave(sender As Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellMouseLeave
    Me.Cursor = Cursors.Default
End Sub

这会将光标更改为仅在单元格上方时才有帮助。它排除了标题行和左列以及背景。您可以根据自己的需要更改条件

Private Sub DataGridView1_MouseMove(sender As Object, e As MouseEventArgs) Handles DataGridView1.MouseMove
    Dim myHitTest = DataGridView1.HitTest(e.X, e.Y)
    If myHitTest.RowIndex >= 0 AndAlso myHitTest.ColumnIndex >= 0 Then
        DataGridView1.Cursor = Cursors.Help
    Else
        DataGridView1.Cursor = Cursors.Default
    End If
End Sub

仅在datagridview行中设置Cursor
