代码运行正常。

    Private Sub dgv_employees_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgv_employees.CellClick
    'If dgv_employees.Columns(e.ColumnIndex).HeaderText = "Edit" Then
    If e.ColumnIndex = 16 Then
        'dgv_employees.Columns(16).SortMode = DataGridViewColumnSortMode.NotSortable
        Dim constr As String = "Data Source=CARSON-PC;Initial Catalog=payroll;Integrated Security=True"
        Dim row As DataGridViewRow = dgv_employees.Rows(e.RowIndex)
        Dim ds As New DataSet()

        If MessageBox.Show(String.Format("Do you want to delete ID: {0}", row.Cells("empNum").Value), "Confirmation", MessageBoxButtons.YesNo) = DialogResult.Yes Then
            Using con As New SqlConnection(constr)
                Using cmd As New SqlCommand("DELETE FROM [dbo].[emp_personal] WHERE empNum = @empNum", con)
                    cmd.CommandType = CommandType.Text
                    cmd.Parameters.AddWithValue("@empNum", row.Cells("empNum").Value)
                    con.Open()
                    cmd.ExecuteNonQuery()
                    con.Close()
                End Using
            End Using

            Me.BindGrid()
        End If

    End If

End Sub

但是，每当我单击列标题时，都会给我一个错误。

我该如何解决？

我认为此问题是由于尝试排序而引起的，我将使用以下代码来禁用对DataGridViewButtonColumns的排序。

 DataGridView.Columns.Item(<columnIndex or "Name">).SortMode = DataGridViewColumnSortMode.Programmatic

可能，您也可以使用Overides禁用标题本身中的click事件：disable-sorting-when-clicking-datagridview-column-header
