【问题描述】：

目前我有一个 DataGridView（绑定到一个 DataTable）和一些标签。如果DataGridView的事件SelectionChanged发生，标签应该填上选中行的信息->没问题。但是如果我对DataGridView进行排序并单击一行，标签中的信息是错误的。

事件：

Private Sub DGVMain_SelectionChanged(ByVal sender As System.Object, ByVal e As    System.EventArgs) Handles DGVMain.SelectionChanged
    If DGVMain.SelectedRows.Count > 0 AndAlso Not Me.DGVMain Is Nothing Then
        Dim index As Integer = DGVMain.SelectedRows(0).Index

        Dim row As ResultSet.ResultsRow = CType(DGVMain.DataSource, ResultSet.ResultsDataTable).Rows(index)
        SetDetails(row)
    End If
End Sub

设置标签的详细信息：

Private Sub SetDetails(ByVal row As ResultSet.ResultsRow)
    Dim rounding As Integer = 0
    If row.AssayDisplayResultFormat.Contains(":") Then
        rounding = Integer.Parse(row.AssayDisplayResultFormat.Split(":")(1))
    End If
    LBResultValue.Text = Round(row.ResultResultValue * row.AssayDisplayResultFactor, rounding) & " " & row.AssayDisplayResultUnit
    LBAssayNameValue.Text = row.AssayDisplayShortName & " (" & row.AssayOID & ")"
    LBSampleIdValue.Text = row.ResourceName
    LBCreationDateValue.Text = row.ResourceCreated
    LBFlagsValue.Text = ""
    LBRawValue.Text = Round(row.ResultRawValue, rounding) & " " & row.AssayDisplayResultUnit
End Sub

【解决方案1】：

还需要在DataGridView的Sorted事件中设置label的详细信息

        private void DGVMain_Sorted(object sender, EventArgs e)
        {
            SetDetails(dataGridView1.Rows[dataGridView1.SelectedCells[0].RowIndex]);
        }
