无法将溢出属性添加到 ASP.NET 日历中某一天的单元格

问：

我不知道为什么，但是，当我在日历的特定日期添加一些标签时，单元格高度变得比我在 css 中放置的要大。首先，我尝试将值连接起来，并将其放在一个标签中，然后将其添加到当天的单元格中，但没有结果。因此，现在我正在为当天单元格中网格视图中的每一行添加一个标签。

我的 vb 代码中的事件处理程序：Dayrender

Protected Sub Calendar1_DayRender(sender As Object, e As DayRenderEventArgs)
    e.Cell.CssClass = "DayCellStyle"
    'To Show the Po
    Dim aLabel As Label = New Label()
    Dim ADate As Date = e.Day.Date
    For i As Integer = 0 To GridView1.Rows.Count - 1
        Dim PoDate As Date = GridView1.Rows(i).Cells(7).Text
        If ADate = PoDate Then
            Dim PoNo = GridView1.Rows(i).Cells(0).Text
            Dim PoLocationCode As String = GridView1.Rows(i).Cells(1).Text
            Dim PoPayToName As String = GridView1.Rows(i).Cells(2).Text
            Dim PoItemNo As String = GridView1.Rows(i).Cells(3).Text
            Dim PoDescription As String = GridView1.Rows(i).Cells(4).Text
            Dim PoQuantity = Math.Round(Convert.ToDecimal(GridView1.Rows(i).Cells(5).Text), 2)
            Dim PoUnitMeasureCode As String = GridView1.Rows(i).Cells(6).Text
            aLabel.Text = aLabel.Text + "<br>" + "<br>" + "-" + PoNo + " = " + PoLocationCode + " / " + PoPayToName + " ( " + PoItemNo + " / " + PoDescription + " ) " + PoQuantity.ToString + " * " + PoUnitMeasureCode
            e.Cell.Controls.Add(aLabel)
        End If
    Next
    'To Show the TR
    For j As Integer = 0 To GridView2.Rows.Count - 1
        Dim TrDate As Date = GridView2.Rows(j).Cells(8).Text
        If ADate = TrDate Then
            Dim TrNo = GridView2.Rows(j).Cells(0).Text
            Dim TrFromCode = GridView2.Rows(j).Cells(1).Text
            Dim TrToCode = GridView2.Rows(j).Cells(2).Text
            Dim TrItemNo = GridView2.Rows(j).Cells(3).Text
            Dim TrItem2No = GridView2.Rows(j).Cells(4).Text
            Dim TrDescription = GridView2.Rows(j).Cells(5).Text
            Dim TrQuantity = Math.Round(Convert.ToDecimal(GridView2.Rows(j).Cells(6).Text), 2)
            Dim TrUnitOfMeasureCode = GridView2.Rows(j).Cells(7).Text

            Dim bLabel As Label = New Label()
            bLabel.Text = bLabel.Text + "<br>" + "<br>" + "-" + TrNo + " = " + TrFromCode + " / " + TrToCode + " ( " + TrItemNo + " / " + TrItem2No + " (" + TrDescription + ")) " + TrQuantity.ToString + " * " + TrUnitOfMeasureCode
            bLabel.Font.Size = FontUnit.Point(5)
            e.Cell.Controls.Add(bLabel)
        End If
    Next
End Sub

还有我的CSS

body {
}

.PanelCalendar{
    margin: 0% -15% 0% -15%;
}
.DayStyle {
    padding: 10px;
    height: 141px;
    max-height: 141px;
    overflow: auto;
}

.aLabelStyle {
    padding: 10px;
    font-weight: bold;
    height: 141px;
    overflow: auto;
}

.DayCellStyle {
    height: 141px;
    padding: 10px;
    font-weight: bold;
    font-size: 10px;
    overflow: auto;
}

我只希望一天的高度为 141px，如果单元格中的标签超过高度，则添加一个滚动条。
