c# - Make panel scroll horizontally only, not working

Question

I have a panel in the left side that I want it to scroll horizontally only but is not working. I went into the panels properties and set ScrollBars to horizontal and it shows but it does not work. Picture is below.

  <asp:Panel ID="panelButtons" runat="server"  Direction="LeftToRight" 
         CssClass="leftPanel" ScrollBars="Horizontal" ></asp:Panel>

Answer 1

私はcssでこれを行います: http://jsfiddle.net/8HJ4v/

オーバーフロー プロパティは重要な部分です。

overflow-x:scroll;
overflow-y:hidden;

Answer 2

ネストされたパネルを使用して、両方のパネルの幅を明示的に設定しようとしています。

<asp:Panel ID="panelContainer" runat="server"  Direction="LeftToRight" CssClass="leftPanelContainer" ScrollBars="Horizontal" Width="300px;">
  <asp:Panel ID="panelButtons" runat="server"  Direction="LeftToRight" CssClass="leftPanel" ScrollBars="Horizontal" Width="1000px">
    LEFT PANEL
  </asp:Panel>
</asp:Panel>
