TD自己不容許出現滾動條,而會總動撐大,因此要想加滾動條須要另外在TD內添加一個容器如:DIV。spa
例子:server
<table style="width: 450px; height: 360px">
<tr>
<td valign="top" style="border:solid 1px gray"><div style="overflow-y:scroll;height:330px;">
<asp:TreeView ID="TreeView1" runat="server" ExpandDepth="1" OnSelectedNodeChanged="TreeView1_SelectedNodeChanged" ShowCheckBoxes="None" ShowLines="true">
</asp:TreeView></div>
</td>
<td valign="top" style="border:solid 1px gray;"><%--<div style="overflow-y:scroll;height:330px;">--%>
<br />
<asp:Label ID="Label1" runat="server" Text="請選擇人員:"></asp:Label><br />
<asp:Panel ID="Panel1" runat="server" ScrollBars="Auto" Height="300px">
<asp:RadioButtonList ID="RadioButtonList1" runat="server">
</asp:RadioButtonList>
</asp:Panel>
<%--</div>--%></td>
</tr>
<tr>
<td align="center" colspan="2" valign="top" style="height: 30px">
<input id="Button1" type="button" value="肯定" onclick="goback();" /></td>
</tr>
</table>input
