我有一個帶有背景圖像的頁面上的MultiHandleSliderExtender控件。該控件以純白色背景呈現。我怎樣才能讓它透明?如何使MultiHandleSliderExtender透明?
下面的代碼:
<table>
<tr>
<td>
<asp:TextBox ID="probabilityFilterStartTextBox" runat="server" Width="30" Text="0"></asp:TextBox>
</td>
<td width="200" valign="top">
<asp:TextBox ID="probabilityTextBox" runat="server" Style="display:none;"></asp:TextBox>
<asp:MultiHandleSliderExtender ID="probabilityTextBox_MultiHandleSliderExtender"
runat="server" Enabled="True"
HandleAnimationDuration="0.1" Maximum="100" Minimum="0"
Length="200" TargetControlID="probabilityTextBox" Steps="21">
<MultiHandleSliderTargets>
<asp:MultiHandleSliderTarget ControlID="probabilityFilterStartTextBox" />
<asp:MultiHandleSliderTarget ControlID="probabilityFilterEndTextBox" />
</MultiHandleSliderTargets>
</asp:MultiHandleSliderExtender>
</td>
<td>
<asp:TextBox ID="probabilityFilterEndTextBox" runat="server" Width="30" Text="100"></asp:TextBox>
</td>
</tr>
</table>
我不明白這將如何幫助我使渲染控件透明。 – Henrik
