如何改变列表框的asp.net中选定的颜色 [英] how to change the selected color of listbox in asp.net

问题描述

<asp:ListBox 
     ID="ddlPA" 
     ClientIDMode="Static" 
     runat="server" 
     AutoPostBack="true"
     SkinID="x" 
     CssClass="ListBoxCssClass" 
     SelectionMode="Multiple" 
     OnSelectedIndexChanged="ddlPA_SelectedIndexChanged">
</asp:ListBox>

当我选择ASP项目：列表框，选择的项目颜色变为灰色，我想改变颜色为蓝色。
 我怎么可以这样做？

When i select an item in asp:listbox , the selected item color changes to gray, i want to change the color to blue. how can i do the same?

推荐答案

您可以通过指定CssClass属性，或者背景色属性设置在.aspx页面中的背景颜色..它看起来像：

You can set background colors from the .aspx page by specifying either the CssClass, or the BackColor property.. it looks like:

<asp:ListBox CssClass="MyListBox" BackColor="#e0e0e0"></asp:ListBox>

设置所选的项目是有点麻烦...我不相信这是直接针对于此的属性。你可以将其设置成JavaScript或jQuery的，是这样的：

Setting the selected item is a little trickier... I don't believe there is an attribute for this directly. You can set it in javascript, or jQuery, something like:

<script type="text/javascript">
  $(document).ready(function() {
    $('#MyListBox').click(function() {
        $("#MyListBox option:selected").css("background-color", "#e0e0e0");
    }); 
  });
</script>
