我之前从未使用过xslt，现在我想在页面中添加一个下拉列表，并且需要从页面正文中的重复项创建搜索所选值。
我的问题是：
如何在xslt中创建下拉列表。 我尝试过以下链接，但它对我不起作用。 Generate dynamic dropdown in xslt using c#
如何创建将从重复项目中搜索的事件。有什么方法可以调用下拉列表的selectedindex更改事件。
请帮忙。
答案 0 :(得分：0)
你可以创建一个DropDownList
<asp:DropDownList xmlns:asp="System.Web.UI.WebControls" ID="TheDdl" OnSelectedIndexChanged="Selection_Change" runat="server">
<asp:ListItem Value="1" Text="Text 1" />
<asp:ListItem Value="2" Text="Text 2" />
<asp:ListItem Value="3" Text="Text 3" />
</asp:DropDownList>
Code behind看起来像
void Selection_Change(Object sender, EventArgs e)
{
// do something ...
}

Xslt只是将一些源XML转换为一些格式化的文本，通常是HTML或XML。这个你的xslt正在创建html代码，一些＆lt; div class =“offers_section”＆gt;。我看到xslt代码中绑定了一些链接。
生成的这个html代码存储在字符串XSLTOutput.ToString（）中，后者稍后作为文字控件插入到ASP页面中。后面的代码是通过从数据库中检索一些数据来创建源XML文档XDocOffers。
您可以编辑已提供的xslt代码并允许其插入html控件＆lt;选择＆GT;和＆lt;选项＆gt;而不是去asp的＆lt; ASP：下拉列表＆GT;
如果你想使用一些＆lt; ASP：下拉列表＆GT;控制，我想你正在尝试使用XDocOffers作为数据源。如果不是，您必须自己编写代码才能从数据库中进行查询。
您可以运行代码并观看XDocOffers XML文档及其结构。然后，您可以具体询问哪个是您要用作下拉键的成员，哪个是下拉值。并明确了解下拉控件的问题。
