我正在研究使用xslt文件显示重复项目的项目。如下:

我以前从未使用过xslt，现在我想向页面添加下拉列表，并且需要从页面正文中的重复项中创建对所选值的搜索。
我的问题是:
如何在xslt中创建下拉列表。我试过下面的链接，但它不适合我。使用c#
在xslt中生成动态下拉列表如何创建一个事件，将搜索从重复的项目。有什么方法可以让我调用下拉菜单的selectedindex更改事件?
请帮。
您可以创建一个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。你的xslt正在创建html代码，一些
生成的html代码存储在字符串XSLTOutput.ToString()中，该字符串稍后作为文字控件插入ASP页面。背后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，并允许它插入html控件
如果你想使用<控件，我猜你试图使用XDocOffers作为数据源。如果没有，你必须自己编写代码从数据库中查询。
您可以运行代码并查看XDocOffers XML文档及其结构。然后你可以明确询问哪个成员你想要用作下拉键，哪个作为下拉值。具体来讲下拉控件
