我有一个Listview，它包含名为description的字段（可能很长） 现在我想设置更多阅读，当用户点击阅读更多时，它应该在弹出窗口中给出完整的描述。
代码设计：
<asp:ListView ID="listcourse" runat="server" >
<ItemTemplate>
<p >
<div>
<b>
<%# (Eval("Description").ToString().Length <=150)?Eval("Description").ToString(): Eval("Description").ToString().Substring(0, 150) + "...Readmore"%>
</b>
</div>
</p>
</ItemTemplate>
</asp:ListView>
C＃代码：
public void bindList()
{
listcourse.DataSource = DB.Tbl_Categories_Master.Where(p => p.Deleted == true && p.Parent_Cat_id == 0);
listcourse.DataBind();
}
我该怎么办？

由于它的MVC应用程序，默认情况下模板使用Bootstrap，我给你这个解决方案。
在<script>标记中添加此内容。
$(function(){
$('div.popOverWrapper b').popover()
});
同时修改您的HTMl div标签，使其成为名为popOverWrapper
<asp:ListView ID="listcourse" runat="server" >
<ItemTemplate>
<p>
<div class="popOverWrapper">
<b>
//....
</b>
</div>
</p>
</ItemTemplate>
</asp:ListView>
所以从技术上来说，我正在做的是首先使用我选择的类名标记我的各自的div。稍后当文档准备就绪时，我会找到这个div并在其中找到b标签并应用引导程序 .popover() 插件

You can achieve this using Web service - Try this, It may help you.
---Web service code---
[WebMethod]
public string getFullDescription(int ID) {
string result = "";
using (SqlConnection con = new SqlConnection(@"Data Source=SANTOSH-PC\SQLEXPRESS;Initial Catalog=master;User ID=sa;Password=ssrana@317"))
{
SqlCommand com = new SqlCommand("select description from discriptionList where id="+ID+"", con);
con.Open();
SqlDataReader rdr = com.ExecuteReader();
if (rdr.Read())
{
result = Convert.ToString(rdr["description"]);
}
}
return result;
}
---.Aspx code---
<div>
<asp:ListView ID="lstView" runat="server" DataKeyNames="id" GroupItemCount="4" OnItemDataBound="lstView_ItemDataBound">
