问题描述
我如何动态地添加ASP.NET页面加载用户控件?
我有 ID =contentData内容
和几个控件的div
- one.ascx
- two.ascx
- three.ascx
现在我已经创建了一个页面 Default.aspx的
,这可能会在查询字符串参数,通过以下方式之一:
的Default.aspx?VAL =一个
Default.aspx的?VAL =两个
Default.aspx的?VAL =三个
我从
取值 的Request.QueryString [VAL]
现在我怎么加载在这个特定的控制?
< DIV ID =controlData>< / DIV>
在你的aspx
< DIV ID =DIV1=服务器>< / DIV>
在Page_Load中
用户控件UC =(用户控件)Page.LoadControl(test.ascx);
div1.Controls.Add(UC);

How do I add a user control on page load dynamically in ASP.NET?
I have a div with ID="contentData"
and few controls
- one.ascx
- two.ascx
- three.ascx
Now I have created a page default.aspx
, which may get parameters in query string, in one of the following ways:
default.aspx?val=one
default.aspx?val=two
default.aspx?val=three
I am taking the value from
Request.QueryString["val"]
Now how do I load specific control in this?
<div ID="controlData"></div>
In your aspx
<div id="div1" runat="server">
</div>
In Page_Load
UserControl uc = (UserControl)Page.LoadControl("test.ascx");
div1.Controls.Add(uc);
All you need to do is make your div server bound by adding runat="server", and in the codebehind use Page.LoadControl to go out and fetch your usercontrol and then add it to your div using the div's Controls.Add
