Question

我在自己的很少项目中装上了<代码>UserControl物体(file)。我随后在两个项目中提到了这个项目: 《教育、预算内方案部分、执行情况监测和评价方法条例和细则》(这是一个班级图书馆项目)和主要网站。

我确信,这在网站上很容易使用<代码>Controls。在任何<条码>中添加。网络控制将发挥作用。

然而,关于APIC的是什么? 我是否能够仅仅通过了解控制类型而使这种控制成为超文本吗? 。这种方法没有向作者写任何超文本,因为控制寿命周期甚至开始。

Please bare in mind that I don t have the controls in the web project, so I don t have a virtual path to the ascx file. So the LoadControl method won t work here.

All the controls actually derive from the same base control. Is there anything I can do from within this base class that will allow me to load the control from a completely new instance?

这是我最近所做的工作,但如果你在伙伴关系内使用,理解后退不会奏效。 NET app。

 [WebMethod]
 public static string GetMyUserControlHtml()
 {
     return  RenderUserControl("Com.YourNameSpace.UI", "YourControlName");
 }

 public static string RenderUserControl(string assembly,
             string controlName)
 {
        FormlessPage pageHolder = 
                new FormlessPage() { AppRelativeTemplateSourceDirectory = HttpRuntime.AppDomainAppVirtualPath }; //allow for "~/" paths to resolve

        dynamic control = null;

        //assembly = "Com.YourNameSpace.UI"; //example
        //controlName = "YourCustomControl"
        string fullyQaulifiedAssemblyPath = string.Format("{0}.{1},{0}", assembly, controlName);

        Type type = Type.GetType(fullyQaulifiedAssemblyPath);
        if (type != null)
        {
            control = pageHolder.LoadControl(type, null);
            control.Bla1 = "test"; //bypass compile time checks on property setters if needed
            control.Blas2 = true;

        }                          

        pageHolder.Controls.Add(control);
        StringWriter output = new StringWriter();
        HttpContext.Current.Server.Execute(pageHolder, output, false);
        return output.ToString();
 }


public class FormlessPage : Page
{
    public override void VerifyRenderingInServerForm(Control control)
    {
    }
}
