关于动态加载用户控件问题

Question

动态加载用户控件Control c1=Page.LoadControl("inc/productEditAdd.ascx");productEditAdd.ascx文件内容：
protected string editOrAdd;
public string EditOrAdd
{
get
{
return editOrAdd;
}
set
{
editOrAdd=value;
}
}请问一下如何设置editOrAdd的值，c1.EditOrAdd好像没有？

Answer 1

Control c1=Page.LoadControl("inc/productEditAdd.ascx");
错了，应该是
productEditAdd c1 = Page.LoadControl("inc/productEditAdd.ascx") as productEditAdd;

Answer 2

productEditAdd c1 = Page.LoadControl("inc/productEditAdd.ascx") as productEditAdd;
c1.EditOrAdd = "xxxx";
...

Answer 3

Control c1=Page.LoadControl("inc/productEditAdd.ascx");
改为：
productEditAdd c1=(productEditAdd)LoadControl("inc/productEditAdd.ascx");
c1.EditOrAdd="XXX";

Answer 4

这个方法是行，只是我的程序是这样的，用这种方法要多写些代码。 Control c1=new Control();
if(Session["adminName"]==null||Request.QueryString["a"]==null)
{
c1=Page.LoadControl("inc/adminMain.ascx");
this.mainPanel.Controls.Add(c1);
}
else
{
switch(Request.QueryString["a"].ToString())
{
case "1":
c1=Page.LoadControl("inc/productSortEdit.ascx");
break;
case "2":
switch(Request.QueryString["b"].ToString())
{
case "1":
c1=Page.LoadControl("inc/productEdit.ascx");
break;
case "2":
c1=Page.LoadControl("inc/productEditAdd.ascx");
break;
}
break;
case "3":
c1=Page.LoadControl("inc/adminPwd.ascx");
break;
}
this.mainPanel.Controls.Add(c1);

c1=Page.LoadControl("inc/adminMain.ascx");
this.mainPanel.Controls.Add(c1);
}
else
{
switch(Request.QueryString["a"].ToString())
{
case "1":
c1=Page.LoadControl("inc/productSortEdit.ascx");
break;
case "2":
switch(Request.QueryString["b"].ToString())
{
case "1":
c1=Page.LoadControl("inc/productEdit.ascx");
break;
case "2":
c1=Page.LoadControl("inc/productEditAdd.ascx");
break;
}
break;
case "3":

}
this.mainPanel.Controls.Add(c1);
