Hi! I need to retrieve a variable from the querystring and based on that variable, show or not show some user controls. So I've already come this far:

<% switch(Request.Querystring("mid")
      {
           case "0":
                         break;
             case "1":
                         break;
           case "2":
                         break;
           default:
                         break;
        }
%>

Which ofcourse, doesn't do a thing. Even though this is C#, you should get the idea. Now, how can I create a different UserControl for each case?<% switch Request.Querystring("mid") { case 0: break; case 1: break; case 2: break; default: break; } %><% switch Request.Querystring("mid") { case 0: break; case 1: break; case 2: break; default: break; } %><% switch Request.Querystring("mid") { case 0: break; case 1: break; case 2: break; default: break; } %><% switch Request.Querystring("mid") { case 0: break; case 1: break; case 2: break; default: break; } %><% switch Request.Querystring("mid") { case 0: break; case 1: break; case 2: break; default: break; } %>

Put a placeholder onto you page and then do


Dim myControl as Control

Case 0

 myControl = me.LoadControl("control0.ascx")

 Placeholder1.Controls.Add(myControl)

Case 1

 ....

Should give you an idea

I think he wants to dynamically hide controls not load them, in which case use:



<% switch(Request.Querystring("mid")
      {
              case "0":

                userControl1.Visibile = true;
 
         &nbs p;   
         &nbs p;
   break;
              case "1":

                userControl2.Visibile = true;

 
         &nbs p;   
         &nbs p;
   break;
              case "2":

                userControl3.Visibile = true;

 
         &nbs p;   
         &nbs p;
   break;
              default:

                defaulUserControl.Visible = true;
 
         &nbs p;   
         &nbs p;
   break;
        }
%>

And just set the visibility of all the controls to false in the designer
