Referencing to usercontrol from another aspx-file

Question

User1024180000 posted

I have an application which is structured like this:

Page1.aspx

    UserControl1

    UserControl2

Page2.aspx

    UserControl1

    UserControl2

Both pages are using same Master Page. However I'm unable to access User Control1 in Page1.aspx from UserControl1 in Page2.aspx. In Page2.aspx.cs I have tried this:

          ContentPlaceHolder mpContentPlaceHolder = (ContentPlaceHolder)(Page.Master.FindControl("myContentPlaceHolder"));
          Page1UserControl userCtrl = (Page1UserControl)(mpContentPlaceHolder.FindControl("controlName"));
         

I have already declared properties in User Controls so if I wanted to access MyProperty (Page1.aspx, UserControl1) value from User Control1 (Page2.aspx) I would like to do it like this:

      userCtrl.MyProperty = "123";

I get an error message and userCtrl has a value of null. Actually userCtrl points to Page2.aspx instead of Page1.aspx. How can I change this ?

By default controls access modifiers are protected. You can make it public to access outside

 I don't think it works that way.  Each page is independent, and only objects on the displaying page exists at the moment. It's not like a windows application where several pages can exist at the same time, and you can access those pages objects. It's a web program, not a windows program!.

You can place both pages on the same page, and separate them with div tags, or panels, and toggle visibility.
