    Passing variables to another form

    Im working in ASP.net with C#, and I want to pass hidden form variables from one page when I click a link, to another page. My problem is I dont know how to do that. I was thinking about using Reqest.Form or something, but I cant figure out how that would work.

    Why not put them in the session or cache?

    Anyways the proper way to do this is to create a reference.

    In the old page add

    Code:
    <%@Page ClassName="SenderPage" %>
    in the script add something like this (property)
    Code:
    public string SomeVar{
                       get{return TextBox1.Text;}
    }
    now in recipient form

    Code:
    <%@Reference Page="SenderPage.aspx" %>
    Code:
    SenderPage sp;
    
    void page_load(object sender, EventArgs e){
                     sp = (SenderPage) Context.Handler;
    }
    This should do the job. But you can always use session variables.

    This always worked for me. You can pass objects to other forms this way, too. This example uses a simple string.

    Form 1:
    Code:
    MyForm mf = new MyForm(ref name);
    mf.Show();
    this.Hide();
    Form 2:
    Code:
    // in constructor
    public MyForm(ref string name) {
       this.name = name;
    }
    Edit: Oops, I didn't read the extra details in the original post.

    This seems to be for Windows forms. ASP.net are webforms and i dont know if they support such a thing.
