Please explain: what do you mean by "opening a Web form"? Was it close?
What does it mean, "multiple Web forms", multiple on the same page, or anything else?
How is that related to the fragment of code you show?

I have an search engine for school after that checkbox get checked by user and click on compare button. after that i want to open information on different window which the checkbox are checked.

Do you know the purpose of a "Web form"? Only to send HTTP request. "Open information" has nothing to do with a form. Okay, what is "open information"?
Anyway, you still did not answer my question.

Wouldn't it be better to open ONE page with values neatly arranged in the table for comparison?

But requirement is to open whole information in different pop ups. If u can help me so please do.

Let the one who gave you this "requirement" talk to us. Or please motivate the decisions rationally, without referring to "requirements". Why should we talk with someone who don't make relevant decisions?

Open Information means i want to show information of different different ids which are fetched by checkboxes and show in different different pop ups. Can you help me?

Above code opens only one pop up for one id and rest are neglected.

I have done by Myself. this is a demo code.

C#

protected void btnPop_Click(object sender, EventArgs e)
    {
        int i=1;
        string url = "" ;
        string name = "";
        if (i == 1)
        {
           url = "Login.aspx";
           i++;
           name = "my" + i;
           Response.Write("<script>window.open('" + url + "','"+name+"','width=400,height=400,left=300,top=150')</script>");
        }
        if (i == 2)
        {
            url = "Registration.aspx";
            i++;
            name = "my" + i;
            Response.Write("<script>window.open('" + url + "','" + name + "','width=400,height=400,left=300,top=150')</script>");
        }
