You can put the dynamically generated ID in your divID.innerHTML as I mentioned above.

And if you would like to print a specific div on your page, That can be done by using javascript window.print() method.

However, if you want to call javascript from your code behind, then, you would need to use ScriptManager.RegisterStartupScript() method. There are other methods as well in ScriptManager.

"<html><head><title></title></head><body>" +
divElements + "</body>";

//Print Page
window.print();

//Restore orignal HTML

Good to see that the articles supplied have helped you - as I could see you have used printDiv function and ScriptManager functions from the supplied pointers.

Please mark the threads which helped you as answer, so that it will be useful for the others while searching for the same issue and they can then go through the related articles to understand the concept fully..

You can create the div dynamically by using HtmlGenericControl.
Reference: http://msdn.microsoft.com/en-us/library/5f8y80ez%28VS.80%29.aspx

void Page_Load(Object sender, EventArgs e)
  {
    // Create a new HtmlGenericControl.
    HtmlGenericControl NewControl = new HtmlGenericControl("div");

    // Set the properties of the new HtmlGenericControl control.
    NewControl.ID = "NewControl";
    NewControl.InnerHtml = "This is a dynamically created HTML server control.";

    // Add the new HtmlGenericControl to the Controls collection of the
    // PlaceHolder control.
    ControlContainer.Controls.Add(NewControl);
    // Here ControlContainer is the ID of the asp:PlaceHolder defined in the aspx page. Just for example.
  }

 <asp:PlaceHolder ID="ControlContainer"                        runat="server"/>

Yes, you can write your printdiv function in your .aspx code.

And you can call the printdiv function exactly in the same line, like how you are calling alert function.

Hope this clarifies.
