Possible: dynamically populated and placed user control in the middle of a string?

    I'm wondering if it's possible to do the following in ASP.NET 2.0. I want to
    do the following simultaneously. I suspect its possible, but I also suspect
    that I may need to do different things at different times in the page
    lifecyle, and would appreciate some guidance.

    a) call an ASP.NET user control in code (I know how to do this, subbing in
    for a ASP.NET placeholder control )

    b) interrogate my database for some information at runtime and dynamically
    populate the properties of the user control using the DB values
    (individually, I know how to do this too)

    c) "inject" the code that comprises the user control into the middle of
    another string I'm pulling out from the DB at runtime.

    The real-world application here is a content mangement scenario: imagine a
    user control that could hold a "mug shot" of a person and some related
    information, and you wanted this user control to appear midway through the
    body of a text article.

    Is this possible, or not?

    Thanks,

  2. Hi KF,

    I have also found your another thread "Subject: impossible or not:
    dynamically embedding a user control in the middle of a string?" describing
    the issue in the microsoft.public.dotnet.framework.aspnet newsgroup and I
    have posted my reply there.

    As I also mentioned there, if you want to insert a usercontrol at a random
    (not determined at design-time), I'm afraid the ASP.NET page/control model
    doesn't quite support this. Even dynamic created control need a fixed
    holder/container (placeholder) on the page. For your scenario, you may
    consider dynamically embed some html element in the text string( such as
    html <img> or <iframe> ) because such element does not require ASP.NET
    runtime parsing and compilation and can link to other resources via a given
    url.
