Advice on Dynamic Controls

    I am in need of some advice on how to do the following:

    Have some type of container on form that would fill the visible area on
    screen (assuming the browser was maximized). I would like to specify a
    number of vertical columns that would be equally spaced. I would then like
    to be able to dynamically add a variable number of various types of web
    controls in a top to bottom fashion. When the maximum number of controls
    placed in a column would not be visible on the screen, additional controls
    would 'flow' to the next column and so on. I was able to achieve only
    limited success with this using a Table control. The problem was knowing
    when I had reached the maximum number of controls that would be visible,
    without scrolling, on the screen and starting in the next column.

    Thank you for your help.

    Thank you for reply and sample. You've once again analyzed my question
    correctly. I work with your suggestions and the attachment today and let
    you know.

    I haven't heard from you. Have you had a chance to fully test on my former
    suggestions or have you got any progress on this issue? If you have any
