asp c# sql

My problem is that I have all kinds of different tables that I would like to have the same form data entry for. The table structures are subject to change at a moments notice and for flexibility I want to keep it that way.
Here's essentially what I have so far:

code_infront
<asp:placeholder id="phUserForm" runat="server"></placeholder>

code_behind
sqldatareader for sql to get columns : exec getColumns for id=Apples1234567 (gets entry from tblColumnKey).
--- How to? Generate code_infront form elements based on the data returned.
--- How to? Accept values from said forms"
SQL Layout:
tblColumnKey
ColumnName | ColumnType | FieldOrder
-------------------------------------
Name       | varchar(80) | 1
Photo      | blob        | 2
BirthDay   | datetime    | 3

etc...

code:

tblApples1234567
Name     |   Photo | BirthDay
-------------------------------------

It's called "using a brain".
