In your .aspx Page create a div with attribute as runat="server" and give an ID to it.
Then in the code behind you can use the InnerHtml property of the div tag to insert data into database
e.g
<div id="divDynamic" runat="server">
</div>
string sValueTobeShowninDiv ="";
divDynamic.InnerHTML=sValueTobeShowninDiv;
You can put data from DB in the string variable and show it in the div.
Hope This Helps!!!
