Datagrid help

I know this is probaly really easy but i am having problems using a datagrid so i can put my data in my already built web page, i have a web page already built and i want to put the data in a certain part of the web page, but i can't figure it out and the data always keeps showing up in the top left corner, i am new to ASP.NET so any help is greatly appreciated, do i even use a datagrid, any ideas? Thanks!
