Fitting the solution of a differential equation to a data set

Hi list, given a set of data (e.g. {x,y} pairs) and a theoretical model described by a differential equation (with some free parameters) that cannot be solved analytically, I am searching for a way to somehow use Mathematica to fit the numerical solution of the equation to the data set. Unfortunately I failed to utilize FindFit and NDSolve on this behalf (which might very well be due to my lack of experience with Mathematica...). Any suggestions on how to do this? Kind regards, Timm
