In a GridView i have a new dataset i want to show in it.
I dont know how to make the gridview show my new dataset.

Say, if i add my data to the gridview:
Me.grdGifts.DataSource = gifts
Me.grdGifts.DataBind()

this does not actually make the data updated in the gridview for me.
I have been thinking of an alternative and it is to remove the
gridview and then to create it all over again but i think it might make
the web page rather slow?

Thanks, Christian Otrel
