Think of the dataview as a window into a portion of the data. If you are a
looking at a picture of data you can look at it in certain ways and filter
it to bring out portions of the data of interest to you, but you can't touch
the data. Hope this picture helps you understand what is going on. For a
comprehensive book on the subject as well as other technologies related to
the data layer, see David Sceppa's book, programming Ado.Net.

Hello .net expert, I've made a litle reserch function which allow the user
to find a client by name
or phone number (both are string format) .

Even if I know the value exist, the datagrid return me nothing.
Any Idea what would be the problem ??
Thanks in advance !!

Hi Esperanza,

How do you fill whole data to the dataview?
