DataView changing with the table.

[George]

I have a small problem with DataView.

my DataTable has a field "selected" i am setting that field value to "1" and then getting DataView dv1 by filtering on "selected=1"
Then i am resetting selected back to 0 and setting it to "1" for another set of rows. Then i am getting DataView dv2.

My problem is that dv1 and dv2 turned out to have the same rows.

Looks like DataView detects my data manipulations and excludes/includes records according to the filter.

How can i prevent that. Can i disable monitoring and have it to behave like a static snapshot.

Thanks
George.
