Answer : saving gridView selected reords in DataSet

as I said in my previous post if you have a dataset as the datasource of the GridView control and need to move that to a different dataset then just do this
DataSet FilteredDataSet=((DataSet)GridView1.DataSource); //This is assuming your GridView is called GridView1
after this code is executed FilteredDataSet will hold whatever data is held in the GridView control
