DataSet ds = <-- Get data from Webservice here
DataTable dt = ds.Tables[0];
DataView view = new DataView(dt);
DataTable resultTable = view.ToTable(false, "Column1", "Column2","Column3","Column4","Column5","Column6");
dataGridView1.DataSource = resultTable ;
I am assuming you are getting data into dataset ds.
Dataset actually contains tables.
you just have take the data in datatable from data set.
I Hope it will work for you.
