        private void txtsearchgroup_KeyUp(object sender, KeyEventArgs e) {
        SqlConnection objconnection = new SqlConnection(servername and ...);
        DataView Dv = new DataView();
        objcommand = new SqlCommand("select name from groupitems", objconnection);
        objdataadapter = new SqlDataAdapter();
        objdataadapter.SelectCommand = new SqlCommand();
        objdataadapter.SelectCommand = objcommand;
        objdataset = new DataSet();
        objconnection.Open();
        objdataadapter.Fill(objdataset);
        Dv.Table = objdataset.Tables[0];
        Dv.RowFilter = " name LIKE '%" + txtsearchgroup.Text + "%'";
        dataGridView1.DataSource = Dv;
        objconnection.Close(); }

• txtsearchgroup : name of textbox for search word in datagridview1 and
• txtsearchgroup_KeyUp : event of keyup for search and filter word in datagridview1 and
• select name from groupitems : name is field for groupitems table and
• Dv.Table = objdataset.Tables[0] : zero (0) is first table in dataset
