Hello Raj,   1-In the code behind assign the datasource to gridviews protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { List lists1 = new List(); lists1.Add(1); lists1.Add(12345); lists1.Add(234354); lists1.Add(3421); lists1.Add(2343); g1.DataSource = lists1; g1.DataBind(); List lists2 = new List (); lists2.Add(1); lists2.Add(1234567); lists2.Add(234354); lists2.Add(334421); lists2.Add(2343343); g2.DataSource = lists2; g2.DataBind(); } } 2-On the compare button click do the comparison. protected void btn_Click(object sender, EventArgs e) { List newLists = new List(); //iterate first gridview foreach (GridViewRow row1 in g1.Rows) { if (row1.RowType == DataControlRowType.DataRow) { string gv1Value = row1.Cells[0].Text; //iterate second gridview foreach (GridViewRow row2 in g2.Rows) { if (row2.RowType == DataControlRowType.DataRow) { string gv2Value = row2.Cells[0].Text; //do comparison here if (gv1Value.Contains(gv2Value)) { //if your criteria are met, put the data in the new lists newLists.Add(Convert.ToInt32(gv1Value)); } } } } } if (newLists.Count > 0) { g3.DataSource = newLists; g3.DataBind(); } }     May be this is helpful for you. Kindly accept the answer.
