Hi, Suppose this is sample code : DataClasses1DataContext db = new DataClasses1DataContext(); IQueryable catalogNo = db.Product_Details.Select(p => p.pcatalog); Then You can use .Any() if(catalogNo.Any()) { //I have Data!!! } else { //No data found }

public DataView GetProductByID ( string name ) { using ( SqlConnection conn = new SqlConnection ( connstring )) { //string products = @ "select*from TblName where name ='" + name + "'" ; //SqlDataAdapter da = new SqlDataAdapter ( products , conn ); // DataSet ds = new DataSet (); conn . Open (); // da . Fill ( ds ); return ds . Tables [ 0 ]. DefaultView ; //------------ if LINQ otherwise comment this and use above----------------------// var products= from TblName in customers where cust.City == '" + name + "'" ; select cust; foreach (string s in products){ if (s!=""){//show what do you want} else { Label1.ForeGround = System.Colors.Color.Red; Label1.Text = "No Record found!" ; } } //------------------- end LINQ------------// } } DataView dvproduct = new DataView (); dvproduct = objManageStore . GetProductByID ( Name ); if ( dvproduct . Table . Rows .

List tblList = (from tb1 in dbEntities.Table1 where tb1.id == 1 // Based on your search criteria select tb1).ToList(); if(tblList == null || tblList.Count() == 0) { label1.foreGround = System.Colors.Color.Red; label1.text = "No Record found!" ; }
