myConnection = WebConfigurationManager.ConnectionStrings["onnectionString"].ConnectionString; connect = new SqlConnection(myConnection); command = new SqlCommand(); connect.Open(); command.Connection = connect; string komut = "SELECT * FROM table name WHERE authername='"+textbox1.Text+"'"; try { SqlCommand sqlCommand = new SqlCommand(); sqlCommand = connect.CreateCommand(); sqlCommand.CommandText = komut; SqlDataAdapter sda = new SqlDataAdapter(sqlCommand.CommandText, connect); SqlCommandBuilder scb = new SqlCommandBuilder(sda); //Create a DataTable to hold the query results. DataTable dTable = new DataTable(); //Fill the DataTable. sda.Fill(dTable); GridView1.DataSource = dTable; GridView1.DataBind(); } catch (SqlException) { //Console.WriteLine(e.StackTrace); } reader.Close(); connect.Close();

Use like operator from sql The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. SELECT column_name(s) FROM table_name WHERE column_name LIKE pattern ex:SELECT * FROM Persons WHERE City LIKE 's%' Source:http://www.w3schools.com/sql/sql_like.asp
