not what is actual error are you facing here/. can you eloborate more. but normally for sql connection you need to have datasoruce and then you can use below code to execute any query. using (SqlConnection conn = new SqlConnection()) { conn.ConnectionString = "your data source string" conn.Open(); SqlCommand insertCommand = new SqlCommand( "INSERT INTO Mytable (Id, name) VALUES (@0, @1)" , conn); insertCommand.Parameters.Add( new SqlParameter( "0" , txtbox1.value)); insertCommand.Parameters.Add( new SqlParameter( "1" , txtbox2.value)); insertCommand.ExecuteNonQuery(); }

You have to use sql parameters to hold the values from your TextBox or any other controls. For example: private void InsertRecord( int ID , string name){ string dbConnectionString = ConfigurationManager.ConnectionStrings[ "MyDBConnectionString" ].ConnectionString; using (SqlConnection connection = new SqlConnection(dbConnectionString)) { string sql = "INSERT INTO MyTable(ID, Name) VALUES (@ID, @Name" ; using (SqlCommand cmd = new SqlCommand(sql, connection)) { connection.Open(); cmd.Parameters.AddWithValue( "@ID" , ID); cmd.Parameters.AddWithValue( "@Name" , name); cmd.ExecuteNonQuery(); } } } protected void addB_Click( object sender, EventArgs e){ InsertRecord(Convert.ToInt32(TextBox1.Text), TextBox2.Text); } If you are new to ADO.NET, you should read this article: https://docs.microsoft.com/en-us/dotnet/framework/data/adonet/ado-net-code-examples

private void Insert (int ID , string name){ using (SqlConnection con = new SqlConnection(Your data source ConnectionString)) { string query = "Insert into table values (@ID, @Name)"; SqlCommand cmd = new SqlCommand(query, con); cmd.CommandType = CommandType.Text; con.Open(); cmd.Parameters.AddWithValue(@ID, ID); cmd.Parameters.AddWithValue(@Name,Name); cmd.ExecuteNonQuery(); } }
