    <p>Basically I have a c# application which takes values from a textfile, stores them in lists and transfers them into SQLite tables. </p> <p>The three tables are named abc, t2, and t3 respectively.</p> <p>I want to then take those sqlite tables and present them in the c# app in datagridviews. So far I've been been able to transfer 1 table (table abc) to the grid view. <strong>I want to transfer all 3 tables to the gridview.</strong></p> <p><strong>Problem:</strong> I want to make the 3 tables appear in ONE grid but I simply don't know the syntax on how to do accomplish that.</p> <p>The following is just how the 3 tables are populated. The more important code (transferring data to grid) is below this</p> <pre><code> // TRANSFERING VALUES TO THE SQLITE DB private void button4_Click(object sender, EventArgs e) { // We use these three SQLite objects: SQLiteConnection sqlite_conn; SQLiteCommand sqlite_cmd; SQLiteDataReader sqlite_datareader; // create a new database connection: // Maybe error here - video was different sqlite_conn = new SQLiteConnection(@"Data Source=database.db;Version=3;"); // open the connection: sqlite_conn.Open(); // create a new SQL command: sqlite_cmd = sqlite_conn.CreateCommand(); // Let the SQLiteCommand object know our SQL-Query: sqlite_cmd.CommandText = "CREATE TABLE IF NOT EXISTS 'abc' (Seq text, Field text, Desc text, Len text, Dec text, Typ text, Percnt text, Pop text, Alzero text, MaxLen text );"; // Now lets execute the SQL sqlite_cmd.ExecuteNonQuery(); // **** SQLITE TRANSFER SECTION 1 - transfer values from list1 to table1 ***** sqlite_cmd.CommandText = " DELETE FROM abc"; sqlite_cmd.ExecuteNonQuery(); sqlite_cmd.CommandText = "INSERT INTO abc (Seq, Field, Desc, Len, Dec, Typ, Percnt, Pop, Alzero, MaxLen) VALUES (@p1, @p2, @p3, @p4, @p5, @p6, @p7, @p8, @p9, @p10)"; sqlite_cmd.Parameters.AddWithValue("@p1", 6);

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
