I use the reaportView tool and you have to connect it to your database. I made a screenshot that I would like to introduce it to you

There is something that escapes me ...

and I wish I could print all the recordings from there via another form
I have a faith done but with access and this faith I use SQlite but as I emphasize them I do not see the data SQlite in my data source.

string txtQuery = "insert into InfoCode (Code, DateCode, PriceCode) values ​​('" + lblDisplay.Text + "', '" + dateTimePicker1.Text + "', '" + txtAfficePrice.Text + "')";

SELECT * FROM MyTable WHERE StreetAddress = 'Baker's Wood'

SELECT * FROM MyTable WHERE StreetAddress = 'x';DROP TABLE MyTable;--'

SELECT * FROM MyTable WHERE StreetAddress = 'x';

DROP TABLE MyTable;

--'

dataGridView1.DataSource = DT;

private void ExecuteQuery (String txtQuery)
{
        SetConnection ();
sql_con.Open ();
sql_cmd = sql_con.CreateCommand ();
sql_cmd.CommandText = txtQuery;
sql_cmd.ExecuteNonQuery ();

Thank you for all these tips for me will be a pulse to my learning. it's in my research that I found but what do you recommend to me?
I correct this error before talking about printing or after?

Frankly thank you for giving me your time. give me a few minutes just the time for me to redo my connection and I come back to you.
