Answer 1

"MyTable".DefaultView.RowFilter = " LIKE '%" + textBox1.Text + "%'"; this.dataGridView1.DataSource = "MyTable".DefaultView;

I use this code to get the data out:

con = new System.Data.SqlServerCe.SqlCeConnection();
con.ConnectionString = "Data Source=C:\\Users\\mhadj\\Documents\\Visual Studio 2015\\Projects\\data_base_test_2\\Sample.sdf";
con.Open();

DataTable dt = new DataTable();

adapt = new System.Data.SqlServerCe.SqlCeDataAdapter("select * from tbl_Record", con);        
adapt.Fill(dt);        
dataGridView1.DataSource = dt;
con.Close();
