For SQLCE you need to use the SqlCeXXX classes:

C#

SqlCeConnection con = new SqlCeConnection(ConStr);

private void addBtn_Click(object sender, EventArgs e) 
{ 
   string InsStr = "insert into student values '"+textBox1.Text+"','"+textBox2.Text+"')"; 
   SqlCeDataAdapter da = new SqlCeDataAdapter (InsStr, con); 
   DataTable dt = new DataTable("student"); 
   da.Fill(dt); 
   MessageBox.Show("Record inserted succesfully..."); 
}

Also you must Open() the connection before using it.

Don't use an ODBC connection, use an SqlCeConnection instead:

C#

using (SqlCeConnection con = new SqlCeConnection(ConnectionString))
    {
    con.Open();
    using (SqlCeCommand cmd = new SqlCeCommand("SELECT iD, userName FROM MyTable", con))
        {
        SqlCeDataAdapter da = new SqlCeDataAdapter(cmd);
        da.Fill(dt);
        }
    }

You may need to download it first (http://www.microsoft.com/en-us/download/details.aspx?id=5783[^]) and add a reference to "System.Data.SqlCE.dll"
