Question

J'ai un frmEdit avec datagridview qui est bouned à ceci:

string sqlqry1 = "select p_Name from Items where p_Id=" + p_Id; 
     using (SqlCeDataAdapter a = new SqlCeDataAdapter(sqlqry1, conn)) 
     { 
      DataTable dt1 = new DataTable(); 
      a.Fill(dt1); 
      dataGridView1.DataSource = dt1; 
     } 

Comment modifier les cellules et les enregistrer à la db ?, ce essayé d'utiliser:

using (SqlCeDataAdapter a = new SqlCeDataAdapter(sqlqry1, conn)) 
     { 
      DataTable dt1 = new DataTable(); 
      a.Fill(dt1); 
      dataGridView1.DataSource = dt1; 
      a.Update(dt1); 
     }

     da = new SqlCeDataAdapter("select * from Items", conn); 
     cmdBuilder = new SqlCeCommandBuilder(da); 
     da.Fill(myDatabaseDataSet, "Items"); 
     myDatabaseDataSet.Tables["Items"].Rows[0]["p_Name"] = dataGridView1.Rows[0].Cells["p_Name"].Value.ToString();

DataTable dT; 
BindingSource bS; 

using (SqlCeConnection yourConnection = new SqlCeConnection("Data Source=|DataDirectory|\\YourDatabase.sdf")) 
{ 
    dT = new DataTable(); 
    bS = new BindingSource();  

    string query = "SELECT * FROM table01"; 
    SqlCeDataAdapter dA = new SqlCeDataAdapter(query, yourConnection); 
    SqlCeCommandBuilder cBuilder = new SqlCeCommandBuilder(dA); 
    dA.Fill(dT); 

    bS.DataSource = dT; 
    dgv01.DataSource = bS; 
}
