after some testing I came with this way to handle my datagrid. dgVariedad_CellEditEnding use the function nombreVariedadDisponible(txtBoxTemporal.Text) to check if the new value already exist in List<Variedad> variedades and it works. The problem is that the value wont be inserted in the database but will be added in the datagrid control, I can't find a way to cancel the new row in the control.
private List<Variedad> variedades = new List<Variedad>();
private void bindVariedad()
{
using (MySqlCommand cmd = Conexion.con.CreateCommand())
{
cmd.CommandText = "SELECT NOMBRE FROM DATAFRUT_VARIEDADES WHERE ELIMINADO = 'F';";
Conexion.abrirConexion();
MySqlDataAdapter da = new MySqlDataAdapter(cmd);
DataTable table = new DataTable("DATAFRUT_VARIEDADES");
da.Fill(table);
table.Columns[0].ColumnName = "Nombre";
dgVariedad.ItemsSource = table.DefaultView;
cmd.CommandText = "SELECT * FROM DATAFRUT_VARIEDADES WHERE ELIMINADO = 'F';";
using (MySqlDataReader dr = cmd.ExecuteReader())
{
variedades.Clear();
while (dr.Read())
{
Variedad var = new Variedad();
var.codigo = Convert.ToInt32(dr[0]);
var.nombre = dr[1].ToString();
var.eliminado = Convert.ToChar(dr[2]);
variedades.Add(var);
}
}
}
}
private void dgVariedad_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
{
TextBox txtBoxTemporal = e.EditingElement as TextBox;
int indice = e.Row.GetIndex();
if (e.Row.IsNewItem)
{
if (nombreVariedadDisponible(txtBoxTemporal.Text))
{
bool insertExitoso = false;
using (MySqlCommand cmd = Conexion.con.CreateCommand())
{
Conexion.abrirConexion();
cmd.CommandText = "INSERT INTO DATAFRUT_VARIEDADES VALUES (default, '" + txtBoxTemporal.Text + "', 'F');";
try
{
cmd.ExecuteNonQuery();
insertExitoso = true;
}
catch
{
MessageBox.Show("Error");
}
Conexion.cerrarConexion();
}
if (insertExitoso)
{
variedades.Add(Variedad.cargarUltimoInsert(txtBoxTemporal.Text));
}
}
else
{
e.Cancel = true;
}
}
else
{
using (MySqlCommand cmd = Conexion.con.CreateCommand())
{
Conexion.abrirConexion();
DataRowView dataRow = (DataRowView)dgVariedad.SelectedItem;
cmd.CommandText = "UPDATE DATAFRUT_VARIEDADES SET NOMBRE = '" + txtBoxTemporal.Text + "' WHERE CODIGO = " + variedades[dgVariedad.SelectedIndex].codigo + ";";
try

My table on mysql has 3 fields:
int codigo (primary key, auto increment)
string Nombre (Unique) char
char Eliminado -> Eliminado (Deleted) with values (F = false and V =
true)
Here is how I check if the value already exist.
private bool nombreVariedadDisponible(string nombreAComparar)
{
//busca el nombre en la lista "variedades"
foreach (Variedad var in variedades)
{
if (var.nombre.ToLower() == nombreAComparar.ToLower() && var.eliminado == 'F')
return false;
}
return true;
}

enter image description hereI tried to update selected columns of SQL Database table which from DataGridView. But it said my input string is wrong.So how to fix this.(PO_No is the primary key of PO table and it has identity value and also it is the foreign key of PO_Cart table)
public void UpdatePOCartTable(int PO_No,string ISBN_No,int OrderQuantity, decimal UnitPrice, decimal Total)
{
DynamicConnection con = new DynamicConnection();
con.mysqlconnection();
string query = "UPDATE TBL_PO_Cart"

+ "UnitPrice= #UnitPrice, Total=#Total"
+ "WHERE PO_No = #PO_No";
con.sqlquery(query);
con.cmd.Parameters.Add(new SqlParameter("#PO_No", SqlDbType.Int));
con.cmd.Parameters["#PO_No"].Value = PO_No;
con.cmd.Parameters.Add(new SqlParameter("#ISBN_No", SqlDbType.NVarChar));

con.cmd.Parameters.Add(new SqlParameter("#OrderQuantity", SqlDbType.NVarChar));
con.cmd.Parameters["#OrderQuantity"].Value = OrderQuantity;
con.cmd.Parameters.Add(new SqlParameter("#UnitPrice", SqlDbType.Money));
con.cmd.Parameters["#UnitPrice"].Value = UnitPrice;
con.cmd.Parameters.Add(new SqlParameter("#Total", SqlDbType.Money));
con.cmd.Parameters["#Total"].Value = Total;
con.nonquery();
}
private void btnedit_Click(object sender, EventArgs e)
{

try
{
if (txtPONo.Text != "" || cmbsupID.Text != "" || date1.Text != "" || requireddate.Text != "" || txtgrandTotal.Text != "")

for (int i = 0; i < dataGridView1.Rows.Count-1; i++)
{

When Updating SQL I normally use the following code:
String CommandLine = "UPDATE CA_temp_data SET TimePast=#selectTot WHERE TicketNumber=#id";
using (SqlConnection Conn = new SqlConnection("Data Source=" + hostString + ";User ID=" + usernamestring + ";Password=" + sqlpassword))
{
try
{
SqlCommand cmd = new SqlCommand(CommandLine, Conn);
cmd.Parameters.AddWithValue("#id", ticket);
cmd.Parameters.AddWithValue("#selectTot", time);
using (Conn)
{
Conn.Open();
cmd.ExecuteNonQuery();
Conn.Close();
}
}
catch (System.Exception excep)
{
}
Can somebody help understand this code?
protected void Page_Load(object sender, EventArgs e)
{
Database database = new Database();
OleDbConnection conn = database.connectDatabase();
if (Request.Cookies["BesteldeArtikelen"] == null)
{
lbl_leeg.Text = "Er zijn nog geen bestelde artikelen";
}
else
{
HttpCookie best = Request.Cookies["BesteldeArtikelen"];
int aantal_bestel = best.Values.AllKeys.Length;
int[] bestelde = new int[aantal_bestel];
int index = 0;
foreach (string art_id in best.Values.AllKeys)
{
int aantalbesteld = int.Parse(aantalVoorArtikel(int.Parse(art_id)));
int artikel_id = int.Parse(art_id); // moet getalletje zijn
if (aantalbesteld != 0)
{
bestelde[index] = artikel_id;
}
index++;
}
OleDbCommand cmd = new OleDbCommand();
cmd.Connection = conn;
cmd.CommandText = "SELECT artikel_id, naam, prijs, vegetarische FROM artikel WHERE artikel_id IN (" +
String.Join(", ", bestelde) + ")";
try
{
conn.Open();
OleDbDataReader reader = cmd.ExecuteReader();
GridView1.DataSource = reader;
GridView1.DataBind();
}
catch (Exception error)
{
errorMessage.Text = error.ToString();
}
finally
{
conn.Close();
}
}
}
And there is this part of code i dont really understand:
public string aantalVoorArtikel(object id)
{
int artikel_id = (int)id;
if (Request.Cookies["BesteldeArtikelen"] != null &&
Request.Cookies["BesteldeArtikelen"][artikel_id.ToString()] != null)
{
return Request.Cookies["BesteldeArtikelen"][artikel_id.ToString()];
}
else
{
return "0";
}
}
It extracts values from a cookie and builds an int array. (Displays a message if the cookie value is null) The int array is then used as the value for the SQL IN operator when querying the database. The result set is then bound to the GridView.
I looked for a solution to this problem on the forum, but I didn't find one for my problem. On button click, I receive error:
There is already an open DataReader associated with this Connection which must be closed first.
So, I tried to close all DataReaders after using them, I tried to use CommandBehavior, but none of them worked. I tried to use using(MysqlCommand...) but didn't work. What can I do? The strangest thing is that the code is working, but after each button press, I receive that error again. Any ideas?
Please don't flag question as a duplicate, I know that the question exist here but the answer is missing for my problem I guess.

let all the other codes as it is
The root cause of your exception is that you are executing other queries while you are still iterating over the results of an earlier query.
Bottom line you should not nest queries like you do if you use the same connection for the nested queries.
You are using reader to fetch data from SQLCommand upd.
Then you are reading value.
After that you are using another SqlCommand 'update' to update the result..
Even when you use two different SQLCommands, you are using the same connection. Thats the problem. Use a sperate connection for the second SQLCommand and your problem will be solved.
Try this.
after the line
MessageBox.Show("Timpul a expirat. Ai picat!");
add like
MessageBox.Show("Timpul a expirat. Ai picat!");
MySqlConnection conn1 = ConnConfig.getConnection();
MySqlConnection conn2 = new MySqlConnection();
conn2.ConnectionString = conn1.ConnectionString;
conn2.Open();
and then in the line
MySqlCommand upd = new MySqlCommand("select totalno from accounts where username = '" + Index.textBox1.Text + "'", ConnConfig.getConnection());
change like
MySqlCommand upd = new MySqlCommand("select totalno from accounts where username = '" + Index.textBox1.Text + "'", conn1);
and in line
using (MySqlCommand update = new MySqlCommand("UPDATE accounts SET totalno=#totalnu where username = '" + Index.textBox1.Text + "'", ConnConfig.getConnection()))
change like
using (MySqlCommand update = new MySqlCommand("UPDATE accounts SET totalno=#totalnu where username = '" + Index.textBox1.Text + "'", conn2))
This is how it works. I select a row from my listview then I will click "Edit" button which the values from the selected item will also be shown in the registration form. The "Register" button will now then changed to "Update". I am trying to update my customers table after changing inputs from the textboxes on my registration form but there are no changes in my database.
I receive no errors but I might have missed something here.

First, I think you should use ExecuteNonQuery() instead of ExecuteReader().
You call ExecuteReader() when you execute a sql command that returns something (such as SELECT).
When you call a command that doesn't return anything (such as INSERT, UPDATE, DELETE, etc.), you should call ExecuteNonQuery().
See the details here.
Second, I think you should check the result before alert "successfully". ExecuteNonQuery() returns the number of rows affected, you can check this to determine success or not.
I have no idea what to do anymore with this code. I did review the opening and closing of my connections and I think all connections are okay.
I have to tables here that I'm trying to insert data. The imf table and the imf_products table. My goal is as soon as I have inserted data to my imf table I should insert data again to my imf_products.
