Using Arrays to Display Content RRS feed

  • Question

  • Hi,

    I am using below code to populate item modifiers into an array. The modifier_group_id could be any number from the table but it is unique as it is a primary key, e.g.:

    • 2
    • 17
    • 99
    • 107
    • 214

    I want once the load_item_modifiers is finished to run a code like this:

    private void display_modifiers(int mod_id) {

    next_mod_id = xxxx;

    // Show mod_control with details for mod_id = xxx

    // Next button when clicked will run disaply_modifiers(next_mod_id); }

    mod_control will have a Next button to display the next modifiers..

    How can I pass the next modifier every time to the display the mod for the current as above?

    so when the load_item_modifiers finish in the above example, it will show content for mod 2 and the next button in the content will run display_modifiers(17) ... when user clickes the button it will then display the contents for 17 and the next button will run display_content(99), etc..

    here is the array population code..

    private void load_item_modifiers(int item_id)
            sql_connection = new SqlConnection(serverClass.connectionstring("Savanna", "Savanna", "LocalServer"));
            sql_command = new SqlCommand("sp_load_item_modifiers", sql_connection);
            sql_command.CommandType = CommandType.StoredProcedure;
            // sql_command.Parameters.AddWithValue("@concept_id", 1).SqlDbType = SqlDbType.Int;
            sql_command.Parameters.AddWithValue("@item_id", item_id).SqlDbType = SqlDbType.Int;
            sql_reader = sql_command.ExecuteReader();
            List<int> modifiers = new List<int>();
            int i = 0;
            while (sql_reader.Read())
        catch (Exception exp)
            XtraMessageBox.Show(String.Format("Error Loading Modifiers.{0}{1}", Environment.NewLine, exp.Message), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
            if (sql_reader != null) { sql_reader.Close(); sql_reader.Dispose(); }
            if (sql_connection != null) { if (sql_connection.State == ConnectionState.Open) { sql_connection.Close(); sql_connection.Dispose(); } }

  • Hi Jassim,

    According to your title, you may use a loop as following,

    foreach(var item in yourArray)

    Also you may want to try something like this:

    yourArray.ToList().ForEach(i => Console.WriteLine(i.ToString()));

    How can I pass the next modifier every time to the display the mod for the current as above?

    Maybe for loop will be suitable for your scenario.

    // Loop over strings.
    	for (int i = 0; i < yourArray.Length; i++)
    	    string s = yourArray[i];
    	// Loop over strings backwards.
    	for (int i = yourArray.Length - 1; i >= 0; i--)
    	    string s = yourArray[i];

    Best regards,
