How to insert multiple selected values in list box to different rows (one in each row) in database?

Hi shubhangi,

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Data.OleDb;
namespace Datagridview_bind
{
    public partial class Form1 : Form
    {
        string ConnectionString = System.Configuration.ConfigurationSettings.AppSettings["dsn"];
        OleDbCommand com;
        OleDbDataAdapter oledbda;
        string str;
        DataSet ds;
        DataTable dt;
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            //listBox1.Items.Add("a");
            //listBox1.Items.Add("b");
            //listBox1.Items.Add("c");

            OleDbConnection con = new OleDbConnection(ConnectionString);
            con.Open();
            str = "select * from emp";
            com = new OleDbCommand(str, con);
            oledbda = new OleDbDataAdapter(com);
            ds = new DataSet();
            oledbda.Fill(ds, "emp");
            dt = ds.Tables["emp"];
            int i;
            for (i = 0; i <= dt.Rows.Count - 1; i++)
            {
                listBox1.Items.Add(dt.Rows[i].ItemArray[0]);
            }
           con.Close();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            OleDbConnection con = new OleDbConnection(ConnectionString);
            con.Open();
            str = "insert into emp1 values('" + listBox1.SelectedItem + "')";
            com = new OleDbCommand(str, con);
            com.ExecuteNonQuery();
            con.Close();
            MessageBox.Show("Records Successfuly Inserted");
        }
    }
}



Thanks

hi,

private void button1_Click(object sender, EventArgs e)
        { 
for(int i=0;i<listbox1.Items.Count;i++)         
          {
if(listbox1.Items[i].Selected==true)
{
            str = "insert into emp1 values('" + listBox1.Items[i].ToString() + "')";
            com = new OleDbCommand(str, con);
            com.ExecuteNonQuery();
}
}
       
            MessageBox.Show("Records Added Successfuly ");
        }

I tried d code u suggested but its showing an error near " listbox1.Items[i].Selected " after items[i]. in intellisence its not showing any option like selected. Is there any other solution?

I'd try using the ListBox.SelectedItems property instead:

private void button1_Click(object sender, EventArgs e)

{  

     for(int i = 0; i < listbox1.SelectedItems.Count; i++)          

     {

         str = "insert into emp1 values('" + listBox1.SelectedItems[i].ToString() + "')";

         com = new OleDbCommand(str, con);

         com.ExecuteNonQuery();

     }

        

     MessageBox.Show("Records Added Successfuly");

}
