I am populating my combobox with table's data (example table name is "ITEMS" and table is having only one column and that is displayed as combobox items). In my form i am having i combobox,button and textbox. I will enter a new item in textbox and if i click on button, that new item will be stored in a table i.e. "ITEMS"). my problem is that new item has to be displayed in combobox items without closing my form and again opening it.
If i click button by entering new item in textbox that value has to be stored in table and combobox has to be populated with new item.

A form doesn't close by itself. Could you send your code with the eventhandler of the button?

When you "open" the form, include as part of the calling to open method an update of your combobox items.

Yo dude, you can always just refresh the connection, you don't need to close your form,

i take it you want something like this

using System.Data.SqlClient;

namespace TestDummyTWO
    public partial class Form1 : Form
        SqlConnection sqlcon =
            new SqlConnection("Data Source=.;Initial Catalog=your_table;Integrated Security=True;Asynchronous Processing = True");

        SqlCommand sqlCom = new SqlCommand("SELECT ITEMS FROM YOUR_TABLENAME");

        public Form1()

        private void Form1_Load(object sender, EventArgs e)
            SqlDataReader reader = sqlCom .ExecuteReader();

            // Looping throuhg the list of data
            while (reader.Read())
                // Fill combo Box with data

        private void button1_Click(object sender, EventArgs e)
            // you added the new item from the tex box into the DATA TABLE
            // Not the combobox
            // use sqlCom again to do so

            sqlCom.CommandText = "Insert into blah blah";

            /* THIS IS WHAT YOU HAVE TO DO */

Hope that helps ...

Thanks alot. it worked for me
