I am Creating employee and going to connect with employees designation.
Employees data stored in one file like name and other details.Designation stored in other. when I am creating employee name there i am displaying one combo box bounded with designation table.While I am creating employees designation is not there what I need in combo box, I created one button to create designation. When I click on that button I am calling designation create form. There I am Entering new designation. But that designation is not updating in combo box what I placed in employee creation form. So how to do that.

What I have tried:

I am not getting any idea how to refresh that combo box. I am refreshing that combobox every time when I am Loading the form.

You'll have to post the relevant bits of your code. We don't even know if this is a website or a desktop app.

I think the best option would be to create a refresh button just side of combobox, which when clicked calls the refresh function for the combobox.

Maybe it's simpler to use a DataGridView, example:

C#

using System;
using System.Configuration;
using System.Data;
using System.Data.Common;
using System.Data.SqlClient;
using System.Windows.Forms;

// Put below lines in a method
string customers = "SELECT * FROM Customers";

using (SqlConnection con = new SqlConnection("Data Source=MY-PCNAME;Initial Catalog=northwind;Integrated Security=True"))
{
	DataSet ds = new DataSet();
	SqlDataAdapter da = new SqlDataAdapter(customers, con);
	da.Fill(ds, "Customers");
	dataGridView.AutoGenerateColumns = true;
	dataGridView.DataSource = ds;
	dataGridView.DataMember = "Customers";
}
