I am having a problem when i delete a database record in win form. After successfully deleting a record, it show in the form unless i close the form and reload it again. Is there any method in C# by which we can refresh the table without restarting the form?

C#

private void cmddelete_Click(object sender, EventArgs e)
       {
           SqlConnection conn = new SqlConnection(@"Data Source=MANISH-PC\SQLEXPRESS;Initial Catalog=Leavemanagement;Integrated Security=True;Pooling=False");
           conn.Open();
           SqlCommand command = new SqlCommand("delete from Emp_Details where id=@id",conn);
           command.Parameters.AddWithValue("id", txtempid.Text);
           SqlDataAdapter adp = new SqlDataAdapter(command);
           command.ExecuteNonQuery();
           MessageBox.Show("successfully Deleted");
           Refresh();
           conn.Close();
       }

Hi guru,
Better you write a select query after MessageBox.Show("successfully Deleted");
like

C#

DataTable dt=ne DataTable():
SqlCommand command = new SqlCommand("Select * from Emp_Details");
SqlDataAdapter adp = new SqlDataAdapter(command,conn);
adp.Fill(dt);

Now use the data present in the datatable dt.
u will get the records except deleted record.
