HI
Please assist in re-write the following code (especially the if statement part) such that it uses a while loop to check if the enough "delegates" were captured and populates on list box lstDelegates:

C#

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Ingwenyama
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        string OrganiserName, IDNumber, Contact, Nationality;
        int NumDays, NumDelegates;
       //int NumD;
        private void btnCapture_Click(object sender, EventArgs e)
        {

            populateDelegates(4);
            //radImbizo.Checked = false;
            //NumDelegates++;

        }

        private void radImbizo_CheckedChanged(object sender, EventArgs e)
        {
            txtDelegate.Enabled = true;

        }

        public int numDelegate(int num)
        {
            return NumDelegates = NumDelegates + 1;
        }

        public void populateDelegates(int maxDelegates)
        {
            lstDelegates.Items.Add(txtDelegate.Text);
            txtDelegate.Enabled = false;
            //NumDelegates = 0;
            if (NumDelegates < maxDelegates)
            {
                txtDelegate.Enabled = true;
                numDelegate(NumDelegates);
                txtDelegate.Clear();
                txtDelegate.Focus();

                //
            }
            else
            {
                txtDelegate.Enabled = false;
                btnCapture.Enabled = false;
            }
        }

       

}

How and where do you want it done? Do you want it to loop through and progressively add more delegates? Or do you want it to just keep checking the variable and wait until it has enough?

Where are you stuck? Why can't you do it?

Where is the text for Delegates coming from? Your code is just adding one Delegate to the list. This method isn't needed:

C#

numDelegate(int num)

Your while loop would be like this:

C#

private void buttonCapture_Click(object sender, EventArgs e)
        {
            populateDelegates(4);
        }

        private void populateDelegates(int maxDelegates)
        {
            this.numDelegates = 0;
            this.listBox1.Items.Clear();
            while (numDelegates < maxDelegates)
            {
                this.listBox1.Items.Add("Delegate " + numDelegates.ToString());
                numDelegates++;
            }

        }
