number to be displayed in the textbox

As Satyapriya says the question is not very clear but, if I've understood it correctly, the code will be something like this.


The skeleton eventhandlers should be added from the VS designer, not just typed in manually:


        private void Form1_Load(object sender, EventArgs e)
        {
            int[] numbers = new int[29];
            for (int i = 0; i < 29; i++) numbers[i] = i + 1;
            comboBox1.DataSource = numbers;
        }


        private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            int index = comboBox1.SelectedIndex;
            if (index == -1) return;
            textBox1.Text = (index + 1).ToString();
        }


        private void comboBox1_TextUpdate(object sender, EventArgs e)
        {
            textBox1.Text = comboBox1.Text;
        }

Hi Rao,

Make sure the title of question makes sense. "g" does not make sense.

Please  elaborate it deep and clearly.



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;

namespace Sum_in_datagridview
{
  public partial class Form5 : Form
  {
  public Form5()
  {
  InitializeComponent();
  }

  private void Form5_Load(object sender, EventArgs e)
  {
  int i;
  for (i = 1; i <= 29; i++)
  {
  comboBox1.Items.Add(i);
  }
  }

  private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
  {
  textBox1.Text = comboBox1.Text;
  }
  }
}



Thanks
