Can someone please share a code block by which we can create a datagridview which has a two additional rows (giving details about the main row ) for every row in the datagridview .the new rows each must have two labels . I have to tried to find a similar example but failed to so . please help me out . Thanks in advance .

Hi @Rahul Kumar , Welcome to Microsoft Q&A.

I simulated the results you get using a dictionary.

Use the valuechange event to trigger the judgment.

Only when the current cell is the second column every 3 cells will be triggered:

using System.Collections.Generic;
using System.Windows.Forms;

namespace _6_14_x
{
    public partial class Form1 : Form
    {
        Dictionary<string, string> cusList = new Dictionary<string, string>();

        public Form1()
        {
            InitializeComponent();
        }
        private void Form1_Load(object sender, System.EventArgs e)
        {
            cusList.Add("deepak(market)", "21.00");
            cusList.Add("xxx(market)", "10.00");
        }
        private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
        {
            if (dataGridView1.SelectedCells.Count > 0)
            {

                DataGridViewCell selectedCell = dataGridView1.SelectedCells[0];

                if (selectedCell.ColumnIndex == 1 && (selectedCell.RowIndex % 3 == 0))
                {
                    string name = dataGridView1.Rows[selectedCell.RowIndex].Cells[0].Value.ToString();
                    cusList.TryGetValue(name, out string value);

                    string price = selectedCell.Value.ToString();
                    DataGridViewRow row1 = new DataGridViewRow();
                    row1.CreateCells(dataGridView1, $"Cur Bal:{value} Dr", "");

                    DataGridViewRow row2 = new DataGridViewRow();
                    row2.CreateCells(dataGridView1, "On Account", $"{price} cr");

                    dataGridView1.Rows.Add(row1);
                    dataGridView1.Rows.Add(row2);
                }
            }
        }
    }
}

This code only demonstrates how to add two required lines as needed, you also need to add reckless judgment as needed.

Best Regards,
