Following should help: How to get a CheckBox in a Winforms DataGridView to react to the first click[^]

Something like:

C#

private void EmployeesGrid_OnCellValueChanged(object sender, DataGridViewCellEventArgs e)
{
     if (e.ColumnIndex == 0 && e.RowIndex > -1)
     {
        bool selected = (bool)_gvEmployees[e.ColumnIndex, e.RowIndex].Value;
        _gvEmployees.Rows[e.RowIndex].DefaultCellStyle.BackColor = selected ? Color.Yellow : Color.White;
     }
}

If you want to find selected items in general, then loop through all rows and check checkbox value for each row and depending on the selection, use your logic.

Create Dataset and datatable Add the columns

C#

public Form1()
        {
            InitializeComponent();
            GINdata();
        }

        DataSet ds = new DataSet();
        DataTable dt = new DataTable();

        public DataTable GINdata()
        {
            dt.Columns.Add(new DataColumn("vname", typeof(System.String)));
            dt.Columns.Add(new DataColumn("Rate", typeof(System.String)));

            return dt;
        }

Add One button

in btn Click if check box is placed in cells[2] then write this code

for (int i = dataGridView1.Rows.Count - 1; i >= 0; i--)
{
if ((bool)dataGridView1.Rows[i].Cells[2].FormattedValue)
{

DataRow dr = dt.NewRow();

dr["vname"] = dataGridView1.Rows[i].Cells["vname"].Value;
dr["Rate"] = dataGridView1.Rows[i].Cells["Rate"].Value;

dt.Rows.Add(dr);
}
--------------------------------

Add the datatable into dataset
ds.Tables.Add(dt);
string XML = ds.GetXml();
MessageBox.Show(XML);
