This Data Table will bind to DataGridView.

         /// <summary>
         /// Create DataTable to add to DataGridView
         /// </summary>
         /// <returns>DataTabe</returns>
         private DataTable SampleDataTable()
         {
             DataTable dt = new DataTable("MyDataTable");

              //Create columns and add to DataTable;

              DataColumn dcID = new DataColumn("ID");
              dt.Columns.Add(dcID); //ID column created and add to DataTable

              DataColumn dcSomeText = new DataColumn("SomeText");
              dt.Columns.Add(dcSomeText); //LastName column created and add to
DataTable

              //Now Add some data to the DataTable
              DataRow dr;
              for (int count = 0; count <= 9; count++)
              {
                  dr = dt.NewRow();
                  dr["ID"] = count;
                  dr["SomeText"] = "Some Text " + count;
                  dt.Rows.Add(dr);
              }

         }


On the FormLoad_Event add this line of code to bind SampleDataTable() as a datasource of
of windows application like this

private void Form1_Load(object sender, EventArgs e)
{
      myDataGridView.DataSource = SampleDataTable();

Now on Button click Event add this line of code to check what all rows user has selected
from DataGridView.

private void btnSubmit_Click(object sender, EventArgs e)
{
     foreach (DataGridViewRow dr in myDataGridView.Rows)
     {
         if(dr.Cells[0].Value != null) //Cells[0] Because in cell 0th cell we
have added checkbox
          {
                    MessageBox.Show("Rows " +dr.Index + " selected");
          }
