  try this

  StringCollection idCollection = new StringCollection();
              string strID = string.Empty;
              for (int i = 0; i < Gridview1.Rows.Count; i++)
              {
                  // Programmatically access the CheckBox from the TemplateField
                  CheckBox  cb = (CheckBox)Gridview1.Rows[i].Cells[0].FindControl("checkseleted");
                  
                  
                  if (cb.Checked)
                  {
                     //Checked

  You  can use FindControl to get any controls inside gridview

   foreach (GridViewRow row inGridView1.Rows)
      {
        
       CheckBoxList cbl=  (CheckBoxList)row.FindControl("cbl1");

  //do your validation logic with cbl here

  }

  Mark as answer if my post helped you
