如果有帮助，请尝试此操作.

Hi,

Try this if could help.

//instantiate new ArrayList to hold our checked items
ArrayList checkedItems = new ArrayList();
CheckBox chk;
string chkBoxIndex = string.Empty;
//loop through each row in the GridView
foreach (GridViewRow row in grdEmployee.Rows)
{
   //get the index of the current CheckBox
   chkBoxIndex = (string)grdEmployee.DataKeys[row.RowIndex].Value.ToString();
   chk = (CheckBox)row.FindControl("CheckBox1");
   if (!(Session["CheckedItems"] == null))
   {
      checkedItems = (ArrayList)Session["CheckedItems"];
   }
   if (chk.Checked)
   {
      if (!(checkedItems.Contains(chkBoxIndex)))
      {
         //add to the list
         checkedItems.Add(chkBoxIndex);
      }
      else
      {
           //remove from list since it's unchecked
           checkedItems.Remove(chkBoxIndex);
      }
    }
 }
 var counts = checkedItems.Count;
 // Now Check the contains of the checkedItems
 // Should contains the Primary Index key...

如果可以的话请投票...
