if (DataList1.Items.Count == 0)
            {
                msgError.Text = "Please add images and captions for each image";
                msgError.Focus();
            }
        else 
            AddCaption();
            bool IsEmptyCaption = false;
            Hashtable htble = (Hashtable)ViewState["imgIdCapHtbl"];
            List<int> imgIds = (List<int>)ViewState["imgIds"];

            if (htble != null && imgIds != null)
            {
                foreach (int id in imgIds)
                {
                    if (htble[id] == "")
                    {
                        IsEmptyCaption = true;
                        break;
                    }
                    else
                        IsEmptyCaption = false;

                }

Now its working fine...
