单击添加按钮后

After clicking on add button

       {
           List<FmlDiseaseHist> fmlDiseaseList = new List<FmlDiseaseHist>();
           FmlDiseaseHist objFmlDiseaseHist = new FmlDiseaseHist();
           if (chkAddMandatory() == true)
           {
               if (Session["FmlHist"] != null)
               {
                   fmlDiseaseList = (List<FmlDiseaseHist>)(Session["FmlHist"]);
               }

               if (string.IsNullOrEmpty(txtRelation.Text) != true)
               {
                   objFmlDiseaseHist.Relationship = Convert.ToString(txtRelation.Text);
               }
               if (string.IsNullOrEmpty(txtFmlDate.Text) != true)
               {
                   objFmlDiseaseHist.Dates = txtFmlDate.Text;
