I have a datatable with the values (1.0,0.98,0.78,0.8549996).I had created a dropdownlist for these values to be binded to the gridview. In the gridview the values are displayed as (100,98,78,85).

So My problem is everything works fyn for me except 100 & 85..At this case(100,85) gridivew is not ddl is not displayed to my gridview.

public void bindddlscore()
       {
           try
           {
               DataTable dtscore = (DataTable)Session["GrdSearch"];
               DataTable dtscore1 = new DataTable();
               dtscore1.Columns.Add("DisplayMember", typeof(int));
               dtscore1.Columns.Add("ValueMember", typeof(float));
               foreach (DataRow item in dtscore.Rows)
               {
                   dtscore1.Rows.Add(Convert.ToString(Convert.ToInt32(Convert.ToDecimal(item["Score"]) * 100)), item["Score"]);
               }
               ddlscore.DataSource = dtscore1.DefaultView.ToTable(true, "DisplayMember", "ValueMember");
               ddlscore.DataTextField = "DisplayMember";
               //ddlscore.DataTextFormatString = "{0:N}";
               ddlscore.DataValueField = "ValueMember";
               ddlscore.DataBind();
               ddlscore.Items.Insert(0, "All");
           }
           catch (Exception ex)
           {
               throw ex;
           }
       }
