I am converting Infragistics 2010 v2 CLR3.5 to Infragistics 2014 v2 using 4.5 CLR using Visual Studio 2013 Professional Update 4. I am getting following error while building the project. Please reply immediately..........

Error 295 'Infragistics.Web.UI.GridControls.GridField' does not contain a definition for 'FieldLen' and no extension method 'FieldLen' accepting a first argument of type 'Infragistics.Web.UI.GridControls.GridField' could be found (are you missing a using directive or an assembly reference?)

Below is the error coming while fixing using WebDataGrid.........

GridRecordItem gCell = uGrid.Rows[i].Cells[j];
 
      gCell.Style.Reset();
 
         if (flgReplace && gCol.Index == j)  //all the values without search
         {
          if (btnAction == "Find")
             gCell.Style.BackColor = Color.FromArgb(255, 211, 137);
             flgNotFound = false;
             if (btnAction == "ReplaceAll" && gCell.IsEditable())
             {
               bool checkType;
                 if (replaceTxt.Length > gCell.Column.FieldLen)
                 {
                  //replaceTxt = replaceTxt.Substring(0,gCell.Column.FieldLen);
                  alertMsg = "Replace With value exceeds the maximum allowable field length : " + gCell.Column.FieldLen;
                  checkType = false;
                 }
                  else if (gCell.Column.DataType == "System.DateTime")
                 {
                  checkType = DMSCommon.CheckDate(replaceTxt);
                  alertMsg = "Enter correct DateTime value";
                  }
                  else if (gCell.Column.DataType == "NUMBER")
                  {
                  checkType = DMSCommon.IsNumeric(replaceTxt);
                  alertMsg = "Enter correct Number value";
                  }
                  else
                   checkType = true;
                   if (checkType)
                  {
                  gCell.Style.BackColor = Color.FromArgb(255, 211, 137);
                  gCell.Value = replaceTxt;
                  StoreGridChanges(totalCol, gridID, uGrid.Rows[i], dt);
                  cntModified++;
