  How bind RadDropDown to a complex Json string

  Nov 05, 2018 10:38 AM|shashikant2011|LINK

  hi, I have following JSON string but unable to bind it :

  JSON string : 

  var result ="{\"GroupDispositions\":[{\"Code\":\"C\",\"Description\":\"CONTACTED\"},{\"Code\":\"NC\",\"Description\":\"NOT CONTACTED\"}],\"Response\":[{\"ResultCode\":\"0\",\"ResultString\":\"Pass\"}]}";

  
  Here is my Code:

  function OnSuccess_FillDispositions(result) {
              try {
                  if (result == null)
                      return;
                  var items = result.d || result;
                  var combo = $find('<%=cmbMainDisposition.ClientID %>');
                  var combosubsub = $find("<%= cmbSubSubDisposition.ClientID %>");
                  // alert(combo);
                  if (combo != null) {
                      combo.clearItems();
                      combosubsub.clearItems();
                      combosubsub.clearSelection();
                     
                      for (var rowIndex = 0; rowIndex < result.length; rowIndex++) {
                          var row = result[rowIndex];
                          var comboItem = new Telerik.Web.UI.RadComboBoxItem();
                          comboItem.set_value(row.Code);
                          comboItem.set_text(row.Description);
                          comboItem.get_attributes().setAttribute("Code", row.Code);
                          combo.get_items().add(comboItem);
                      }
                  }
                  combo.get_items().getItem(0).select();
  
  
              }

  Please help!

  following JSON string but unable to bind it :

  Try parsing the Json to javascript object and then loop thorugh GroupDispostion array to access code and descriptions

  Try with below code

  function OnSuccess_FillDispositions(result) {
                      try {
                          if (result == null)
                              return;
                          var items = result.d || result;
                          var combo = $find('<%=cmbMainDisposition.ClientID %>');
                          var combosubsub = $find("<%= cmbSubSubDisposition.ClientID %>");
                          // alert(combo);
                          if (combo != null) {
                              combo.clearItems();
                              combosubsub.clearItems();
                              combosubsub.clearSelection();
                              //Parse the Json string
                              var parsedResult = JSON.parse(result);
                              //Loop through GroupDispositions and assign the value
                              for (var rowIndex = 0; rowIndex <= parsedResult.GroupDispositions.length; rowIndex++) {
                                  var row = result[rowIndex];
                                  var comboItem = new Telerik.Web.UI.RadComboBoxItem();
                                  comboItem.set_value(parsedResult.GroupDispositions[rowIndex].Code);
                                  comboItem.set_text(parsedResult.GroupDispositions[rowIndex].Description);
                                  comboItem.get_attributes().setAttribute("Code", parsedResult.GroupDispositions[rowIndex].Code);
                                  combo.get_items().add(comboItem);
                              }
                          }
                          combo.get_items().getItem(0).select();
                      }
