   Hello, We have a custom listview template . How do I access the data from this listview to place conditions on the value of the fields, if it isnt in a standard listview widget?. I.e. Logic will be placed on the value of the statuscode (below)  
     eg
   #if(statuscode){#
                  <span>#:statuscode#</span>
               #}#
   Thanks

   Hi Chris
   
   Could you clarify what you mean by "if it isnt in a standard listview widget"? But this document may help you to access data from listview for now:

   We've also written blog articles about the listview and other tips on using the TPC:

   Hi Omar,
   Sorry I meant it was a customised widget.
   I am still having trouble accessing the datasource through javascript on the page. I can access the datasource when looking through Chrome Dev tools, but not by the JS written into the page itself.
   Other widgets dont have this same issue. Why would that be? Have you got more examples of accessing the listview data source?
   Thanks Chris

   Hi Chris
   
   So as long as you load your fetch and the fetch contains the attributes you want, then data from the table/entity should be accessible. As a simple example, here is a fetch that retrieves the fullname attribute from the Contact entity: 
   
   <fetch version="1.0" output-format="xml-platform" mapping="logical">
     <entity name="contact">
       <attribute name="fullname" />
       <attribute name="contactid" />
       <order attribute="fullname" descending="false" />
     </entity>
   </fetch>
   
   In the custom listview editor, inside the list item I am able to access the fullname attribute and manipulate the UI doing the following:
               <li class="list-group-item d-flex justify-content-between align-items-center">
                    #if(fullname.includes("Chris")){#
                                   <span style="color: green">#: fullname #</span>
                               #}else{#
                                   <span style="color: pink">#: fullname #</span>
                               #}#
   
   If you are still having issues, please feel free to respond back with your fetch query, your js code placed inside the listview, and any console errors, You can also email us at

   Thanks Omar,
   Yes I have now added logic into the template, which works. I was attempting to add the javascript into a script widget and keep it all together, but this will do.
   Thanks

   I see what you mean. To access the datasource after the listview has been rendered, you can do something like this inside the script widget; 
   
   tpc.page.TpcListViewModel.get_listView().dataSource.data()

   Thanks Omar. The frustrating thing is, I can use this line to access the data from Chrome Dev tools but the same code retrieves a null-result from the javascript written in the page widget code.
   I do not know why this is.

   Oh, that is frustrating indeed. I'm sorry I didn't understand that this was your issue. 
   
   But to answer your question, it's likely b/c your listview hasn't been generated before the JS code can take effect; so, the JS is calling on a non-existent datasource. Try nesting your code inside a tpc:ready event.  
   
   $(document).on("tpc:ready", function(){
     console.log("All TPC Widgets have been Initialized");
     tpc.page.TpcListViewModel.get_listView().dataSource.data()
   });

   Thanks Omar, unfortunately that didnt work either.
   
   $(document).on("tpc:ready", function(event, tpcObject){
   console.log("All TPC Widgets have been Initialized");
   
   console.log(event); //tpc:ready Event
   console.log(tpcObject); //TPC Window Object
     var notes = tpc.forms[0].notes;
   console.log(notes);
   var notesData = notes.get_listView().dataSource.data();
   var length = notesData.length;
   console.log(length);
   });
