Links for October 4, 2011

Not a question, but after a few weeks of implementing simile timeline I've got a few tricks for any C# ASP.NET users out there.  First, if you're using masterpages you absolutely have to link to the timeline-api.js in the server side head tag in the Masterpage.  I tried putting it in the aspx page, the user control, no luck, has to be in the masterpage.  All other javascript can be in the page/ control.  Second, I needed to create a user control that could be dropped onto several pages that loads data dynamically, as in I couldn't just point to an XML file like all the examples show.  Here is some code for dynamically generating Events in the code behind and passing them to the javascript on the client.  In the onLoad function:  function onLoad() {   var eventSource = new Timeline.DefaultEventSource();    // this will be populated by code behind, it is the list of events   <%= DCEvents %>  ..... all the other code for creating the zones, timeline, etc .....  }  In the code behind, have a property called DCEvents:      private string _DCEvents;     public string DCEvents     {         get         {             return _DCEvents;         }         set         {             _DCEvents = value;         }     }   Then on page load fill DCEvents, for my purposes I'm getting an array of "streams" that have an attribute of "createDate", but you can loop through a dataset or generic list or anything you want:               StringBuilder sb = new StringBuilder();              // get the streams, here just do whatever you need to get your data             streams = mgmt.getDatastreamHistory(pid, dsid);              // loop through your data creating an Event for each row, again your data object will be different             foreach (FedoraManagement.Datastream stream in streams)             {                 string Date = DateTime.Parse (stream.createDate).ToString("MMM dd yyyy 00:00:00 EST");                  sb.AppendLine("var dateEvent = new Date(\"" + Date + "\");");                 sb.AppendLine("var evt = new Timeline.DefaultEventSource.Event(");                 sb.AppendLine("dateEvent, //start");                 sb.AppendLine("dateEvent, //end");                 sb.AppendLine("dateEvent, //latestStart");                 sb.AppendLine("dateEvent, //earliestEnd");                 sb.AppendLine("true, //instant");                 sb.AppendLine("\"My Title\",");                 sb.AppendLine("\"<a href=javascript:__doPostBack('" + stream.createDate + "')>This is a Postback</a>\");");                 sb.AppendLine("eventSource.add(evt);");                 sb.AppendLine(" ");             }              // finally fill your property with this string             this.DCEvents = sb.ToString();   For every event this will now show up in your onLoad function as seen in Firebug (the postback line is simply the text of the popup, I needed a postback link):  var dateEvent = new Date("Mar 02 2009 00:00:00 EST"); var evt = new Timeline.DefaultEventSource.Event( dateEvent, //start dateEvent, //end dateEvent, //latestStart dateEvent, //earliestEnd true, //instant "My Title", "<a href=javascript:__doPostBack('2009-03-02T19:28:59.365Z')>This is a Postback</a>"); eventSource.add(evt);   Lastly here is the postback function, because it took a long stinkin time to get a postback working:  function __doPostBack(eventArgument) {   var theform = document.aspnetForm   theform.__EVENTTARGET.value = theform   theform.__EVENTARGUMENT.value = eventArgument   theform.submit() }  Its now working and I gotta say its pretty sweet, let me know if you've got any questions. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups  "SIMILE Widgets" group.
