I realize this is an old discussion, but the solution did not work for me with v. 2.5. However, see: https://community.esri.com/thread/199802-time-slider-widget-customization-single-handle  ... View more

Hi Galen: I tried a number of things, and also mounted a question to this site. Finally  I was directed to an alternative in the Javascript API by an ESRI staff member. This seems custom-made for the situation where one wants the time slider to reference a single date or time rather than a range. It is counter intuitive in that it only works when the time layer on the map is configured as cumulative or "progressive." It is the timeSlider.singleThumbAsTimeInstant() function. See: TimeSlider | API Reference | ArcGIS API for JavaScript 3.21  Modify the createTimeSlider() function in Widget.js by adding the bottom line below (around line 299): ... this.timeSlider.setThumbMovingRate(props.thumbMovingRate); this.timeSlider.singleThumbAsTimeInstant(true); Cheers ...

Right. I created a new app from scratch and tried the widget but I still get two handles. I assume that your line of code worked for you? So I am not sure what is incorrect. There was another question on this site that suggested a change to the setThumbIndexes values: https://community.esri.com/message/592667  However that did not work for me either. Any advice much appreciated. thanks ... View more

Robert: stemapp widget folder: C:\arcgis_web_appbuilder_2.5\WebAppBuilderForArcGIS\client\stemapp\widgets Is that incorrect? Some other customizations do seem to be working. thanks ... View more

Hello Robert: Thanks very much for the reply. I added the one line as you suggested to the getTimeSliderProps function but this did not appear to change anything effectively on the widget. The  I am copying the whole function below to make sure I am not missing something else.  getTimeSliderProps: function() { if (!this._timeSliderPropsDef) { this._timeSliderPropsDef = new Deferred(); this.own(this._timeSliderPropsDef); //var itemInfo = map && map.itemInfo; this.timeProcesser.getTsPros().then(lang.hitch(this, function (tsProps) { if (null !== tsProps && (this.timeProcesser.needUpdateFullTime() || true === tsProps._needToFindDefaultInterval)) { this.timeProcesser._getUpdatedFullTime().then(lang.hitch(this, function (fullTimeExtent) { // Next line added to reduce handles to only one - see Geonet response R. Scheitlin tsProps.thumbCount = 1; var start = fullTimeExtent.startTime.getTime(); var end = fullTimeExtent.endTime.getTime(); if (tsProps.startTime > end || tsProps.endTime < start) { tsProps.startTime = start; tsProps.endTime = end; } else { if (tsProps.startTime < start) { tsProps.startTime = start; } if (tsProps.endTime > end) { tsProps.endTime = end; } } if (true === tsProps._needToFindDefaultInterval) { tsProps.timeStopInterval = this.timeProcesser.findDefaultInterval(fullTimeExtent); } this._timeSliderPropsDef.resolve(tsProps); })); } else { this._timeSliderPropsDef.resolve(tsProps); } })); } return this._timeSliderPropsDef; }, Thanks for any further suggestions you can make.

Thanks for your response Mike. On the first question: it is a definite problem that not only can one not specify a sort order for a given layer, but the default of the features sorting themselves according to default table order (ID) also does not occur. One has no control over the ordering of multiple coincident features, and when these are date-ordered the user sees them as randomly sorted instead of chronological. Just saying. ... View more

Is this answer still valid? I have the same issue.  It seems a basic requirement, especially when records are date-ordered. Alternatively, is there a way to pop-up a list of selected features identified by key field (date) rather than just using the arrow to scroll through the list? ... View more
