Highlighting features
Hi,
There have been a few questions about highlighting and selection lately, and I thought I'd address the issue at once in a new topic.
Highlighting is currently not supported in the Geocortex Viewer for HTML5 version 1.1, but is a priority item on the version 1.2 schedule. We plan on offering an API that matches what is currently present in the Geocortex Viewer for Silverlight, as well as building upon it and offering a UI experience that works as well on smartphones as it does on PCs.
Hopefully this clears up some confusion and questions about highlighting. Thanks for your feedback!

Thank you very much for the information, Jason.

Thanks Jason. Speaking of Smartphones, it seems that the HTML5 viewer works much better on Tablets then on Smartphones... Is that reality, or just my imagination?

Hi Mike. Since smartphones typically have less processing power, less memory, and less GPU throughput, it's usually pretty safe to assume that there are going to be some differences in performance. On top of that, smartphones obviously have less screen real-estate to work with. In general, it's pretty safe to say that most apps work better in general on tablets than on smartphones. Particularly in the case of visually oriented applications like GIS viewers.

It is pretty clunky on my smartphone - almost un-usable. Are there any plans to optimize this for smartphones at some point? Also, any idea why pinch-to-zoom does not work on these maps with my android phone, when it works on other websites? Someone with an iPhone was able to pinch-to-zoom on these maps...

The viewer is in fact optimized for smartphones. We've created an entire UI specifically for them, and our JavaScript/HTML framework was built specifically with performance on mobile devices in mind.
Performance of the actual map control will varies between different devices due to OS version, device hardware, and browser. On newer iOS devices, for example, it is very smooth and responsive. This is due to the browser on the device being able to use hardware acceleration while drawing the map. Many Android devices don't have such robust hardware acceleration at this point, in the stock browser. You may wish to try a different browser (e.g. Chrome, Firefox for Android) and see if that helps.
Pinch to zoom (a multi-touch gesture) indeed works on iOS devices, but often doesn't work on others. I know that on some older devices multi-touch was supported by the hardware, but was not used in the browser due to some patents held by Apple. Newer Android version support multi-touch UIs, but it's up to the ESRI map control to handle it in the given browser.

Jason,
I've a relatively new Sumsung Galaxy Nexus, with Android version 4.1.1 and I'm using Chrome as the browser. I'm able to use Pinch to zoom on other web sites, but not this one.

Multi-touch support in the browser on Android is not consistent between OS versions and devices. This is the reason the map control doesn't support it. There is more info here: http://forums.arcgis.com/threads/52019-Zooming-gestures-on-Android, as well as some potential workarounds.

Is the Map Control an ESRI thing, or something of yours? If it is something of yours, do you foresee supporting Android zooming anytime soon? Why does it work in other sites? I'm not a programmer anymore, so did not follow the conversation 100% in the link you provided. Would I need to modify the Index.html using Visual Studio?

It looks as though support for pinch/zoom is included in ESRI's JSAPI 3.2:

Does that mean that the HTML5 viewer is using an older JSAPI than 3.2? Is there any way we can upgrade, or is it something that LG will have to write into their viewer?

You can open your HTML files (Index.html, Tablet.html, Handheld.html) and change the API version there, if you like. Search for "3.1".
A word of warning: 3.2 is quite new and we have barely begun testing against it.

I went ahead and changed Handheld.html and pinch to zoom now works. Thanks. I'll let you know if I see any quirks with 3.2...

Jason - fatal flaw with 3.2 - cached tiles do not come in properly... Oh well, I'm back to 3.1./customer/servlet/servlet.FileDownload?file=00P6000000e888ZEAQ

Do your tiled services look anything like what's on this page: http://help.arcgis.com/en/webapi/javascript/arcgis/help/jshelp/whats_new.html ? Perhaps they don't show up at all?
Try including "esri.css", like as mentioned on the What's New page: http://help.arcgis.com/en/webapi/javascript/arcgis/help/jshelp/whats_new.html
I dropped the following into the <head> of my document (look for the other <link> elements), and it worked for me:
<link rel="Stylesheet" href="http://serverapi.arcgisonline.com/jsapi/arcgis/3.2/js/esri/css/esri.css" />

Jason, thanks, that worked for me as well, once I changed "Stylesheet" to "stylesheet" - I'll let you know if anything else turns up.

Yes - perfect. I think we just secured a Geocortex sale on that configuration change. /customer/servlet/servlet.FileDownload?file=00P6000000e87wBEAQ

Any update on this topic (specifically referring to the ability to change highlight border and fill colours). we are running 1.2. can;t seem to find a way to replicate silverlight functionality in html5.

I'm running a workflow and can't get the HTML 5 viewer to highlight either SL viewer does it just fine with the same workflow
but not Html 5 will this be fixed?0 -
I agree with Cattyann. It would be very nice to have the highlight work with Workflow, as it does with the Silverlight Viewer.

At least the little red pin is working now so I'm not totally unhappy
but highlights would be most welcome.0 -
I am using HTML5 2.2 and am unable to highlight any features in my workflow. In the HTML developer guide (pg 162) it lists all the supported commands for highlighting. I tried all the ones that didn't say they weren't supported in workflows and I couldn't get it to work. I even specified the fill and border color and everything.

I'm running a workflow in GHV 2.4 (Essentials 4.3) using the standard sequence below to highlight features selected using the "Display Capture Geometry" activity.
"CreateHighlightLayer"
highlightLayer"SetActiveHighlightLayer"
highlightLayer"HighlightEsriFeatureSet"
yourfeatursetI read that "highlighting" in HTML5 was going to be support in the later versions (> 1.1), however, this is my first time to use this sequence in a workflow. Does anyone know if this ever got implemented or if there is there something else I need to add to the sequence.
Thanks for your help.

Hello I'm using the HTML5 2.5.2 GHV (Essentials 4.4.3) when using workflows I can't get a polygon feature to highlight from a select unless I select it in the results pane. Is there a way to get the polygon to highlight when selected without having to select it in teh results pane? I have configured the pushpin option to "true" to show a pushpin. I tried the Create HighlightLayer, Set ActiveHIghlightLayer, HighlightEsriFeatureset activities as well as different expressions in the expression editor for the pushpin, but no luck, any leads would be appreciated. 0 -
Oscar, any luck? I am trying to do the same thing. 0 -
We are now in HTML5 2.6.1 and this highlighting feature still is not working. Any suggestions? 0 -
@Latitude:This functionality is imparative for us to migrate our several of our silverlight viewers to HTML5. Is this going to be an added feature soon? 0 -
Hi Oscar and others, I've cover a work around for highlighting features in following discussion https://support.geocortex.com/EssentialsGSCForum?id=9066000000007YiAAI
Hope it helps.0
