What is the error?  I'm not familiar with visual studio, but can you mouse over the underlined code to display the error? ... View more

I've noticed this.  It seems to have to do with the order that the elevation and the labels are drawn.  As you zoom in and out, the elevation updates and the terrain will shift.  The labels appear not to be shifting with the terrain. ... View more

How is the first user "passing the items" to the second user? My initial reaction is that the right way to do this is to pass a query around.  So, user A picks out 3 items from their contents and you build a query that searches ArcGIS Online, something like: id: <item_1_id> OR id: <item_2_id> OR id: <item_3_id> Then user B, who is viewing the items, executes the query that user A built.  They will only get a response for items that they have access to. ...

One option would just be to adjust the time.  IE: make it night time at the user's position when night is toggled on and make it day time when day is toggled on. I don't know of a way to influence ambient light. ... View more

There doesn't seem to be a lot of user-facing options for these things. There are various things you could do to obstruct the scene from shadowing the side of the earth opposite the sun.  For example: JS Bin - Collaborative JavaScript Debugging  That sample modifies a function on the environment manager so that it doesn't have a reference position for the camera and therefore falls back to generic lighting settings (entire earth is illuminated).  It's not clear to me that's what you're looking for, though. One option would be to call that code to modify that function under certain circumstances and then revert to the prototype function when you want normal lighting to resume. It can be "dangerous" to play with this kind of stuff as a bug in your codes results in the view freezing with no error message. ... View more

Hmm, that's a harder problem.  Thinking about it, there should be a way to figure out of the center of each tile if you know the row, column, origin, and resolution. Speaking generally, I would think that the x, y would be (col + .5) * resolution, (row + .5) * resolution (assuming the tile coordinates are 0 based).  But I'm unsure how the "tile grid" is oriented compared to the web mercator x, y axis.  Maybe you can figure this out based on the origin that is passed into the TileInfo. I'll take a look at the source code and see if I can find an example of this being done. ... View more

Here's my attempt to reproduce: JS Bin - Collaborative JavaScript Debugging - click map to perform a search.  Everything seems to be working normally.  I'm only doing this for a single point feature service though. I would try calling graphicsLayer.add() for each graphic in the returned featureSet rather than setting the .graphics property equal to featureSet.features.  I couldn't get the "highlight" graphics to show up at all, even with a redraw, using the method you posted. ...

Thanks for the information, I'll try to reproduce this later today. ... View more

Here's a sample that draws each tile's extent as the tiles update (ie as you zoom in and out) JS Bin - Collaborative JavaScript Debugging  You could draw the center of each extent rather than the extent itself. ... View more

I've run into a similar issue that may or may not be related (in my case I didn't notice any relation to zoom scale).  I was creating a graphics layer, adding graphics to it, clearing it, and adding more graphics all within a very small timespan.  The result was that some graphics would get "stuck" nondeterministically (from my perspective anyway) i.e. they'd be visible in the view but were nowhere to be found in any graphics collection, and calling graphicsLayer.clear() did nothing. I fixed this by ensuring that the graphics were not cleared and added within the same fraction of a second (about 100 ms). The thing to do is probably to try to reproduce this in a sandbox: 1.  You're using the 4.4 API, correct?  Map View or Scene View? 2.  What method are you using to search for nearest graphics? 3.  What method are you using to highlight graphics? 4.  The graphics layer in question holds the highlights, correct? Any sample code or pseudocode would also be helpful to replicate this. ... View more

Your sample seems to work fine for me (checked with chrome and firefox).   ... View more
