RelationshipQuery using 4.10

ToddFagin — Wed, 20 Feb 2019 19:21:17 GMT

Quick background. I currently have a feature layer that represents insect traps (this is a mock dataset with just two points for now). Occasionally, field technicians will go and inspect the traps and record the findings in a related table (we will ultimately use Collector for this). I am also developing an associated webapp. I would like to use JSAPI 4.10 to enable a user to click on a feature and the related table (showing the field inspections) open.

This is actually something I previously did on another project using 3.15 in conjunction with bootstrap. When I update this old code with the new feature layer, it still works in 3.15. However, since I plan to integrate this into a larger app utilizing the newer version of the API, I would like to update it to 4.10. Thus far, I have failed miserably in this regard. Additionally, there may be a far more elegant and straightforward solution than I am trying to use, but I cannot find any examples (which I need since I follow the mantra of "code by cannibalization" since I really don't know what I am doing--ha)!!! For instance, here is a real simply web map I made in ArcGIS Online that has a popup with the option to show related records that, when clicked, the related table opens. I oh so want to believe there is a straight forward way to do this with the JSAPI.

Below are two examples that I have. The first uses 3.15 and works. The second 4.10 and doesn't work. As I said, though, if there are better solutions out there, I would gladly explore those.

Example 1: This works (but I don't have an option to close the table, which is another issue, but not the one I am addressing now)

Todd,

You weren't to far off. Mainly your issue was understanding that layer do not have a click event in 4.x:

Thank you for the reply and assistance.

Immediately after posting, I had to head out of the office for a conference. It will likely be a day or two before I get to dig into this. Nonetheless, in the meantime, I wanted to express my gratitude.

Take care,

Todd

Done.

As an aside, and I will dig deeper later, when I found this Bootstrap solution three or four years ago, I recall it was a necessary workaround because the then current API didn't handle what I wanted to do (I could be wrong there).

If possible, I would like to stay primarily (or solely) within the 4.10 API (this is just because of my limited skills and knowledge in these regards--It makes my life somewhat easier). Is there any solution you would recommend beyond this hack. I am just wanting a pointer here--everything I do comes from modifying other examples I have found elsewhere. There are likely many examples I am overlooking.

As always, much appreciated.

Re: RelationshipQuery using 4.10

This is fantastic. Thank you for taking the time to do this. I am now looking into dgrid trying to learn more about it.

Re: RelationshipQuery using 4.10

ToddFagin — Fri, 22 Feb 2019 14:20:55 GMT

Once again, this is great.

I made a small addition for anyone else who may stumble across this thread.

For some reason (the best I can tell, at least) dgrid doesn't have a way to close the data grid once opened. The easy fix for me was to add a button with a tiny bit of JS to the gridDisplay div:

<div id="gridDisplay">
       <button class="button" onclick="document.getElementById('gridDisplay').style.display='none'" >x</button>
      <div id="grid"></div>
    </div>

I don't know if this is the most elegant solution, but it works.

Thanks again for your assistance.
