Drilling and Interactivity across pages

[marco6]

Hi all!

Currently I am developing a custom visual for one of my clients. One of the features that I need is to drilldown on click of a data point. A behavior like the "histogram" default component would be perfect (the user can select data, then if [s]he clicks on "drill mode" can drill down contextual data).

Trying out the sampleBarChart component from the Microsoft's tutorial, I get a strange behavior:

- In PowerBI Desktop everything works as expected.

- In PowerBI Online (IE11/FF/Chrome) it does nothing.

Strangely enough, if I manually force the refresh of the data (by for example resising the visual - edit mode only) I get the right data! For this reason I guess a possible workaround would be a simple refresh... But AFAIK it is not possible to trigger a refresh on a visual by code...

I am attaching a pbix with a dumb dataset to reproduce the issue. I had to enable drilldown on the sampleBarChart visual: I simply added

"drilldown": {
	"roles": ["category"]
},

in the capabilities and built it.

Can anybody help?

@marco6,

It seems to be a limitation, try to leave a comment on GitHub.

Hi! Thank you for you answer!

Checking thoroughly the behavior of the visual, I managed to get the same behavior using just the drilldown controls (nothing custom at all this time: no selection, no contextual drilldown, no events on my custom visual fired... And no refresh until resize!). It seams to me much more like a bug than a limitation. I made a quick scheme of what the behavior I get and I attached to this message.

As you can see, when I expand to the next level, the controls and the title understand the change and are able to update, but the data isn't. I get no update event (I am logging every event). Moreover, clicking "update" has no effect on the visual (once it gets in that state it is "stuck" there until resize: I get no "update" event), while in a normal situation (and also after resize) I get normal events on "update" as well.

I have written in the "issue" section of this community website this problem, but since last ticket did not have any answer (almost a month old.. ) I am not sure it will be useful...

PS: I also would like to note that (ironically ?!) in PBI Desktop the behavior is reversed (on resize, I get the wrong data!).

One last note: with the new update of PBI Desktop, the offline behavior matches the online one.

Meanwhile, the related issue has been accepted.

Thank you for you support,
