I have a table called DriverInductions, which is a custom many to many. That is, it has two lookup columns, one for Driver and one for Induction, creating a custom many to many, with additional columns (which Dataverse doesn't allow in its many to many relationships).
It has an "Active DriverInductions" view, which has a PowerFx "+ Add Existing Induction" command button. If the view is placed in the Induction Main Form, that button works as expected but the view can also be placed in the Driver Main Form, where the button doesn't make sense, instead it needs to show a "+ Add Existing Driver" button and hide the Add Induction button.
Is there a way to write a formula that sets the command visibility based on the parent?
This question mentions making a reference to the parent record but I am not sure if I can use this for what I need.
With(
{
PARENT_RECORD: First(Self.Selected.AllItems).<YOUR_LOOKUP_COLUMN_TO_PARENT_RECORD>
},
CountRows(Filter('Questions','Questionnaire'.'Questionnaire'=PARENT_RECORD.<YOUR_PARENT_RECORD_IDENTIFIER> And 'Status Reason'='Status Reason (Questions)'.Unanswered))=0
)
Bonus question. How does one debug a PowerFx command? I see that you can put a breakpoint in Javascript on the line for the formula but debugging a minified JS script is rather difficult to say the least.
Correct - the commands are not view centric so you can't target a command bar button to only appear in certain views with OOB view criteria. I have not tried querying the current view - it would have to be in javascript but I imagine it would be some DOM traversing on the View selector or the grid fetchXML. It would be prone to breaking if MS chooses to change the DOM layout.
I was trying to avoid RibbonWorkbench which is so slow to publish, while the commands publish relatively quickly.
It seems like the commands are table centric and not view centric? Is there any way to query the name of the view the button is on? If so, I could create two views, with different names and hide a button based on the view, rather than the parent.
That's a handy tip to use notify. Thx
Good question… the post you’re referring to has a Main form button whereas you have a subgrid button, so the context is very different. With PowerFX… I don’t think this is possible.
I believe this is possible with a JavaScript button, you should be able to reference the ‘Parent.Xrm’ context and get the entity type to complete your show/hide. I would def recommend using the RibbonWorkbench tool if you go this route.
Edit: Debugging PowerFX commands - the best way I’ve come up with is to break things down in discrete (with) actions, and use Notify() to inform you of the state of variables along the way. For example -
With({
var1 : [small staged query/data element],
var2 : [same as above]
},
Notify(“var1: ” & var1);
Notify(“var2:” & var2);
[your action here]
)
you would also wrap your action around some error handling so it can notify you if your Patch command or other command failed and display the error message.
