RaiseCustomEvent

How do I raise a custom event within a custom visual which will be picked up by the reportContainer. This seems to happen by "magic" when using the categorical dataViewMappings however when using table.

 

    "dataViewMappings": [
        {
        "table": {
                "rows": {
					"select": [{
                    "for": { "in": "Values" }
					}],
                    "dataReductionAlgorithm": { "top": { "count": 30000000 } }
                },
                "rowCount": { "preferred": { "min": 1 } }
            }
        }
    ]

no event is fired.

 

I have tried using the table template but this does not seem work. I cannot get it to display a two dimensional array. E.g. a spreadsheet.

 

Thanks,

@bibble235,

 

Based on my experience, you can use addEventListener() method. As for the layout, just play with HTML and CSS.

Re: RaiseCustomEvent

Managed to raise a custom event but this is still not picked up by the report.on function within the iframe. I have tried the table template which uses the categorical DataViewMappings but this does not show the data in the manner I need.

 

All I want is to click on a row and have the report.on function be notified.

Not sure why this seems to be so hard but is the simplist way of showing data.

 

                report.on('dataSelected', event => {
                    debugger;
                    return;
                });

Next attempt consisted of in the click

 

		let myEventData = [];
		myEventData[0] = this.innerHTML;
		let myHTMLElement = this;
		raiseCustomEvent(myHTMLElement,"dataSelected",myEventData);
		console.log(this.innerHTML);

Wondering if I should try WindowPostMessageProxy. I guess it is my lack of knowledge of the product but this seems really hard to do something which looks quite simple. Thanks for taking the time to reply.

@bibble235,

 

There are a few limitations to using Power BI JavaScript API as well, just leave a comment on GitHub.
