Custom Visual Filtering

alanwales — Thu, 19 Nov 2015 20:49:14 GMT

I have created a custom visual based on a table of data e.g.

Test Id | Name

1 | Task 1

1 | Task 2

2 | Task 1

2 | Task 2

However when I filter in the report view e.g. Test Id = 1 I cannot find a way to get my code to adapt. It always shows the full list.

my code looks something like this (called from update method)

public static converter(dataView: DataView😞 TestRunViewModel {

var table = dataView.table;

for (var t = 0; t < table.rows.length; t++) {

var cell = table.rows[t];

// table rows are not filtered

}

Anyone have any knowledge of how the custom visuals can be filtered in ts code...?

I managed to find the issue, the child nodes had to be cleared on update e.g.

private elementRoot: HTMLElement;

        public init(options: VisualInitOptions): void {
   this.elementRoot = options.element.get(0);
        }

public update(options: VisualUpdateOptions) {

   while (this.elementRoot.firstChild) {
    this.elementRoot.removeChild(this.elementRoot.firstChild);
   }

... etc

}

Adding calls to console.info helped to track down that the data update was not the issue
