FeatureTable - Get Selected Rows

Ranga_Tolapi

How to get the list of selected rows from Feature Table without using the "selection-change" event of FeatureTable? Is there any straight method or way to get the selected rows?

Ranga,

Everytime the table's 'selection-change' event is fired it provides a list of rows added or removed from the selection.  So after you set up the FeatureTable, set up a watch on that event such as:

// Get the FeatureLayer's layerView and listen for the table's selection-change event
// Here I'm maintaining a list of features for use elsewhere
let lstFeatures = [];
aFTable.on("selection-change", function (changes) {
    var idxItem = 1;
    // If the selection is removed, remove the feature from the array
    changes.removed.forEach(function (item) {
        const data = lstFeatures.find(function (data) {
            return data.feature === item.feature;
        });
        if (data) {                    
            lstFeatures.splice(lstFeatures.indexOf(data), 1);
        }
    });

    // If the selection is added, push all added selections to array
    changes.added.forEach(function (item) {
        const feature = item.feature;
        lstFeatures.push({
            feature: feature
        });
    });
    zoomToSelectedFeature(aLayer, lstFeatures, aView);
});
