Bing Maps - Invoke Click Event on PushPin

Question

I have the following bing map: https://www.bob-elliot.co.uk/locateV2.php

When a shop is selected in the left-hand list the map auto centers on that pushpin, what i need to do now is invoke the click() handle of that pin (or show the relevant InfoBox).

Problem is, i'm pushing the pins into a Microsoft.Maps.EntityCollection(); called dataLayer so i cant call map.entities.get() directly - or rather - if i try calling it this way get() does not return anything.

Note the zoomMap() function at the bottom of this snippet, i have commented out the lines in question.

How can i invoke the click event?

var map = null;
var dataLayer = null;
var infoboxLayer = null;

function loadMap() {
    //#### Prep default location
    var defaultLocation = new Microsoft.Maps.Location(53.6880, -2.6646);

    //#### Prep Map Options
    var mapOptions = {
        credentials: 'KEY_REMOVED',
        center: defaultLocation,
        mapTypeId: Microsoft.Maps.MapTypeId.road,
        zoom: 7,
        enableClickableLogo: false,
        enableSearchLogo: false
    }

    //#### Initialise the primary map control
    map = new Microsoft.Maps.Map(document.getElementById('BobElliotMap'), mapOptions);

    //#### Add data layer
    dataLayer = new Microsoft.Maps.EntityCollection();
    map.entities.push(dataLayer);

    //#### Add infobox layer
    infoboxLayer = new Microsoft.Maps.EntityCollection();
    map.entities.push(infoboxLayer);

    //#### Prep InfoBox & add to infobox layer
    var infoboxOptions = {
        width: 300,
        height: 200,
        visible: false,
        offset: new Microsoft.Maps.Point(0, 20)
    };

    infobox = new Microsoft.Maps.Infobox(new Microsoft.Maps.Location(0, 0), infoboxOptions);
    infoboxLayer.push(infobox);

    //#### Add Data to the map
    DrawPins();
}

function displayInfobox(e) {
    if (e.targetType == "pushpin") {
        infobox.setOptions({
            title: e.target.Title,
            description: e.target.Description,
            visible: true,
            offset: new Microsoft.Maps.Point(0, 25)
        });
        infobox.setLocation(e.target.getLocation());

        //#### A buffer limit to use to specify the infobox must be away from the edges of the map.
        var buffer = 30;
        var infoboxOffset = infobox.getOffset();
        var infoboxAnchor = infobox.getAnchor();
        var infoboxLocation = map.tryLocationToPixel(e.target.getLocation(), Microsoft.Maps.PixelReference.control);
        var dx = infoboxLocation.x + infoboxOffset.x - infoboxAnchor.x;
        var dy = infoboxLocation.y - 25 - infoboxAnchor.y;

        if (dy < buffer) { //Infobox overlaps with top of map.
            //#### Offset in opposite direction.
            dy *= -1;
            //#### add buffer from the top edge of the map.
            dy += buffer;
        } else {
            //#### If dy is greater than zero than it does not overlap.
            dy = 0;
        }

        if (dx < buffer) { //Check to see if overlapping with left side of map.
            //#### Offset in opposite direction.
            dx *= -1;
            //#### add a buffer from the left edge of the map.
            dx += buffer;
        } else { //Check to see if overlapping with right side of map.
            dx = map.getWidth() - infoboxLocation.x + infoboxAnchor.x - infobox.getWidth();
            //#### If dx is greater than zero then it does not overlap.
            if (dx > buffer) {
                dx = 0;
            } else {
                //#### add a buffer from the right edge of the map.
                dx -= buffer;
            }
        }

        //#### Adjust the map so infobox is in view
        if (dx != 0 || dy != 0) {
            map.setView({
                centerOffset: new Microsoft.Maps.Point(dx, dy),
                center: map.getCenter()
            });
        }
    }
}

Solution

Looks like for some reason e.target is not coming in displayInfobox function.

I have but modified your code a little bit at 2, 3 places to get something close to your intended point. Please check it below:

var map = null;    
var dataLayer = null;    
var infoboxLayer = null;

function loadMap() {

    //Prep default location    
    var defaultLocation = new Microsoft.Maps.Location(53.6880, -2.6646);

    //Prep Map Options    
    var mapOptions = {
        //credentials: 'KEY_REMOVED',
        center: defaultLocation,
        mapTypeId: Microsoft.Maps.MapTypeId.road,
        zoom: 7,
        enableClickableLogo: false,
        enableSearchLogo: false
    }

    //Initialise the primary map control
    map = new Microsoft.Maps.Map(document.getElementById('BobElliotMap'), mapOptions);

    //Add data layer
    dataLayer = new Microsoft.Maps.EntityCollection();
    map.entities.push(dataLayer);

    // Add infobox layer
    infoboxLayer = new Microsoft.Maps.EntityCollection();
    map.entities.push(infoboxLayer);

    //Prep InfoBox & add to infobox layer
    var infoboxOptions = {
        width: 300,
        height: 200,
        visible: false,
        offset: new Microsoft.Maps.Point(0, 20)
    };

    infobox = new Microsoft.Maps.Infobox(new Microsoft.Maps.Location(0, 0), infoboxOptions);

    infoboxLayer.push(infobox);

    //Add Data to the map
    DrawPins();


    setTimeout(function() {
        //Initial zoom for testing zoomMap function
        var pushpin = dataLayer.get(0);
        var indx = dataLayer.indexOf(pushpin);
        zoomMap(indx, pushpin.getLocation().latitude, pushpin.getLocation().longitude);
    },500);

}


function displayInfobox(e) {

    if ( this.target.id && this.target.id.indexOf("pin") != -1 ) {
        alert("click event fired on pushpin");

        infobox.setOptions({
            title: this.target.Title,
            description: this.target.Description,
            visible: true,
            offset: new Microsoft.Maps.Point(0, 25)
        });

        infobox.setLocation(this.target.getLocation());

        //A buffer limit to use to specify the infobox must be away from the edges of the map.

        var buffer = 30;
        var infoboxOffset = infobox.getOffset();
        var infoboxAnchor = infobox.getAnchor();
        var infoboxLocation = map.tryLocationToPixel(this.target.getLocation(), Microsoft.Maps.PixelReference.control);
        var dx = infoboxLocation.x + infoboxOffset.x - infoboxAnchor.x;
        var dy = infoboxLocation.y - 25 - infoboxAnchor.y;

        if (dy < buffer) { //Infobox overlaps with top of map.
            //#### Offset in opposite direction.
            dy *= -1;
            //#### add buffer from the top edge of the map.
            dy += buffer;
        } else {
            //#### If dy is greater than zero than it does not overlap.
            dy = 0;
        }

        if (dx < buffer) { //Check to see if overlapping with left side of map.
            //#### Offset in opposite direction.
            dx *= -1;
            //#### add a buffer from the left edge of the map.
            dx += buffer;
        } else { //Check to see if overlapping with right side of map.
            dx = map.getWidth() - infoboxLocation.x + infoboxAnchor.x - infobox.getWidth();
            //#### If dx is greater than zero then it does not overlap.
            if (dx > buffer) {
                dx = 0;
            } else {
                //#### add a buffer from the right edge of the map.
                dx -= buffer;
            }
        }

        //#### Adjust the map so infobox is in view
        if (dx != 0 || dy != 0) {
            map.setView({
                centerOffset: new Microsoft.Maps.Point(dx, dy),
                center: map.getCenter()
            });
        }
    }
}


function DrawPins() {

    var pin0 = new Microsoft.Maps.Pushpin(new Microsoft.Maps.Location(53.1913, -2.51945));
    pin0.id = "pin_0";
    pin0.Title = "** CYCLONE CYCLES A/C CLOSED";

Sorry for the late accept, i must have got distracted back in November! Your approach works great (making use of the .id attribute) & is live on the link in my question – thanks for the tip!

Usage of "this" in displayInfoBox() made the difference.
