I have looked through the documentation, browsed the widgets and searched here on GIS SE. I can't find any information regarding being able to override the default (published) symbology of a ArcGIS Server feature service.

Is this a feature that is available and I am overlooking it?

For now I am going to republish my service with new symbols, but like the idea of being able to alter it in the application to create different presentations of the same map.

I tried to adjust for yourself.

You need to edit the file Controller.js. In section initLayer you must add the following at the end:

    if (layer.options.renderer_url != undefined && layer.options.renderer_url != '') {
        require([layer.options.renderer_url], function () { l.setRenderer(renderer); })
    };

In Viewer.js you must to each operationallayer add to section options parameter renderer_url that contains the path to file where you define renderer.

    operationalLayers: [{
        type: 'feature',
        url: 'http://.../MapServer/0',
        title: 'Name',
        options: {
            id: 'yourID',
            renderer_url: 'renderers/myRenderer.js',
            opacity: 1.0,
            visible: false,
            outFields: ['*'],
            mode: 0,
            refreshInterval: 0.08333 //if you want refresh layer
        },
        ...

Finally you create for each layer different file with renderer (for example myRenderer.js in folder renderers in root of CMV app):

    var renderer = new esri.renderer.UniqueValueRenderer(new esri.symbol.PictureMarkerSymbol('images/image.png', 30, 30), attributeField as String);

    //add symbol for each possible value
    renderer.addValue({
            value: "value1",
            symbol: new esri.symbol.PictureMarkerSymbol('images/image1.png', 30, 30),
            label: "label1"
    });
    renderer.addValue({
            value: "value2",
            symbol: new esri.symbol.PictureMarkerSymbol('images/image2.png', 30, 30),
            label: "label2"
    });
    ...

For me it works.

  • Thank you for your help. I am trying to test out your solution in my map but I think I need just a little more information to get it working. I am looking at my Controller.js and am unsure where I should exactly paste the "if (layer.options.renderer_url..." code. My initLayer section has some pre-existing code, a function that takes a, b as parameters. I have tried pasting your code into that function in various places but all I am doing is crashing the application. Is it possible for you to paste your entire working initLayer section for me to take a look at? – gisloc Apr 28 '15 at 21:16
