DrawingTools how to add metadata = {customId : int(unique id)} at drawingEnded

Question

Hello

I am using bing map v8, Web Controls DrawingTools

I would like to add metadata to the shape when client create it at drawingEnded

When I load a recorded shape from DB , I am able to add this info polygon.metadata = {customID:int(id from DB)}

just before drawingManager.add(polygon);

I need to add this info to the shapes for better identification and management and i would prefer to avoid to record it in DB adding this customId then clear() and reload() my shapes from DB

Thanks for your light

Answer 1

I've put together a code sample that shows how to do this. You can try it out here: http://bingmapsv8samples.azurewebsites.net/#DrawingTools_ShapeMetadata

You can find the source code here: https://github.com/Microsoft/BingMapsV8CodeSamples/blob/master/Samples/Drawing%20Tools/DrawingTools_ShapeMetadata.html

hello Thanks
but this is not exactly what I need , I want to put metadata when i create polygon with the tools bar

at least a time stamp as default, in your sample the shape is created then you add it in drawingtools

but when you create a new one there is no metadata...

Is there any possibility or i have to use the DrawingTools_CustomToolbar.html to achive it ?

function drawPolygon() {

if (setMode('polygon')){

//Create a new polygon.

tools.create(Microsoft.Maps.DrawingTools.ShapeType.polygon, function (s) { s.metadata = { customId : timestamp };

s.setOptions(style);

currentShape = s;

});

}

}

thanks

I think i found solution

I Cut Paste the shapes and in the middle I add the metadata

I do not know if this solution is the best one but working

var shapes = drawingManager.getPrimitives();
            
        if (shapes && shapes.length > 0) {
            alert('Retrieved ' + shapes.length + ' from the drawing manager.');
            
            for(i=0; i<shapes.length; i++ )
            {
                 
                if (!shapes[i].metadata)
                {
                    
                    alert(shapes[i].getRings()+' ---  no data');

var customid = Number(new Date());

                     copyShape = new Microsoft.Maps.Polygon(shapes[i].getRings());

                    copyShape.metadata = {
                    customID: customid
                };
                drawingManager.remove(shapes[i]);
                drawingManager.add(copyShape);

       
                }
                else
                {
                    alert(shapes[i].getRings()+' --- '+shapes[i].metadata.customID);
                }
                
            }
