Hi,
What is the most efficient way to update the map layer datasource? For this map I use a url I'd like updated (because a get parameter changes).
I read this: http://d585tldpucybw.cloudfront.net/forums/change-marker-layer%27s-data-source
But it's outdated, currently there is no more _initDataSource() and the setDataSource() did find its way to the layer object but I can't get it to work:
don't find an example for it.
also, I tried:
var layer = $("#selectionMap").data("kendoMap").layers[0];layer.dataSource.transport ={read:$scope.baseUrl+"/MapStatistics"+"?countryvar="+$scope.ui.subSelections.countryVar};layer.reset();Also tried this:
layer.setDataSource({type: "geojson",transport: {read:$scope.baseUrl+"/MapStatistics"+"?countryvar="+$scope.ui.subSelections.countryVar}})
Error: this.dataSource.unbind is not a function
So my question: Is there an efficient way to do this so the map is reloaded on layer url update?
thanks,
Arno

For whomever would have the same issue, the following worked for me.
Change the layer as an option
var map = $("#selectionMap").data("kendoMap")var layer = map.layers[0];map.setOptions({layers:[{type: "shape",dataSource: {type: "geojson",transport: {read:$scope.PythonbaseUrl+"/MapStatistics"+"?countryvar="+$scope.ui.subSelections.countryVar}} }]})Then reinitialize the layers
map._initLayers()
Thanks for sharing your findings with the community.
The layer setDataSource would be our recommendation, but I see that it has some issues we need to address.
First, it's not part of the documentation (yikes!). Second, it does require a live DataSource instance:
var dataSource = new kendo.data.DataSource({type: "geojson", ...});
layer.setDataSource(dataSource)
Apologies for the caused inconvenience.

Hello,
Can you post the location of the documentation? I am trying to update marker DataSource from button click event.
Thanks, K
The Kendo UI Map MarkerLayer setDataSource() method is documented at:
https://docs.telerik.com/kendo-ui/api/javascript/dataviz/map/marker-layer/methods/setdatasource
Let me know if you need further assistance.
Kind Regards,
