I'm using the Datasource object to retrieve data from a remote (JSON) datasource which I would then like to filter client-side without doing any round-trips back to the server. I get the results fine but I'm unable to clear and reapply filters, my code is:

dsReport.fetch().then(function(){

    
    var view = dsReport.view();
    
    dsReport.filter({field:"Occupation", operator: "equals", value:"DEVELOPER"})
    
    console.log(view[0].NumberOfStaff); //Outputs 13 which is correct
       
    dsReport.filter({}); //Remove the previous filter??
    
    dsReport.filter({field:"Occupation", operator: "equals", value:"MANAGER"})
    
    console.log(view[0].NumberOfStaff); //Outputs 13, should be 22, assuming new filter isn't being considered
    
})

Hi Serdar,

The reason for this behaviour is because the view variable is holding a reference to the Kendo UI DataSource view at an earlier stage. To get the updated view, another call to the data source view() method should be made after the filter is applied or removed. 

For your convenience, a simple demo is available at:

Should you need further help, please feel free to ask.

Kind Regards,
