Filtering ListView dataSource

[Amrutha]

Hi,

 In my application I am populating a ListView using a service call. I am adding a TextBox and a filter button in the navbar of that page. I have filtered the ListView using the following method.

 function filter(){
        var listView = $("#SubFolderList").data("kendoMobileListView");
        listView.dataSource.filter({ field: "ItemName", operator: "contains", value: SearchValue });
        //here i need the count of the items
 } 

I have a clear filter button near to the filter button, I want to clear the filter on pressing the clear button.

Please help me finding a solution with service call

Thanks,
Amrutha.

To remove the filter, simply call the filter() method of the datasource with no arguments - this would remove any existing filters e.g.:

clearTheFilter: function () {
            //Clear Filter
            dataSource.filter({});
        }

Thanks for the answer... It worked. Can you please help me to find the count of data after filtering.

Thanks,
Amrutha

Hi Amrutha,

You can use the view method of the datasource which correspond to the current page, filter, sort and group configuration e.g. dataSource.view().length. If you have paging applied, you can use kendo.data.Query.
