Property 'selected' does not exist on type 'RadListView'.

[Anurag]

Hi

Am just trying to upgrade my angular nativescript project to Nativescript 3.0. While executing tns run android I get an error 

Property 'selected' does not exist on type 'RadListView'.

The relevant lines from my code are

public itemSelected(args: ListViewEventData) {

var item = this.dataItems.getItem(args.index);

item.selected = true;

}

Please help.

Hello Anurag,

The error indicates that you are accessing custom property selected on the current item which is not existent
Based on the snippet you are getting the current item by using the index (args.index) to access the data source behind the current item. However, we have no information what this.dataItem.getItem(args.index) is as object structure.

For example, it could be something like:

var item = this.dataItems.getItem(args.index)l

// does item have selected property?
// item = { name: "John", score: 42 }
// or
// item = { name: "John", score: 42, selected: false }

As a side note with nativescript-telerik-ui version 3.0.1 we could use getSelectedItems method as described in this documentation article and as shown in these examples.
