You have to declare in th attributes of the list swipeToDelete: true to allow the list to delete items , but add this preventDeleteProperty:'noDelete' also if you want the list to be able to determine which items can be deleted or not.
so for example:
var attributes ={itemTemplate: 'food-filter-list/entry',swipeToDelete: true,preventDeleteProperty:'noDelete',reorderable: false,filterFunction: this.FilterList.bind(this),formatters:{Food_Item:this.formatName.bind(this),Points:this.formatNumber.bind(this)},delay: 500, //1 second delay before filter string is useddisabledProperty: 'disabled'};
this.model = {disabled: false};
this.controller.setupWidget('filterlistID', attributes, this.model);
this.filterlist = this.controller.get('filterlistID');
the default implementation allows delete of all the items.
Now if you want to allow an item not to be deleted :
entry = {Food_Item: $L(row.Portion + ConnectionWord + row.Food_Item), Points: row.Points,ItemObj:row,'noDelete':true};
this.FoodList[i] = entry;
this way you can dynamically determine which item can be deleted or not
cool , no?
