Hello. I'm trying to implement virtual scrolling in my ComboBox. I'm using OData for datasource.
I've tried to use this example (https://demos.telerik.com/kendo-ui/combobox/virtualization) however i'm stuck. I don't know how to implement a Value Mapper in my Web API.
In this example it's easy to do, because tere are no any filters/ordering in the DataSource request. But in my canse i'm using the same OData method for different DataSources, but with differend Filters and Ordering. So, how can i get the index if some value which is not existing in the initial DataSource data, if i don't know which filter/ordering was used for a datasource? Because for different filters/ordering the index of this value will be different.
