Shared Complex Data Source

[Nikita]

I'd like to use a shared DataSource control that encapsulates a complex data object with several enumerable properties. I'd like to bind each property to a separate drop down list. Is it possible to define one data source but several schemas, one for each drop down list? Values of each drop down list affect the state of the data object and it take 1 server operation to obtain the data, that is why I want to use a single shared DataSource.

Hello Nikita,

The DataSource will pass to the widgets the entire data that is available and I have to say that it is not possible to set specific inner collection to specific widgets. However, if you want to make only one request for the data, you could use one DataSource for getting it and within the "RequestEnd" event, get the data and populate the DataSources of each widget, using their "data" method:

• https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/events/requestend 
• https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/methods/data

Let us know if other questions on this matter arise.
