requestEnd fires only once?

[Kenny]

My Data Source is set up to read JSON from my server for a Grid with scrollable.virtual = true. 

I would like to access the data being returned from the server each time the Data Source makes a request and gets more data as the Grid is being scrolled. I think requestEnd is the event I should be using for this. 

However, the requestEnd event seems to fires only once the first time the Grid loads. When the Grid is scrolled down, subsequent requests are made to the server, data is returned and displayed however requestEnd is not fired again. Is this expected?

Hello Kenny,

Indeed, the requestEnd and requestStart events are not raised during remote virtualization, with current version of KendoUI. However, we managed to address this and the fix will be included in the next internal build. Meanwhile, as a temporary workaround you may consider overriding the schema's parse function and handle the raw response there.

Hi Rosen, 

Thanks for the response. This was so close to what I needed but then I realized I actually need the response from requestEnd and not just the raw server response. More specifically I need the UIDs for the objects which aren't available at this point. 

I will think about it a bit more, I may need to use a RowTemplate for my grid at which point I think I can inject my own IDs for referencing the rows and then I wouldn't need the UIDs any more. For now I do have a work around using the Data Source change method, it's not ideal but it will work for now.

Hi Kenny,

The requestEnd does not provide the processed data, as it is raised before data is processed by the DataSource. If you need access to the processed data you should the change event instead.
