I use the 2015.1.401.40 version of your ASP.NET for AJAX controls.
If it matters, I'm currently binding it to a SQLDataSource.
From what I see, the entire PivotGrid does a PostBack when you:
- click a filter to display the Filter Popup
- expand or collapse a row or column field to show or hide detail
The same with the filter popup... when you click the filter icon, why not just display a div that you could have put in the page when the control was initially bound? Why do a postback to then just display the filters in a popup?
Am I missing something or doing something wrong? Most of you other controls (hierarchical grid or grid with grouping), they are able to hide / show children or grouped rows on the client. Why doesn't the pivot grid?
