Handle Client-Side Events of DevExpress ASP.NET controls in XAF

Hello Anatol,
thank you very much for your quick reply. It took me a bit further, but unfortunately I´m still having a hard time trying to get behind all this, so thank´s in advance for your patience!
I have attached a little demo XAF project to show what I would like to do. It contains a XAF DashboardView with a custom ViewItem. This item contains one control: an ASPxDashboardViewer with a GridDashboardItem. Drilling is enabled for the Grid. I´m using the viewer´s ClientSideEvents.ItemClick, according to your advice, as well as DrillDownPerformed and DrillUpPerformed. The ClientSideEvents.js file handles those events. I implemented a notification that pops up when a row in the grid is clicked at maximum drill level. It´s working fine so far.
Now, I would like to process information about which item in the grid was clicked. I don´t want to do it in javascript, I would like to do it in C#, since I want to load data from the database, depending on which item was clicked, and then automatically pop up another XAF DashboardView. There is a "Pop up" action that shows that view (it´s empty right now). That view is supposed to show the data loaded from the database, depending on what item was clicked.
So, basically, I want to catch client events and send their sender and args back to the server for processing. Is there a way to do that?
Thank you,
 Andreas

You can show an XAF View from a client-side script by raising an XAF callback. Please refer to the How to implement the drill-down functionality in Web PivotGrid (ASPxPivotGrid) example, where a similar functionality is implemented.
