I have a grid with 'x' amount of rows. Using the built in filter functions I'm filtering and ending up with 'y' amount of rows. How is it possible to get the collection of visible rows after filtering? ('y')

Hi John,

Working with visible item is not the preferred approach. It is best to work with the data itself. For example, you can get all items that remain after filtering from the Items property of the grid.

Sorry for being unclear with what I want, but I'm trying to access the data available after filtering as you're saying. However, I haven't found a property where I can access that. 
I'm trying to access the information in XAML.

Hello John,

You may use the Items collection of the grid. It will return the number of items being filtered as well.

Hello John,

May you provide a bit more details about the exact scenario you want to accomplish ? What do you want to use the Items collection in xaml for ?
 

All the best,

Because I wanna bind it to a property and base a graph on the filtered rows. 

Expample: 
I have 10 rows, and I want to show a graph based on all 10 rows. 
I filter on name etc, and ends up with 4 rows, the graph should be reflecting what's available in the grid at the moment.

Hi,

 You can bind the chart to the grid Items collection directly.

The Graph will be in another control. Therefore I wanna bind it to a property so that I can go thru parentViewModel and so on, and get the values from that.
