BidirectionalStackPanel "Bug"?

Aug 19, 2016 at 7:30 AM
I have a WPF-Application. On one Page i have a DataGrid placed. The datasource have much entries (>10.000). If will open the page then it hangs. After some minutes no responding the break up.

Now I "disable" the lines 280-283 in the BidirectionalStackPanel.cs. After this change the application is working again.

It that a bug or have I do something wrong?

PS: I will send you a mail with german explanation. It´s easier for me to show you, what I mean
