Windows 10: WPF DataGrid very poor scroll performance

Hello,I need to implement a spreadsheet like control in my WPF app, and all my attempts at using the WPF DataGrid have resulted in very very poor scrolling it is worst in horizontal than vertical. I have tried:fixed row and column height/widthsimplified cell stylesvirtualizationdisabling automationpeerThe WinForms DataGridView, however, it is very slow at selecting cells, since rows become unbound and all that, so it is also not usable for my purposeand I still get very clumsy scrolling even for a 100x100 grid. I think this is not really usable as it is.How can I get a fluent spreadsheet in

:)

 

WPF Datagrid disappearing cells after latest window's update

First im no longer sure where is the best place to post such bug/questions with connect retired....

The tests, for now, point to a flaw in the WPF datagrid that cause the content of some cells to disappear (becomes blank) if the grid has a scrollbar and the view is scrolled up and down several times. This flaw only seems to appear in Windows 10 feature
update, Version 1903 (i.e., Build 18362), released this past May. Also, I was able to reproduce this misbehavior with older version of our software which never had this issue.

For the tests that I did just now, the misbehavior does not appear on Windows 8.1 and Windows 10 (Versions 1703, 1803, and 1809).

I may be wrong but it seems that this problem occurs only on cells using a DatagridTemplateColumn.

 

Poor Performance..

Ehh, well that didn't work...everything went well during the flash nothing went wrong, but no changes... Still low framerates...and poor performance...and other suggestions anybody?

 

Enable visual styles in WPF application

EUREKA!

Steps:
1) I made a Windows form (HostWPF namespace, Form1 is the form).
2) I added a reference => System.Windows.Forms.Integration which contains classes that enable interoperation between the Windows Forms and WPF technologies. When you use System.Windows.Forms.Integration classes, you can host Windows Forms controls on WPF pages, and WPF elements in Windows Forms-based applications.
3) Then added a control (damn Vi$ual $tudio 2010 does not allow to add a WPF window) but after adding I edited the XMAL code in the way I want *Wink
4) The next steps are simple. Download the first attachment. But => see the photo.
It crashes!!!!!
5) Finally???
We must use System.Windows.Forms.Application.Exit(); command because the WPF window behaves like a classical Windows Form.
Download the second attachment. Note that the Windows form's name is Initial.
Enjoy!
