By using Application.DoEvents (not nice but works) I can see how it is building up also when the list is very huge. I just want some similar in WPF. Here is my project: http://www.goldengel.ch/temp/FileContent%20Replacer.zip I already posted...

Essentially I'd like to click on a button...

(e.g 10 per seconds say) - in my case th...

A...

I have all the code in place, but when I update the styling (after obtaining some values from form elements) the datagrid does not update the display of the elements. I h...

Cheers, Berryl I just found this ...

For the most part this works great, and the application window appears immediately after the hotkey is pressed. However, if it has been a long time since the user has activa...
