TrackBar doesn't apply the TickFrequency when I drag it

Question

Hi,

I have set the TickFrequence on my TrackBar to 1 and when I use the arrow keys it only increases or decreases one, as it should, but when I use the mouse it show decimal values.

I googled it but couldn't find any help. Can someone help me with this?

Note: I'm using WPF

Thanks in advance,

Tomas
