We are going to fix the above issues. Please add a reference to MWLib and then update main window XAML like this:
Originally the “scroll wheel” was used mainly for scrolling, hence its name. In WPF however holding a keyboard modifier down changes the field of application: if one holds the Control key while rotating the wheel text size will increase or decrease in some web browsers; on the other hand an image in an image-editing program will zoom in or out. Other applications scroll horizontally if you hold the Shift key down.
You would have to look into the Drag and Drop event(s) of the form, I think you need to enable OnEnter on the form aswell, its been a while since i've done windows forms programming.

Because the existing wheel change event has no indicator if its about horizontal or vertical. Adding such an indicator like a boolean forces developers to check that. Existing code wouldn't check that, so it breaks.
Kul hem çkırmızııştırayım dedim hemde daha da vüruttireyim dedim. Gördüğüm derste iki listbox kullanılmıştı ve sadece birinden diğerine item atabiliyordunuz. şu demek oluyor ki mazi ittihaz yoktu. Ben ise formuma 8 pare listbox ekledim ve herhangi birinden herhangi birine item taşıyabiliyorsunuz.
Kısaca ben bilet satarken "bilet hile"daki resmi sürükleyip gidermek istediğim koltuğa güruhkleyip bırakacam ve bundan sonrasında haliyle koltukta bundan sonra "boş" bileğil "yoğun" yazacak.Aynı koltuğu bir daha fethetmek istersem bana bir kusur iletiı verecek. Ve biletlerin durumunu eğlenmek muhtevain listbox’a ne olup bittiği yazgılacak.
Kodları açıklamam gerekirse; Buradaki If bloğumuzda denetçi ettiğimiz şey, farenin Textbox üzerine vardığında tamir etmek istediği şeyin ne olduğunu çıkarmak.

If you don't need the complicated stuff but still wants WPF issues fixed, use the following code at the beginning of your XAML entry point:

Focus or mouse capture take precedence over where the mouse pointer is; therefore, if you receive the MouseWheel event from a focused or captured element, the mouse pointer might actually be over another element.
For those eager to get their hands dirty before eventually resuming reading, we’ll begin with a quick-start guide. Then after some background information and an overview of MWLib features, we’ll go through a small tutorial: you will create a WPF application, spotting out-of-box mouse wheel support limitations and using MWLib to fix them.
