ListBox作为WPF中的数字UpDown控件

Question

One of the disadventage I found in WPF is it doesnot have a Numeric UpDown control. So I make a listbox with height as 25 so that it will display only one item at a time and the vertical scroll feels like a UpDown controls. My problem is when I use the scroll to change the value, I can't get the current value shown in listbox. Can any idea to get the value shown in listbox without selecting it?

Answer 1

The Extented WPF Toolkit has one: NumericUpDown

Answer 2

尽管没有标准的WPF NumericUpDown，但是您可以尝试使用带有主题和UI自动化支持示例的NumericUpDown自定义控件 。

Answer 3

well since you are using WPF, you can change the template of your ListBoxItem and change it's look to nothing when the item is selected ( i mean remove the trigger ), that's all.
I hope it's helpful, unless you need other things than this.

Answer 4

You can also attach a ScrollBar.Scroll event. This fires when you scroll. Maybe you can then change the SelectedIndex manually or set the focus?
