Hello!
I've been working on this problem for days now... and I can't solve it. Here's the thing:
Is there any way to see when a numupdown value has decreased or increased
I am making a program, that, depending on the value of a NumUpDown control, counts the price of an item.
When a tab is entered (OnEnter) the NumUpDown control is activated. It's value is set to 100.
if
(lenght >= 100 && lenght < 110){
price = price + 2;
}
else if(lenght == 100 || lenght <= 99)
{
price = 0;
}
The problem is that price gets increased even if a user pressed key down. Like
100 -> 101 - > 102 -> 103 -> 104 -> 105 the value increases
Now, if a user makes the NumUpDown value go down 105 -> 104 -> 103 it still makes the price increase, because the value is >= 100 && < 110
Is there any way to prevent that

Or maybe I could add a textbox, and 2 buttons. Then limit textbox to numbers only and read only. one button would increase the number and other would do opposite.
Is that possible

Yes, you can add two buttons and textbox, it would be much more simpler logic.
you just have to code click events of buttons.
