NumericUpDown

i need help whit the numericUpDown

I tried many ways but first let me explain the objective of the
control

1 - range from 1 to 100
2 -the person can enter higher value that 100 but it put back to 100
and popup the person
3- when pressing up it goes to closest increment of 25 (25-50-75-100
are possible value)
4- when pressing down it goes to closest increment of 25 (75-50-25-1)

the first thing is that 1 next increment of 25 isnt 25 but 26
ok so i set on the value change is the value happen to be 26 set value
to 25.
by default problem 2 is solved by itself nearly because numeric value
under minimum set back to minimum and value over maximum set to
maximum. the popup i was able with the Keypress check the numeric.text
and test if it was higher than the maximum and i made the popup it
work fine

the problem is. when i manually change value it trigger the
valuechange and the click up or down also trigger it.

if anyone know how i can capture in the valuechange has been triggered
by the up and down button or not i would be able to test all this.

if i put in the value change :
if(numeric.value >0 && numeric.value <25)
{
numeric.value = 25;
}
it work to go up to closest 25 increment but if i type 19 for example
and want 19 it doesnt distinguish if i clicked up to go to 25 or if i
change the value to 19 for him both trigger the code but it work only
for 1.

numeric.Minimum = 1;
numeric.Maximum = 100;
numeric.ReadOnly = true; // disallow typing a value
}

Eq.

The original post wants the ability to type values into the control.

Sorry, I cannot figure this one out either. There is no arrow click event.
Maybe if you can inherit a user control from NumericUpDown, you could figure
out the events to signal a user defined event to handle. That would be what
I would investigate...

the closer solution ive come to so far would be a textbox checking for
numeric value and reating myselft up and down button or a vertical
scrollbar if more look like the up and down button

Nobody should ever use NumericUpDown. The control has major bugs on
handling focus and validation. Inherit from the NumericUpDownBase and
write your own.
