I have a simple NumericUpDown control showing milliseconds. I use a 'ms' custom unit to show alongside the number.
It looks good but as soon as hit the + or - key, the 'ms' disappears and I have just a number. This is because hitting +/- gives keyboard focus to the edit box -- activates the cursor in there and all that. Once I click somewhere else focus leaves the edit box, the 'ms' re-appears.
Is there a property or some simple way that would let me prevent this behavior? I want +/- to just change the number without grabbing the keyboard focus.
Note that I do still want the number to be user-editable if they actually go to the trouble of clicking directly in the edit box itself. I just want to stop +/- from doing that for me.
<tk:RadNumericUpDown Width="150" Height="50"
Value="{Binding Exposure}"
IsInteger="True"
CustomUnit="ms"/>It looks good but as soon as hit the + or - key, the 'ms' disappears and I have just a number. This is because hitting +/- gives keyboard focus to the edit box -- activates the cursor in there and all that. Once I click somewhere else focus leaves the edit box, the 'ms' re-appears.

Hi Joe,
You can create a custom control and override the FormatEdit method. Here is an example:
public class MyMupDown : RadNumericUpDown
{
public override string FormatEdit()
{
var value = base.FormatEdit();
return value + "ms";
}
}
I hope this helps. Should you have any other questions do not hesitate to ask.
Regards,

Hi Dimitar,
Thank you for the answer. Unfortunately this does not quite get me there.
While this fix does prevent +/- from putting focus in the edit box, unfortunately it also prevents me from ever using the edit box again. Now even if I click in there and try to type a number, the keys are ignored.

Hi Joe,
It works on my side. I have attached my project and a small video that shows this.
Let me know what I am missing.
