NumericUpDown has a ValueChanged event, which is raised when the
value is changed. Based on the changed values, we can detect whether up or down
button is pressed. We have prepared a sample based on your requirement and
attached the sample for your reference.
Could you please check the sample and let us know whether it meet
your requirement or else please provide some more information regarding your
I have the same question and more generally, I would like to know the source that is triggering the 'ValueChanged' event...
I think, unfortunately, there are other sources that can trigger value changed event...
In my case a 'Virtualization' DataGrid re-uses a cell and ValueChanged is triggered for the new cell...
How can we determine the source of the ValueChanged event for a NumericUpDown ( +/- buttons, text content value, UI update, value binding) ??
Thanks in advance,

Thank you for contacting Syncfusion support.
In our SfNumericUpDown control, the source of the ValueChanged event can be the control itself. You can determine it by observing sender of the ValueChanged event which returns the source of it. Please let us know if we misunderstood your query.
