My application has a RadDateTimePicker at the top of most forms; often the forms require some scrolling.  When a user enters the form, the RadDateTimePicker gets focus, and then when he tries to scroll down the form, he instead will inadvertently scroll the date, then (when the month reaches 12, its highest value) the form will scroll.  The user often will not know that he accidently changed a value.

My users never want to scroll the date (they are always surprised when I point out to them that it does scroll), so I want to turn off that functionality.  My first thought was to get the event handler and set Handled to true ... but there is no such property on that event handler.  Then, even though I knew better, I tried to go down the road of removing the existing handlers ... but even Reflection balks at that.

So, is there a way for me to disable the MouseWheel event in the RadDateTimePicker?  Or do you have alternate suggestions?

Thanks!

That did it.  Thanks!

Is this the best solution for the problem how to the scrolling of datetimepicker? MulticolumnCombobox has ScrollOnMouseWheel, why not a similar function for datetimepicker?

Just to add,

using the above workaround, upon scrolling on a datetimepicker set to nulltext, the control will be having a new value.

I think this is the right choice.

dateTimePicker.DateTimePickerElement.TextBoxElement.EnableMouseWheel = false;

Hi Joem,

Thank you for writing.

The EnableMouseWheel property was introduced at the end of 2011, so with any later versions of the controls this is the correct way to handle this type of scenario.

Should you have further questions please do not hesitate to write back.
