Skip validation of UltraNumericControl

Hi, I'm using the UltraNumericControl to let the user chose integer values from 1 to 100 (set as min and maxvalue). Whenever the user enters "0" as value the ValidationError-event is fired and I reset the value to 1 (using .value, because resetvalue sets the value back to "0"and resettext sets it to ""). Problem #1: It takes up to 1 second until the control shows the value I set in the ValidationError-event. Why? Problem #2: When the user enters an invalid value he should still be able to click the cancel button of the form. But it seems that the ValidationError-Event disabled all other events, I don't even get the click event af a button when the value is invalid. Another small issue happens when opening the form for the first time. In the load form shown event I focus the Control and use SelectAll to select the text in the control.This seems to take some time, because my form is opening really slow. I guess this will happen when the control has to change to the edit mode, but is there a workaround to increase the speed? Thanks in advance, Stefan PS: Seems the forum just removes my line feeds...

Thanks again, that is a good start. The problem is to cancel the OK button when the value is invalid. Actually the UltraNumericEditor changes the value from 0 back to 1, just before the OK button triggers. So my form always reports 1 to its parent form when the user entered any invalid value and clicked OK.

Edit: Found another issue: When clicking ok the Event will be fired, but not when pressing enter to confirm the ok button...

It may be a bit of a workaround but you can set the e.RetainFocus property to false in the ValidationError event handler and this will allow the Cancel button to operate. Of course, this means any other control will be able to work too.

Hi Andy,

thank you for your answer. It seems that the value of the CausesValidation property has no effect to the Control. As soon as I enter a number out of the valid range, the control still blocks the cancel button. The only way to close the form is using the close button (X)..

PS: Wuhuuu, at least my line feeds in my posts seem to work when using the IE7 instead of Google Chrome

Hopefully I can help with Problem #2, the Cancel button. Just set the CausesValidation property of the button to false.
