In all current examples on RadNumericTextBox with spinbuttons I see InvalidStyleDuration="100". Without this setting, my control with spinbuttons doesn't format properly. The help doesn't say anything.
What is the meaning of this property, how and when is it supposed to be used?
The InvalidStyleDuration property for RadInput controls is used to determine how long the control will display its invalid style when incorrect data
is entered. I guess you would have missed out on the following help document where this is mentioned, take a look at it: Common Properties
This does answer but why not to put this info in the Help? There are many empty topics in the Help, it is obviously not up to otherwise high telerik standards.
And looks like this property has nothing to do with my formatting problem. I may open a support ticket for this.
