We have an issue with the RadNumericInput control. It does not display the error template (border or tooltip) when an error is raised until you roll over the control. The error tooltip also appears blank. How can we resolve this issue?

Hi Paul,

Are you testing your solution with our latest release? If yes, can you give us more information about the validation approach(trowing ValidationExceptions, using RegEx, DataAnnotations or IDataErrorInfo) you've implemented? That will help us to better understand the issue and advice you how to get over it.

We are not using the latest version, we are currently using version v.2011.2.712.1040. We have an object that implements INotifyDataErrorInfo and is bound to the RadNumericInput control like so: Value="{Binding Path=Quantity, Mode=TwoWay, ValidatesOnDataErrors=True}". To raise an error notification we simply call SetError("Quantity", "Required field") which calls function:

Public Event ErrorsChanged As EventHandler(Of DataErrorsChangedEventArgs) Implements INotifyDataErrorInfo.ErrorsChanged

Protected Sub SetError(ByVal propertyName As String, ByVal propertyError As String)
 
    ' Add the list collection for the specified property.
    _errors.Add(propertyName, New List(Of String) From {propertyError})
 
    ' Raise the error-notification event.
    RaiseEvent ErrorsChanged(Me, New DataErrorsChangedEventArgs(propertyName))
 
End Sub


This works for all other controls.
