Validation Tooltip just showing standard message

[Heiko]

Hi,

I'm using a RadComboBox (v2010.2.812.1040) where a user can select the country. The property in the underlining looks like:

Public Property LandId() As Integer

        Get

            Return _LandId

        End Get

        Set(ByVal value As Integer)

            If value = 0 Then

                Throw New Exception("Bitte Land angeben!")

            End If

            If value <> _LandId Then

                _LandId = value

                NotifyPropertyChanged("LandId")

            End If

        End Set

    End Property

But in the Radcombo a Standard-Error text is show. How can i force the control to show MY error text...?

Thanks,
Neils

Hi Neils,

I tested the issue and I was able to show my custom message using this:

If value <> Me.selectedIndex Then
    If value = -1 Then
        Throw New Exception("Custom exception!!")
    Else
        Me.selectedIndex = value
        Me.OnPropertyChanged("SelectedIndex")
    End If
End If

I was using the SelectedIndex though. Could you please send me a simple project where this issue could be observed. This will help greatly in investigating what the problem might be.

Best wishes,
