I have a XamNumericEditor declared as follow :
<igEditors:XamNumericEditor x:Name="_xamNumericEditorNumberOfObjectToAdd" DockPanel.Dock="Left" ValueType="{x:Type sys:Int32}" Value="{Binding NumberOfObjectToAdd}" Mask="99" PromptChar=" " Width="50" DataMode="Raw" DisplayMode="Raw" SpinIncrement="1" SpinWrap="False" SpinButtonDisplayMode="Always"> <igEditors:XamNumericEditor.ValueConstraint> <igEditors:ValueConstraint Nullable="False" ValidateAsType="Integer32" MaxInclusive="50" MinInclusive="1" /> </igEditors:XamNumericEditor.ValueConstraint></igEditors:XamNumericEditor>
And when I click on it, it throws this exception :

How can I solve it plz ?
PS: How can I add fomatted code on the forum ?
I have created a support case on your behalf (CAS-46927-WH1C8C) and have linked to development issue (33414) for this. You will be notified when this is resolved and the service release is out.
Meanwhile, you can use a numeric mask (like "nn") instead of "99" to go around this.
Hello,
I was able to reproduce this. It seems that the issue is coming from setting the SpinIncrement property as well the Mask. If only one is set at a time, this is not reproducible. I will further test this and will update this thread when I have more information on this.
