I had a similar issue where I needed to limit a field to only numeric and no more than 32 characters in length, When I tried this:

<Setter Property="Mask" Value="{}{char:32:0-9}" />

I received this error if I entered 10 characters or more when . 

When I changed it to this:

<Setter Property="Mask" Value="{}&gt;{char:32:0-9}" />

It worked correctly. Do you know why the first one gives me an error but the second one works?

Thanks,
Jeff

Hello,

yes, it did.

Hello,

Thank you for your post. I have been looking into it and I can suggest you add the following Setter to your Style:

<Setter Property="ValueConstraint">
    <Setter.Value>
        <igEditors:ValueConstraint MinLength="2"/>
    </Setter.Value>
</Setter>

Hope this helps you.

this post looks like the closest one to the problem I am having setting the minimum length:

in my UnboundField, I am setting a <Style> of type XamMaskedEditor of infragistics, like this:

<igDP:UnboundField.Settings>
                                    <igDP:FieldSettings EditorType="{x:Type igEditors:XamMaskedEditor}" >
                                        <igDP:FieldSettings.EditorStyle>
                                            <Style TargetType="{x:Type igEditors:XamMaskedEditor}" >
                                                <Setter Property="Mask" Value="{}{char:50:0-9a-zA-Z _}"/>
...
                                            </Style>
                                        </igDP:FieldSettings.EditorStyle>
                                    </igDP:FieldSettings>
                                </igDP:UnboundField.Settings>

as you can see, the maximum length of the field is 50 characters, but I cannot set the minimum length that is 2.

I would like to use the ValueConstraint property, but don't know how.

could you please, advise?

thanks,
