Hello, Ekaterina.
Thanks for reply.
I used this but it's not solving my requirment. I need to set only length of characters and there is no any restrictions on entering characters. Above mask creates restriction on entering characters. Please guide me on this.

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,

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.

yes, it did.

thanks.

Hello,

Thank you for your feedback. I am glad that you resolved your issue and I believe that other community members may benefit from this as well.

Thanks again.

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
