I figured it out. I needed to set the Format and not the Mask in the setter.

This doesn't work for me. This concept of styling a value in a cell is difficult to understand. There are

I have this XAML and the data is a double but the formatted value is weird. A negative double value doesn't show up at all, a poitive double value shows up as a really weird value such as $134,940.00;($9,000)

                                        <igDP:Field Name="Col5" Label="BASE YEAR BUDGET">
                                    <igDP:Field.Settings>
                                        <igDP:FieldSettings AllowEdit="False"   
                                                            EditorType="{x:Type igEditors:XamCurrencyEditor}">
                                            <igDP:FieldSettings.EditorStyle>
                                                <Style TargetType="{x:Type igEditors:XamCurrencyEditor}" >
                                                    <Setter Property="Mask" Value="$###,##0.00;($###,##0.00)" />
                                                </Style>
                                            </igDP:FieldSettings.EditorStyle>
                                        </igDP:FieldSettings>
                                    </igDP:Field.Settings>
                                </igDP:Field> 

Strangley, if I use this XAML:

<igDP:Field Name="Col6" Label="FUNDING">
                                    <igDP:Field.Settings>
                                        <igDP:FieldSettings AllowEdit="False"
                                                            EditAsType="{x:Type sys:Decimal}"/>
                                    </igDP:Field.Settings>
                                </igDP:Field>

The field displays almost as I want it. It shows as a currency value $123.00 or -$123.00.

Why would setting the EditAsType affect the display of a readonly field? Shouldn't there be a property named DisplayAsType or something like that?

How can I keep the currency formattng for a negative number?

I'd like to get parens around the number if it is negative. So that -123.88 appears as $(128.88)

Hi Alex,

Thanks for the reply. Yes I have placed the mask and is working fine now.

Thanks,
