i am trying to mask xamdatagrid fields so they accept a certain amount of characters. the below code works to an extent. My first problem is that when i enter data into this field, leave, then come back for edit it is hiding the text in the control.  My second question would be how can i make this more generic to use with multiple fields as i have quite a few fields that need to allow only 50 characters in this grid.

thanks in advance

<igDP:Field Name="ID" Label="{Binding Path=Id, Source={x:Static Internationalization:CultureResources.CultureStrings}}">
                                        <igDP:Field.Settings>
                                            <igDP:FieldSettings>
                                                <igDP:FieldSettings.EditorStyle>
                                                    <Style
                              TargetType="{x:Type igEditors:XamMaskedEditor}" >
                                                        <Setter
                                  Property="Mask"   Value="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"/>
                                                    </Style>
                                                </igDP:FieldSettings.EditorStyle>
                                            </igDP:FieldSettings>
                                        </igDP:Field.Settings>
                                    </igDP:Field>
