The normal common problem -- the check box in the header with filtration doesn't align with the grid data checkbox... 

The data comes from a datasource set to a bindinglist of a list of class with many bool properties. 

I'm thinking if I can get the  header and data to left align the check boxes would line up?.. I tried this example but it then says it can't do it with a simple datasource set?... What is the magic to get such simple functionality working in WPF xamgrid? I am doing no custom addition of checkboxes just letting the default happen which is otherwise perfect.  like "<igDP:Field Name="theDataColumn" Label="A Data Column" />

<igDP:FieldSettings.FilterCellEditorStyle>
<Style TargetType="{x:Type igEditors:XamCheckEditor}">
<Setter Property="Margin" Value="18,0,0,0"/>
</Style>
</igDP:FieldSettings.FilterCellEditorStyle>

This is a very obvious problem with your product that you guys should have cared enough to resolve from seeing it in testing.
