I have a problem with binding of column header.

It's my class :

public string ErrorMessage { get; set; }

public TimeSpan? Duration { get; set; }

public string DefaultObjectTypeCd { get; set; }

public string DefaultObjectValue { get; set; }

public string ObjectTypes {

get {

string s = string.Empty;

foreach (LogObject o in LogObjects) {

if (string.IsNullOrEmpty(s))

s = o.Type;

else

s += "\n" + o.Type;

}

return s;

}

}

public string ObjectValues

{

get

{

string s = string.Empty;

foreach (LogObject o in LogObjects)

{

if (string.IsNullOrEmpty(s))

s = o.Value;

else

s += "\n" + o.Value;

}

return s;

}

}

and I will to bind ObjectValues properties for value and ObjectTypes as Label of column

<dataPresenter:UnboundField

BindingPath="ObjectValues"

Settings="{StaticResource ObjectHeaderGrid}"/>

and style

<dataPresenter:FieldSettings x:Key="ObjectHeaderGrid">

<dataPresenter:FieldSettings.LabelPresenterStyle>

<Style TargetType="{x:Type dataPresenter:LabelPresenter}" BasedOn="{x:Static igThemes:DataPresenterIGTheme.LabelPresenter}">

<!--<Setter Property="TextBlock.Text" Value="{Binding Path=DataItem.ObjectTypes}" />-->

<Setter Property="Template" >

<Setter.Value>

<ControlTemplate>

<TextBlock Margin="8 2 0 0" Text="{Binding Path=DataItem.ObjectTypes}" />

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

</dataPresenter:FieldSettings.LabelPresenterStyle>

</dataPresenter:FieldSettings

The binding it's correct but I lose theme and the theme used for xamdatacards is ==> Theme="IGTheme".

and the result is

The column label is bind but the main theme lose.

Can you help me? how can I recover the main style(theme)??
