Hi Dugr,
Was trying to achieve the same thing as yourself, playing with what Marc sent through I came up with:
<
xcdg:Column FieldName="Field1" ReadOnly="True" Title="Field with lots of text to be wrapped" MaxWidth="100" TextWrapping="WrapWithOverflow" >
<xcdg:Column.TitleTemplate>
<DataTemplate>
<TextBlock TextWrapping="Wrap" Text="{Binding}" MaxWidth="100"/>
</DataTemplate>
</xcdg:Column.TitleTemplate>
</xcdg:Column>
which appears to do the trick, I feel that the solution Marc offered is the way to go as it allows dynamic configuration through the resources, rather than doing the template on the column as I have, however this at least gave me an idea of what was going on. Hopefully this can be of use to you.
thanks
Dave
