I am applying the following style to the grid and the row selector starts from 0:

<Style x:Key="itemIndexSelectorStyle"

TargetType="{x:Type xcdg:RowSelector}">

<Setter Property="Content"

Value="{Binding RelativeSource={RelativeSource Self}, Path=ItemIndex}"/>

</Style>

What needs to be done to start the Row selector index from 1?
