I am trying to format the grid like this. when i do like this the style does not applied at the first instance, where as if you sort the grid one or two times then this formating applies, where as it works at the first instance for :NotContainingConditionalFormatRule StyleToApply="{StaticResource OrangeColumnStyle}

<ig:GreaterThanConditionalFormatRule StyleToApply="{StaticResource OrangeColumnStyle}">
<ig:GreaterThanConditionalFormatRule.Value>0</ig:GreaterThanConditionalFormatRule.Value>
</ig:GreaterThanConditionalFormatRule>

Any idea? Is it a bug? any work around
