I am using the XamTreeGrid filtering with FilterResultsDisplayMode="ShowWithAncestorsAndDescendants" and FilterAction="Hide"
When children or ancestors are of "filtered in" rows are displayed they are of a very low opacity (0.35 to be exact) which my users find very difficult to read. Snooping around I found this snippet within the themes:
<Trigger Property="IsOpacityReduced" Value="True"> <Setter TargetName="PART_RecordContentSite" Property="Opacity" Value="0.35" /> </Trigger>
Which jives with the documentation on RecordFilterAction.ReduceFilter docs: "Record’s DataRecord.IsFilteredOut, property will be updated as well as the RecordPresenter's RecordPresenter.IsOpacityReduced. The default templates trigger off this property to set the RecordContentSite Opacity."
I would like to set this opacity value to something much higher without re-templating the content presenter. I've tried several things without the desired results, including this style:
<Style TargetType="ContentPresenter"> <Style.Triggers> <DataTrigger Binding="{Binding RelativeSource={RelativeSource AncestorType=igDP:DataRecordPresenter}, Path=IsOpacityReduced}" Value="True"> <Setter Property="Opacity" Value="0.85"/> </DataTrigger> </Style.Triggers> </Style>
Any suggestions?
Alternative angle to the same problem: is there a way I can prevent the DataRecordPresenter from being flagged as IsOpacityReduced when showing as an ancestor or dependent. If so then I think I can style these rows based on IsFilteredOut and IsVisible flags.
Hello Matthew,
The filtered out rows' opacity in the XamTreeGrid are updated in accordance to the item that is filtered in and all filtered out items are expected to have a reduced opacity because the DataRecordPresenter's IsOpacityReduced readonly property is set to true. Therefore the behavior is considered an all or nothing approach changing the opacity is considered to be a new product idea.

This is not really helpful, but thanks for copy/pasting that standard response for me. My customers can't read the data when it is presented in this fashion. To subumit an idea, cross my fingers and hope that it will be considered and then wait for it to prioritized implemented and deployed... I can't keep my customer waiting that long.
Thank you for the recommendation.
Hello Matt,
Thank you for your reply. I've attached a sample that demonstrates how to modify the DataRecordPresenter style in the App.xaml. I made the opacity equal to 1 when the filter occurs.
Let me know if you have any additional questions.
