My users would like the background of the column header to change when an autofilter is applied.  I presume I need to do something similar to the following:

I can't figure what to put in the trigger property.  I imagine I could use something like AutoFilterValues.Count = 0.  How do I link the ColumnManagerCell to the AutoFilter for the column? 

Hi Jason,

The only way to achieve this type of scenario is to redo the ColumnManagerCell template. In the template, you could add a setter for the background color in the correct section (the MultiDataTrigger that is used to display the AutoFilter glyph when a filter is present on that column). Unfortunately, this is the only way. You can create a hack to change the background using a custom property, but that would require some logic. For best performance and cleanliness, I would suggest redoing the template of the ColumnManagerCell.

The location of the templates can be found on your machine:

C:\Program Files (x86)\Xceed\Xceed DataGrid for WPF Professional Edition v4.3\Themes

In the xaml files, you can find the templates of the controls for those specific themes. If you are using a theme like Media Player 11, then you would need to purchase the Blueprint edition. Or else, you can simply look at the XAML files in the location I provided.

Thanks Marc,

That worked beautifully.  Just added a setter for the Background to the existing multi-trigger.
