I currently have a Loop going through a cube which returns the name (Caption) of its items.
However as this is an OLAP cube I want to distinguish between user defined and attribute hierarchies. I thought the best way to do this would be to give each one a different color (so give User Defined Hierarchies a blue font and Attribute Hierarchies a red font for example).
I thought this would be simple but the method I tried below threw alot of errors, while other methods turned all of the items a particular colour rather than just the items I wanted.
Has anyone got an idea of how I could change an items colour depending on its value??
Window1.xaml.cs
foreach (Hierarchy hierarchy in dimension.Hierarchies)
{
Dimension HierarchyItem = new Dimension();
HierarchyItem.Caption = hierarchy.Caption;
DimensionItem.SubDimensions.Add(HierarchyItem);
HierarchyItem.IsDraggable = true;
if (HierarchyItem.Caption == "Account Number")
HierarchyItem.Caption = Brushes.Red)
else if (HierarchyItem.Caption == "Customer Number")
HierarchyItem.Caption = Brushes.Blue)

Hello James,
You can have an observable Brush property on your business class, say
public Brush TitleBrush { ... }
Then in the TreeView's ItemTemplate (the HierarchicalDataTemplate) you can bind the Foreground of the TextBlock there to this property:
Foreground="{Binding TileBrush}"
Does this work for you?

Nearly, but I still get an error.....
HierarchyItem.TitleBrush.Add(TitleBrush)
I am still trying to get the colour of the text to change depending on its text value (Caption) but it tells me that I cannot convert the observable collection to media brush.
Am I just missing something simple??

Hi James,
I prepared a sample project implementing Miro's suggestion. Can you take a look at it and let me know if it works for you or if your scenario requires a different approach.
