Hi I have a unbound treeview. It is populated via Load on demand. I require a style that can set my DefaultImageSrc depending a set of curcumstances, some like

<DataTrigger Binding="{Binding Path=IsFolder}" Value="True">  
                    <Setter Property="DefaultImageSrc" Value="../../folder.png" /> 
                </DataTrigger> 
                <DataTrigger Binding="{Binding Path=IsFolder}" Value="False">  
                    <Setter  Property="DefaultImageSrc" Value="../../diskdrive.png" /> 
                </DataTrigger> 

Can you give me an example

Thanks

Hi Paul,

Please take a look at the following page from the documentation:

If that info does not help you, let me know.

Thanks for your efforts Tihomir ,

Still is still not correct, you are still binding to your "Source", Like I mentioned earlier my treeview is not bound at all, It creates the treeviewitems manually

Hi Paul,

Sorry for the misunderstanding but it seems I am missing something about your scenario. If you are adding manually your treeview items, I believe you should be able to pick the right image and set it in the time when you add the item to the tree. Is that not so? Please elaborate a bit more or send me a sample project which demonstrates the problem.

Hi Tihomir

I think you have answered my initial question (i think), I was hoping to use XAML to set my image for my nodes (style the treeview item) when the tree is in inbound mode. It looks like you cannot do that. I was setting the images in code. 

Am I correct in assuming that you cannot style the treeviewitem when in unbound mode


Thanks

Hi Paul Gallen,

we researched the problem and there is a problem with the binding of this property. We provide you a fix next week with the latest internal build.

All the best,
