TreeView inside a XamOutlookBar with missing toggle icon
posted

Hi,

I have a TreeView inside a XamOutlookBar. But, the TreeView's default expand/collapse icon is invisible. The functionality is there, I can click on the blank area of the icon and the list will expand/collapse.

How can I make the expand/collapse icon to be visible?

Refer to the image below, by default, there should be an expand/collapse arrow icon at the left of each group (Group 1, Group 1a, Group 1b).

Attached is my xaml code, the treeview and xamoutlookbar items bind from a datacontext from the viewmodel.

Thanks,

Vincent

    Hello Vincent,

    Thank you for your post. I have been looking into it and the code you have provided and I can suggest you use our XamDataTree control instead of TreeView, where the expansion indicator is visible by deafult. Please let me know if you need further assistance on this matter.

    Looking forward for your reply.
