I have opened up a SharePoint modal dialog to show document library. The Document library contains a hierarchy of folders.
When I reach to the 2nd level of folders there is no option to go back to the parent folder. How can we get such an option?
Putting the helpful response above aside... What we need is for Microsoft to deliver a usable product, 'out of the box', that has a navigate to parent folder/back button.
Jon,
What you need is a Breadcrumb control for your Document Library view, there are some available:
For SharePoint 2010:
SharePoint 2010: Bread Crumb for List/Library View Web Part in Wiki Page.
Adding a Breadcrumb to Document Library Web Parts in Sharepoint 2010
For SharePoint 2013:
