We do not have this implementation out of the box.
You can do the following:
Create a control that inherits Composite control. Then add enum Displaymode where you will have two modes - Libraries and Items.
In a user control - that will be your template you should add one repeater - that will lists your libraries and in another holder where you should have the ImageGallery control ( which displays gallery items).
In your custom control that inherits composite control you should check the current display mode and depending on it you will hide/show the repeater with the libraries and image Gallery control. You can also add "back" button when a user is in items mode which will return to libraries mode when clicked. If a gallery is selected you need to associate the parentIDs
array with library ID to return the files for the specified library.
|Guid parentIDs = new Guid[listofAllLibrries.Count];
| for (int i = 0; i < listofAllLibrries.Count; i++)
| ILibrary lib = listofAllLibrries[i] as ILibrary;
| parentIDs[i] = lib.ID;
All the best,
