Hello.

I'm using a WebDataMenu (Infragistics4.Web.v10.3, Version=10.3.20103.1013) binding it from a WebHierarchicalDataSource whit 3 bindingssources

When I run my project some times the root menu hide some items and clicking in an item and postback the page, the hidden items unhide or viseversa. (these only in a horizontal orientation and EnableScrolling = "true" propperty)

Aparently the items hide for levels example:

In the root bind I have 6 items and the other levels in the first Item.

At the start the webdatamenu shows all items, after the first click only shows 3 items, the next click shows only 1, the next click, show all items again. (Not always is like these; and it is stronger when the control is in a table or cell with position = right)
