Apologize for the delay in sending this.

I created a simple project of UXGridView based on your description.

• The ItemsSource property of UXGridView is bound to PagedCollectionView;
• PagedCollectionView is tied to an ObservableCollection.

..., and the collection is cleared and re-loaded, the UXGridView entirely loses the column footers and they become blank.

Could you please kindly modify my sample by applying "cleared and re-loaded" until reproduce the reported problem. Please send back the modified sample to us to be investigated further.

Yudi,

See attached for an updated sample that exhibits this behavior. 

Basically, implemented a command that does a .Clear(); and then adds new elements to the collection. Cells update fine, the footers however go blank as initially reported.

Let me know if you need anything else.

I made a minor modification to the UXGridViewObservCollStruct Modified.zip file. The modifications are made on the UXPage1ViewModel.cs.

On the UpdateData() method, after clear-ing the existing data I created a new collection of MyData and assign this data to GridDatafin.

ObservableCollection data = new ObservableCollection();
data.Add(new MyData { keyword = "keyword10", sources = "sources10", TestVal = 10 });
data.Add(new MyData { keyword = "keyword11", sources = "sources11", TestVal = 11 });
data.Add(new MyData { keyword = "keyword12", sources = "sources12", TestVal = 12 });
...
data.Add(new MyData { keyword = "keyword19", sources = "sources19", TestVal = 19 });

this.GridDatafin = data;

For more detail, please check the attached UXPage1ViewModel.cs file. Feel free to let us know if you have different result.
