[DevExpress Support Team: CLONED FROM T189619: TileView is not refreshed when a datasource is changed]
Hello supporters,
I am currently experiencing the above phenomenon.
My version is '18.1.6'
The only difference is that my datasource is a List Type…
please check…
Hi,
List<T> does not support data change notifications. That is why GridControl as well as any data-aware control cannot know of such changes to refresh its content. If you need to reflect data changes automatically, it is necessary to use BindingList<T> that supports a special ListChanged event. In this case, GridControl will update its content when you add/remove rows. If you need to update its content when property values are changed, your underlying data object should support the INotifyPropertyChanged interface.
I should note that these binding specifics are common for all data-aware WinForms controls.
Alternatively, you can refresh grid data manually by calling the TileView.RefreshData method.
Let me know if this information is helpful.
Hi,
I changed the List to BindingList as you said.
However, is still only updates the BindingList, not TileView.
Just like the previous one, go back to the previous item and come back and see it updated.
I also changed my data structure by inheriting INotifyPropertyChanged, but the result is the same.
TileView.RefreshData() is same…
Only modification of my data is reflected in TileView without any problems, but the addition and remove are not reflected directly in TileView, but it is reflected when I go to another item.
Hi,
I cannot reproduce the issue. Feel free to modify my sample to illustrate how to see the shortcoming.
I look forward to your response.
