SfDataGrid refresh when Collection property changed

[Jakub Olichwier]

Hi,

I want to refresh SfDataGrid when ItemSource (Observable collection) property is changed (changed value).

For standard DataGrid I use the code below and it works. But it doesnt work for SfDataGrid.

WPF
ItemsSource="{Binding CollectionName, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"


C#
public ObservableCollection<SomeClass> CollectionName
{get=> _collectionName; set_collectionName =value;OnPropertyChanged();}}

CollectionViewSource.GetDefaultView(CollectionName).Refresh();

How to make it work for SfDataGrid?

Regards

Jakub

Hi Jakub Olichwier,

We are a little unclear about your scenario. The collection is reinitialized or updated the values updated properly in SfDataGrid. If the data source implements INotifyCollectionChanged interface, then SfDataGrid control will automatically refresh the UI when item is added, removed or while list cleared.

When you add, or remove an item in ObservableCollection, SfDataGrid automatically refreshes the UI as ObservableCollection implements INotifyCollectionChanged. But when you do the same in List, SfDataGrid will not refresh the UI automatically. Please find the sample in the attachment.

Hi Vijayarasan,

Thank you for your reply.

In fact it requiers to clarify it better.

I update properties of object inside observable colelction. It doesn't refresh the UI so I use

A command bind to button to run

CollectionViewSource.GetDefaultView(CollectionName).Refresh();
​

For standard DataGrid it works (refreshes the UI). For SfDataGrid the command above doesn't refresh the UI.
