Set Filter on new Data

[vaclav-domin]

I need apply filter after loading data
Now:
Load data (Obsarvable collection)
Create CollectionViewSource
Apply saved filter to columns (column.SetFilter(savedfilterforcolumn))

Filters on columns are visible, but filters don't apply.
Missing solution or missing step?

Thanks

Can you provide a small sample project to reproduce this?

[tom-englert]

Did you do it the same way as in the sample?

Yes, this is solution!
Thanks

Oh now.
Sample code

    public virtual void AfterLoadData()
    {
        if (Data == null) return;
        if (ViewSource != null) ViewSource.CurrentChanged -= ViewSource_CurrentChanged;

        ViewSource = (ListCollectionView)CollectionViewSource.GetDefaultView(Data);
        //obnovit seskupení
        var gc = GridColumns.Where(x => x.SortDirection != null).ToList();
        ViewSource.CurrentChanged += ViewSource_CurrentChanged;
        foreach (var c in gc)
        {
            ViewSource.SortDescriptions.Add(
                    new SortDescription(c.SortMemberPath, c.SortDirection.Value)
                );
        };
        GroupInfoList.Where(x => x.IsGrouping).OrderBy(x => x.GroupingLevel).ToList()
            .ForEach(x => { ViewSource.GroupDescriptions.Add(new PropertyGroupDescription(x.ColumnName)); });
        
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("Data"));
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(SavedSelectedViewName)));
        
        //SetGridFocus();
        System.Windows.Threading.Dispatcher.CurrentDispatcher.Invoke( new Action(() => { 
                RestoreColumns(); 
                ViewSource.Refresh();
        }), System.Windows.Threading.DispatcherPriority.ContextIdle);
        ViewSource.Refresh();
    }




    public virtual void RestoreColumns()
    {
            try
            {
                List<ColumnInfo> columnInfoList = DataGridViewSettings.Default.ColumnSettings;
                if (columnInfoList != null)
                {
                    var sorted = columnInfoList.OrderBy(x => x.DisplayIndex);
                    foreach (var itm in sorted)
                    {
                        GridColumns[itm.ColumnIndex].DisplayIndex = itm.DisplayIndex;
                        GridColumns[itm.ColumnIndex].Visibility = itm.Visible ? Visibility.Visible : Visibility.Hidden;
                        GridColumns[itm.ColumnIndex].Width = new DataGridLength(itm.Width, itm.UnitType);
                        GridColumns[itm.ColumnIndex].SortDirection = itm.SortDirection;
                        GridColumns[itm.ColumnIndex].SetFilter(itm.ColumnFilter);
                    }
                }
            }
            catch
            {
            }
            finally 
            {
            }
        }

    }
