Hello Petar.

Thanks for the reply.

I have managed to solve it using the "DataLoaded" event and now it works for me, it is probably because I use a template to change the presentation of the search panel, although it is the same for both grids. I use no-xaml libraries.

I use this event because it comes after the OnApplyTemplate.

DataGrid.DataLoaded += OnDataGridDataLoaded;

AuxiliaryDataGrid.DataLoaded += OnDataGridDataLoaded;

private void OnDataGridDataLoaded(object sender, EventArgs e)
{
    var gridView = sender as RadGridView;
    if (gridView.SearchStateManager != null)
    {
        gridView.SearchStateManager.IsSearchWithAccentEnabled = true;
        gridView.DataLoaded -= OnDataGridDataLoaded;
    }
}

Thank you so much.

Hello Petar.

I use 2022.3.912 GridView trial release with Visual Studio 2022 and net 7. I have two GridViews, one is binding to an ObservableCollection<Entity>() (Entity is a dbset ef core) and other is binding to a ObservableCollection<dynamic>().

In the ViewModel:

For the first GridView:

private ObservableCollection<TEntity> items;

public ObservableCollection<TEntity> Items
{
    get => items;
    set => SetProperty(ref items, value);
}

For the second GridView:

private readonly object locking = new();

private ObservableCollection<dynamic> auxiliaryItems = new();

public ObservableCollection<dynamic> AuxiliaryItems
{
    get => auxiliaryItems;
    set => SetProperty(ref auxiliaryItems, value);
}

In th Window Loaded event:

<i:Interaction.Triggers>
    <i:EventTrigger EventName="Loaded">
        <i:InvokeCommandAction Command="{Binding WindowLoadedCommand}" CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}" />
    </i:EventTrigger>
</i:Interaction.Triggers>

public ICommand WindowLoadedCommand => new Prism.Commands.DelegateCommand<object>(async (o) => await OnWindowLoaded(o).ConfigureAwait(false));

private async Task OnWindowLoaded(object obj)

{

    window = obj as MainWindow();

    BindingOperations.EnableCollectionSynchronization(AuxiliaryItems, locking);

    window.DataGrid.Loaded += OnDataGridLoaded();

    window.AuxiliaryDataGrid.Loaded += OnDataGridLoaded();

}

private void OnDataGridLoaded(object sender, RoutedEventArgs e)
{
    var gridView = sender as RadGridView;
    if (gridView.SearchStateManager != null)
    {
        gridView.SearchStateManager.IsSearchWithAccentEnabled = true;
    }
}

For the first datagrid, SearchStateManager is ok but for the second grid it's null.

The first time records are loaded into the grid the searchdatasource is null, but the second time it is not.

AuxiliaryItems = new ObservableCollection<dynamic>(itemsSource);

if (window.AuxiliaryDataGrid.SearchStateManager != null)
{
    CommonWindow.AuxiliaryDataGrid.SearchStateManager.IsSearchWithAccentEnabled = true;
}

This is the way I load the records.

Sorry for my english.

Best regards.

Hello. Sometimes the SearchStateManager is Null even though ShowSearchPanel is true.

I bind an ObservableCollection<dynamic>() to ItemsSource and I load different objects.

When the DataGrid is first Loaded, the SearchStateManager is null, but when I reload other objects in the ObservableCollection the second time it's not.
