Filtering causes Unhandled exception #459

Closed Grandizer closed 2 years ago

Grandizer commented 2 years ago

Describe the bug We have been using your components for a while and enjoy them. I cannot say that I have specifically used the filter in quite a while, but we have implemented it on list boxes and grids and such. It all worked great. Now filtering anywhere seems to be broken, no matter what the component.

To Reproduce

<RadzenListBox AllowFiltering="true"
  FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive"
  @bind-Value=@SelectedContributorIds
  Multiple="true"
  Data=@AllContributors
  TextProperty="Value"
  ValueProperty="Key"
  Class="w-75" />

public IEnumerable<int> SelectedContributorIds { get; set; } = new List<int> { };

public List<KeyValuePair<int, string>> AllContributors { get; set; } = new();

AllContributors.Add(new KeyValuePair<int, string>(1, "First Person"));
AllContributors.Add(new KeyValuePair<int, string>(2, "Second Person"));
AllContributors.Add(new KeyValuePair<int, string>(3, "Third Person"));
AllContributors.Add(new KeyValuePair<int, string>(4, "Fourth Person"));
AllContributors.Add(new KeyValuePair<int, string>(5, "Fifth Person"));
AllContributors.Add(new KeyValuePair<int, string>(6, "Sixth Person"));

Expected behavior I expect the filter to work and not throw an error.

I have a DataGrid as well.

  IsLoading="!IsLoaded"
  AllowFiltering="true"
  AllowPaging="true"
  AllowSorting="true"
  FilterMode="FilterMode.Simple"

  EmptyText="There are no records found"
  PageSize="12">

Additional context This seems to be globally throughout the project. The error is not pointing me in any particular direction. Any suggestions?
