Dialog Close?

I've modeled a Dialog from the sample code. The dialog is opened with no problems, but it will never close unless I refresh the page. Whether I click OK, Cancel or choose the X, it stays open. What am I missing?

Opening the Dialog:

<RadzenButton Text="Open" Icon="assignment_ind" Click="@(args => DialogService.Open<UserDetail>($"ID {SelectedUser.O365ID}",
                                            new Dictionary<string, object>() { { "ID", SelectedUser.O365ID } },
                                            new DialogOptions(){ Width = "700px", Height = "530px", Left = "calc(50% - 350px)", Top = "calc(50% - 265px)" }))" Style="margin-bottom:20px" />

As a part of the UserDetail.razor page, I have the following:

<div class="row">
<div class="col-md-12">
    <RadzenButton Click="@((args) => dialogService.Close(true))" Text="OK" Style="margin-bottom: 10px; width: 150px" />
    <RadzenButton Click="@((args) => dialogService.Close(false))" ButtonStyle="ButtonStyle.Secondary" Text="Cancel" Style="margin-bottom: 10px; width: 150px" />

Probably there is an exception that crashed the comm. Check your console output.

I wish there was one! But there are no exceptions being thrown.

@csharp please format the code. This forum supports markdown.

just curious why are you returning bool value if you do not have
DialogService.OnClose += ... defined?
