Hi maliming,

That last change you suggested was the solution. Everything appears to be working now.

Right now I have that code in OnApplicationInitialization and these settings in appsettings.json

"Azure": { "SignalR": { "Enabled": "true" } }

{ "Azure:SignalR:ConnectionString": "Endpoint=https://xxxxxxx.service.signalr.net;AccessKey=xxxxxxxxxx=;Version=1.0;" }

Getting this error after implementing as suggested.

This exception was originally thrown at this call stack: [External Code] AzureSignalRPoc.Blazor.AzureSignalRPocBlazorModule.OnApplicationInitialization.AnonymousMethod__16_0(Microsoft.AspNetCore.Http.HttpContext, Microsoft.AspNetCore.Http.RequestDelegate) in AzureSignalRPocBlazorModule.cs

public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
    var env = context.GetEnvironment();
    var app = context.GetApplicationBuilder();

    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.UseAbpRequestLocalization();

    if (!env.IsDevelopment())
    {
        app.UseErrorPage();
        app.UseHsts();
    }

    app.UseAbpSecurityHeaders();
    app.UseStaticFiles();

    app.UseAuthentication();
    app.UseAbpOpenIddictValidation();

    if (MultiTenancyConsts.IsEnabled)
    {
        app.UseMultiTenancy();
    }

    app.Use(async (httpContext, next) =>
    {
        var authenticateResultFeature = httpContext.Features.Get<IAuthenticateResultFeature>();
        if (authenticateResultFeature != null && authenticateResultFeature.AuthenticateResult == null)
        {
            if (httpContext.User.Identity?.IsAuthenticated == true)
            {
                authenticateResultFeature.AuthenticateResult = AuthenticateResult.Success(new AuthenticationTicket(httpContext.User, httpContext.User.Identity.AuthenticationType!));
            }
        }

        await next(httpContext);
    });

    app.UseUnitOfWork();

    app.UseAuthorization();
    app.UseSwagger();
    app.UseAbpSwaggerUI(options =>

The suite doesn't really respect custom code blocks. Especially the .Extended classes.

It would be best if those got ignored unless the file is completely missing.

Also unit tests really need a . Extended class

On Blazor Server

Issues arise when editing data: occasionally, changes to fields are not saved, and at times, modifications result in required fields being emptied.

After upgrading from 8.0.2 to 8.0.3 with Blazor Server project we get this error on startup.

System.TypeLoadException: 'Method 'ButtonStretchedLink' in type 'Blazorise.Bootstrap5.Bootstrap5ClassProvider' from assembly 'Blazorise.Bootstrap5, Version=1.3.2.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.'

That worked. Thanks.

Here's my final code for reference.

            var arguments = GetToolbarComponentArguments();
            Toolbar.AddComponent<DataGridColumnVisibilitySelector>(arguments);
            


        private Dictionary<string, object?> GetToolbarComponentArguments()
        {
            var arguments = new Dictionary<string, object?>();

            EventCallback<bool> NotesCheckedValueChanged = EventCallback.Factory.Create<bool>(this, UpdateNotesCheckedValue);
            arguments.Add(nameof(NotesCheckedValueChanged), NotesCheckedValueChanged);


            return arguments;
        }
        

        private async Task UpdateNotesCheckedValue(bool checkedValue)
        {
            NotesColumnVisible = checkedValue;
            await Task.CompletedTask;
        }

              </DataGridColumn>

• ABP Framework version: v8.0.2
• UI Type: Blazor Server
• Database System: EF Core (SQL Server)
• Steps to reproduce the issue:

We built a button dropdown component designed to control visibility of columns on the Blazorise DataGrid.

This component works fine when embedded in the body of the page. We would like to move the button to the Toolbar to keep the look and feel consistent.

We are having trouble figuring out how to access event callbacks from the toolbar contributor.

We try to add the component like this but the event callbacks don't work.

        var arguments = new Dictionary<string, object?>();
        arguments.Add("SelectAllCheckedValue", SelectAllCheckedValue);
        arguments.Add("TestDateCheckedValue", TestDateCheckedValue);
        arguments.Add("AttachmentsCheckedValue", AttachmentsCheckedValue);
        arguments.Add("AttachmentsCheckedValueChanged", AttachmentsCheckedValueChanged);
        Toolbar.AddComponent<SubstanceAbuseTestsDataGridColumnVisibilityComponent>(arguments);

Here is the component referenced on the razor page.

    <DataGridColumnVisibilityComponent @bind-SelectAllCheckedValue=SelectAllCheckedValue
                                       @bind-TestDateCheckedValue=TestDateCheckedValue
                                       @bind-AttachmentsCheckedValue=AttachmentsCheckedValue />

Here is the code behind c#

protected bool TestDateCheckedValue { get; set; }

protected bool AttachmentsCheckedValue { get; set; }

protected bool SelectAllCheckedValue { get; set; }

protected async Task SetColumnVisibilityAsync()
{
    // ToDo bind cookie here
    SelectAllCheckedValue = true;
    TestDateCheckedValue = true;
    AttachmentsCheckedValue = true;
}        protected bool TestDateCheckedValue { get; set; }

protected bool AttachmentsCheckedValue { get; set; }

protected bool SelectAllCheckedValue { get; set; }

protected async Task SetColumnVisibilityAsync()
{
    // ToDo bind cookie here
    SelectAllCheckedValue = true;
    TestDateCheckedValue = true;
    AttachmentsCheckedValue = true;
}

Here is the component.

@page "/DataGridColumnVisibility"

<Dropdown>
    <DropdownToggle Color="Color.Primary">
        <Icon Name="IconName.Eye" /> Field Visibility
    </DropdownToggle>
    <DropdownMenu >
        <DropdownItem ShowCheckbox Checked="SelectAllCheckedValue" CheckedChanged="UpdateSelectAllCheckedValue">Select All</DropdownItem>
        <DropdownDivider />
         <DropdownItem ShowCheckbox Checked="TestDateCheckedValue" CheckedChanged="UpdateTestDateCheckedValue">Test Date</DropdownItem>
         <DropdownItem ShowCheckbox Checked="AttachmentsCheckedValue" CheckedChanged="UpdateAttachmentsCheckedValue">Attachments</DropdownItem>
    </DropdownMenu>
</Dropdown>

 @code {
    [Parameter]
    public bool SelectAllCheckedValue { get; set; }

    [Parameter]
    public EventCallback<bool> SelectAllCheckedValueChanged { get; set; }

    async Task UpdateSelectAllCheckedValue()
    {
        SelectAllCheckedValue = !SelectAllCheckedValue;
        TestDateCheckedValue = SelectAllCheckedValue;
        AttachmentsCheckedValue = SelectAllCheckedValue;

        await SelectAllCheckedValueChanged.InvokeAsync(SelectAllCheckedValue);
        await TestDateCheckedValueChanged.InvokeAsync(TestDateCheckedValue);
        await AttachmentsCheckedValueChanged.InvokeAsync(AttachmentsCheckedValue);
    }


    [Parameter]
    public bool TestDateCheckedValue { get; set; }

    [Parameter]
    public EventCallback<bool> TestDateCheckedValueChanged { get; set; }

    protected async Task UpdateTestDateCheckedValue()
    {
        TestDateCheckedValue = !TestDateCheckedValue;
        await TestDateCheckedValueChanged.InvokeAsync(TestDateCheckedValue);
    }

    [Parameter]
    public bool AttachmentsCheckedValue { get; set; }

    [Parameter]
    public EventCallback<bool> AttachmentsCheckedValueChanged { get; set; }

    protected async Task UpdateAttachmentsCheckedValue()
    {
        AttachmentsCheckedValue = !AttachmentsCheckedValue;
        await AttachmentsCheckedValueChanged.InvokeAsync(AttachmentsCheckedValue);
    }
}

We use this on the Displayable property of the DataGrid column

<DataGridColumn TItem="ExampleDto"
                 Field="TestDate"
                 Displayable=TestDateCheckedValue
                 Editable="true"
                 Caption="@L["TestDate"]">
     <DisplayTemplate>
         @context.TestDate.ToShortDateString()
    </DisplayTemplate>
</DataGridColumn>
    [Parameter]
    public EventCallback<bool> AttachmentsCheckedValueChanged { get; set; }

    protected async Task UpdateAttachmentsCheckedValue()
    {
        AttachmentsCheckedValue = !AttachmentsCheckedValue;
        await AttachmentsCheckedValueChanged.InvokeAsync(AttachmentsCheckedValue);
    }
}
