Dear,

Please note that I encountered an issue when clicking a <ext-button> (MVC) having a direct method as a listeners.
Noting that I tried the same instructions listed in the following page URL:
https://examples.ext.net/#/window/basic/hello_world

Problem description:
when clicking on the button, it alerts the following:

Request Failure (Attached).
Console Error:
ShowWindowDirect:1 Failed to load resource: the server responded with a status of 404 ()

25458



//TestDirect.cshtml

@page
@model FFMSAdminTool.Views.Home.TestDirectModel
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<title>
Hello World - Ext.NET Examples
</title>

</head>
<body>
<h1>Hello World</h1>

<p>
The following sample demonstrates how to configure a new Window and <code>show</code> the Window if closed.
</p>

<ext-button text="Show Window (Client Event)" onClientClick="App.Window1.show();" />

<br />

<ext-button text="Show Window (Direct Event)" onDirectClick="ShowWindowDirect" />

<ext-window id="Window1"
title="Hello World"
height="270"
width="360"
bodyPadding="18"
modal="true">
<content>
This is my first
<a target="_blank" href="https://ext.net/">Ext.NET</a> Window.
</content>
</ext-window>
</body>
</html>





//TestDirect.cshtml.cs

using Ext.Net;
using Ext.Net.Core;
using Microsoft.AspNetCore.Mvc.RazorPages;
using Microsoft.AspNetCore.Mvc;

namespace FFMSAdminTool.Views.Home
{
public class TestDirectModel : PageModel
{
public void OnGet()
{
}

public IActionResult OnPostShowWindowDirect()
{
this.GetCmp<Window>("Window1").Show();

return this.Direct();
}
}
}




Thank you

Hello @Geovision! Thanks for trying Ext.NET 7!

I have tried to recreate the scenario you described with no luck. Even if I created first a directory with Index.cshtml then renamed it to DirectTest.cshtml, also renaming the class name and namespace, the direct event worked.

I can only suspect some missing or different setting you have in Startup.cs might be causing this. I have tried just commenting or changing some settings but I couldn't make it load the page then break the direct event with a wrong path (404).

If I can open http://localhost:5000/TestDirect (thus MyProject/Pages/TestDirect.cshtml) it will always be able to trigger the right path to raise and handle the direct event.

How have you created the project? From VSIX template? dotnet new extnet maybe? I don't really see anything wrong with your code, which is very consistent with the example you pointed.

Please share your projects Startup.cs file. Before sharing, please remove anything from that file that you feel is confidential, although typically there isn't anything.

Hello,

Please find my startUp.cs page:




using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.HttpsPolicy;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

using Ext.Net.Core;

namespace FFMSAdminTool
{
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}

public IConfiguration Configuration { get; }

// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddControllersWithViews();
services.AddExtNet();

}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
// The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
app.UseHsts();
}

app.UseHttpsRedirection();

app.UseExtNetCore();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthorization();



app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
});
}
}
}




Thank you

Hello again, @Geovision!

You have either used an old version of the templates or manually created your project, for what I see in your Startup.cs code. I strongly advise you to update your VSIX or dotnet template and re-create the project. There's no telling what else in the project will need to be fixed before it works otherwise.

It looks like your Startup.cs is based in a prerelease version of Ext.NET, so please re-create the project using a stable release (7.1.0) from one of the supported scenarios. Please check our Ext.NET 7.1 release blog post (https://ext.net/ext-net-classic-7-1-with-new-partial-and-section/), in particular the New Ext.NET templates section.

Let us know if it still doesn't work in your project.

Anyhow, for reference, this is how a current template's Startup.cs file would look like; maybe just by merging the missing parts with yours it may fix the problems you have; try merging it at your own risk -- it is best to rely on the templates. Since stable was released, they shouldn't break between releases.

app.UseResponseCompression();

// 2. Use Ext.NET resources
// To be added prior to app.UseStaticFiles()
app.UseExtNetResources(config =>
{
if (env.IsDevelopment())
{
config.UseDebug(true);
}

config.UseEmbedded();
config.UseCharts();
config.UseThemeSpotless();
});

// 3. Enable Ext.NET localization [not required]
// If included, localization will be handled automatically
// based on client browser preferences
app.UseExtNetLocalization();

app.UseStaticFiles();
app.UseRouting();
app.UseAuthorization();

// 4. Ext.NET middleware
// To be added prior to app.UseEndpoints()
app.UseExtNet(config =>
{
config.Theme = ThemeKind.Spotless;
});

app.UseEndpoints(endpoints => endpoints.MapRazorPages());
}
}
}


Hope this helps!
