Error Page , 404, 500 - ASP.NET Discussion Boards

You have not given enough details of your problem.

But if I get it correctly you want to remove cascading dropdown behavior to display data in grid view, if yes then you can implement the drop down change event to display the data for each of them.

Whenever you have SelectedIndexChange event fired you can check the currently selected dropdown controls and prepare the data to bind to your grid control.

yes you are right...actually i dnt want to remove anything but its that i want to add on more feature which is that....on every dropdown selection it should show the data in gridview

So you may add a method to bind the data to grid view and make it visible.

Call this method on each SelectedIndexChange event and apply whatever business logic you have on selection change of current dropdown control and bind necessary data to your grid.

Hi Friends,

I need your help.

Recently i got assignment to work on MVC based project.

Now i am well familiar with Traditional ASP.NET Web Forms & how it works..but not that much with MVC. So i need your general/overall guidance.

Consider a situation that i need to build internet based site wherein

a- Customer fills-in Registration page

b- Later when Admin logs-in the site, Admin can see List of Pending requests in the grid.

consider having columns like FirstName, LastName, Address, City, State in the Grid. First column in grid will have Image-with-Hyperlink

c If admin clicks on any record, again Registration page will open, admin can see details filled-in by user. Here admin can perform any of below 3 activities.

c1- Admin can modify any of these details & add few notes/comments, via Submit-Button.

c2- Admin can Approve request, via Submit-Button.

c3- Admin can Reject request, via Submit-Button.

After performing any of 3 above action, screen will go back to Pending-Request-Grid.

Approved/Rejected User will Not be shown in this grid.

d- Now Approved User will get shown into another grid call Manager Users.

Manage-User-Grid will have same info as Pending-Request-Grid, but here Image-Hyperlink will allow admin to disable a user Or will allow Edit user info.

Now considering above situation, i tried started developing MVC 5 based Web Application Project but i see that lot of features are coming into picture e.g. Partial-View, ViewModel, Entity Framework, Linq.

So it happens that, to complete Task-A, i implement one feature e.g. LINQ and after sometime, to complete Task-B, i got another article which show using Entity Framework. So again i need to create Few Classes, Delete Few Classes, Delete some code...

This kind of thigns takes more time & lot of times...working things get stopped.

I want to use below features in this project:

Entity Framekwork, Partial View, Strogly Typed View, Stored Procedure base Data Read/Modify

So what i want from you:

Q-1- Can you please tell me, which task to do 1st, so i can implement above fetures ?

Q-2 Also there are pages which has 2 List boxes. Means 2 Tables data need to be retrieved & displayed. So what is good method to display Multiple Tables data in the view, in current situation.

Note: This is small internet based site, but not having too much traffic. Also there is no Mobile-App reading this data.

So can you guys please help me...!!!

Any thoughts/article/video/link are welcome...!!!

Thanks
Devsql

I believe you are getting confused in MVC probably it's new for you so you are ending up rewriting a lot of code as you mentioned here. I will suggest to spend some time on MVC first so you will get a better idea and to code further. There is no special pattern for each of page you mention but you have to choose which is best suite you.

I thought I had this worked out in my main project, then I created a lite version of the project.
I can't figure out how to get my error handler page to work.

What works
Exception Pages when a page fails, I get the Exception message.

What doesn't work
when I have the URL up say Home, and I type in /Home/jllk;lk;lk;l junk, I expect to get the /Error/Page404 or /Error/Page500

What happens
I get a blank page with nothing.

What I have going
Web Config - This was suppose to handle page not found.

<customErrors mode="On">
  <error statusCode="404" redirect="~/Error/Page404" />
  <error statusCode="500" redirect="~/Error/Page500" />
</customErrors>

So this runs in Global.asax

void Application_Error(object sender, EventArgs e)
        {
            if (HttpContext.Current.IsDebuggingEnabled)
            {
                // Pick up the Exception Error
                HttpException httpException = new HttpException();
                RouteData routeData = new RouteData();

                // Get our current controller and action
                string controller = Request.RequestContext.RouteData.Values["controller"].ToString();
                string action = Request.RequestContext.RouteData.Values["action"].ToString();

                //We clear the response
                Response.Clear();
                Server.ClearError();

                // Validate the this controller is legit

                // If the controller exist, use it, or else use the error controller
                if (controller != null)
                    routeData.Values.Add("controller", controller);
                else
                    routeData.Values.Add("controller", "Error");

                // A good location for any error logging, otherwise, do it inside of the error controller.

                //We check if we have an AJAX request and return JSON in this case
                if (IsAjaxRequest())
                {
                    Response.Write("Your JSON here");
                }
                else
                {
                    if (httpException != null)
                    {
                        int httpCode = httpException.GetHttpCode();
                        switch (httpCode)
                        {
                            case 500:
                                Response.StatusCode = 404;
                                Response.ContentType = "text/html";
                                routeData.Values.Add("action", "Page500");

                                // Clear the error, otherwise, we will always get the default error page.
                                Server.ClearError();
                                break;

                            case 404:
                                Response.StatusCode = 404;
                                Response.ContentType = "text/html";
                                routeData.Values.Add("action", "Page404");

                                // Clear the error, otherwise, we will always get the default error page.
                                Server.ClearError();
                                break;

                            default:
                                Response.StatusCode = 404;
                                Response.ContentType = "text/html";
                                routeData.Values.Add("action", "Page404");

                                // Clear the error, otherwise, we will always get the default error page.
                                Server.ClearError();
                                break;
                        }

                        // We can pass the exception to the Action as well, something like
                        // routeData.Values.Add("error", exception);                        

                        // Call the controller with the route
                        IController errorController = new coastEnviromental.Controllers.ErrorController();
                        try
                        {
                            Response.TrySkipIisCustomErrors = true;
                            errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
                        }
                        catch (Exception ex)
                        {
                            Console.WriteLine(ex.ToString());
                            Response.Redirect("Error");
                        }
                    }
                }                

            }
        }

Then the controller fires

public class ErrorController : Controller
    {
        public ActionResult Index()
        {
            return View();
            return View("Page404", "Error"); // Also tried
        }

        public ActionResult Page404()
        {
            return View();
        }

        public ActionResult Page500()
        {
            return View();
        }
    }

And I get a blank page.
I tried setting a break point on the View, but It never hits.

If it ain't broke don't fix it

After Easter egg hunting for an hour, I added the string error to the ActionResult and now the View Renders
hmm.........

public class ErrorController : Controller
    {
        public ActionResult Index(string error)
        {
            return View();
        }

        public ActionResult Page404(string error)
        {
            return View("Page404");
        }

        public ActionResult Page500(string error)
        {
            return View("Page500");
        }
    }

If it ain't broke don't fix it

This is not a technical question as it sounds. What are you expecting from here?

Hi,

I have downloaded an Angular JS(or 2) Project to run and learn, its giving me error for both the ng serve and npm start, I am not understanding why Angular creators made my life so hell, no project from Internet I am able run so far and test so that I can learn, I want to learn but I can't do anything if whatever I try if it fails.

When I said ng serve it simply tells me that "You have to be inside an Angular CLI project in order to use the serve command." I am inside a project that I created but I copied the code from online into it. I don't know what to do, if at least one example project if Angular 2 guys can give with a Microsoft Web API would have been good.

Thanks,

Hi Guys. Please provide me with basic steps of creating a C# data access layer and business logic layer.

Step 1. Search Google for articles.
Step 2 to n. study, design, code and test.

Refer below -

Three Layer Architecture in C# .NET[^]

modified 20-Sep-20 21:01pm.

Tutorial 2: Creating a Business Logic Layer[^]

vinuvasahanponniah

Hi
I would advise that you write the data access layer by using the repository pattern. It should return each object/record from the database as it is in the database. The business logic layer will use these repositories to perform crud operations.

The business layer should contain all the business rules for accessing/restricting data, validations etc.
This layer is best implemented with view models(DTO objects) created on it as you might know the data you store in a database might not necessarily the same as it comes from the UI. The presentation layer will use these DTO objects to pass data to the business layer. Hope this makes sense.

HI,

I want to ask a question regarding DropDownList.

This is the code:-

<asp:dropdownlist id="DropDownList1" runat="server"
="" onselectedindexchanged="DropDownList1_SelectedIndexChanged" height="22px" width="77px" autopostback="True">
<asp:listitem>+54 Argentina
<asp:listitem>+93 Afganistan
<asp:listitem selected="True">+91 India
<asp:listitem>+61 Austrila
<asp:listitem>+91 India
<asp:listitem>+32 Belgium
<asp:listitem>+91 India
<asp:listitem>+53 Brazil
<asp:listitem>+359 Bulgaria
<asp:listitem>+86 China
<asp:listitem>+299 GreenLand
<asp:listitem>+33 France
<asp:listitem>+49 Germany
<asp:listitem>+852 HongKong
<asp:listitem>+52 Mexico

So, I want if user select +33 France from DropDownList then in DropDownList it should display +33 FR instead of this full name +33 France which is mention in DropDownList???So,is it possible??? How can I achieve this???

You can see DisplayText set to your control here it is "+33 France" and what you have selected. However, you can have different Value returned for your selection you made.

If you want to see the different text before and after selection for the same control you can't.

modified 20-Sep-20 21:01pm.

What you are trying to do is not a good practice. Why do you want to change the dropdown list after user selected it. Are you making things harder while there might an easier solution for you actually need ???
