I'm kind of new to MVC (been programming for about 6 months), I'm looking for some help trying to learn standard coding in mvc, I already have my model and classes separate in another project but what I'm looking for is things like exception handling, standard view messages for example I have a class called returnMessage and through this I send anything I want back to my view (in ViewBag) and display it there, so if you could guide me thought or give me some articles to read that would be fantastic.
Regards, Mr.K

My advice would be to get a book on MVC and just go through it. The ViewBag is ok, it "works" but it's not really best practice, you'll want to use models to pass data to your views as they are strongly typed and can contain the logic they need. Obviously no-one can explain all of the issues and standards to do you in a forum post which is why it's best to get a book on MVC as that should take you through everything you need to know.

You may check coding guidelines rather than standards that will help you learn and make feasible application
highlighted points are as below
- DO separate the model its own project with a distinct assembly
- DO put all business logic in the model.
- DO put all validation logic in the model
- DO define interfaces for data access
- DO put all session logic in the model
- DO put HTML in Views and Partial Views (not in a controller).

Please suggest any solution

The solution is to investigate why the system cannot find that file.

There is no file in with this name in PROD also but PROD is not throwing any error
and Also error will be gone if you refresh the page

Sounds like the working server has the Visual J# redistributable installed, and the non-working server doesn't.
Try installing the relevant v2 package from Visual J# Home[^].
Alternatively, try upgrading to the most recent version of the AJAX Control Toolkit[^], which shouldn't have any dependency on Visual J#.

I need to enable my admin user to change access permissions for users on the fly, such that they can create new Roles and add permissions to those Roles and assign that role to any user at run time.
I don't want to 'set' the roles during development, as in [Authorize(Roles="Role1, Role2")] etc because after development if i add roles to any user then again i have to recompile the code and copy the changed dll to project bin folder.
we often hard code the role name with authorized attribute but what if i need to do this kind of association at run time in asp.net mvc project. is it possible please discuss all your thought.
i have seen your have good control on role base access system development. so please guide me how can i add roles to action or controller at run time.if possible please discuss this topic with sample code.
thanks

A quick google would get you recent discussions with sample code.
Attributes are compiled, and you can't add one without recompiling. The idea is to define "roles" for certain tasks, and assign a user to that role if he/she is allowed to do so.
Not to add/remove roles as users are removed/added.

So, one day the action method is executed by role 1, and the next day by role 2?
That's how it works; you assign "admin" to the action method, and assign a user to that role if he/she is allowed to execute. You do not change the role.

hello how to put multiple entries from different pages to the same gridview table.
|
|
|
|
|
For this, either you will need to store those entries to localStorage db, otherwise have a database working that will store the data entered on those 2 pages.
Then load that data from database, to show on a single page within GridView table. If you are having some sort of storing mechanism, consider sharing so that I can guide you specific for that — Session, localStorage, SqlConnection... What?

Hello, I am storing data in database. Program is like x1 is asking for some info. X2 and X3 has to provide those info. database has table in which approx 20 columns are present. 5 columns are used by x1. x2 and x3 have to access rest column. three pages for x1,x2 and x3 has been created to access same table.For X1 this is insert command and for x2 and x3 update command has been used as per selected row to fill the entry.even if i use labels to get the entry of X2 while putting entries by x3 through text box and try to add both entries,this is not working. when x2 enters in same cell entry of x3 gets erased and vice versa.
this is whole problem .
please guide

Of course it does, because you are using UPDATE query. That query will simply ignore the previous data and overwrite it with the newer data.
Can you show the table structure, or the code being used? In any circumstances, you will have to rewrite the query to remove the updation of columns by x3 that x2 has to write. So in this case, all 3 of these x will have a different column to write in, x1 will create a new record, x2 will enter details in a few, and x3 will enter the data to a few.
If you do not want to modify your SQL queries, then chances are you will have to write a lot of validations — such as checking if data exists, and executing if data IS NOT NULL etc. That will just make things over confusing as well as complex.

Take a peek! This is my controller:
public ActionResult SaveInfo(GetOrderDetail_Result items) //This method will call a stored proc to pass parameters
{
var hold = items.Master_OrderNum;
//cb.SaveAgentViewInfo(master_OrderNum);
return View(Index());
}
When I pass the model to the Action method none of the properties are initialized from the view page.
The master_OrderNumnumber comes through as a null.
I'm calling this in my View:
document.location = '@Url.Action("SaveInfo", "ControllerName", new { Model })';
I actually use a foreach(var item in Model) to print certain things to divs on the cshtml page and all that works perfectly. But after passing that same model everything is blank inside in the controller. I don't know what side it should be initialized on. I'm new to MVC!
Help!!

I have created an ASP.NET Core website which will be a template for future web sites. I have removed Bootstrap and included W3.CSS instead, which I find easier to use and just as rich in function as Bootstrap. I have also included npm, gulp and bower and seeded them with the tools I use. I have this saved in a directory.
My problem now is that if I create a new website, I cannot find any way to include this template as the starter set. Conversely, if I open my template, I cannot find any way to save it under a new name in another directory. Every option seems to involve overwriting the template. Does anyone have any suggestions?
I know someone will say that this is easy, so in my defence, I am pleading old age and stupidity in advance.

I cannot understand this point, .NET Core applications just require a main class and a JSON (in future; MSBuild) file for settings. Other stuff is not required at all, and since everything is managed "in current directory", you can place it anywhere on your device and run,
$ dotnet restore
$ dotnet run
And that will work perfectly — for .NET Core console applications as well as ASP.NET Core web applications. If this is Visual Studio, then there are some other settings in Visual Studio that cause some issues such as launchSettings.json file etc.
A simple walk around this would be, publish that template on GitHub and each time you want to create a new project, just clone it in your own local environment.

I want to create a Visual Studio ASP.NET Core MVC website template to my own specification. As I said, I want to remove Bootstrap and use W3.CSS. It seems to be impossible to save it and then use it as a template later.
Your suggestion of using GitHub is worth pursuing. I have never used GitHub but I will investigate it.

Hi all,
I am writing type script files and have a tsconfig file, I am able to run those files and place the js files in one output directory, but I want to be able to place outDir in one tsconfig file because I want to place related .js files into one outDir so that bundling can be easy for me in loading them on demand. Any sort of help will be very helpful, I am new to the MVC and front end technologies. Thanks in advance and happy new year 2017 
Here is my tsconfig looks like, in the below tsconfig code I want to put the search.js file in different outDir, File834.js in different folder and both Validation.js, Calculator.js in one another outDir, can anybody please help me.
{
"compilerOptions": {
"module": "system",
"noImplicitAny": true,
"noEmitOnError": true,
"sourceMap": true,
"target": "es5",
"outDir": "./Scripts/Search"
},
"files": [
"./src/search.ts",
"./src/File834.ts",
"./src/Validation.ts",
"./src/Calculator.ts"
],
"compileOnSave": true
}
Thanks,
