I am trying to create to create two dynamic TextBoxes on Button click1.  The first time i click i get 2. 

The second time 4 ans so on when I only want two (2)



protected void Page_PreInit(object sender, EventArgs e)
{
List<string> keys = Request.Form.AllKeys.Where(key => key.Contains("txtDynamic")).ToList();
int i = 1;
foreach (string key in keys)
{
this.CreateTextBox("txtDynamic" + i);
i++;
}

}

protected void Button1_Click(object sender, EventArgs e)
{
int index = pn1TextBoxes.Controls.OfType<TextBox>().ToList().Count + 1;
this.CreateTextBox("txtDynamic" + index);


}

private void CreateTextBox(string id)
{
for (int i = 1; i <= 2; i++)
{
TextBox txt = new TextBox();
txt.ID = id + i.ToString();
txt.TextMode = TextBoxMode.MultiLine;
txt.Height = 60;
txt.Width = 300;
pn1TextBoxes.Controls.Add(txt);
} 
Literal lt = new Literal();
lt.Text = "<br/>";
pn1TextBoxes.Controls.Add(lt);
}

You'll probably want to read about ASP.NET Page Life Cycle Overview[^]

Basically the Page_PreInit() method is being called each time you click, before the click handler - so the code in the foreach loop is creating all your extra textboxes.

Put a breakpoint in the CreateTextBox and debug your code. Every time the function is called look at the stack trace and that will show you what is calling it. Alternatively put a breakpoint in all of your functions and debug your code, that will show you the order things are firing and so on and you should be able to work it out yourself from that.

How to Complete Angular/Typescript-Based Web Development Workflow in Restricted Environment

Background

Within a restricted web development environment my team has the following installed:

Visual Studio 2015 Professional (Release Version, not Update 3)
Typescript 1.6 (via default install options of Visual Studio 2015 Professional)
- Note; a later version of Typescript (3.0x) can be made available via path variable but this is the version that is integrated via Typescript installation.
Node JS 10.4 (via unzipping to directory and user PATH variable)
NPM 6.1 (via unzipping to directory and user PATH variable)
NPM Task Runner (Visual Studio 2015 extension)
Webpack Task Runner (Visual Studio 2015 extension)

With this suite of tooling I’d like to attempt at working with an existing AngularJS/ASP.NET MVC 5+ portfolio consisting of several web applications.

Problem

My team can build the ASP.NET/C#/MVC 5+ middleware and backend components just fine; the problem is that there is essentially little to no Typescript debugging/IntelliSense/etc. experience available to them.

With Typescript 1.6 built into the Visual Studio 2015 Professional IDE, said constructs do not recognize the new Typescript methods/etc. that later versions of Typescript added. Therefore, as later libraries of Angular evolved over the course of 2+ years the built-in tooling within Visual Studio has become woefully out of date.

Because of this, local front-end development is painful to the point of being extremely time consuming and error-prone. If this were just one or two files the instruction would be to look past but with hundreds of files the experience is extremely degraded and the fear is said experience would lead to poor productivity and eventual bugs/defects leaking into upper environments (staging/production) due to the poor tooling.

Challenges

The following challenges persist in this environment which makes an easy resolution path difficult:

No administrative rights on local development machines
*Any new tooling must come from stand-alone executables or configurations
Training of Existing Staff
- Any solution must be scalable such that new development teams can utilize

Current (Unsustainable) Solution

The way my team is resolving this now is via usage of remote desktop (via Windows RDP) into a specifically tailored remote server. However, said system is being decommissioned due to organizational policies. Therefore, future development must be performed via local installations.

My Current Path of Resolution

At this current point in time, I am looking into putting forward Visual Studio Code (via standalone executable and associated User-PATH variable edit) as an alternative to edit the Typescript-based files and using Visual Studio 2015 Professional for everything else. However, I know that the debugging/editing experience for this would not be ideal.

Questions

Is there a way for Visual Studio 2015 Professional to utilize a different version of Typescript for the editing experience without installing a newer version of the Typescript SDK?

If not; is there a way to disable editing of Typescript files within Visual Studio 2015?

I have tried to alter the “csproj” project files by setting the following to no avail.

XML

<TypeScriptEnabled>false</TypeScriptEnabled>
<TypeScriptCompileBlocked>true</TypeScriptCompileBlocked>

XML

<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.Default.props" Condition="True" />
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.targets" Condition="True" />

Are there any alternatives to the above worth considering?

Any advice welcome. Thank you for your time.

I use VS2017 for a Angular V6 .Net Core 2.1.2 project.
Went through many GitHub templates before I found one I liked, in which I had to heavily modify to my liking.
Try and find a template that matches your requirements, download it and use it in VS2015 and see what it does.
If I remember, VS2015 was pretty friendly with NPM, Gulp, Bower and may support TypeScript Linting and Intellisense.
I don't have enough SSD space to load VS2015 and test a copy of my project so I just have VS2017 and VS2013 for the InstallSheild.

Take a look at this
ASP.Net Core2.0, Angular6 - SPA

Guess VS2017 looks at the tsConfig.json file in the root folder of your project to load Linting and Intelisense.

You didn't tell us which line the exception was thrown from, so this is a guess.

Page_PreInit is too early. The other controls haven't been created yet, so pn1TextBoxes is null when you try to add the controls to it.

Move your control creation code to the page's Init event instead.

Accepting application/x-www-urlencode format data

I'm just learning Asp.net Web APIs. It was smooth until it's simple application/json type headers to deal with.

But now I'm trying to submit data with Content-Type:application/x-www-urlencode , but it's been really tough to get it working.

I tried different things, right from using [FromBody] attrib to "AliasBinder" etc. But nothing seem to work.

The API is dead simple , The code looks like:

class Point
{
int x {get;set;}
int y {get;set;}
}

[httpPost]
public string getValues(Point pt_in)
{

Diagnostics.Trace.TraceInfo(pt_in.x);

//Also tried using HttpUtility.Encode/Decode to read pt_in.x
}

that's it.

When I try from postman, different combo, different errors:

"Message": "The request contains an entity body but no Content-Type header. The inferred media type 'application/octet-stream' is not supported for this resource."

And at times (during various trial), I get 415 unsupported media type* error

I just need a simple Asp.net Web API example, where we are able to push Data as x-www-urlencode format & read the values inside the API.

Any help please?

thanks

MVC: Can a controller know its URL without being called?

Foothill18-Sep-18 9:22

Foothill

18-Sep-18 9:22

This is a quality of life issue I've been researching. For certain controllers I would like to add a static method or property that will contain it's absolute URL so I can make redirects a little cleaner but I cannot figure out an elegant solution.

For instance

// Instead of this in the code
return RedirectToRoute("Index", "Home");

// I would like to have
return RedirectToRoute(Controllers.HomeController.DefaultRedirect);

Is this possible?

I've been looking at routing but all the documentation that I find is limited to top layer functionality. Additionally, everything I find requires a RequestContext, a ControllerContext, or some other object that can only be known from within the controller during a web request.

One thing that I am not liking about MVC is having the code behind peppered with string literals all pointing to different controllers and actions. I like to be able to rename the Index controller to Index2 without having to hunt down 45 different places that reference the URL. Not to mention all of the other controllers that might have an Index action that just make it more difficult to find.

I suspect you're looking for T4MVC:
GitHub - T4MVC/T4MVC: T4MVC is a T4 template for ASP.NET MVC apps that creates strongly typed helpers that eliminate the use of literal strings in many places.[^]

Quote:

e.g. instead of

@Html.ActionLink("Dinner Details", "Details", "Dinners", new { id = Model.DinnerID }, null)

T4MVC lets you write:

@Html.ActionLink("Dinner Details", MVC.Dinners.Details(Model.DinnerID))

I did see that one during my searching but since it is called from within a controller, it doesn't really help me since I am looking for a static method in a controller that will generate a correct Url all the time. I did find a way to do it but it still isn't elegant as it does not provide the absolute Url like I would like.

// this is the ugly way I wrote it
[MyAuthorizationFilter]
public class HomeController : Controller
{
 public static string GetDefaultRedirectUrl(RequestContext context)
 {
   var routeValues = new RouteValueDictionary();

   routeValues.Add("area", "somearea");
   routeValues.Add("controller", "Home");
   routeValeus.Add("action", "Index");

   var urlHelper = new UrlHelper(context);
   string url = urlHelper.RouteUrl(routeValues);
 }
}

I'm still debugging my code due to tearing it apart and rewriting it dozen times trying to figure this out. I has worked but I have to fix other things before I can see if it works for what I intend it to do.

Controllers don't have urls, that is why you are struggling to do this.

What'a the URL for this action?

public class HomeController : Controller
{
        public ActionResult Index(int? id)
        {
        }
}

Is it /Home/Index/1? Is it /MyUrl/Index/1/Home?

The answer is both of them.

routes.MapRoute(
    name: "Test",
    url: "MyUrl/{action}/{id}/{controller}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

I was assuming that if the application can deduce which controller and action to route an http request to when a request is received that the reverse was also possible. I guess that it isn't possible after all.

It would appear that a controller cannot know where it's located in the website hierarchy until after it's called. Since the default routing basically follows the file system and/or namespaces I thought that there might be a way provided to backtrack up the structure to get a controller's absolute URL at runtime.

Sigh, back to peppering my controller and filter code with string literals.
