Following this MVC Tutorial, but cannot get the display customer view to display after input the data. I don't see anything I do wrong
http://www.codeproject.com/Articles/207797/Learn-MVC-Model-View-Controller-step-by-step-in-7
here is my fill customer
<div>
<form action="DisplayCustomer.aspx" method="post">
Enter Customer Code: <input type="text" name="CustomerCode" /><br />
Enter Customer Name: <input type="text" name="CustomerName" /><br />
Ennter Customer Amout: <input type="text" name="CustomerAmount" /><br />
<input type="submit" value="Submit customer data" />
</form>
</div>
here is my display customer
public ActionResult DisplayCustomer()
{
Customer localCustomer = new Customer();
localCustomer.Code = Request.Form["CustomerCode"].ToString();
localCustomer.Name = Request.Form["CustomerName"].ToString();
localCustomer.Amount = Convert.ToDouble(Request.Form["CustomerAmount"].ToString());
return View(localCustomer);
}
then
<div>
The name of the customer is: <%:Model.Name = "test" %>
<br />
The code of the customer is: <%:Model.Code %>
<br />
The amout refund to the customer is: <%:Model.Amount%>
</div>
seems like something is wrong with the steps
I got this error when I tried
Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested URL: /customer/DisplayCustomer.aspx
Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.17929
The correct path for the request is /customer/displaycustomer
The .aspx extension gets handled in a different way, so the MVC Routing Engine is never fired, and as that page doesn't exist at that path the result is a 404 error.
You actually need to remove .aspx extension. Just request the page as /Customer/DisplayCustomer.
As a side note, you may need to update your form aswell and remove the aspx extension, eg:
<form action="DisplayCustomer" method="post">
Enter customer id :- <input type="text" name="Id" /> <br />
Enter customer code :- <input type="text" name="CustomerCode" /><br />
Enter customer Amount :-<input type="text" name="Amount" /><br />
<input type="submit" value="Submit customer data" />
</form>
replaced the line:
<form action="DisplayCustomer.aspx" method="post">
to
<form action="DisplayCustomer" method="post">

I'm writing an MVC website in C# with razor syntax.
I have some code here:
#using (Html.BeginForm("DoSignUp", "SignUpController", FormMethod.Post))
{
<input type="text" width="3000" value="" name="Name" />
<input type="submit" value="Register" /
}
So this form should post to the SignUpController on the DoSignUp method. Instead of doing that it just posts back to the page I'm currently on which is called SignUp. I suspected there might be something wrong with my routing but when I look at the html that is being generated through the browser developer tools i see this:
<form action="" method="post">
<input type="text" width="3000" value="" name="selectedURL">
<input type="submit" value="Register">
</form>
Edit: Well I wrote this out and then looked at my code again. The problem which I keep bloody doing is that SignUpController should just be SignUp.
Remove the 'Controller' from your controller name (SignUp, not SignUpController). It's assumed to be a controller by convention
#using (Html.BeginForm("DoSignUp", "SignUp", FormMethod.Post))
{
<input type="text" width="3000" value="" name="Name" />
<input type="submit" value="Register" /
}
I have this form and I want it to connect to an external database. I have no idea how to and after a lot of research its still not clear to me.
Here is my code. Any guidance will be helpful.
#{
ViewData["Title"] = "Index";
}
<h2>User Information</h2>
<p>This is your user information!</p>
<form action="Result">
First name:<br>
<input type="text" name="firstname" value=" ">
<br>
Last name:<br>
<input type="text" name="lastname" value=" ">
<br>
Role:<br>
<input type="text" name="Role" value=" ">
<br>
Ranking:<br>
<input type="text" name="Ranking" value=" ">
<br><br>
<input type="submit" value="Save">
</form>
I don't really know which direction to take this form. Many thanks in advance
You don't connect the actual form itself, you connect your backend to the DB, and you connect the form to your backend.
Make some sort of route to handle the form request and then connect to your database in that route, and use it to input the data to the database.

Your form should post data to an existing action inside an existing controller, and then, your database db connection already must be defined in your server-side MVC application.
At your point, probably, your form is looking for something called "Result"...
Now, I think that you are able to keep your research for solutions to your specific case.
I am doing my first ASP.NET mvc project, on the home page, Index.cshtml, I have a small form:
<form action="ChoixFormulaire" method="get">
<fieldset>
<label>NAS</label>
<input id="nas" type="text" placeholder="###"/>
<br />
<label>Date of birth</label>
<input id="date" type="text" placeholder="AAAA-MM-JJ"/>
<br />
<label>Employee number</label>
<input id="numEmployee" type="text" placeholder="######"/>
<br />
</fieldset>
<input type="submit" value="Soumettre" onclick="return VerifierFormulaire()" />
</form>
When the button is clicked, there is some verification made in the 'VerifierFormulaire()' method, which is defined in the same Index.cshtml file. Then the ChoixFormulaire.cshtml is displayed (called from the ChoixFormulaire() method in my HomeController, which returns View()).
I was expecting the form inputs to be in the URL as parameters. For example, If I enter '123' for NAS, '1989-01-01' for date of birth and '123456' for employee number, I am redirected to http://localhost:15778/Home/ChoixFormulaire? but I would expect to be redirected to http://localhost:15778/Home/ChoixFormulaire?nas=123&dateBirth=1989-01-01&numEmployee=123456
Try adding the name attribute:
<input id="nas" name="nas" />
MVC3 non-sequential index hidden inputs for model binding..
<input type="hidden" name="Index" value="whatever" />
Does it matter if they go before, after, in the middle of the other related inputs to be posted?
Does it matter at all where they end up in the posted data?
For example, can they all be lumped together and it still works?
<input type="text" name="[A].Id" value="1" />
<input type="text" name="[B].Id" value="2" />
<input type="hidden" name="Index" value="A" />
<input type="hidden" name="Index" value="B" />
No, the order of your form fields does not matter, nore where they appear on the html page.
The most important factor for MVC3 is the name of the fields must match to the name of your controller/action parameter.
If you have two fields with the same name however, only one value will be returned into your action.
As long as the hidden fields are located inside of the form it should not matter the order in which they are placed. Please see code sample below. Notice how the hidden fields are put anywhere inside of the form.
#using (Html.BeginForm())
{
#Html.ValidationSummary(false, "Please correct the following errors")
#Html.HiddenFor(m => m.CoolStuffId)
#Html.Partial("_EditCoolStuff", Model)
<fieldset class="ui-grid-a">
<div class="ui-block-a"><a data-role="button" href="#Url.Action("ActionPlan", "Store", new { id = Model.StoreID })">Cancel</a></div>
<div class="ui-block-b"><button type="submit" data-theme="a">Submit</button></div>
</fieldset>
#Html.HiddenFor(m => m.TypeId)
}
This is my markup:
<form action="/Customer/Create" enctype="multipart/form-data" method="post">
<input id="file" type="file" style="width:300px" />
<input type="submit" id="btnSubmit" value="Add Image to S3" />
</form>
When I step through the Create action the Request.Files is empty. I've searched and searched and all the advice seems to be about ensuring the enctype is set to "multipart/form-data" which I have already set. Any other ideas?
Try adding a name attribute to the input. I don't think nameless form items get posted at all.
