Custom Login page retrieve null data C#

I have Login page which Customer should login with their Email adresse ,But when i write email adresse and hit button , its just redirected me to the same page i was before (Login) and than i debugge the code and its retrieve all null.Can anyone direct me in the right direction? thx

According to your debugging screen shot, your ED_data_A_S_Customer model has a property called E_Mail. But the form element you're using is named Email. These names are different. As a result, the ASP.NET MVC Framework's model binder has no way to know where to get the E_Mail value.
Change your form element to match your model:
<input style="color:black;" id="Email" name="E_Mail" value="" required="" type="email" placeholder="Kunde ID ..." class="input">
<!-- ^here -->
Since you're only using a single value, you could also just as easily not use the model at all and just use that single value:
public ActionResult Login(string e_mail)
(Name it whatever you like, just make sure the form element's name matches.)
Of course, it's also worth noting here that a login which has only a username and no password is terribly insecure.

Send Ajax Requests vs Sending Entire Form By Id

The client should be able to send everything with a button, so I can do the following:
Send everything as form fields named like invoiceId_detail_text where invoiceId would be the id of the invoice, detail the part, and text the kind of field.
Example:
<form id="invoices" name="invoice">
#foreach(var Invoce in Model.Invoices) {
<div>
<input type="number" id="#String.Format("{0}_amount", Invoice.InvoiceId)"/>
</div>
/*More Input Fields for the Invoice*/
<div>
<button type="submit"></button>
</div>
}
</form>
Or I can put every invoice separated in its own form, and send them by ajax, every form success I send the next one and so on.
Example:
#foreach(var Invoice in Model.Invoices) {
string formName = String.Format("{0}_form", Invoce.InvoceId);
<form id="#formName" class="invoiceForm" id="#formName" action="#Url.Action("EditIndividualInvoice","InvoicingEdit")">
<input type="hidden" name="InvoiceId" value="#Invoice.InvoiceId"/>
<div>
<input type="number"/>
</div>
/*More Input Fields for the Invoice*/
</form>
}
<button type="button" onclick="SendAllForms();">Send</button>
I did some research between some of my co-workers and many of them told me to just go with a post with all the invoices at the same time and then access every field by item id because I don't have knowledge of how many invoices are going to be sent, but i can get all of them by class on JQuery so it shouldn't be a problem.
I also read this article from a UX point of view and it keeps me thinking about it.
By doing it with AJAX the cliend could be able to see a loading bar and it would be great, but if he closes the page the request would be incomplete and it could be complicated.
Which option could be better and why and what are the security implications of using one over another?

I think the solution depends principally of the behavior that you wish.
By doing it with AJAX the cliend could be able to see a loading bar and it would be great, but if he closes the page the request would be incomplete and it could be complicated.
In the 2 solutions, if the user closes the page after clicking the button, this will not cancel the save. Once the request sent, it cannot be cancelled. So you shouldn't have "security" problems whatever the choosen solution.
The only thing you need to be careful, is to disable all AJAX buttons during an AJAX request, to avoid the user sending several request in the same time (that can provoke saving inconsistency data).
The classic solution is generally most simple to implement.
The AJAX solution can be most complicated to implement (more code), but provides a friendliest behavior.

Username and Passowrd Textboxes automatically get's filled with the data after login

I am having a little problem. Whenever i login and set Remember password option to yes, the next page contains a form and it also includes username and password textboxes. They automatically get filled with the same username and password. Why is this happening? Please Tell me how to solve it

Its browser property. To stop this you can set autocomplete="off" in your inupt type.
<input type="text" name="Username" autocomplete="off">
and AutoCompleteType="disable" when using asp:TextBoxes
You can also put this on the form tag. Note this does not work consistently in all browsers.

I'm part of a project that requires auto-complete or auto-suggest feature for postal addresses (something similar to what google maps has). As the user starts to type in the number and then the street google starts to suggest valid options. I would like to know if there is an api (even commercial) available in the market.
Note: I'm not looking for an address validation API.
I could also buy a address database and implement this on top of it. But thats a lot of Dev overhead involved if we need to build something robust and sophisticated. Any good pointers will help.
Thanks

This looks to give you a solution similar to the one you are searching for. If you replace the on_click event with the Javascript onkeyup you should then be able to check the address realtime.
This is a quick step-by-step integration guide describing how to add a RapidAddress postcode based address finder to a HTML website. We recommend you read the JavaScript user guide first.
Step #1
Download the latest version of the JavaScript class from the downloads section. You could also use the integration pack, it contains ready made HTML pages that may be handy as a starting point.
Upload the JavaScript file crafty_postcode.class.js to your webserver and reference it in your HTML, you may have to use relative or absolute paths in the src property:
<script type="text/javascript" charset="ISO-8859-1" src="crafty_postcode.class.js">
</script>
NOTE: the "ISO-8859-1" bit is important as the JS script is compressed.
Step #2
Create and configure the JavaScript object:
<script>
var cp_obj = CraftyPostcodeCreate();
cp_obj.set("access_token", "xxxxx-xxxxx-xxxxx-xxxxx"); // your token here
cp_obj.set("result_elem_id", "crafty_postcode_result_display");
cp_obj.set("form", "address");
cp_obj.set("elem_company" , "companyname");
cp_obj.set("elem_street1" , "address1");
cp_obj.set("elem_street2" , "address2");
cp_obj.set("elem_street3" , "address3");
cp_obj.set("elem_town" , "town");
cp_obj.set("elem_county" , "county");
cp_obj.set("elem_postcode" , "postcode");
</script>
Step #3
Create an address form in HTML:
<form method="post" name="address">
Postcode:<br/>
<input type="text" name="postcode"/>
<button type="button" onclick="cp_obj.doLookup()">Find Address</button><br/>
<span id="crafty_postcode_result_display"> </span><br/>
Company:<br/>
<input type="text" name="companyname"/><br/>
Address:<br/>
<input type="text" name="address1"/><br/>
<input type="text" name="address2"/><br/>
<input type="text" name="address3"/><br/>
Town:<br/>
<input type="text" name="town"/><br/>
County:<br/>
<input type="text" name="county"/>
</form>
NOTE: "companyname", "address2/3" and "county" are optional, you can leave these fields out if it suits your site. Remember to delete also them from the JavaScript config in step 2. For example if you do not want the county field : cp_obj.set("elem_county", "");
Note the 'Find Address' button, the onclick action calls the doLookup() method.
The address results (or an error message) will be placed in the element with id="crafty_postcode_result_display".
All done!
If things don't work for any reason, email any error codes/messages to us. We will be happy to help. You may also want to read the JavaScript user guide, if you haven't already.
As found at:
http://www.craftyclicks.co.uk/web-service/docs/javascript-address-finder-how-to-add-rapidaddress

You can use googles geo autocomplete api
http://code.google.com/p/geo-autocomplete/
This will give you the same auto-complete for locations that you would get on googlemaps.

What does the Request object do in the following scenario?

If I see something like:
if(Request["Email"])
{
}
What does this actually mean? Where is the Email collection member actually being set?

It's retrieving the variable from get/post parameters.
somepage.aspx?blah=1
string blahValue = Request["blah"];
Console.WriteLine(blahValue);
> 1
Even more specificially:
Cookies, Form, QueryString or ServerVariables
http://msdn.microsoft.com/en-us/library/system.web.httprequest_members(VS.71).aspx

See this for example.
Taken from the above link
All variables can be accessed directly by calling Request(variable) without the collection name. In this case, the Web server searches the collections in the following order:
QueryString
Form
Cookies
ClientCertificate
ServerVariables

It retrieves either the submited form values (POST) or the submitted querystring values (GET).
You would generally see it written as either Request.Form["Email"] or Request.Querystring[Email"] instead of just Request["Email"].
Example of Form (POST) method:
On the HTML or ASPX Page:
<form action="SomePage.aspx">
<input type="hidden" name="Email" value="someaddress#email.com" />
<input type="Submit" value="Submit Form" />
</form>
Once the form has been submitted by clicking the Submit Form button you would retrieve the form values using Request.Form["Email"] (or just Request["Email"] for the lazy :))

Just some additions to the posts of the others.
To have things more explicitly you normally use Request.QueryString[...] for getting values from the QueryString, so when a GET request has been done and Request.Form[...] when a POST request is done. Although in the latter case you usually directly access the values of your server controls, since ASP.net uses the ViewState mechanism to load back on your controls when the request comes back from the client.
