#Html.TextBoxFor(m=>m.FirstName) <br/>
<label> From country:</label>
#Html.DropDownListFor(m=>m.CountryId, Model.Countries,"--please select-- ") <br/>
<input id="btnSave" value ="Login" type="submit" name="commandName"/>
<input id="btnRegister" value ="Register" type="submit" name="commandName"/>
}
}
[HttpPost]
public ActionResult Create(StudentModel studentModel, string commandName)
{
if(commandName == "Login")
{
}
else if(commandName == "Register")
{
}
return View("Index");
}
after reading his answer some confusion occur in my mind because i am newbie in mvc and those are as follows
first of all ur code is not readable for ill format. i am new in mvc....just learning it. after reading ur code some confusion occur.
1) why extra bracket u gave #{ }
2 u use <label> Name</label> in form building code. in html4 is there any tag ? is it html5 specific tag ?
3) #Html.DropDownListFor(m=>m.CountryId, Model.Countries,"--please select-- ")
when u building dropdown why u did not specify value & text filed.......how mvc can understand what field will be value & what will be text ? u just bind the model with DropDownListFor()
4) just see it
<input id="btnSave" value ="Login" type="submit" name="commandName"/>
<input id="btnRegister" value ="Register" type="submit" name="commandName"/>
both the button name is commandName ? is it correct ?
when user click on any button then how button name will be pass to
public ActionResult Create(StudentModel studentModel, string commandName)
Create() method ? please tell me how implicitly command name will be pass to Create() and how commandName variable at server side can hold the button name.
i have too much confusion after reading ur code. if possible please discuss all my points in details. thanks

Answer 1

i want that when user click on login button then i will submit form
through jquery but before submit i will change action url. the same
way i want to call register action method when user click on register
button.
1. Event on button click:
$(function(){
$("#btnSave").click(function(){
$("#btnSave").closest("form").attr("action", "/home/test");
});
});
2. MarkUp:
<form method="POST" action="/home/test1" >
<input id="btnSave" value="Login" type="submit" name="commandName"/>
</form>
3. Server side:
[HttpPost]
public ActionResult Test(string commandName)
{
return null;
}
1) Razor syntax reference http://haacked.com/archive/2011/01/06/razor-syntax-quick-reference.aspx
2) The <label> is not specific html5 tag but it have additional attribute in html5, http://www.w3schools.com/tags/tag_label.asp
3) You can build your IEnumerable of SelectListItem in which specified Text and Value
4) The input name commandName is not important if you don't want to catch client value value ="Login" on server side,
