Static Binding of Dropdown list:
<p>
Will you attend?
@Html.DropDownListFor(x => x.WillAttend, new[] {
new SelectListItem() {Text = "Yes, I'll be there",
Value = bool.TrueString},
new SelectListItem() {Text = "No, I can't come",
Value = bool.FalseString}
}, "Choose an option")
</p>
Dynamic Binding of Dropdown list:
Model:
public class IndexModel
{
public IEnumerable<SelectListItem>
JobNames {get;set;}
}
Controller:
public ActionResult Index(IndexModel
model)
{
IEnumerable<SelectListItem> items = from item in edmx.JobNames
select new
SelectListItem
{
Text = item.JobName1,
Value = SqlFunctions.StringConvert((double)item.JobId)
};
model.JobNames = items;
}
Dynamic Binding of Dropdown list:
Controller:
var
DirectorsList = new List<SelectListItem>();
var DirQuery = from d in db.Directors
select d;
foreach (var d in DirQuery)
{
DirectorsList.Add(new
SelectListItem { Value = d.ID.ToString(), Text = d.Name });
}
ViewBag.Directors = DirectorsList;
View:
@Html.DropDownListFor(model
=> model.Director, ViewBag.Directors as List<SelectListItem>,
"All")
Static Binding of
Radiobuttonlist
View:
@model Account
@{
ViewBag.Title = "Create Account";
}
@using (
Html.BeginForm() )
{
<div>
<span>Do you agree to the Terms
and Conditions?</span>
<br />
@Html.RadioButtonFor( model => model.TermsAndConditions,
true, new { id = "TermsAndConditions_true" } )
<label
for="TermsAndConditions_true">Yes</label>
<br />
@Html.RadioButtonFor( model =>
model.TermsAndConditions, false, new { id =
"TermsAndConditions_false" } )
<label
for="TermsAndConditions_false">No</label>
<br />
@Html.ValidationMessage(
"TermsAndConditionsAgreement" )
</div>
<div>
<input id="CreateAccount"
type="submit" name="submit" value="Create
Account" />
</div>
}
Model:
public class
Account
{
public bool TermsAndConditions { get; set;
}
//other properties here.
}
Controller:
public
ActionResult CreateAccount()
{
//this default instance will be used to
pre-populate the form, making the "No" radio button checked.
var account = new Account
{
TermsAndConditions = false
};
return View( account );
}
//This handles
the POST request.
[HttpPost]
public
ActionResult CreateAccount( Account account )
{
if ( account.TermsAndConditions )
{
//TODO: Other validation, and create
the account.
return RedirectToAction(
"Welcome" );
}
else
{
ModelState.AddModelError(
"TermsAndConditionsAgreement", "You must agree to the Terms and
Conditions." );
return View( account );
}
}
public
ActionResult Welcome()
{
return View();
}
label
element with the for
attribute set to the IDs of the each radio button. This lets users click on the
label to select the radio button instead of having to click on the radio button
itself. This is standard HTML. For this to work I had to set manual IDs on the
radio buttons, otherwise they would both get the same ID of just
"TermsAndConditions", which wouldn't work.1.var account = new Account
{
TermsAndConditions = false
};
2. Account
obj=new Account();
obj. TermsAndConditions=false;
3. public ActionResult SomeForm()
{
return View(new SomeModel { TermsAndConditions = false });
}
Selecting Radiobutton by default
@Html.RadioButtonFor(model
=> model.TermsAndConditions, "False", new { Checked =
"checked" })
Note: All is ok if the user completes
the form without any errors. However, if
I do server side validation and the page is refreshed, I lose the selection that the user made for
the radio button and the selected radio
goes back to the default false field.
