I'm using MVC 4 and Entity Framework to develop an web app. I have a table which contains persons. There is also an Edit button which invokes a modal window and thanks to it, the user can edit a person. I'm using a partial view to do so.
My question is : in my action, I return a View but I just want that when I click on the Save button, the modal window disappear and my table is updated. Any idea?
The actions :
[HttpGet]
public ActionResult EditPerson(long id)
{
var person = db.Persons.Single(p => p.Id_Person == id);
ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories, "Id_ProductPackageCategory", "Name", person.Id_ProductPackageCategory);
return PartialView("_EditPerson", person);
}
[HttpPost]
public ActionResult EditPerson(Person person)
{
ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories, "Id_ProductPackageCategory", "Name", person.Id_ProductPackageCategory);
if (ModelState.IsValid)
{
ModelStateDictionary errorDictionary = Validator.isValid(person);
if (errorDictionary.Count > 0)
{
ModelState.Merge(errorDictionary);
return View(person);
}
db.Persons.Attach(person);
db.ObjectStateManager.ChangeObjectState(person, EntityState.Modified);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(person);
}
The partial view (actually, the modal window) :
@model BuSIMaterial.Models.Person
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Edit</h3>
</div>
<div>
@using (Ajax.BeginForm("EditPerson", "Person", FormMethod.Post,
new AjaxOptions
{
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST",
UpdateTargetId = "table"
}))
{
@Html.ValidationSummary()
@Html.AntiForgeryToken()
@Html.HiddenFor(model => model.Id_Person)
<div class="modal-body">
<div class="editor-label">
First name :
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.FirstName, new { maxlength = 50 })
@Html.ValidationMessageFor(model => model.FirstName)
</div>
<div class="editor-label">
Last name :
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.LastName, new { maxlength = 50 })
@Html.ValidationMessageFor(model => model.LastName)
</div>
<div class="editor-label">
National number :
</div>
<div class="editor-field">
@Html.EditorFor(model => model.NumNat, new { maxlength = 11 })
@Html.ValidationMessageFor(model => model.NumNat)
</div>
<div class="editor-label">
Start date :
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.StartDate, new { @class = "datepicker", @Value = Model.StartDate.ToString("yyyy/MM/dd") })
@Html.ValidationMessageFor(model => model.StartDate)
</div>
<div class="editor-label">
End date :
</div>
<div class="editor-field">
@if (Model.EndDate.HasValue)
{
@Html.TextBoxFor(model => model.EndDate, new { @class = "datepicker", @Value = Model.EndDate.Value.ToString("yyyy/MM/dd") })
@Html.ValidationMessageFor(model => model.EndDate)
}
else
{
@Html.TextBoxFor(model => model.EndDate, new { @class = "datepicker" })
@Html.ValidationMessageFor(model => model.EndDate)
}
</div>
<div class="editor-label">
Distance House - Work (km) :
</div>
<div class="editor-field">
@Html.EditorFor(model => model.HouseToWorkKilometers)
@Html.ValidationMessageFor(model => model.HouseToWorkKilometers)
</div>
<div class="editor-label">
Category :
</div>
<div class="editor-field">
@Html.DropDownList("Id_ProductPackageCategory", "Choose one ...")
@Html.ValidationMessageFor(model => model.Id_ProductPackageCategory) <a href="../ProductPackageCategory/Create">
Add a new category?</a>
</div>
<div class="editor-label">
Upgrade? :
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Upgrade)
@Html.ValidationMessageFor(model => model.Upgrade)
</div>
</div>
<div class="modal-footer">
<button class="btn btn-inverse" type="submit">Save</button>
</div>
}
</div>
And my script which invokes the modal :
$(document).ready(function () {
$('.edit-person').click(function () {
var id = $(this).data("id");
var url = '/Person/EditPerson/'+id;
$.get(url, function(data) {
$('#edit-person-container').html(data);
$('#edit-person').modal('show');
});
});
});
in my action, I return a View but I just want that when I click on the Save button, the modal window disappear and my table is updated. Any idea?
Instead of returning a view from this controller action you could return a partial view containing the table. And then in the success callback of the AJAX call simply update the corresponding container.
In your POST action you could return the following:
return Json(new { error = false, message = "Person edited." });
In the AjaxOptions in Ajax.BeginForm add this:
OnSuccess = "Modal.onAjaxSuccess"
Then somewhere, say in script.js:
function onAjaxSuccess(data, status, xhr) {
if (data.error) {
$.notify({
type: "error",
text: data.message
});
}
else {
$('.modal').modal('hide');
}
}
This will close the window, but I'm still unable to get the darkened screen associated with Bootstrap modals to go away, it also won't update the DIV using AJAX - maybe Darin can shed some light?
If you're still wondering how to do this, this is how:
You have a GET action that returns the list of people:
[HttpGet]
public ActionResult People()
{
return PartialView("_ListOfPeoplePartial");
}
Then have a JS function that fires when you click save (i.e. btn-save-new-person) on the modal that allows you to create new people:
$(function () {
$(document.body).on('click', '#btn-save-new-person', function (e) {
$('#create-new-person-modal').modal('hide');
$('body').removeClass('modal-open');
$('.modal-backdrop').remove();
var url = "/Home/People";
$.get(url, function (data){
$('#list-of-people').html(data);
});
});
});
a couple of changes would need to be made but here is what I would do this case
1) change the EditPerson post method from an actionresult to a JsonResult
[HttpPost]
public JsonResult EditPerson(Person person)
{
// code here to save person
bool success = true; // somehow determine if the save was successful
string msg = ""; // error message is needed?
return JsonResult(new {success,msg, person});
}
2) Add a javascript function to close the modal
function closeModal(response){
// the response is the Json Result sent back from the action
if (response.success === true){
// actually got a true response back
}
$('#edit-person').modal('show'); // or similar code
}
3) Then Update your Ajax call to perform code on when its successful
@using (Ajax.BeginForm("EditPerson", "Person", FormMethod.Post,
new AjaxOptions
{
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST",
UpdateTargetId = "table",
OnSuccess = "closeModal(response);" // or javascript code to close the modal, you can also
}))
{ ...
a couple of tips
I don't like the MVC ajax helpers. I think they are bloated and I feel there are other frameworks better at it. Thats my opinion. To each their own though. I would prefer to use the jQuery ajax library myself. I think its easier to use but again, its up to you.
The OnSuccess means on "Server Success" not save success. so be careful.
Disclaimer: I wrote this while tired and so it might not be 100% let me know of any issues.
Good luck
