Inline editing of Webgrid row in MVC3 - asp.net-mvc-3

Question

public class UserDetailsModel
{
public int ID { get; set; }
public string LoginID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string IsDeleted { get; set; }
public DateTime CreatedOn { get; set; }
}
Controller:
public ActionResult Index()
{
object model = obj.getUserList();
return View(model);
}
public ActionResult Delete(int id)
{
BAL_obj.deleteUser(id);
object model = obj.getUserList();
return View("Index",model);
}
Index.cshtml:
#model IEnumerable<WebGrid1App.Models.UserDetailsModel>
#{
WebGrid grid = new WebGrid(Model);
}
<h2>People</h2>
#grid.GetHtml(
headerStyle: "headerStyle",
tableStyle: "tableStyle",
alternatingRowStyle: "alternateStyle",
fillEmptyRows: true,
mode: WebGridPagerModes.All,
firstText: "<< First",
previousText: "< Prev",
nextText: "Next >",
lastText: "Last >>",
columns: new [] {
grid.Column("ID",header: "ID"),
grid.Column("LoginId",header:"LoginID"),
grid.Column("FirstName", canSort: false),
grid.Column("LastName"),
grid.Column("CreatedOn",
header: "CreatedOn",
format: p=>p.CreatedOn.ToShortDateString()
),
grid.Column("",
header: "Actions",
format: #<text>
#Html.ActionLink("Edit", "Edit", new { id=item.ID} )
|
#Html.ActionLink("Delete", "Delete", new { id=item.ID} )
</text>
)
})
I have done with the delete operation.
How can I edit a row on same page and save the changes into database?
There will edit button. When you click on it, row will be editable.
Meanwhile edit link text is changed as Save link.
Now when you click on Save, row needs to be updated.
I want to do Inline editing.
Can you please help me out with this?

Answer 1

You could use AJAX. Start by wrapping the webGrid into an html form which will allow for editing the record:
#using (Html.BeginForm("Update", null, FormMethod.Post, new { #class = "updateForm" }))
{
#grid.GetHtml(
headerStyle: "headerStyle",
tableStyle: "tableStyle",
alternatingRowStyle: "alternateStyle",
fillEmptyRows: true,
mode: WebGridPagerModes.All,
firstText: "<< First",
previousText: "< Prev",
nextText: "Next >",
lastText: "Last >>",
columns: new[]
{
grid.Column("ID",header: "ID"),
grid.Column("LoginId",header:"LoginID"),
grid.Column("FirstName", canSort: false),
grid.Column("LastName"),
grid.Column("CreatedOn",
header: "CreatedOn",
format: p=>p.CreatedOn.ToShortDateString()
),
grid.Column("",
header: "Actions",
format: #<text>
#Html.ActionLink("Edit", "Edit", new { id = item.ID }, new { #class = "edit" })
|
#Html.ActionLink("Delete", "Delete", new { id = item.ID })
</text>
)
}
)
}
Then you could have 2 partials, one for editing and one for displaying a single record.
EditUserDetailsModel.cshtml:
#model UserDetailsModel
<td>#Html.EditorFor(x => x.ID)</td>
<td>#Html.EditorFor(x => x.LoginID)</td>
<td>#Html.EditorFor(x => x.FirstName)</td>
<td>#Html.EditorFor(x => x.LastName)</td>
<td>#Html.EditorFor(x => x.CreatedOn)</td>
<td>
<button type="submit">Update</button>
</td>
DisplayUserDetailsModel:
#model UserDetailsModel
<td>#Html.DisplayFor(x => x.ID)</td>
<td>#Html.DisplayFor(x => x.LoginID)</td>
<td>#Html.DisplayFor(x => x.FirstName)</td>
<td>#Html.DisplayFor(x => x.LastName)</td>
<td>#Html.DisplayFor(x => x.CreatedOn)</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id = Model.ID }, new { #class = "edit" })
|
#Html.ActionLink("Delete", "Delete", new { id = Model.ID })
</td>
and then we could have the corresponding controller actions:
public ActionResult Edit(int id)
{
UserDetailsModel model = repository.Get(id);
return PartialView("EditUserDetailsModel", model);
}
[HttpPost]
public ActionResult Update(UserDetailsModel model)
{
repository.Update(model);
return PartialView("DisplayUserDetailsModel", model);
}
and finally the javascript to make this alive:
$('table').on('click', '.edit', function () {
$.ajax({
url: this.href,
type: 'GET',
cache: false,
context: $(this).closest('tr'),
success: function (result) {
$(this).html(result);
}
});
return false;
});
$('.updateForm').on('submit', function () {
$.ajax({
url: this.action,
type: this.method,
data: $(this).serialize(),
context: $('input', this).closest('tr'),
success: function (result) {
$(this).html(result);
}
});
return false;
});

Answer 2

The answer using ajax works fine - but you have to be aware that here multiple lines can be simultaneuously in edit mode.
A solution allowing only editing of one line (with less ajax requests) is:
