MVC - Related Data - Postback
Jan 13 2015 11:17 AM
Hi all,
I have an MVC 5 generated "Create" page. Now for the related data I have made a table, which looks like this:
When clicking on the green add button, the following modal is shown:
In this design, the user is able to add/remove sub-items to the list before submitting the form.
In this example, the row in the screenshot I add initially. All works well, except when I remove this initial row in my Create action (which shouldn't be there anyway, it should start with an empty table) no rows added are available on the server. Somehow, the Model Binder only works when there's initially 1 row rendered from the create action.
Data Model:
Controller actions:
(
OrganisatieController.cs
)
public
ActionResult
Create()
{
Organisatie
myOrganisatie =
new
Organisatie
();
//-- Test Data --
AccountType_Organisatie
myAccTypeOrg =
new
AccountType_Organisatie
();
myAccTypeOrg.Accounttype_GUID = csContext.AccountTypes.First().AccountType_GUID;
myAccTypeOrg.AccountType = csContext.AccountTypes.First();
myAccTypeOrg.Omschrijving =
"Test1234"
;
myOrganisatie.AccountType_Organisaties.Add(myAccTypeOrg);
//-- End Test Data –
//-- Load Dropdown Data --
ViewBag.slAccountTypes =
new
SelectList
(csContext.AccountTypes,
"AccountType_GUID"
,
Omschrijving"
);
return
View(myOrganisatie);
