While populating a ComboBoxFor to be inside a grid, if the name of the view data variable is the same as the id, validation will be ignored.
View:
columns.ForeignKey(p => p.JobNo, (System.Collections.IEnumerable)ViewData[
"JobNo"
],
"JobNo"
,
"JobNumber"
);
Controller:
public
IActionResult Index()
{
ViewData[
"jobnumber"
] = _ddservice.GetAllOrdersByOfficeIdDD(oid);
return
View();
}
