DataSourceURL doesn't seem to work for me for a Combo in a grid
posted

Hello-

I'm struggling a little bit with the grid.  I have it all working fairly nicely and now I want to put some dropdowns in.  The samples all seem to use options.DataSource([object]) and not .DataSourceUrl.  When I use DataSourceUrl, I can see the Controller method being called.

The difficulty I'm having is that no matter what I return, the dropdown is empty.  I used the same Controller pattern as the DataSourceUrl for the Grid:

[GridDataSourceAction]
public ActionResult GetAccounts()
{
    using (var cont = new Models.MyDBEntities())
    {
         var accts = cont.accounts.Select(acct => new { AccountCode = acct.AccountCode, AccountName = acct.AccountName }).ToList();
         return View(accts.AsQueryable());

     }
}

But no matter what I return (whether it's IQueryable<T> or not), nothing winds up in the dropdown.

    Hi efanstay

    i solved this problem many time ago, this is the code of my combo():

    @(Html.Infragistics()
    .ComboFor(model => model.idEstado)
    .ID("ddEstados")
    .EnableClearButton(false)
    .DropDownButtonTitle("Estados")
    .Mode(ComboMode.DropDown)
    .TextKey("Nombre")
    .ValueKey("idEstado")
    .Width("210px")
    .DataSource(@Url.Action("GetEstados"))
    .DataBind()
    .Render())

    and my controller action look like this:

    [AcceptVerbs(HttpVerbs.Get)]
    public ActionResult GetEstados()
    {
     LargeJsonResult DataView = new LargeJsonResult() { JsonRequestBehavior = JsonRequestBehavior.AllowGet };
      DataView.Data = from p in da.Estados
       orderby p.Nombre
       select p;
      return DataView;
    }

    really i hope this can help you.

    Regards.

    Hi,

    Can you try using [ComboDataSourceAction] attribute instead of [GridDataSourceAction] for GetAccounts method that you are using as DataSourceUrl for Combo?
