Hi all,

I found many posts here and there about this error, but none seemed to fit my scenario.
My grid is fairly simple, almost like the one form the sample app. I renamed my columns and added a column template to display "Edit" and "Details" links, and having to add a "Render()" action.

Now anytime a want to use AJAX (filtering, paging, refreshing), I get an "Error! The requested URL returned 500 - error"
Further investigation with FireBug tells me that the server returnd this:

The partial view '_Index' was not found. The following locations were searched:

~/Views/InternalProposal/_Index.aspx

~/Views/InternalProposal/_Index.ascx

~/Views/Shared/_Index.aspx

~/Views/Shared/_Index.ascx

and so on...

I am totaly lost. I suspect the added "render()" action to mess things up..

This is my view:

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

<h2>

Internal Proposal</h2>

<% if (Model.Count() == 0)

{%>

DB empty

<%

}

else

{%>

<% Html.Telerik().Grid(Model)

.Name("Grid")

.Columns(columns =>

{

columns.Bound(o => o.caseID).Title("#Case").Width(80);

columns.Bound(o => o.status).Title("Status");

columns.Bound(o => o.id_agree).Title("#Agree");

columns.Bound(o => o.date_reg).Format("{0:dd/MM/yyyy}").Width(80).Title("Registration Date");

columns.Bound(o => o.car_vin_no).Width(160).Title("VIN");

columns.Bound(o => o.date_reply).Format("{0:dd/MM/yyyy}").Width(80).Title("Reply date");

columns.Bound(o => o.user_reply).Title("User Reply");

columns.Template(o =>

{%>

<%=Html.ActionLink("Edit", "Edit", new {id = o.id_main})%>

|

<%=Html.ActionLink("Details", "Details", new {id = o.id_main})%>

<%})

.ClientTemplate("<a href='" + Url.Action("Edit", "InternalProposal") + "/<# id_main #>Edit</a>" +

" | <a href='" + Url.Action("Details", "InternalProposal") + "/<# id_main #>Details</a>").Title(

"").Width(100);

})

.DataBinding(dataBinding =>

{

dataBinding.Server().Select("Index", "InternalProposal", new { ajax =

ViewData["ajax"] });

dataBinding.Ajax().Select("_Index", "InternalProposal").Enabled((bool)ViewData["ajax"]);

})

.Scrollable(scrolling => scrolling.Enabled((bool)ViewData["scrolling"]))

.Sortable(sorting => sorting.Enabled((bool)ViewData["sorting"]))

.Pageable(paging => paging.Enabled((bool)ViewData["paging"]))

.Filterable(filtering => filtering.Enabled((bool)ViewData["filtering"]))

.Groupable(grouping => grouping.Enabled((bool)ViewData["grouping"]))

.Footer((bool)ViewData["showFooter"])

.Render();%>

<%}%>

<br />

<p>

<%: Html.ActionLink("Add Proposal", "Create") %>

</p>

</asp:Content>

This is my controller:

public ActionResult Index(bool? ajax, bool? scrolling, bool? paging, bool? filtering, bool? sorting,

bool? grouping, bool? showFooter)

{

ViewData["ajax"] = ajax ?? true;

ViewData["scrolling"] = scrolling ?? true;

ViewData["paging"] = paging ?? true;

ViewData["filtering"] = filtering ?? true;

ViewData["grouping"] = grouping ?? true;

ViewData["sorting"] = sorting ?? true;

ViewData["showFooter"] = showFooter ?? true;

var viewModel = new InternalProposalHeader[] { };

viewModel = GetIntenalProposalHeaders(providerID); //ProviderID - from session info

return View(viewModel);

}

//Action for Telerik Grid AJAX

[GridAction]

public ActionResult _Index()

{

var viewModel = new InternalProposalHeader[] { };

viewModel = GetIntenalProposalHeaders(providerID); //ProviderID - from session info

return PartialView(viewModel);

}

Hi Atanas!

While prepering the sample project a found the bug.
The problem was within the "ClientTemplate" parameter - a link for ajax. I mixed things up around inside there.
Was:

.ClientTemplate("<a href='"
+ Url.Action("Edit", "InternalProposal"

) 

	+

"/<# id_main #>Edit</a>"
+ " | <a href='"
+ Url.Action("Details", "InternalProposal"

) 

	+

"/<# id_main #>Details</a>");

Should be

.ClientTemplate("<a href='"
+ Url.Action("Edit", "InternalProposal"

) 

+

"/<#=id_main#>'>Edit</a> "
+ "| <a href='"
+ Url.Action("Details", "InternalProposal"

) 

+

"/<#=id_main#>'>Details</a>")

Thank you

Best Regards,
Szymon
