Unterminated string error due to foreign key string containing single quote

I'm attempting to use a foreign key column and I sometimes get an unterminated string error while loading the page. I determined that this is due to having a single quote in the data (not uncommon for users to do that).

This is easy to duplicate using the MVC Example project by simply changing an Employee name in the Northwind database to contain a single quote. The Grid Foreign Key demo will show the error. (BTW, Firefox doesn't really indicate the error, it just stops. IE blows up.)

Encoding the string doesn't help. The resulting data simply shows the ' value in the output.

Anyone else have a similar problem?

issues with populating a grid only after user input

I have a pretty basic grid that is not populated on load. It requires users to enter search criteria first, which then searches the database and populates the grid. Below is the grid code

Html.Kendo().Grid<ArrayOfSearchResultObjectSearchResultObject>(Model.Results)

.Name("srchGrd")

.Columns(columns =>

{

columns.Bound(o => o.Chemical).ClientTemplate("<a title='#=Chemical#' href=

'" + Url.Action("", "ChemBioSearch", new { area = "Tools" }, Request.Url.Scheme) + "/GetDetail?ChemName=#=Chemical#&DetailID=#=ID#&DetailSource=#=SearchSource#&id=" + Model.ProjectGUID.ToString() + "'

>" +

"#=Chemical# </a>"

).Title("Chemical");

columns.Bound(o => o.CasNumber).Title("CAS #");

columns.Bound(o => o.UnNumber).Title("UN ID #");

columns.Bound(o => o.FriendlySourceName).Title("Data Source");

})

.DataSource(ds =>

{

ds.Ajax().ServerOperation(false).Read(read => read.Action("_GetSearchResults", "ChemBioSearch", new { area = "Tools" }));

}

)

.Scrollable(scrolling => scrolling.Enabled(false))

.Sortable(sorting => sorting.Enabled(true))

.Pageable(paging => paging.Enabled(true))

.Filterable(filtering => filtering.Enabled(true))

.Groupable(grouping => grouping.Enabled(false))

.Render();

which used to work great but broke ever since i upgraded to the Kendo 924 version (and same problem since the 1002 as well) it doesn't work like it used to.

Basically i have 2 controller methods. The first (SearchChemBio) gets called when the user enters the search data and hits enter. data gets sent no problem and send a partialresult (which contains the grid). I have the ajax call in there in order to handle sorting/filtering/paging.

[AcceptVerbs(HttpVerbs.Post | HttpVerbs.Get)]

[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]

public ActionResult _GetSearchResults([DataSourceRequest] DataSourceRequest request,ChemBioSearchModel mdl)

{

if ((mdl != null) && (mdl.IsValid))

{

ArrayOfSearchResultObject rslt = SearchGlobal(mdl);

if ((rslt != null) && (rslt.Items.Length > 0))

{

foreach (ArrayOfSearchResultObjectSearchResultObject arr in rslt.Items)

{

mdl.Results.Add(arr);

}

return Json(mdl.Results.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);

}

return Json(new List<ArrayOfSearchResultObjectSearchResultObject>().ToDataSourceResult(request), JsonRequestBehavior.AllowGet);

}

[HttpPost]

[ValidateAntiForgeryToken]

public ActionResult SearchChemBio(ChemBioSearchModel mdl)

{

if (mdl != null)

{

if (ModelState.IsValid)

{

ArrayOfSearchResultObject rslt = SearchGlobal(mdl);

if ((rslt != null) && (rslt.Items !=null) && (rslt.Items.Length > 0))

{

foreach (ArrayOfSearchResultObjectSearchResultObject arr in rslt.Items)

{

mdl.Results.Add(arr);

}

return PartialView("SearchResults", mdl);

}

else

{

return View(mdl);

}

throw new ArgumentException("No Model found for Chem Bio Search");

}

unfortunately now, the model in the Ajax call (_GetSearchResults) is always blank now (it didn't used to be before the update). Is there something i'm missing? I feel like i'm doing double work here, but can't figure out how to marry both calls.

TreeView not expanding on mobile

TreeView is not expanding on mobile devices (well, at least on iOS and Android):
ver 2012.2.913
styles and scripts in order:
kendo.common.min.css
kendo.default.min.css"
kendo.mobile.all.min.css

jquery-1.7.1.min.js
kendo.all.min.js
kendo.aspnetmvc.min.js

not expanding example:
@(Html.Kendo().TreeView()
.Name("sometree")
.Items(treeview =>
{
treeview.Add()
.Expanded(false)
.Selected(true)
.Items(items =>
{
items.Add().Text("S");
items.Add().Text("S");
items.Add().Text("S");
});
})
)

[Solved] Grid row iteration of a single page

Hi

Is there any way I can loop through the rows for a particular page or at least the page visible to the user.
What am I doing right now is iterating through all the rows in the datasource as below

var grid = $("#MyKendoGrid").data("kendoGrid");

var data = grid.dataSource.data();

$.each(data, function (i, row) {

//do something

});

But what if I want to iterate on the rows of a particular page.
I can get the current page by grid.dataSource.page(); Then what's next?

Please advise.

Post Grid Data back with Form

Hi,

I have a "Create" form in my MVC application that has some fields like firstName, lastName... and a Kendo grid. The grid has two columns (namve/value pairs).

I can't create the values in the grid until I create the rest of the form. I need to post all of the data on the form back at the same time.

Is there a way to post the grid data along with the rest of the form data?

How to fail an Upload save handler?

Hello,
I'm uploading a CSV file and try to parse it.
I want to return to the client a responsive message what is the issue (as I found it).

I've tried this:

Response.StatusCode = (int)System.Net.HttpStatusCode.BadRequest;

Response.ContentEncoding = Encoding.UTF8;
            Response.ContentType = "application/json; charset=utf-8";

return Json(myResponse, Response.ContentType, Response.ContentEncoding);

Where myResponse is of a specific type containing my status code. I'm checking the value of my Status Code (called Rc) and act accordingly.

I'm changing the StatusCode, because the retry button appears and the user can try uploading again easily).
It work fine in Chrome and FF, but not in IE (all in my dev server)
I've change the behavior to be like this:

// for IE responseText
if (Request.Browser.IsBrowser("IE"))
{
     Response.StatusCode = (int)System.Net.HttpStatusCode.OK;
     Response.ContentType = "text/html; charset=utf-8";
}
// End of

and that solve the issue for IE.

BUT:
When moved to testing environment, the myResponse is holding the 'BadRequest' string and not my Json response, and then I don't have any info to display to the client.

So - I've removed the line

Response.StatusCode = (int)System.Net.HttpStatusCode.BadRequest;

and my js handler look like that
function onUploadSuccess(e) {
            //alert("Success (" + e.operation + ") :: " + getFileInfo(e));
 
            if (e.response.Rc != 'OK')
                addFileRow(e.files[0].name, e.response.ErrorMessages, e.response.CurrentTime, "uploadRowError", "");
            else {
                var runCmd = "<div .... />";
                addFileRow(e.files[0].name, e.response.ErrorMessages, e.response.CurrentTime, "uploadRowSuccess", runCmd);
            }
        }
And the question:
Can I mark the operation as failed in the onSuccess handler ?
Thanks

Kendo UI Batch Editing Error in MvcConrib Portable area project

Hi,
I am using KendoUI Grid in ASP.NET MVC3 Application and using MvcContrib.Mvc3-ci.3.0.73.0 for portable view. Everything in the grid working perfect. But having problem when I add "Batch Editing" feature. My error screen showing message like this:

The best overloaded method match for 'Kendo.Mvc.UI.Fluent.GridEditingSettingsBuilder<KendoGridMvcCodeFirst.Models.Customer>.Mode(Kendo.Mvc.UI.GridEditMode)' has some invalid arguments

I guess the issue is related to MvcContrib, because same code works in my another test application. My view page code look like this:

@(Html.Kendo().Grid<KendoGridMvcCodeFirst.Models.Customer>()
.Name("Customers")
.ToolBar(tb => tb.Create())
.Editable(editable => editable.Mode(GridEditMode.InCell))
.Pageable()

.DataSource(dataSource => dataSource.Ajax()
.Batch(true)
.Model(model => model.Id(c => c.CustomerID))
.Read("GetCustomers", "Home")
.Update("UpdateCustomer", "Home")
.Create("InsertCustomer", "Home")
.Destroy("DeleteCustomer", "Home"))
.Columns(cols =>
{
cols.Bound(c => c.CustomerID).EditorTemplateName("Integer");
cols.Bound(c => c.Name).Width(300);
cols.Bound(c => c.Phone);
cols.Bound(c => c.Email);
cols.Command(cmd =>
{
cmd.Edit();
cmd.Destroy();
});
})
)

Please help.

Thanks,
ARIF
