Hello,

I would like to catch the grid request i.e. when sorting or grouping via server and execute on some modal dialog when OK clicked. As I understand on requestStart we can perform some actions, but further execution flow will proceed. In my case I would like to display login dialog + some other login selections and if login succeeds, continue with the request. Is it possible?

Thanks

Hi,

How do I add a default filter on a kendo.grid ?

I have a filter on a boolean, which is working just fine, but I would like TRUE to be the selection by default.

I am quite sure that I have done this before and then removed it again, and now I can't remember howto :-(

I'am aware, that server side operations require more than just setting the default filter selection, but once I have figured out how to set the filter in the view, then I figure out the rest.

So, how to set default filter in the view ??

Thank you in advance.

It is probably easy as you might say it is. But the fact remains is that I can not find the solution anywhere.

 Here is my code:

public ActionResult Edit([DataSourceRequest] DataSourceRequest gridRequest, Sub editSub)
        {
            if (ModelState.IsValid) 
            {
                Sub subToUpdate = db.Subs.FirstOrDefault();
                subToUpdate.SFirst = editSub.SFirst;
                subToUpdate.SLast = editSub.SLast;
                subToUpdate.SEmail = editSub.SEmail;
                db.SaveChanges();
            }

            return Json(new[] { editSub }.ToDataSourceResult(gridRequest, ModelState));
        }

Every time I modify a different row the first row gets overwritten. I assume that I nee to specify the ID in here: db.Subs.FirstOrDefault(); 

I cannot find how to?

I am trying to do an application in which I have three related listviews. The second listview is charged in dependency of the item selected in the first one, and the third depends on the second one. When I select an item I need to pass the controller, the id of this item not its text. It works perfectly in the first listview but reaches an error in the second one.

I copy here my view:

@model PruebaTelerik.Models.CompanyGroupModel

<script type="text/x-kendo-tmpl" id="ListViewTemplate">
<option value="#:Id#">#:Description#</option>
</script>

<script>
function onChange(args) {
var dbConnObj = $("#ListAgrupaciones").data("kendoListView");
var index = dbConnObj.select().index();
var dataItem = dbConnObj.dataSource.view()[index];
var _id = dataItem.Id;
cargarDatos('Companies/LoadCompanies', "#ListCompanies", _id);
}

function cargarDatos(urlEspecifica, listaModificar, _id) {
$.ajax({
url: urlEspecifica,
type: 'POST',
contentType: 'application/json',
dataType: 'json',
data: JSON.stringify({ nombre: _id }),
success: function (nombre) {
$(listaModificar).kendoListView({
dataSource: nombre,
template: kendo.template($("#ListViewTemplate").html())
});

},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Error: " + XMLHttpRequest.responseText);
}

});

}

function onChangeCompanies(arg) {
debugger;
var objeto = $("#ListCompanies").data("kendoListView");
debugger;
var indice = objeto.select().index();
debugger;
var item = objeto.dataSource.view()[indice];
debugger;
var _id = item.Id;
debugger;
alert(_id);
cargarDatos('Companies/LoadProducts', "#ListProducts", _id);
}

</script>

The controller has this methods:

[HttpPost]
public ActionResult LoadCompanies(string nombre)
{
int ID = -1;
int dummy;
if (Int32.TryParse(nombre, out dummy))
{
ID = dummy;
}
if (ID == 1)
{
nombre = "agrupación1";
}
if (ID == 2)
{
nombre = "agrupación2";
}
SelectListModel selectList;
List<SelectListModel> listAgrupaciones = new List<SelectListModel>();
selectList = new SelectListModel() { Id = 3, Description = nombre + " 1" };
listAgrupaciones.Add(selectList);
selectList = new SelectListModel() { Id = 4, Description = nombre + " 2" };
listAgrupaciones.Add(selectList);
return Json(listAgrupaciones, JsonRequestBehavior.AllowGet);

}

[HttpPost]
public ActionResult LoadProducts(string nombre)
{
int ID = -1;
int dummy;
if (Int32.TryParse(nombre, out dummy))
{
ID = dummy;
}
if (ID == 1)
{
nombre = "compañía1";
}
if (ID == 2)
{
nombre = "compañía2";
}
SelectListModel selectList;
List<SelectListModel> listAgrupaciones = new List<SelectListModel>();
selectList = new SelectListModel() { Id = 1, Description = nombre + " 1" };
listAgrupaciones.Add(selectList);
selectList = new SelectListModel() { Id = 2, Description = nombre + " 2" };
listAgrupaciones.Add(selectList);
return Json(listAgrupaciones, JsonRequestBehavior.AllowGet);
}

Could anyone help me? Thanks a lot.

Trying to group together data returned from my controller into a chart where items are categorized and grouped by type. Similar to the spain electricty production chart (binding to remote data) or the stock prices (binding to grouped data).

Here's the JSON I've got coming out of the controller

Each type of request (RegionRequest, AuthorizationRequest, etc.) would be the group. Inside that group the data array contains a series of clients and the count of those requests.

After an hour of mucking about with the wrapper I'm still lost on how to group this data and what goes where. I'm not using a C# model so things like the SeriesDefaults doens't work for me because I can't use a lamdba expression to set it up. I'm in control of all the parts here (markup or JSON) so I can output the JSON in a flatter format or something (although I really don't want to output the complete list of request types as these counts are low but outputting 300+ elements doesn't make sense when I can count it in LINQ on the server side much faster).

So any advice on how the data should be formatted or what the wrapper should look like given this data? Do I have to create a view model to do this (which is fine, I just didn't want to do it for a single chart).

BTW I really struggle with the documentation and examples on the site. They're great but only when they perfectly fit in your scenario. In my case for example I can't find an example where a) it's using the MVC wrapper b) it's binding to remote data c) the data is grouped d) there's no C# model. The descriptions of some of the MVC wrappers is just horrible. For example the description for the CategoryAxis says "Configures the category axis" and the example code in the documentation has an example pulling a single property from a model. Can you configure multiple categories? What if you don't have a model?

I really hope I'm not the only one feeling this. The wrappers are great but I'm constantly having to find snippets and samples on StackOverflow to try to figure out what's going on and how to do things, and usually it results in finding something "close" to what I want that I can tweak and sometimes this means finding a jsfiddle that someone has put together and reverse engineering the html/js to what should be plugged into the MVC wrapper. Yes I know you don't have to use the wrappers but they're there for a purpose and I'd rather try to use them instead of raw markup.

Thanks

I am trying to color a row based on the results that returned from the datasource.

Is there a good clean way to accomplish this? The result comes back as a Hex value (not shown in the code below) so it can be a simple concatenation if needed in my MVC or Jquery. I just dont know the best way to perform this. Please help. Thanks
