Changing the ContentType in the http request

Hello,

I am looking for a way to change the contenttype in the http request, it seems you can do it in jquery but there doesn't seem to be a way to do it with the razor html helpers. I would think it would work something like line #6. Is this possible?

Thanks,

01..DataSource(dataSource => dataSource

02. .Ajax()

03. .PageSize(20)

04. .ServerOperation(true)

05. .Events(events => events.Error("error_handler"))y

06. .Create(update => update.Action("Customer_Create", "Customer", ContentType="Application/Json")

07.

08. )

09. .Read(read => read.Action("Customer_Read", "Customer"))

10. .Update(update => update.Action("Customer_Update", "Customer"))

11. .Destroy(update => update.Action("Customer_Delete", "Customer"))

12. .

BindTo After Read Action

Hello.
I have a scheduler and an EditorTemplate.
I want to bind a multiselectfor after the reading method. (with my Model which is populated in the read Method).
I suppose the .BindTo() Display nothing because the read method 'll be call after this one.

So here is my scheduler :

@(Html.Kendo().Scheduler<iMail.Web.Models.TaskViewModel>()

.Name("scheduler")

.Date(DateTime.Now)

.Timezone("Etc/UTC")

.Views(views =>

{

views.DayView();

views.WeekView();

views.MonthView();

views.AgendaView(agenda => agenda.Selected(true));

})

.Selectable(true)

.Timezone("Etc/UTC")

.Events(e =>

{

e.Edit("onEdit");

e.Change("onChange");

})

.Editable(editable =>

{

editable.TemplateName("_EditorTemplatePartial");

})

.DataSource(d => d

.Model(m =>

{

m.Id(f => f.TaskID);

m.Field(f => f.Title).DefaultValue("No title");

m.RecurrenceId(f => f.RecurrenceID);

m.Field(f => f.Priority);

m.Field(f => f.TypeID);

})

.Events(e => e.Error("error_handler"))

.Read (read => read.Action("TasksRead", "Calendar").Data("additionalInfo").Type(HttpVerbs.Get))

.Create(create => create.Action("TasksCreate", "Calendar").Data("additionalInfo"))

.Destroy(destroy => destroy.Action("TasksDestroy", "Calendar").Data("additionalInfo"))

.Update(update => update.Action("TasksUpdate", "Calendar").Data("additionalInfo"))

)

And here is my MultiSelectFor in the _EditorTemplatePartial.cs file.

<div id="AttendeeAlreadyInvited">

<div data-container-for="AlreadyInvitedID" class="k-edit-field">

@(Html.Kendo().MultiSelectFor(model => model.AlreadyInvitedID)

.HtmlAttributes(new { data_bind = "value:AlreadyInvitedID" })

.DataTextField("Name")

.DataValueField("ID")

.BindTo(Model.Invited)

)

</div>

Model.Invited has a structure like this :

public class CalEmployeeLight

{

public int ID;

public string Name;
}

Here is a part of my model :

public class TaskViewModel : Kendo.Mvc.UI.ISchedulerEvent

{

   public int TaskID { get; set; } //each event have an ID.

   .....

   public IEnumerable<

int> AlreadyInvitedID { get; set; }

public ICollection<CalEmployeeLight

> Invited { get; set; }

}

Each event in the Scheduler have an ID (TaskID)

The Model is populated in the TaskRead fct and works correctly.
But my multiselectFor is empty.

How can i use .bindTo() fct in the MultiSelectFor() after the Model is populated by "TaskRead" ?

Kendo Ui - Dependency Injection

Hi,

I'm currently developing an application with the support of Windsor Castle (DI container).

As I also want to use Kendo in this project, I started with a simple Grid.

Suddenly the Exception "no parameterless constructor defined for this object" came up.

I've found some threads about this on the net - like this one (http://www.telerik.com/forums/binding-to-an-arraylist-4539b158237a) - which are talking about the same error.
But the solution suggested in those are not satisfying, because I don't want to introduce a parameterless constructor if I don't need one (beside of Kendo).

Is there a way to use Kendo without having parameterless constructors?

Thanks in advance.

Kind regards
Daniel

Kendo MVC Grid Ajax custom binding to dynamic resultset

Hi,

I have a stored procedure which returns 2 result sets. First result-set is collection of Columns ,data types, column order, Is column sortable and is column filterable.
Second resultset is actual data for the columns which are there in first resultset. So in short my stored procedure returns the metadata for the columns and their values. I dont know in advance what will be my columns list. At code level stored procedure is returning a dataset with 2 tables inside it. Now I want to bind the kendo grid with the second table of dataset and first table of dataset will give me information about the columns which are suppose to have sort ,filter criteria. My problem is i dont know the columns in advance still i execute the stored procedure then how can i use DataSourecRequest object to find out custom sorting and filtering stuff.
e.g.
private CriteriaDto GetCriteriaDtoValues(DataSourceRequest request)
{
var criteriaDto = new DocumentHistoryCriteriaDto { Filters = new Dictionary<string, string>() };
if (request.PageSize == 0)
{
request.PageSize = 20;
criteriaDto.PageSize = 20;
}
else
{
criteriaDto.PageSize = request.PageSize;
}
if (request.Sorts != null && request.Sorts.Count > 0)
{
foreach (SortDescriptor sortDescriptor in request.Sorts)
{
if (sortDescriptor.SortDirection == ListSortDirection.Ascending)
{
switch (sortDescriptor.Member)
{
case "ActivityDate": //This is hard coded column just for example but by this time i dont knwo what are the columns there in resultset
criteriaDto.SortBy = "ActivityDate";
criteriaDto.IsSortAcending = true;
currentSortType = criteriaDto.SortBy;
break;
case "RecordId": ////This is hard coded column just for example but by this time i dont knwo what are the columns there in resultset
criteriaDto.SortBy = "RecordId";
criteriaDto.IsSortAcending = true;
currentSortType = criteriaDto.SortBy;
break;
}
}
else
{
switch (sortDescriptor.Member)
{
case "ActivityDate": //This is hard coded column just for example but by this time i dont knwo what are the columns there in resultset
criteriaDto.SortBy = "ActivityDate";
criteriaDto.IsSortAcending = false;
currentSortType = criteriaDto.SortBy;
break;
case "RecordId": //This is hard coded column just for example but by this time i dont knwo what are the columns there in resultset
criteriaDto.SortBy = "RecordId";
criteriaDto.IsSortAcending = false;
currentSortType = criteriaDto.SortBy;
break;
}

}
}
}
else
{
criteriaDto.SortBy = "ActivityDate"; //This is hard coded column just for example but by this time i dont know what are the columns there in resultset
criteriaDto.IsSortAcending = true;
currentSortType = criteriaDto.SortBy;
}
if (request.Filters != null && request.Filters.Count > 0)
{
foreach (FilterDescriptor filterDescriptor in request.Filters)
{
switch (filterDescriptor.Member)
{
case "RecordId": //This is hard coded column just for example but by this time i dont know what are the columns there in resultset
criteriaDto.Filters.Add("LoanNo", filterDescriptor.Value.ToString());
break;
}

}
}
if (request.Page > 0)
{
criteriaDto.PageNumber = request.Page;
}
return criteriaDto;

}

Also I have written below ajax method which is calling the above code before it calls the Store procedure. Can you provide some exmaple on how I can actually
pass the data set's data table collection to view in MVC and How can i bind it to grid for 2nd table in dataset and how can i make use of first table
to decide which columns to sort and filter using DataSourceRequest object

public ActionResult View_ByRecordId_Read([DataSourceRequest] DataSourceRequest request)
{

DataSet dsModel;
int total=0;
int RecordId = 2;
string RecordValue = "0000224374";
int timeFrame = 50;

criteriaDto = this.GetCriteriaDtoValues(request); //So here it calls this method to decide which columns got sort and filer criteria but actually by this time i dint get my procedure called so how can i figure it out which columns are meant to be for sorting and filtering.

dsModel = this._Service.GetDocumentView (userDto.Id,RecordId,RecordValue,timeFrame,criteriaDto,Guid.NewGuid()); //This is calling stored procedure and returning a dataset with 2 tables inside it.

if (dsModel != null && dsModel.Tables.Count > 0) {
bool tryParse=int.TryParse(dsModel.Tables[1].Rows[0]["TotalCount"].ToString(),out total); }

var result = new DataSourceResult() { Data = dsModel.Tables, Total = total };

return Json(result);

}

Update model values on click of task

So I'm pretty new to using this component, so I'm not very familiar with it yet.

Here's what I'm trying to do:

I have a scheduler that I'm pre-populating with a lot of tasks. I don't want the user to be able to add, delete, or update anything. However, on selecting or clicking (or double clicking, whatever works best) I want to be able to update some other value in the model that was passed into the view.

For example: When user clicks on a task at 12:00 PM I don't want to show any pop ups or anything, but I want to set Model.appontmentTime equal to the tasks start time (i.e. 12:00 PM).

Also, as a side issue, for some reason when I attach a task to an owner as listed in the resources, the task is not showing in the right color. Am I doing something wrong there?

So Far I have:

01.@(Html.Kendo().Scheduler<Humana.RetailSales.CGX.Site.TaskViewModel>()

02. .Name("timeSlots")

03. .Views(views => { views.WeekView(); })

04. .Height(300)

05. .Date(Model.appointmentCalendarRenderStartDate)

06. .Height(400)

07. .AllDaySlot(false)

08. .MajorTick((int)Model.timeSlotInterval.TotalMinutes)

09. .MinorTickCount(1)

10. .Min(Model.appointmentCalendarRenderStartDate)

11. .Max(Model.appointmentCalendarRenderFinishDate)

12. .Resources(resource =>
