[Solved] POST to ASP.NET Web API parameter binding problem

I have a Kendo Scheduler posting to a C# Web API when a new schedule event is created. The problem is with parameter binding - the web API method does not receive the posted data properly.

When I look at the server request in Fiddler, the content type is json, but the request body is URL encoded. How to get the Scheduler to encode the event as JSON?

POST http://localhost:58623/api/booking HTTP/1.1
Host: localhost:58623
Accept: application/json, text/javascript, */*; q=0.01
Accept-Language: en-gb,en;q=0.5
Accept-Encoding: gzip, deflate
Content-Type: application/json; charset=utf-8
Referer: http://localhost:58623/Booking
Content-Length: 2141

models=%5B%7B%22Id%22%3A0%2C%22Title%22%3A%22No+title%22%2C%22Start%22%3A%222013-06-11T08%3A00%3A00.000Z etc...

Here is my js file:

        $("#scheduler").kendoScheduler({
            date: new Date("2013-06-13"),
            startTime: new Date("2013-06-13T07:00"),

Custom Ajax Bound grid: switch to client side paging on the fly

I have a custom bound ajax grid with server operation (for paging, sorting, filtering etc). On the server side it would sometimes be more efficient to fetch all the data rather than just one page. If I return more than a page worth of data the grid just shows it all (as you would expect!), so what I want to do is switch to client side paging if more than a page worth of data is returned... is this possible?

I've tried setting the option on the grid during the DataSource.RequestEnd event, but this doesn't seem to have any real effect (I've tried also calling grid.Refresh, grid.SetDataSource).

[Solved] Multi Select Issue in Grid

Dear Telerik，

I use grid in my project and would like to provide multi-select options in user-editing. But I got some strange issue using multi-select.
In my project I use multi-select like this.

$("#grid").kendoGrid({

dataSource: dataSource,

pageable: true,

resizable: true,

sortable: true,

filterable: true,

toolbar: ["create"],

save: function (e) {

e.model.dirty = true;

},

detailTemplate: kendo.template($("#template").html()),

detailInit: detailInit,

columns: [

//{ field: "id", title: "id Name" },

{ field: "Server_Name", title: "Server Name", width: "150px" },

{ field: "Server_IP_Address", title: "Server IP Address", width: "120px" },

{ field: "Data_Center_City", title: "City", width: "56px" },

{ field: "Data_Center_Location", title: "Data Center Location", width: "156px" },

{ field: "Server_Type", title: "Server Type", width: "100px" },

{ field: "Server_Instance", title: "Server Instance", width: "120px" },

{ field: "Environment", title: "Environment", width: "100px", editor: appDropDownEditor },

{ command: ["edit", "destroy"], title: " ", width: "170px" }],

editable: "inline"

});

}

function appDropDownEditor(container, options) {

$('<input required data-bind="value:' + options.field + '"/>')

.appendTo(container)

.kendoMultiSelect({

dataTextField: "text",

dataValueField: "text",

dataSource: [ { text: "PRD" }, { text: "QA" }, { text: "DEV" } ]

});

}

I wonder where I got wrong and it appeared with a strange <input> and a <span> unexpected. Just like the image.

I'd like to ask you that how can I use multi-select to get user input in dropdown list? I checked the demos but only found demo for <select> tag or for MVC usage.
I'm looking forward for your reply.

Migration from ASP.NET Scheduler

I have some concerns on the viability of migrating from ASP.NET Scheduler to Kendo UI scheduler. Particularly, the manner in which recurrence is handled in the two products is handled. It would be VERY GOOD if both systems store data in the same way. At the very least, have a way to convert data over from one system to the other.

Otherwise, migration would be very hard to do.

Thanks,

Brian

Kendo Grid Remote Virtual Data With Paging Support

It doesn't seem to work for me
It is supposed to but I haven't found complete documentation on how to do this. For example I was able to set Virtual to true with the following code(note I am using MVC extensions).

.Scrollable(s => s.Virtual(true).Height(532))

The server code

public ActionResult IndexEmployeesGridData([DataSourceRequest] DataSourceRequest request)

{

var model = _employeeService.GetEmployeesDataViewModel(request.Page, request.PageSize).Where(e => e.IsActive);

return Json(model.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);

}

Code works for the first page only.
The grid fills up with the first page of data but nothing else. Since the grid has no idea how many rows are in the database it just forgets about any more records. I don't know how to complete the last part to get the dynamic virtual paging to work properly. Any help would be greatly appreciated.

Thanks

This of course doesn't work well for large datasets because you have to have some sort of paging set up on the server. There is documentation saying that you should add the parameters page, pageSize, take, and skip etc.. in order for this to work. I did this but then I get an error.

The server code

public ActionResult IndexEmployeesGridData([DataSourceRequest] DataSourceRequest request, Int32 page, Int32 pageSize)

{

var model = _employeeService.GetEmployeesDataViewModel(page, pageSize).Where(e => e.IsActive);

return Json(model.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);

}

The erorr message
Server Error in '/' Application.The parameters dictionary contains a null entry for parameter 'page' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult IndexEmployeesGridData(Kendo.Mvc.UI.DataSourceRequest, Int32, Int32)' in 'SafetyPlus.Controllers.EmployeeController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters

Using the Data property I was able to get data to the server.

.DataSource(datasource => datasource

.Ajax()

.PageSize(20)

.Read(read => read.Action("IndexEmployeesGridData", "Employee").Data("sendStatus"))))

And the script that gets the parameters to take.

<script type="text/javascript">

function sendStatus(options)

return {

page: options.page,

pageSize: options.pageSize

};

}

</script>

Help needed.

Slow ServerPaging

Hi,

I was trying to create a quick KendoUI demo with a small table.

The table is about 14 columns with 139 row.

The demo consists of a chart to display the first row of the grid and 2 grids just to test that it is possible to show 2 grids...

I used firebug to test the load time... it takes 1.39 secs on average... would like it to be fast if possible...

But what is annoying is that when I click to another page on the grid, each page showing only 10 records, it takes over 2 seconds?!?

I don't understand why it takes longer to page across pages than to load the entire page...

I also tried this via AJAX using MVC but the same page takes 6 seconds to load and paging there takes 6 seconds too...

Can anyone tell me why the demo I am using with BindTo is taking so long to page between pages?

I've been looking at JQgrid and its instantaneous there.... I can't see why it is so slow in KendoUI....

Regards,

William

[Solved] How to post data using parameterMap in kendo scheduler

Hi,

I just want to know how to post data using the parameterMap function in kendo scheduler, as what I understand the default type is "Get", for some reason I need to do a "Post" type, It seems that my code (see sample code below) does not work, and when I look into the posted data the result is always something like this ( f=%22somedata%22 ) Is there something wrong in my code?

dataSource: {

transport: {

read: {

type: "POST",

url: "myurl",

dataType: "json",

contentType: "application/json; charset=utf-8"

},

parameterMap: function (options, operation) {

return { f: JSON.stringify("somedata") };

}

},

schema:

{

//some code here....

}

I also try the code below as what I see in this link http://jsfiddle.net/Xhrrj/4/.. but it seems not working to me.. the result of the posted data is something like this ( f= somedata )...

parameterMap: function (options, operation) {

$.extend({}, options, { f: "somedata" })

}

Thanks,

Regards,
Jesson
