Hi,
I am following the example 
var crudServiceBaseUrl = "http://demos.kendoui.com/service",
dataSource = new kendo.data.DataSource({
transport: {
read: {
url: crudServiceBaseUrl + "/Products",
dataType: "jsonp"
},
update: {
url: crudServiceBaseUrl + "/Products/Update",
dataType: "jsonp"
},

However, when I am using my Web API address for update, it shows "Request Method:GET Status Code:405 Method Not Allowed". My Web api Update method is a HttpPost method. Any suggestions please??

I am relatively new to MVC and web programming in general but have used almost all the other Telerik controls (Forms, WPF, Silverlight). I downloaded and installed what I believe to be the Q2 2013 Kendo MVC controls. All of the documentation and examples use Html.Kendo()... But all I can find are Html.Telerik()... This would not be a problem except the documentation and demos do NOT match the api I appear to have. For example I am working with the Grid control and there is no OnChange event like in the demos and documentation but there are OnRowSelect and OnRowSelected events which are not documented.

Am I missing something?

Thanks

Hello Team, 

There is filter menu which get displayed when you click filter icon. Have added the code to display the same when you hit enter or space bar key . Below is the piece of code


Now once i am done i want to move the focus the tab on the clear filter icon and move to the next element . I am not able to do this. even i tried to set the focus. 

Is it possible to do ?

  $('.t-icon.t-filter').each(function () {
        $(this).attr('tabindex', '0')
        $(this).attr('title', 'Edit Filter')

        $(this).live('keydown', function (e) {
            var keyCode = e.keyCode || e.which;
            if (keyCode == 13 | keyCode == 32) {
                $(this).click();                     // show the filter pop up on enter or spacebar

                
            }

        });
    });

Hi

I'm trialling at the moment but i'm having a problem with the grid control.

I get the intial grid up with data to begin with but when i try to page or sort etc internet explorers asks whether I want to download the response and Firefox just displays the raw json data in a page.


I was wondering if anyone knew where I was going wrong with this one?
Here's the code:

private

IEnumerable<ReqAssess> GetRequests()

 {

 

var reqassess = reqAssessService.GetReqAssess();

return reqassess;

}

public

ActionResult Products_Read([DataSourceRequest] DataSourceRequest request)

 

{

 

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

}

@(Html.Kendo().Grid(Model)

.Name(

 

"Grid")

.Columns(columns =>

{

columns.Bound(p => p.ReqId).Width(100).Groupable(

 

false).Title("Request ID").ClientTemplate(

"# if (Urgent == \"Y\") { #" +

 "<div style=\"background-color: Red;\">#: ReqId #</div>" +

 "# } else { #" +

 "#: ReqId #" +

 "# } #"

 );

 columns.Bound(p => p.CompId).Title(

 

"Company ID").Width(110);

 columns.Bound(p => p.Facid).Title("Facility ID").Width(110);

 columns.Bound(p => p.Mtrlcode).Title("Code").Width(90);

 columns.Bound(p => p.Tradename).Title("Tradename").Width(170);

 columns.Bound(p => p.Requested).Format("{0:dd/MM/yyyy:hh:mm:ss}").Width(110); ;

 columns.Bound(p => p.DateDue).Format("{0:dd/MM/yyyy}").Title("Date due").Width(100); ;

 columns.Bound(p => p.Completed).Format("{0:dd/MM/yyyy}").Title("Completed").Width(100); ;

 columns.Bound(p => p.Status).Width(150);

 columns.Bound(p => p.AssignedTo).Width(100);

 

})

 .ClientDetailTemplateId(

 

"employeesTemplate")

 .Groupable()

 .Pageable()

 .Sortable()

 .Scrollable()

 .Filterable()

 .Selectable()

 .Pageable(pager => pager

 .Refresh(

 

true)

 .PageSizes(new int[4] {10, 20, 30, 40}))

 .ColumnMenu()

.Resizable(resize => resize.Columns(true))

 .Reorderable(reorder => reorder.Columns(true))

 .DataSource(dataSource => dataSource

 .Ajax()

 .Read(read => read.Action(

 .PageSize(30)

 ))

I'm biding a treeview to a remote data and at this point the data is displayed correctly. The problem: when I change the data in the database and refresh my page, the treeview doesn't reflect the new data. It seems that the treeview is not calling the json action anymore after the first load.

I tried to work with LoadOnDemand and several other methods, but nothing worked so far. I need to refresh the data because when users drag and drop the nodes, the treeview will be updated in the database.

** Code is attached. I also just noticed that it works on Chrome but not IE 10. Thank you for any help.

I'm following this demo code: http://demos.kendoui.com/web/treeview/remote-data.html

This is my json action:

public JsonResult Categories(int? id)
{

var categories = from e in db.Categories
where (id.HasValue ? e.ParentCategoryID == id : e.ParentCategoryID == 1)
orderby(e.OrderNumber)
select new
{
id = e.CategoryID,
Name = e.CategoryNames.FirstOrDefault().Name,
ParentId = e.ParentCategoryID,
hasChildren = db.Categories.Where(j => j.ParentCategoryID == e.CategoryID).Any()
}
;

return Json(categories, JsonRequestBehavior.AllowGet);
}

This is my treeview code:

Html.Kendo().TreeView()
.Name("treeviewcategories")
.DataTextField("Name")
.DataSource(dataSource => dataSource
.Read(read => read
.Action("Categories", "Settings")
)
)
.Events(events => events
.Select("onSelect")
.DragEnd("onDragEnd")
.Expand("onExpand")
)
.DragAndDrop(true) 

I have a grid that I can select a row on and then click a button on the grid to move that row's data item to a different grid.

This code has been working fine for months, but broke after the last official release.  I upgraded to the most up to date internal release today (2013.2.814), but still no luck.

Basically, anytime I run code like this:

I get a strange error in Firebug and no code after the select line executes.  The error looks a bit like this:
However, searching for the row by the selected class DOES work.  E.g.:

I don't think it should matter, but the grid as well as the script executing the code above are inside a partial view that's loaded into a Menu Widget.

Here's the code for the views:

Menu Widget Declaration:

Partial View (Grid + Script):

<script type="text/javascript">

    function ConfigureItemBook() {

   

        //Drives multi-selection of grid rows (Overrides native functionality)

        $("#ItemBook").delegate('tbody tr', 'click', function () {

            $(this).toggleClass('k-state-selected');

        });

 

        //Drive single selection by double click

        $("#ItemBook").delegate('tbody tr', 'dblclick', function () {

            $(this).addClass('k-state-selected');

            PopulateItem();

        });

    }

 

    function PopulateItem() {

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

 

        console.log("Manual Search");

        console.log($("#ItemBook tr.k-state-selected"));  //This works

        console.log("Manual Search + Get DataItem");

        console.log(grid.dataItem($("#ItemBook tr.k-state-selected")));  //This works

        console.log("Kendo Grid Select");

        console.log(grid.select());  //ERROR

        console.log("Kendo Grid Select + GetDataItem");

        console.log(grid.dataItem(grid.select()));  //ERROR

    }

</script>

 

@(Html.Kendo().Grid(Model)

    .Name("ItemBook")

    .TableHtmlAttributes(new { @style = "cursor:pointer;" })

    .Columns(columns =>

    {

        columns.Bound(i => i.DateCreated).Width(90);

        //Other columns omitted for brevity

    })

    .ToolBar(toolbar =>

    {

        toolbar.Custom().Text("Select").Url("#_").HtmlAttributes(new { onclick = "PopulateItem()" });

    })

    .Events(events =>

        events.DataBound("ConfigureItemBook");

    })

In out MVC app, we are using a Kendo grid to display/inline edit Department information. We also display a tree view of the Department hierarchy (see below). In Chrome when changes are made to the Department information the tree view dynamically changes, in IE10 this does not occur. We noticed through debugging that in IE10 the "GetDepartmentTree' action is only fired on initial load and is never called again, even when the department page is refreshed. In Chrome this action is fired with each change to the Department information. Any ideas on what we can do to make this more cross-browser compliant?

            @(Html.Kendo().TreeView()
                .Name ("DepartmentTree")               
                .HtmlAttributes(new {@class="dept-treeview"})
                .DataTextField("Name")
                .DataSource(ds => ds
                    .Read(read => read
                        .Action("GetDepartmetsTree", "Administration")
                        .Data("GetParameters")
                    )
                )               
                .LoadOnDemand(false)
            )

I have a ASP.NET WebAPI endpoint that is receiving the calls for upload and it appears to be working fine in that the file is uploaded and it returns appropriate JSON.  It is however secured using windows authentication which seems to be causing a problem with loading the thumbnails.  What seems to be happening is that the initial call to the upload endpoint returns a 401 which causes the client to resend the request with the authorization cookie.  It seems that in between those two calls the tiles get updated and an img for the thumb is created even though the thumb hasn't been created on the server yet.  This causes the thumb not to load and it won't even try to load again until the browser is refreshed.  

Without security everything seems to go fine unfortunately the windows auth is a requirement of this application.  Is there a way to force the initial request to
include the auth token or is there a way to delay the reloading of the tiles/images until the second call is complete?  Seems to be mostly working great other than this issue.

Thanks,

Is it possible to filter a column from a drop down list (from a foreign key look up table) - and if so what's the best way to do this?

The only way I can see to do this a present, is using a toolbar template - which isn't ideal but would be ok, but the example isn't for the MVC extensions ( http://demos.kendoui.com/web/grid/toolbar-template.html ), and it seems there should be an easier way in MVC.

Any examples would be helpful.

Thanks

I'm using the code above to load a colour picker, the Model.BackgroundColour and Model.TextColour are strings as below:

rgb(0,255,255)

but when the form loads, the initial colour is always black, can someone tell me what I'm doing wrong please, as looking at the documentation it seems this should work. I should also point out that passing a string as below:

#00FFFF

does work.

Thanks.
