I have a DropDownList I'm creating inside a KendoGrid - it binds fine, but it's inside of an IFrame. Under a specific set of circumstances (two rows of data), the popup direction is Down and the selection list is hiding "behind" or "inside" the IFrame. I need the PopUp list to either go Up or be brought forward over the IFrame.... thoughts?? I've tried this a few ways using z-index and setting the popup to append to the Form or IFrame better, but no luck... 

Is there a way to set the default pageSize on the dataSource for a grid when initializing from HTML? I'm using mostly the JavaScript widgets (hence posting in the web forum), but I also have licensed access to the JSP wrappers. I just have not gotten any experience or knowledge using the kendo taglib yet.

Goal: Increase performance.

Background: due to some legacy code, I have to initialize the grid from an HTML table. Most of the time it works just fine, but sometimes this page will have a large amount of data (thousand of rows), and so the grid is very slow, or locks up.

Documentation has suggested using virtual scrolling, and while setting the virtual scroll option on the widget "works" when initializing from HTML, it's still very slow. I see no noticeable difference in performance. My thought is that this could be because I'm not setting a pageSize on the dataSource. It would need to be done (I think) before initializing the grid, otherwise the page will still be very slow to load and could still lock up; I don't see how I can do that.

Is there a way to do this with the JSP wrappers/taglib? Or is there something I'm missing in the JavaScript side of things?

I have downloaded and extracted the Kendo UI examples to my local PC.  I setup an IIS application and mapped it to the web examples folder.  However, when I attempt to run the web examples such as SPA Sushi, the following page content is displayed:

Note:
Security restrictions prevent this example from working in all browsers when the page is loaded from the file system (via file:// protocol). If the demo is not working as expected, please host the Kendo folder on a web server.

I am running the app through IIS (e.g. http://localhost/KendoUI/web/spa/Sushi.html) on a PC using 64 bit Windows 7.

Any ideas on how to resolve this?

thanks

Is it possible to use Markdown within the Kendo editor? I have spent a few days trying to find this and cannot. I was under the impression that the parsing engine could be substituted.

Hi,

I have the grid and the model below. Everything works but getSum, I get a "getSum is not defined" error. Any idea?

    <div class="k-widget" 
      data-role="grid"
      data-bind="source: nbh"
      data-columns="[{title: 'Tâche', field: 'task'}, {title: 'Heures', field: 'hours', width: '125px', format: '{0} h', aggregates: ['sum'], 
        footerTemplate: 'Total: #= data.hours? data.hours.sum: 0 # h'}, {title: 'Personnelle', field: 'personal', hidden: true, 
        groupHeaderTemplate: '#= value? \'Projets\':\'Tâches personnelles\'# (#= getSum(value) # h)'}]">
    </div>

bound to this model:

        var model = kendo.observable({

            nbh: new kendo.data.DataSource({
                aggregate: [{ field: "hours", aggregate: "sum" }]
            }),

            getSum: function (value) {
                var datasource = this.nbh;
                var result;
                //loops through the dataSource view
                $(datasource.view()).each(function (index, element) {
                    //compares view value with the current template value
                    if (element.value === value) {
                        result = element.aggregates.hours.sum; //gets the aggregate value
                    }
                });

                return result;
            }

        });

I am creating folders in tree structure like we have windows explorer.My requirement is that if I am dropping a node into another node and the target node already contains a node with the same name as of source node then the source node should be placed back to its original position.The checking of same node name takes place in the controller and it returns false if it's duplicate.At this moment, I want to move the node at it's original position.I have tried e.setValid(false) and e.preventDefault() but it's not working. Please provide me the solution.

Hi,
I have this grid example:
http://plnkr.co/edit/Oh5wApcRePJqNv0F31HJ?p=preview
In it, I state that one field will be to type: "date".
In the array creation, every corresponding element is equal to "new Date()".
Nevertheless, in the grid itself, the value appears as a string.
Any idea why?

Hi,
   I have a problem getting the Hierarchical Data Source to work with a CORS configured WebAPI server whereas a standard Data Source works fine for a grid.  My sample code for a working grid on a CORS data source is as follows:

var buildTestGrid = function () {
        // Setup Data Source
        var ds = new kendo.data.DataSource({
            transport: {
                read: function (options) {
                    console.log("Setting-up testGrid");
                    console.log("Token: " + token);
                    $.ajax({
                        cache: false,
                        url: getUrl("api/v1/items(parent_id=null,is_template=false)"),
                        type: "GET",
                        headers: { "X-Token": token },
                        success: function (response) {
                            console.log("Test Grid... it's ALIVE!");
                            if (response == null || response == "null")
                                console.log("ERROR: No response");
                            else {
                                options.success(response);
                            }
                        },
                        error: function (xhr, status, error) {
                            console.log("Test Grid Error");
                        },
                    });
                },
                batch: true
            },
            pageSize: 10
        });


        // Now configure the grid
        $("#testGrid").kendoGrid({
            dataSource: ds,
            groupable: false,
            sortable: true,
            pageable: {
                refresh: true,
                pageSizes: true,
                buttonCount: 5
            }
        });
    }

However, the data source fails when building a tree control using the following code:

    var buildTestTree = function () {
        // Setup the data source
        var ds = new kendo.data.HierarchicalDataSource({
            transport: {
                read: function (options) {
                    console.log("Setting-up testGrid");
                    console.log("Token: " + token);
                    $.ajax({
                        cache: false,
                        url: getUrl("api/v1/items(parent_id=null,is_template=false)"),
                        dataType: "json", // "jsonp" is required for cross-domain requests; use "json" for same-domain requests
                        type: "GET",
                        headers: { "X-Token": token },
                        success: function (result) {
                            console.log("Test Tree... it's ALIVE!");
                            if (result.length == 0) {
                                console("ERROR: No response");
                            }
                            options.success(result);
                        },
                        error: function (result) {
                            console.log("Test Tree Error");
                            options.error(result);
                        }
                    });
                },
            }
        });


        $("#testTree").kendoTreeView({
            animation: {
                collapse: {
                    duration: 400,
                    effects: "fadeOut"
                },
                expand: {
                    duration: 400,
                    effects: "fadeIn"
                }
            },
            dataSource: ds,
        }).data("kendoTreeView");
    }

Strangely if I configure my service to just return an error message the GET request works fine, but when the tree actually get's data it appears to make a second call and gives the following error:

OPTIONS <URL> 405 (Method Not Allowed) jquery-1.9.1.js:9597
OPTIONS <URL> Invalid HTTP status code 405 jquery-1.9.1.js:9597
XMLHttpRequest cannot load <URL>. Invalid HTTP status code 405
