I've tried to get this working using this aspnetmvc-ajax sample code from telerik found here.

https://demos.telerik.com/kendo-ui/grid/grouppaging

I'm using jquery ajax restful api for the remote data endpoint and I am returning the response in the exact format as shown in the above example but it doesn't work.

After the grid loads, an "undefined" is displayed as the first row in the grid despite the data from the ajax data call returning the data in the exact same format as shown in the above example.

I also added the code for the sample into my project and I tried a local data source in order to rule out jquery ajax as remote api being the problem with the same response data format as the sample code to see if the server side group paging is anyway dependent on the datasource.type being aspnetmvc.  In this case I also get the same error as seen in my jquery ajax grid with remote group paging.

Has anyone been able to get group paging for a grid using a custom function for the transport read (jquery ajax) configuration?

Can anyone confirm whether it should work for this use case? And does anyone have an example?

Thanks in advance and appreciate your help.

Best,

Don

This seems to be a pretty good example, but unfortunately it doesn't work:

http://docs.telerik.com/kendo-ui/controls/data-management/grid/how-to/Layout/apply-minimum-width-during-column-resize

Is this deprecated? The binding to the resizable-events doesn't seem to work.

Hello,

I have a problem using the drawing library for creating PDFs with blocks being styled with a column-count style sheet being set to something other than 1 - it seems as if the drawing library is erroneously taking into account the sum of of all columns height instead of the real height when placing the output in a PDF, and thus leaving lots of blank space on the pages.

A working example can be found at Kendo UI Snippet | Kendo UI Dojo (telerik.com) (based on the page templates example)

Is this a known problem, am I missing something or is there any way/workaround to fix this?

Thanks & kind regards,

Hermann

I've got a scenario where a tooltip is not hiding when another tooltip is shown, and here is a dojo for reference.

If you move your mouse up and down the colors, the tooltips show and hide as they should. If you stop on a color, move the mouse right into the tooltip, then straight back out of the tooltip and back into the color for that tooltip, then move the mouse up or down over another color, the first tooltip doesn't hide. You can repeat this sequence for the other tooltips as well, resulting in multiple tooltips showing.

Here is a jam so you can see what I mean as well. You can't see the mouse move, but you can see the multiple tooltips.

Hello,
I used the following approach for binding Kendo Gantt data source to local java-script array.

var dataSourceArray = [{...}, {...}, ...];
var fieldsObject = {id: { from: "id", type: "string", defaultValue: function () { return kendo.guid(); } }, parentId: { from: "parentId", type: "string", defaultValue: null }, start: { from: "start", type: "date" }, end: { from: "end", type: "date" }, title: { from: "title", type: "string" }, percentComplete: { from: "percentComplete", type: "number" }};
//we have pre-filled java-script array and fieldsObject
//define Kendo Gantt data source

var _dataSource = new kendo.data.GanttDataSource({

            schema: {
                model: {
                    id: "id",
                    fields: fieldsObject
                }
            },
            transport: {
                read: function (e) {
                    e.success(dataSourceArray );
                },
                create: function (e) {
                    if (e.data.models && e.data.models.length > 0) {
//...

                        }
                    }
                    else {
                        //...
                    }
                },
                update: function (e) {
                    if (e.data.models && e.data.models.length > 0) {
//...

                        }
                    }
                    else {
                        //...
                    }
                },
                destroy: function (e) {
                    if (e.data.models && e.data.models.length > 0) {
//...                       
                    }

                    }
                    else {
                       //...
                }
            },
            change: function (e) {
                if (e.action == "add" || e.action == "remove") {
                   //...
                }
                if ((e.action == "itemchange" || e.action == "remove") && (e.field == "percentComplete" || e.field == "start" || e.field == "end")) {
                   
                    }
                }
            }
        });

//Then Kendo Gantt is created

_kendoGantt = $("#gantt").kendoGantt({
                toolbar: [
{ template: kendo.template($("#headerTemplate").html()) }
                ],
                pdf: { fileName: $scope.selectedGantt },
                dataSource: _dataSource,
                dependencies: _dependencies, //also defined above in the code
                columns: _leftCols, //also defined above in the code
                views: [{ type: "day", selected: _ganttSettings.Timescale == "day" ? true : false }, { type: "week", selected: _ganttSettings.Timescale == "week" ? true : false },
{ type: "month", selected: _ganttSettings.Timescale == "month" ? true : false }, { type: "year", selected: _ganttSettings.Timescale == "year" ? true : false }],
                listWidth: _listWidth,
                showWorkDays: !_showWeekends,
                dataBound: _onTaskDataBound,
                moveStart: _onTaskMoveStart,
                resizeStart: _onTaskMoveStart,
                save: _onTaskSave,
                remove: _onTaskRemove,
                navigate: _onTaskNavigate,
                add: _onTaskDependencyAdd,
                change: _onTaskChange,
                edit: _onTaskEdit,
                height: _gHeight
            });

function _onTaskEdit(e) {
if(e.task.id){
//....
}
};

This code worked perfectly in version of Kendo UI v2016.3.1118, but it does not work in version v2021.2.616.

Using this code in version v2021.2.616 does not display any tasks in Kendo Gantt.

If I bind data source to local java-script array directly in Kendo Gantt constructor (dataSource: dataSourceArray), it displays tasks, but task does not have valid "id" (it is null) in event _onTaskEdit (when I double click task for editing). In this case id field must have string value according to: id: { from: "id", type: "string", defaultValue: function () { return kendo.guid(); } }

Your examples in documentation do not show how to provide custom data source schema while binding to local java-script array.

How do I provide custom data source schema while binding to local java-script array and make code above working for version v2021.2.616?

Im trying to display a kendo.grid after clicking submit. I attached a screenshot so you can understand what Im trying to do.

After filling in the information and click submit, I want the information to be displayed below but unfortunately nothing change after I click submit. Only the content in else is displayed

This is my code in view

<script>
$(document).ready(function () {
    $("#form").kendoForm({
        validatable: { validationSummary: true },
        orientation: "horizontal",
        formData: ...,
        items: ...,
        submit: function (ev) {
            $.ajax({
                type: "POST",
                url: RootUrl+"Issue/ReportIssue",
            });
        }
    });
    $("#grid").kendoGrid({
        dataSource: {
            data: [
                @if (ViewBag.ReportResult != null)
                {
                    foreach (var item in ViewBag.ReportResult)
                     {
                        @: { col1: '@item.ISSUE_NUM', col2: '@item.PRIORITY', col3: '@item.MODULE', col4: '@item.DESCRIPTION', col5: '@item.REPORTED_DATE', col6: '@item.ISSUE_RESOLUTION', col7: '@item.RESPOND_DATE', col8: '@item.ACTION_TAKEN', col9: '@item.RESOLVED_DATE', col10: '@item.STATUS' },
                     }
                } else
                {
        
                        @: { col1: 'fdfd', col2: 'fd', col3: 're', col4: 'gf', col5: 'hg', col6: 'hy', col7: 'hg', col8: 'jh', col9: 'yt', col10: 'hg' },
                }
            ],
            pageSize: 10
        },
        sortable: true,
        pageable: ...,
        groupable: true,
        filterable: true,
        // columnMenu: true,
        reorderable: true,
        resizable: true,
        selectable: "multiple, row",
        columns: ...
    });
});

Here is my controller. I commented a line in the sql statement(line 24 from bottom). Just ignore that as I dont want to carry two problems at the same time.

    public ActionResult ReportIssue()
    {
        if (Session["User_Name"] == null)

            ViewBag.ReportResult = null;
            

            SetUserViewBag();

            return View();

    }

Hi,

I have following situation:

We have desktop application and web application with angularJS and Kendo UI jquery which both use same server REST API. 

If user enters malicious code as string <script>alert("security breach")</script> through desktop application or manually through postman and API, this is saved to the database (we have cases where we have to allow such tags in db). When this is rendered on desktop, it is fine, but when I render Kendo UI tree list - script is rendered and executed.  So, my tree list is displayed, and alert is executed.

I have ngSanitize turned on application wide, but it seems not to be working on kendo ui widgets used within (we combine jquery and angular approach for widgets).

Do you have any suggestions how to approach to this? 

Thank you

Hello, I'm using some kendo grids in my application. i need to make them WCAG 2.1 AA compliant.

I use the wave plugin for chrome to see if there are any WCAG errors and its reporting that I have broken aria references on my grid page footer.

this is only happening on some grids so i believe its a setting to do with the grid or the page footer. 

this also happens on your basic demo of the grid

https://demos.telerik.com/kendo-ui/grid/basic-usage

but not the grid overview

thanks in advance
