I have created the following Dojo (modified from the Demo of Grid > Selection)
http://dojo.telerik.com/@esinek/IHaM

When I load the Run the page and click a row, the entire grid "jumps" (probably a scrollTo somewhere) so the top of the first row in the grid is at the top of the browser.  This is very distracting and confusing.  Is there something in my configuration that is causing this or is it a bug - and if it's a bug, is there a workaround?

If I change the "selection" option to "row" or remove the selection option, the jumping doesn't happen.

Note that the "jump" only happens on the first selection.  Subsequent selections don't cause the grid to "jump".

Thanks,

The tasks are placed in wrong date in the chart panel.

 

for example: the "T2" task has start date (20/10/2020) and end date (23/10/2020) but in the chart is placed in (6/11) - (9/11).

 

this is the configuration I used for rendering the component: 

kendo.jQuery(chartElement).kendoGantt({
    views: [{type: 'week', selected: true, slotSize: 30}],
    rowHeight: 10,
    toolbar: ['pdf'],
    listWidth: "0%",
    editable: false,
    selectable: true,
    tooltip: {
        visible: true,
        template: `#= task.tooltip #`
    },
    range: {
        start: new Date(this.model.startDate),
        end: new Date(this.model.endDate)
    },
    showWorkDays: false,
    workDayStart: this.model.startDate,
    workDayEnd: this.model.endDate,
    taskTemplate: `<div style="background-color: #= backgroundColor #; padding: 4px 8px; border-radius: 2px"> #= title # </div>`,
});

 

// this is how I added data into the chart

const dataSource = new kendo.data.GanttDataSource({
    data: this.listOfScheduleTasksForGanttChart.map(task => {
        const startDate = new Date(task[this.ganttChartTasksGridStartDate]);
        const endDate = new Date(task[this.ganttChartTasksGridEndDate]);
        return {
            id: task.scheduleTaskId,
            orderId: task.sortId,
            parentId: task.parentId,
            title: task.taskName,
            start: startDate,
            end: endDate,
            backgroundColor: task.backColor,
            expanded: true,
            tooltip: task.toolTip
        }
    })
});

Hi

I have custom columns defined for Grid table:

columns: [
{
field: "ID",
width: 50,
filterable: false,
attributes: {"data-test":'#=ID#'},
media: "(min-width: 900px)"
},
{
field: "IDstatus",
width: 50,
filterable: false,
attributes: {"data-status": '#=Status#'},
media: "(min-width: 600px and max-width: 900px)"
},

 

What I would like to do is to change 'Status" in attributes by taking out parts of code/text from it, but when I try to get this to work in this way:
attributes: {"data-status": '# var z = Status; var re = /<span.*?<\/span>/gm; z = String(z).replace(re, ""); # #=z#'},
… it throws "Invalid template" error.

I was trying to escape quotations, add quotations or remove them, even using non-regex replace but with no success.

Is it possible to just get "review" from this cell to fill in "data-status" attribute?

 

Status cell is rendered on PHP page as:
<td><span class="k-icon k-i-track-changes-enable"></span> review</td>

Thank you in advance for your reply,

Hello,

As a preface, I am quite new to the Telerik controls and developing web apps in general, so apologies in advance if there is an obvious or existing answer to this :)

I need to make a page for reserving meeting rooms, so a grid style view with room names down the left side, hours for columns and then things like showing existing bookings (which might overlap the hour columns), being able to click/drag on the view to select a room for a desired time interval etc.

The application I need to extend with this is mainly angular.js on the client side. I am hoping to accomplish this using angular style databinding in the view. 

I have been looking through the available Telerik components, and I would basically really like some guidance as to what component might be easiest to get to work in this fashion, to me it seems both the Schedular and the Grid might potentially make good starting points. 

If anyone knows of tutotials or examples that are similar to my usecase, that would be really nice as well.

I'm using Kendo's JQuery PDFViewer control to display PDF files inline in a web page. The control is launched into a modal popup via a piece of JavaScript, thusly:

 

var launchPDFModal = function (param1, param2, param3) {
        var pdfViewer = $("#pdfViewer").data("kendoPDFViewer");
        if (!pdfViewer) {
            pdfViewer = $("#pdfViewer").kendoPDFViewer({
                pdfjsProcessing: {
                    file: ""                 },
                width: "100%",
                height: "85vh",
                toolbar: {
                    items: [
                        "pager", "zoom", "search", "download", "print"                     ]
                },
                messages: {
                    defaultFileName: param1
                }
            }).data("kendoPDFViewer");
        }
 
        var pdfHandlerUrl = "/api/pdfViewer/" + param1 + "/" + param2 + "/" + param3;
        pdfViewer.fromFile(pdfHandlerUrl);
 
        $("#pdfViewerModal").show();
    }

The three params are used to identify the file to be shown and file is returned as a stream as the files are stored in data and not as files on a drive. I have verified the references to the Kendo library, pdf.js and pdf.worker.js are all correct as required.

The PDF file loads and displays just fine in the control. The download button also successfully saves the file to the local drive. However, when I click the print button, and the print preview shows up, it has the correct number of pages, but they are all blank. Trying the actual print, just prints blank pages. Browser doesn't matter. I've tried Chrome, Edge, and Firefox. Same thing. I've also verified that it's not an ad blocker (neither Edge nor Firefox installs have any plugins on them).

      var RegionalMappingDataSource = new kendo.data.DataSource({
            transport: {
                read: function(options) {
                    $.ajax({
                        url: siteRoot + '/Admin/RegionMapping/GetRegionMappings',

                },

                update: function () {
                    console.log("hello!");

                parameterMap: function(options, operation) {
                    if (operation !== "read" && options.models) {
                        return { models: kendo.stringify(options.models) };

Hi,

I am using Kendo Grid and I have created a checkbox that is read-only as default. The checkbox will only enable after user has edited the row.

I am developing this function in onChange by using "$('.chkbx').prop('disabled', false);" to remove the disabled attribute of checkbox but it will enable all the checkbox in the grid instead of edited row.

I have retrieved grid, recno and data item of current row in onChange. May I know is that possible to remove the disabled attribute of checkbox by using these information I retrieved? Or even better if could based on condition of dirty flag, so that if user has removed the value they changed, the checkbox can revert back to disabled. 

Thanks in advance.

Here is my code:

model: {
            id: "recno",
            fields: {
                DEupdateFlag: { type: "boolean" },
                recno: { editable: false, validation: { required: true } },
                custname: { editable: true}
            }
        }
         
         
columns: [
            {
                template: '<input type="checkbox" disabled="disabled" #= DEupdateFlag ? \'checked="checked"\' : "" #      class="chkbx" />',
                width: 70,
                headerTemplate: '<b>Action</b>',
                headerAttributes: { style: "text-align:center" },
                attributes: {
                    "class": "table-cell",
                    style: "text-align: center"
                }
            },
            { field: "recno", title: "Recno", width: 66, filterable: true },
            { field: "custname", title: "Customer Name", width: 85, editor: TextEditor, filterable: true }
        ]
 
function onChange{e){
    if (e.action == "itemchange") {
        var grid = $("#mainGrid").data("kendoGrid");
        var recno = e.items[0].recno;
        var dataItem = grid.dataSource.get(recno);
 
        $('.chkbx').prop('disabled', false);
        }
}

The switch's toggle() method doesn't fire the MVVM change event, nor does it update the viewModel property.

Setting the viewModel property obviously updates the viewModel property, but it too doesn't fire the change event.

Only clicking on the switch seems to fire it.

Both of the methods do change the visual state appropriately, and also end up changing the aria-checked value. Here is a dojo.

Is there a way to programmatically change the switch that also fires the change event?
