Hello,

Is there a way to restrict kendo combobox being edited manually but only allow the user to select from the dropdown values. If yes would you give an example in razor please?

I also want to allow the user to edit to a valid date in a kendo datepicker but not any other text. Is that possible?

Thanks

I have a kendo grid with a column that has a row template that is a checkbox. When it is selected, it marks that row as selected so that I can operate on a subset of the rows selected by the user.

I wish to place a checkbox in the column header that will check or uncheck every row in the grid.

I have tried adding a headerTemplate with a checkbox but I do not know how to cause it to select all rows.

Also, for some reason the checkbox in the header does not get checked when I click it, instead when I click it, it appears to try to sort the grid (the asc/desc arrows appear on the header cell). I've tried adding `filterable: false` but this still happens.

My grid is below. The column in question is `select_all`

    <div id="PatrolRecords"
            data-filterable='{ "mode": "row" }'
            data-role='grid'
            data-sortable='true'
            data-detail-template='patrolDetailTemplate'
            data-detail-init='detailInit'
            data-bind='source: reportData, events: {excelExport: excelExportHandler}'
            data-bound='onDataBound'
            data-pageable='{ "pageSize": 10 }'
            data-toolbar='[{ template: kendo.template($("#toolbarTemplate").html()) }]'
            data-excel='{ "fileName": "Patrols.xlsx", "allPages": "true" }'
            data-columns='[
                {
                    field: "address",
                    title: "Address",
                    template: kendo.template($("#addressTemplate").html()),
                    filterable: { cell: { operator: "contains" } }
                },
                {
                    field: "end_date_seconds",
                    title: "Date & Time",
                    template: kendo.template($("#dateTemplate").html()),
                    filterable: false
                },
                {
                    field: "patrolled_by",
                    title: "Patrolled By",
                    filterable: { cell: { operator: "contains" } }
                },
                {
                    field: "select_all",
                    width: 35,
                    headerTemplate: "<input type=\"checkbox\" id=\"chkAll\" />",
                    template: "<input type=\"checkbox\" class=\"check_row\" />",
                    filterable: false
                }
            ]'>
        </div>

 

I checked the documentation for the API and am utilizing the open method

However when opening the calendar popup this way the keyboard navigation no longer works.  The only way to select a date seems to be via mouse click.

 

The issue is re-creatable on the demo example below

https://docs.telerik.com/kendo-ui/api/javascript/ui/datepicker/methods/open

I have found I can programatically set a kind of focus using the code

setTimeout(function () {
                 var ev = $.Event("keydown");
                   ev.keyCode = 39;
                      $("#FromDate").trigger(ev);
}, 100);

 

But after this the keyboard navigation is still not active.

Is there a way to make this work?

 

 

I have added some fields with caption names like this:
location: { caption: "Butik" }
but the problem is that its not used for grouping
it seems like a bug to me, is there way around it?

     Hi team,

 

The edit zone of the view html dialog does not fit the width of that dialog and cannot be resized.

 

Best regards.

How to truncate chart title if text is too long also once text is truncate show full text on mouse over or show in tooltips.

Hello,

 

after upgrading my Gantt chart to release 2020 R3 SP1 I noticed a significant performance drop in the chart to the point of it not being snappy enough to give to end users. I have made a simple repro at https://dojo.telerik.com/OjOCEjIm/4 (I hope this links to my custom edit, if not the code is down below to copy paste into a Dojo window). It is a simple Gantt chart where I add 50 summary tasks and 50 child tasks for those. 

 

When running the chart in the dojo under 2020 R2 SP1 the chart loads fast and clicking open a summary task has an almost imperceptible delay. But when switching to 2020 R3 or R3 SP1 releases from the dropdown in the top left, the same chart takes multiple seconds to load and opening of a summary task takes about 1-2 seconds.

 

I'm in a situation where the data to be displayed in the Gantt sometimes is in the order of 35-50*35-50 tasks. Are there any performance hints I might employ to make the R3 release usable as I would like to use for example the columnMenu option that I believe is only available in R3? Also any and all performance hints are welcome.

 

If the link up doesn't link to the custom Dojo, here is the code to copypaste:
