Hi,
I'm working with datepickers and I tried the following a while ago:

$("#begin_date").attr('disabled','disabled');

I tried this to disable the text input of a date. But I realized later that it also makes the attribute unavailable for the web server to use in my application. The server wasn't receiving the dates I was picking so I stopped using it.

Is there anyway to disable that text input besides this method?

I use a Kendo Sortable in 3 different places in my app. It has always worked flawlessly for me however recently I upgraded to Kendo 2019.1.115 and ONE of the kendo sortables has stopped working correctly.  I know the issue isnt kendoSortable since its working fine elsewhere. 

 

Here is the behavior I have seen. Before the drag begins this is what I have

Now if I drag Chilly to below Fresh Lemon I end up with the following

https://screencast.com/t/8UDK6LKmANK

The item that was dragged appears twice at the end of the list. I wrote out the source in the change event and it is correct. It shows 

https://screencast.com/t/JTcjSE7aj80h

As you can see the data is correct. The problem is that the kendoSortable isnt showing what is in the data model.

Here is my code and template:

<script type="text/x-kendo-tmpl" id="tmplMenuOptionsGroupRow">
    <div class="d-flex optionRow">
        <div class="pl-2 col-1">
            <i class="fal fa-arrows fa-2x dragHandler"></i>
        </div>
        <div class="col-5 modifierDesc">
            <input name="optionDesc" class="form-control k-textbox k-input-lg"
                data-bind="value: description, disabled:legacy, events:{change: editorModel.menuOptionGroup.onMenuItemOptionsGroupChange}" />
        </div>
        <div class="col-4 optionPrice dragHide">
            <input class="k-input-lg" data-role="numerictextbox"
                data-format="c"
                data-min="0"
                data-format="c2"
                data-spinners=false
                data-bind="value:price, disabled:legacy, events:{change: editorModel.menuOptionGroup.onMenuItemOptionsGroupChange}" />
                 
        </div>
        <div class="dragHide optionDelete col-1" >
            <button type="button" class="btn btn-danger btn-sm" data-bind="click:editorModel.menuOptionGroup.deleteOption, disabled:legacy"><i class="fal fal fa-trash-alt"></i>
            </button>
        </div>
    </div>
</script>

 

$("#optionGroupItems").kendoSortable({
    cursor: "move",
    holdToDrag: false,
    autoScroll: true,
    ignore: 'input, button',
    handler: '.dragHandler',
    // move: function (e) {
    //     console.log('moving');
    // },
    placeholder: function (element) {
        console.log("placeholder");
        return element.clone().css({
            "opacity": 0.3,
            "border": "1px dashed #000000"
        });
    },
    hint: function (element) {
        return null;
 
    },
    change: function (e) {
        console.log('drop/change');
 
        var oldIndex = e.oldIndex;
        var targetIndex = e.newIndex;
 
        console.log('BEFORE Update');
        _.each(self.editorModel.menuOptionGroup.options, function(anOption){
            console.log(anOption.description);
        });
 
        self.editorModel.menuOptionGroup.options.splice(targetIndex, 0, self.editorModel.menuOptionGroup.options.splice(oldIndex, 1)[0]);
        //after the splice
        console.log("");
        console.log('AFTER Update');
        _.each(self.editorModel.menuOptionGroup.options, function(anOption){
            console.log(anOption.description);
        });
         
        // console.log(self.editorModel.menuOptionGroup.options);
    }
});

Hi,

Are there any hard or soft limits on maximum number of rows/columns?  I'd expect performance to degrade at some point, especially when sorting and filtering, just curious if there are known limits as to what those might be.

Hi,

 

Seems many links in "how to " sections are broken, like : https://docs.telerik.com/kendo-ui/controls/data-management/grid/how-to/Editing/using-mutiselect-editor-for-comma-separated-string

Alwas getting to knowledge base, mostly unusable.

Please advise.

Thank you.

 

Best regards,

Hello,

 

In order to preserve editing mode in the grid after a server side error, I use the methode explain here : http://blog.codebeastie.com/kendo-grid-error-handling/

It seems to work, but after an error, if the user modify the data in the grid and save again, the same data (before modifications) are send again to the server.

I'm using inline editing and MVVM.

 

The data source :

var remoteDataSourceContrats = new kendo.data.DataSource({               
    transport: {
        read: ...,
        update: ...,
        create: ...,
        destroy: ...
    },
    error: function(e) {
 
        console.log(e);
         
        $('#listeContrats').data('kendoGrid').one("dataBinding", function (x) {
            x.preventDefault();
        });  
    },
    batch: false,
    pageSize: 20,
    schema: {
        data: "contrats",
        model: ...
            }
        }
    }
});

 

The error response :

{ "errors": ["Erreur de modification"] }

 

What am I doing wrong ?

I have a grid which contains an adres ticket, some adresses contain a special character like ' 

When I want to get the data from the item when I click an icon on the record, I don't get the correct data:

This is my javascript to load the grid (it is placed in a div)

function loadConnectionsGrid() {
        connectionsGrid = $("#connectionsGrid").kendoGrid({
            selectable: "row",
            filterable: true,
            pageable: {
                refresh: true,
                pageSizes: [10, 20, 50, 100],
                buttonCount: 5
            },
            resizable: true,
            columnMenu: true,
            sortable: true,
            reorderable: true,
            columns: [{
                field: "EAN",
                title: "EAN",
                width: "140px"
            }, {
                field: "Discipline",
                title: "Discipline",
                filterable: { multi: true },
                width: '100px'
            }, {
                field: "StreetName",
                title: "Straat"
            }, {
                field: "PostalCode",
                title: "Postcode",
                width: '100px'
            }, {
                field: "BuildingNumber",
                title: "Huisnummer",
                width: '100px'
            }, {
                field: "BuildingNumberSuffix",
                title: "Toevoeging",
                width: '100px'
            }, {
                encoded: true,
                field: "CityName",
                title: "Plaats",
                width: "140px"
            }, {
                title: "&nbsp;",
                template: "#=selectAddressAction(data)#",
                width: '25px'
            }]
        }).data("kendoGrid");
    }

In my case it's about column Cityname (I already tries encoded: true as you can see)

When I click the icon on the record this function fires: 

 function initializeCreateConnectionModal(e) {

        $("#btn-create-and-assign").show();
        $("#btn-create-case").show();
        $("#createConnectionModal-success").hide();
        $("#createConnectionModal-error").hide();

        enexis.services.tablerecords.getData({ Tables: [{ Name: "ANL001" }] }, getAanleidingCallback);

        var item = $(e.relatedTarget).data('item');
        loadSelectedConnectionsGridData(item);
    }

 

 When I'm trying to get the item (the bold line) In this case I don't get an object with the data like Screenshot01.png

But I get a string (Screenshot02.png)

It would be great if there would be an IRC Channel for Community support as well since sometimes it can be way quicker than the forums. No idea how to manage subforums in IRC though ;) But for the community it would be really cool.

Hello,

I'm using Kendo JQuery Scheduler inside an Angular application and I have a problem with the native drag&drop when I specify a small eventHeight on the views.

On the code bellow, there is a problem when eventHeight is 20px.

01.this.kendoScheduler = kendo.jQuery(this.kendoSchedulerEl.nativeElement).kendoScheduler({
02.      date: new Date(),
03.      startTime: this.dayStartDateTime,
04.      endTime: this.dayEndDateTime,
05.      allDaySlot: false,
06.      views: [
07.        {
08.          type: 'timeline',
09.          title: translate['COMMON.CALENDAR.DAY'],
10.          eventHeight: this.eventHeight,
11.          columnWidth: this.dayColumnWidth
12.        },

Browser: Chrome

To be more specific, with eventHeight=20px, when I drag an event (see attached file) bellow the first 20 pixels of the target cell td, a tooltip appears and dropping the event doesn't trigger the datasource update event. I must drop it inside the first 20 pixels to make drag&drop work.

Do you know what could have gone wrong ?

Regards,

Nicolas
