My mobile app build with kendo ui failed user acceptance testing because the app is "slow", "sluggish" or "sometimes stops working". After some research I found out that the app quite often fails to react when the user clicks a button: the click event does not fire when the user does not tap "the right way". Since my app aims at inexperienced users, this is a serious issue.

The problem can easily be reproduced in the button/events demo, especially when viewed on a mobile device:

http://demos.telerik.com/kendo-ui/mobile/button/events.html

Just between touching and releasing move the finger or mouse a little bit to the side or up/down, and the click event does not fire.

What's worse (and why i would consider this an error) is that the user gets a visual feedback that the button was pressed --- but nothing happens!

It's kind of like the opposite of the problem in this thread: http://www.telerik.com/forums/button-click-event-firing-when-trying-to-scroll where someone is (ab?)using oversized buttons.

Is there a way to set the sensibility of how much wiggle is allowed until a touch isn't a click anymore? Any other solution?

I am using kendoui.complete.2013.3.1119. The behaviour was tested on iOS6 & iOS 7 (iPad).

Hello,

A defect is preventing the sparkline tooltips from showing in the official release (v. 2013.3.1119) .
This issue is fixed in internal build v. 2013.3.1121 and later.

Recommended temporary workarounds:
  • Disable shared tooltips. This will not negatively affect Sparklines with only one series.

    $("#hum-log").kendoSparkline({
        type: "area",
        data: [71, 70, 69],
        tooltip: {
            format: "{0} %",
            shared: false
        }
    });
  • Set series names on Sparklines with more than one series:

        $("#sparkline").kendoSparkline({
          type: "area",
          series: [{
            name: "Series one",
            data: [71, 70, 69, 68, 65, 60, 55, 55, 50, 52]
          }, {
            name: "Series two",
            data: [73, 72, 72, 71, 68, 63, 57, 58, 53, 55]
          }],
          tooltip: {
            format: "{0} %"
          }
        });
Apologies for the caused inconvenience.

Is there a way to allow user to edit connections path by interacting with points? Or is possible to make the connections does not passing through shapes? 

 

The "editable" option just allows user to change the start and end of connection, not the path, I need to allow user to change the path because Kendo Diagram does not has an option to prevent connections of passing through shapes.

Example: https://dojo.telerik.com/@rodrigo_x10/AGExALED

 

You can see that connection between 1 and 3 is passing through Shape 2, which is a bad visualization of data.

 

Edit:

- Each shape has specific connectors (they dont change)

- Each connection is a link between a specific connector to another specific connector (so cant ignore this option and let kendo change the start and end connector)

- What I want is allow the user to change the path of the connection without changing the start or the end

- I can add points to connections, but they are fixed, the user cant interact with points.

Hi Team, 

 

In the demo example here, for kendo-angular-ui, we have an option to make summary of intermediate data, like for Q1, Q2 etc. 

Is there a similar option for the ui-jQuery version also. It will be great if you can point me to the doc for this. I see that there are not many option available for waterfall charts or i'm not seeing the right doc ?.

If there are other features as well for waterfall ui-jquery, kindly indicate them.

 

Thanks,

Chetan

Hello,

How can I get the text and the value of the button pressed?  Right now it only appears to return the value which is not what I want the user to see.  Like in this example it should say option 1 when you click on option 1 and not show value 1 but pass it back for use in the code.

https://dojo.telerik.com/OkoCIxIT

How can I get this to work properly?

Thanks -Tim

Hi Admin and Everybody,

As the title, Currently I have read all data from the folder to the corresponding items of folder. But data children ( see picture 1.png ), can not call the function.

When I clicked delete from folder name, it work and can log name

But when clicked delete from items inside folder, it cannot call function, not error in console debug.

My code will show you:


$("#filemanager").kendoFileManager({
    dataSource: {
        transport: {
            read: function (options) {
                var that = this;

                $.ajax({
                    url: "/_layouts/15/xxx/API/ApiHandler.ashx?tbl=like&func=getalllibrary",
                    dataType: "json",
                    method: "POST",
                    data: that.parameterMap ? that.parameterMap(options.data, "read") : options.data,
                    success: function (result) {
                        options.success(result);
                    }
                });
            },
            delete: function(options) {
               //Test call function delete when click delete

               var text = options.data.name;
               console.log(text);

               //result: can log folder name but cannot log items name inside folder
               
            },
        },
        schema: {
            data: 'data',
            model: {

               id: 'path',  

               children: 'items'  
            }
        }
    },
    toolbar: {
        items: [
            { name: "custom", type: "button", text: "Create", command: "MyCustomCommandCreate" },
            { name: "custom", type: "button", text: "Upload", command: "MyCustomCommandUpload" },
            { name: "sortDirection" },
            { name: "sortField" },
            { name: "changeView" },
            { name: "spacer" },
            { name: "details" },
            { name: "search" }
        ]
    },
    contextMenu: {
        items: [
            { name: "rename" },
            { name: "delete" },
            { name: "custom", text: "Detect", command: "MyCustomCommandDetect", spriteCssClass: "k-icon k-i-info" }
        ]
    },
    draggable: true,
    resizable: true
});

My json data has a structure similar to that of demo from docs Kendo ( https://docs.telerik.com/kendo-ui/api/javascript/ui/filemanager/configuration/datasource ) - EXAMPLE

Image show you my Json Data inside url link: ( 1.png )

Looking forward to hearing from Admin and everybody soon, thanks

Hi,

we want to persist the width of resizable columns, only.

We are aware of this article (https://demos.telerik.com/aspnet-mvc/grid/persist-state) and the getOptions() and setOptions() functions, but these get/set other options like sort and page.

We only want to persist the column width. Is there a supported way of doing this?

Kind regards.

Hi, I've been trying for quite some time now to expand the newly created row. So basically when I hit "add new" and hit update after it updates and inserts, then expand that new row.
