Questions on Kendo UI for jQuery Forum

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).

TIA Marco

Important: Tooltips not visible in Q3'13 release

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 keep connectors visible even without hover the diagram shape?

Get the example diagram in https://dojo.telerik.com/oNOJidug from example in Diagram Connections page reference

With the basic configuration:

$("#diagram").kendoDiagram({
    shapes:[
      {
        id:"1",
        content:{
          text: "State 1"
        },
        x: 20,
        y: 20
      },
      {
        id:"2",
        content: {
          text: "State 2"
        },
        x: 300,
        y: 20
      }
    ],
    connections:[
      {
        from: "1",
        to: "2",
        content: {
            text: "Step 1"
        },
        stroke: {
            color: "#33ccff"
        }
      }
    ]
  });

My question is, is there a way to keep the connectors of both shapes visible without need to keep mouse hover?

I want this:

instead of:

Chart with negative value

hi team, I want to show a chart with some negative values, ( and also positive values). However, I found that the xaxis labels are always under the line y=0. I do not want them appear in the chart, instead, I would like to show label in the bottom to the chart. I notice in your demo:

categoryAxis: {
...
labels: {
padding: {top: 145}
}
},

than the padding parameter can set the xaxis label's position. However, since my data is dynamic, I do not know how distance I should padding. Is there a way to automatically determine the position of xaxis label to the bottom?

</Schema>

If I use Saiku, everything works: I can see all dimensions and all levels. (you can see it in the image below on the left).

Instead, if I use PivotGrid, I see fields but not levels. When I try to drill down fields, I continue to see the field endlessly. (An example in the image below)

There are no errors in the logs.

Anyone have ideas/suggestions?

Thank u.

Angular Chart Reclaculate CategoryAxis labels step after zoom

Hello

I have an Angular column chart. On render event, I calculate the CategoryAxis labels steps. Then after zoomEnd event, I get new (current) categories and according to them, again I recalculate the CategoryAxis labels steps to have new steps(distance) for labels.

The question is, that after setting the new step size, the chart initialized again with "0" levels zooming. I mean after setting the new steps I lose my zoomed stage.

Thanks in advance

How to make reload all value then return step 1

Sorry My Title maybe something went wrong. It means. After click done, deleting all values and returning it to step 1 to perform new action.

This code I have taken from https://demos.telerik.com/kendo-ui/wizard/ajax

How to Upload Image and Show Image in Kendo Wizard

Hello, I have some problem when use Kendo Upload + Kendo Wizard.

Specifically I'm doing a Kendo Wizard with an .html file.

In the .html file of step 1, I used Kendo Upload to Upload Image.

Then It will show up in the .html file of step 2. But now I can only show in step 1 and I don't know how to show it in step 2

Please help me, thanks!!!

My Kendo Wizard Code:

$("#wizard").kendoWizard({
        loadOnDemand: true,
        reloadOnSelect: false,
        steps: [
            {
                title: "Upload",
                icon: "upload",
                successIcon: "check",
                buttons: ["next"],
                contentUrl: "./step1.html"
            }, {
                title: "Settings",
                icon: "gear",
                successIcon: "check",
                contentUrl: "./step2.html"
            }, {
                title: "Check All",
                icon: "preview",
                successIcon: "check",
                buttons: ["previous", "next"],
                contentUrl: "../content/web/wizard/ajax/ajaxContent4.html"
            }, {
                title: "Save",
                icon: "save",
                successIcon: "check",
                buttons: ["previous", "done"],
                contentUrl: "../content/web/wizard/ajax/ajaxContent4.html"
            },
        ],
        done: function (e) {
            e.preventDefault();
            var form = $("form").getKendoForm();
            var zxy = $("#title").val();

            console.log(zxy);

            if (e.sender.stepper.steps()[1].options.error) {
                e.sender.stepper.steps()[1].setValid(true);
                e.sender.stepper.steps()[2].setValid(true);
            }

            kendo.alert("Thank you for registering!");

        },

        reset: function () {
            var form = $("form").getKendoForm();

            if (form) {
                form.clear();
            }
        }
    });

My step1 is Kendo Upload

<inputname="files"id="files"type="file"/>

$("#files").kendoUpload({
        async: {
            chunkSize: 11000,// bytes
            saveUrl: "https://demos.telerik.com/kendo-ui/upload/chunksave",
            removeUrl: "https://demos.telerik.com/kendo-ui/upload/remove",
            autoUpload: true
        },
        validation: {
            allowedExtensions: [".jpg", ".jpeg", ".png", ".bmp", ".gif"]
        },
        success: onSuccess,
        showFileList: true,
    });
    function onSuccess(e) {
        if (e.operation == "upload") {
            for (var i = 0; i < e.files.length; i++) {
                var file = e.files[i].rawFile;
                if (file) {
                    var reader = new FileReader();
                    reader.onloadend = function () {
                        $("<div class='product'><img src=" + this.result + " /></div>").appendTo($("#products"));
                    };
                    reader.readAsDataURL(file);
                }
