Your example of pie chart remote data binding works great when the web service is hosted in the same place as the HTML, but it seems to be erratic if the web service is hosted somewhere else.

What I did was create a WCF service that returns a JSON object exactly like your example web service, and then call it with your exact HTML.

Reproducing the error is simple:  take  the pie chart remote data binding example and change the web service address so it's hosted in a domain different to the HTML. Obviously, you need to change to JSONP and add the callback function.

Thanks.

I wasn't able to find a chart title option for a gauge as with the other charts. If this isn't an option are there any recommendations on how to match and overlay the existing style of a chart title onto a gauge?

I have several sparklines in my HTML and they're being populated by a web service. It seems that they don't always fill out; I refresh and a few fill out, I refresh again and others fill out. The only way I've been able to fill them all out is by displaying an 'ALERT' for every function called. It seems it's a problem with a refresh.

Is it possible that I'm calling the web service too many times and it has become erratic?
Here's the code:

I have a simple grid that contains a column designated to allowing the user to browse to a directory using the default file chooser. This column is instantiated by the following command, and appears properly when the page is rendered:

(note: this grid has been isolated down to just the problem column. testData is just an array of a few rows of example data.)
$("#grid").kendoGrid({
    dataSource: {
        data: testData,
        pageSize: 10
    },
    groupable: false,
    sortable: false,
    pageable: {
        refresh: true,
        pageSizes: true
    },
    columns:
    [
 
       {
           field: "FileName",
           title: "File Name",
           template: "<input id='f', type='file' />"
       }
    ]
});
As shown in the code, the input type of is "file," which defaults to a textbox/browse button that opens a file picker window. I decided to use this instead of writing one on my own. The menu button that generates a new row is created with this code:
<div id="menuTest">
    <ul id="menu">
        <li onclick="javascript:$('#grid').data('kendoGrid').addRow()"><img src="Images/help_videos_16x16.png"/>New</li>
    </ul>
</div>

 When the button is clicked, a new row is successfully generated. All of the columns show up properly, but the FileName column shows up with a large white textbox instead of the gray box/browse button that is shown on the initial render. It also will not allow me to spam the new button, because in order for another new row to be generated, some sort of data has to be entered into the blank textbox (it can be a string, int, char, whatever). This data then disappears, and it defaults to the gray textbox/browse button after the new button is hit again. 

Attached is a series of screenshots of me stepping through the UI. The screenshots show:
1) The column on the initial render
2) The column after "new" is hit once (showing the large blank textbox)
3) The column after hitting "new" again (without entering anything into the textbox)
4) The column after entering a string into the white textbox and then hitting "new" again. Note that this brings us back to image 1, only with a new viable row added.

Is there a way to alter my code to prevent the white text box from appearing? Perhaps I need to assign some sort of default value, or should I scrap this approach?

I have chart that all values are integers. It display labels well when value is quite big. e.g. it display 2,4,6,8,10. So it calculates vaues nicely. But with small values on report e.g. 1, 2, chart display also values like 0.5, 1.5, 2.5
I would like to ask how to set chart to set minimal possible gap would be e.g 1.

I need to show confidence intervals on a chart that is showing some forecasts (80% and 95% intervals). Something like what can be done with the Percentiles plugin for Flotcharts (http://www.flotcharts.org/flot/examples/percentiles/index.html).

Is there any way to do this using DataViz (aside from drawing 5 separate line series)?

Cheers,
James

The Kendo Mobile Q2  2013.2.716 release includes drastic changes to the km-loader for iOS. There is no longer the translucent, black rounded-corner box with a white spinner KendoUI font. Now the entire screen is slightly dimmed with a gray progress indicator and is not very visible when an app uses dark styles. The markup has also changed from previous versions.
<div class="km-loader" data-role="loader" style="display: none;">
  <span class="km-loading km-spin"></span>
  <span class="km-loading-left"></span>
  <span class="km-loading-right"></span>
  <h1>Loading...</h1>
</div>
Here are my style overrides for the new classes to display a white spinner and text. Is there a setting to do this otherwise or better yet use the previous loader styles in the new release?
.km-ios .km-loading { background-color:#FFF }
.km-ios .km-loader .km-loading-left { background-color:rgba(255,255,255,0.55) }
.km-ios .km-loader .km-loading-right { background-color:rgba(255,255,255,0.2) }
.km-ios .km-loader h1 { color:#FFF; text-shadow: 0 1px 0 rgba(0, 0, 0, 0.8); }

Go to the demo site http://demos.kendoui.com/web/grid/index.html, drag two columns for grouping and collapse all items.
The second group shifts to the right in IE9. Have to put it in compatibility mode for it to work.
Please provide a workaround or a fix for this.
Thank you.

So for those of us like me who might want to just try this thing out as a FullCalendar.js replacement (just viewing a month of events at a time, no edit feature, purely just displaying information

Umm seems that the scheduler doesnt actually let you turn editable off.

I didnt set any update/remove transport paths, etc. but I would assume that by turning editable off the user would lose the ability:

 to delete the item
drag items around the calendar
open the edit window (maybe theres a secondary window that just lets you view the information)

my assumption of course is, if we have the ability (at least in writing) to turn off the editability of the controller, that it should show that and not let people try and delete items?

I currently have a grid that is bound via an Ajax call. The model is a List<Objects> for the view. I have a button that on click I would like to pass the selected data grid object to a different controller/action. 

I have tried to do a Ajax Post however the response is HTML but it does not get rendered to the browser.

Is there an easier way to do this? 

Thanks,
