I have grid validations that I catch/build in the Error event ... how can I pass my validation from the Error event to a detail row? I expand the detail row automatically when an error occurs.

Hello,

I'm fairly new to Kendo ( still testing it for my mobile app ) and i'm trying to display your list of friends (pulled from FB) in a scroll view with their names and pictures. It can go up to 1K + Friends and when switching from a profile to another, the list of friends has to be re populated. I can't have it work, and I'm a bit worried about performances when listing 1000+ friends on the page.

So Basically, I have a ScrollView that I'm trying to rebuild (or at least remove the old data and add new data) when a user get back to the previous page and come back again to this page. It's like a profile page. When you go there for user id = 1 you have some information and a scrollview with his friend's name and pictures, and when I go to another user (id = 2) then I want to change every information on the page, including the information bound in the scrollview.

From what I understand, one can only change the pictures of the scroll view by initiating the view. It doesn't seem to work when data-show is triggered and I have a feeling that we should re-initiate the page completely... Am I right ? Doing the scroll view methods such as SELECTOR.data("kendoMobileScrollView").setDataSource(friendsToInvite) or scrollview.refresh() doesn't seem to work.
Am I doint something wrong or should I re initialize the view everytime a user go back and forth on the different user profiles ? How can I do this ?

here is my HTML:



and My JS:



All that is commented is something I've tried. whithout success.Also, you'll notive that I've filled the scroll view twice: once for the "initialization" with empty data and another one with the data I want to use. The fact that the when() method delay the construction of the scroll view makes it bug. I don't know why.

Hello, Kendo-Team.
I have a question about complex JSON responses: Say, I get  a response like this and want to use this data for creating a Grid:


so how should I use <code>dataSource.schema</code> and/or <code>kendoGrid.columns</code> properties to get size.bytes and/or mtime.UTC ? How to correctly parse this type of DATETIME info via JS ? Templates ?

I only know, I should use <code>dataSource.schems.items</code> to point out the Array with objects (in my case it's "items")


without defining any columns, I get size and mtime columns with [object Object] in it.

I am passing a value from a param from a click event, which works fine;

 <a data-bind="events: { click: roomselect }"  data-target="detailPane">#: desc# </a>

 but I want to get this value to another method within the view-model. I was trying to use "set " but it does not assign the value.  

(I am trying to get the value to the line  in the method init below: url: "http://myURL/api/room/" +  this.roomSelected + "/children",)


 RoomsViewModel = kendo.data.ObservableObject.extend({
        roomsDS: null,
        roomDS:null,
        roomSelected: null,
        
        roomselect: function(e) {
            var that = this;
            that.set("roomSelected", e.data.id);
        },     

        init: function () {
            var that = this, roomDataSource;
            kendo.data.ObservableObject.fn.init.apply(that, []);                 
            roomDataSource = new kendo.data.DataSource({
            
            transport: {
                read: {
                    url: "http://myURL/api/room/" +  this.roomSelected + "/children",
                    dataType: "json",
                    type: "GET"
                },
.......

Documentation on PanelBar has a dataSource option in the constructor configuration

http://docs.telerik.com/kendo-ui/api/web/panelbar#configuration-dataSource

However the TypeScript definition does not contain this choice:

interface PanelBarOptions {
        name?: string;
        animation?: PanelBarAnimation;
        expandMode?: string;
        activate?(e: PanelBarActivateEvent): void;
        collapse?(e: PanelBarCollapseEvent): void;
        contentLoad?(e: PanelBarContentLoadEvent): void;
        error?(e: PanelBarErrorEvent): void;
        expand?(e: PanelBarExpandEvent): void;
        select?(e: PanelBarSelectEvent): void;
    }

How does one know if the kendo files one is using in AppBuilder are up to date?  And if one finds out they are out of date, how would one update them?  The reason I ask, most posts in the forums and all references on kendoui.com speak of release by quarter, eg. Q3 2013.  But the versions in the files themselves are in this format: v2013.1.621.  Is the "1" the quarter?

Thank you,

I have observed that drawer animation becomes "jumpy" if view performs a lot of data loading and binding on show. As a way around it, I am building postponing any heavy duty processing until the animation is completed.

I am using deferred promises to watch for the transition to complete using the following. Here's a question: is there a way to do it?

After I build a theme for DataViz in the themebuilder what do I do with the JSON that I am able to generate?  When I click on the button in theme builder that says "What do I do with this?" it just tells me about how to replace the css for the web themes... 

So if I want to globally change my dataviz themes how do I do this using the theme builder?

Thanks,
Jason

I updated to the newest kendo release yesterday and I've noticed that the loading graphics (i.e. app.application.showLoading();) have changed on android, but not on iOS. I like the graphics on iOS, where the motion icon is centered over the app. Android displays a dark translucent sheet over the entire app. It looks bad. How can I get rid of it?
