So, we're evaluating Kendo UI against Dev Express for our next version of Oliver.  Thought I'd test forum support as well!  

I'm having a problem getting my tree view to display folders (rather than the default >).  Probably something simple.  Here's the MVC wrapper - note it's a treeview in a panel:

@(Html.Kendo().PanelBar()
    .Name("panelbar")
    .ExpandMode(PanelBarExpandMode.Single)
    .Items(panelbar =>
    {
        panelbar.Add().Text("Folders")
            .Content(@<text>
            <div id="folderTreeView">
                @(Html.Kendo().TreeView()
                    .Name("treeview")
                    .DataTextField("text")
                    .LoadOnDemand(true)
                    .DataSource(source => 
                        source.Read(read =>
                            read.Action("GetFolders", "documents")
                        )
                    )
                    .Events( events => events
                        .Select( "onTreeItemSelect" )
                    )
                    .Deferred()
                )
            </div>
            </text>);
        panelbar.Add().Text("Batches").Content("Batches? We 'aint got no batches. I don't gotta show you no stinkin' batches!");
        panelbar.Add().Text("Clusters");
        panelbar.Add().Text("Tags");
        panelbar.Add().Text("Exemplars");   

    })
    .Deferred()
)
 
Here's the ajax handler:
        public List<DocTreeItem> GetFolders(int? id)
        {
            if (!id.HasValue)
                id = 0;

            List<DocTreeItem> folders = (from docFolders in _dataContextFactory.OliverDBContext.GetTable<FolderTree>()
                                            where docFolders.ParentFolderId == id 
                                            select new DocTreeItem()
                                            {
                                                id = docFolders.FolderId,
                                                text = docFolders.FolderName + " (" + docFolders.DocCount.ToString() + ")",
                                                hasChildren = docFolders.HasChildren,
                                                spriteCssClasses ="folder"
                                            }).ToList();
            return folders;
        }

where DocTreeItem is:
    public class DocTreeItem
    {
        public int id { get; set; }
        public string text { get; set; }
        public bool hasChildren { get; set; }
        public string spriteCssClasses { get; set; }
    }

What am I doing wrong?  Note, I have to define DocTreeItem instead of using Kendo.TreeViewItem because of a problem with camelCase:  If I return a list of TreeViewItems, kendo js is expecting them in camel case.  But, when I enable camel case via: config.Formatters.JsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); my grid controls break because the grid model binds to the non-camel case model definition, but when it goes to bind on the client, the ajax call now is sending camel case and so the grid won't find it.  How do you deal with that, also?

Thanks,

Robert

Since $.Browser is deprecated and $.Support doesn't appear to provide a check for supported content types, what's the best way to deliver device specific content types?

Here are some valid examples;
Flash based content to desktop systems, alternate content to iPads. (Please no flames on Flash, it still has valid uses).

Ad-hoc iPad app installs where you would need an install link for iPad and a download link for other browsers.

This is what I'm currently using;

var agentMatch = navigator.userAgent.match(/(iPhone|iPod|iPad)/);
 window.is_AppleMobile = (typeof(agentMatch) === 'undefined') || (agentMatch === null)?false:true;

Any thoughts?

Hello

I have script manager in my page and am using kendoGrid. I am connecting the grid to the service. When this code runs I get the following error:

I've checked the script manager code it is with the endWith, (String.prototype.endsWith=function(a){return this.substr(this.length-a.length)===a})

Thank you for your help

Does Kendo have a Tooltip plug-in that can be invoked from the grid cell, perhaps opening when the mouse has been in the cell for a specified duration, e.g. 750ms, and then closing when the mouse leaves the cell?

I am calling three kendo grids on a page. I am using web api to fill data in the datasource. Sometime (not all the time) one of my kendo grid does not load data for an unknown reason. I just see the grid is there without any data in it. When I reload the page I see the data is back. What can be the reason for this problem? What should I do to solve this problem?

I am implementing the date picker in my system, and the control throws an error in jquery library when run using Ie7 and Ie8 compatibility mode.. I run on Ie10

I know there is a thread which discusses the same issue...
http://www.kendoui.com/forums/kendo-ui-web/date-time-pickers/datepicker-use-ie9-compatibility-mode-ie7-or-ie8-day-not-selected.aspx

 it says.. its fixed in the latest version.. i have the latest one (kendoui.web.2013.2.716)... but i still experience the issue..

I took a screen recording and uploaded on youtube..
http://youtu.be/L_ZgDCtZJkA

I am fine, as long as there is a confirmation from telerik team that, it wud work fine on direct Ie7 and 8 browsers and not the compatibility mode... will it?
