I have a functioning TreeView using and Ajax datasource that displays six root nodes, some of which have children.  I want to automatically find a child node by its id and then select the child and expand it's parent node(s) in order to be visible.  The problem I have is that the TreeView only loads the root nodes.  Querying both the tree and datasource result in the child not being found, but I can find and select one of the six root nodes.  I have tried setting LoadOnDemand(false), but it doesn't load all the child nodes.

I have not been able to wrap my brain about how to generate a full hierarchical dataset in my MVC controller to return as JSON that would have all the child nodes based on the examples I have seen.  Am I missing a method/configuration setting to load all children in the tree automatically?    I've been Googling and looking at lots of stuff, but maybe I'm just being dense.  

Any pointers are appreciated!

I finally found out the root of the problem.  I found it in this post:

http://www.kendoui.com/forums/mvc/treeview/treeview-ajax-without-load-on-demand.aspx

The LoadOnDemand(false) does not work when using the MVC Wrapper and a HierarchicalDataSource.  Once I converted to pure JavaScript initialization, everything started to work once I converted my data to a hierarchical structure.  For those of you looking for a good library to convert flat tables into a hierarchical structure, take a look at this set of classes.  They worked great for me.  The only drawback is that it does not work with null parentIds.

I also made use of this Linq example to convert the model:

Finally to find, select, and expand the necessary nodes in the tree, I leveraged this example:

Hopefully others will find these references useful. 

I've spent a lot of time trying to get items that are added to a ListView or "source" bound element (i.e. <div data-bind="source: myData"></div>) to fade in using FX Fade (http://docs.kendoui.com/api/framework/fx/fade) instead of just appearing abruptly.  Unfortunately, I have been unsuccessful.  Can you explain how to do it in *both* cases (i.e. when using a ListView and when using source binding)?

Here is as far as I got when trying it with a ListView:

Your help would be greatly appreciated.  Thanks.

Morning All,

Are there any plans to release a light box or image gallery control?  

I have seen your AeroViewer Demo , which is close to my clients requirement but as yet no source to see which controls you have used to create it.

Are controls for multimedia on your RoadMap?

Cheers

How can I turn on (or create) a subtle hover highlight for rows when my grid is row-selectable?  

This should be a built-in feature since such an effect should look good within the chosen theme.  

If it's not, can you suggest some CSS and what class to apply it to that would use theme-friendly hover highlighting?

Hi,

I'm trying to display a single data object which is loaded through a remote datasource.

My ideal component would be either

a) A listview which stretches to the entire screen and doesnt scroll
or
b) A view which has the data source loading functionality of a list view and passes that into a view

Do you have any recommendations on how to proceed? Are there other alternatives which I haven't considered?

Thank you!
Matt

Hello,

I have a custom mobile site that is using a hand-built mobile framework, but at the end of last year, we imported a kendo ScrollView into the site in order to have and improved image carousel.

This worked flawlessly, we simply called:
$(SELECTOR_HERE).kendoMobileScrollView();

This week, we attempted to update the site to the Q1 release (v2013.1.319 ) of the Kendo Framework, and found that this line has started throwing an error and no longer creates a carousel.

 After importing the non-compressed version of kendo mobile, I was able to track down the following:
MobileWidget = Widget.extend({
        ...
        ...
        container: function() {
            var element = this.element.closest(kendo.roleSelector("view layout modalview"));
            return kendo.widgetInstance(element, kendo.mobile.ui) || ContainerNullObject;
        }

After running the debugger, I can see that element is undefined, so I am assuming that kendo is now assuming that I am forcing the whole site to be a mobile app... which would be a ton of work to implement on this legacy site.

Has kendo officially stopped supporting individual initialization of the mobile components unless you are running the whole page as an app? (this would be very disappointing and greatly reduce the usefulness of the product for my company)

If not, can anyone tell me if the syntax changed or something in Q1?

Thanks!

Hi:

I have a Company entity with a collection of child Employee entities.  The controller is defined like this:

The company entities appear in the first level of the treeview correctly.  Where there are employees, the graphic on the left appears, but when I try to click on it to show them, it disappears.  As you can see, I am renaming the columns in the employee records to match the same names so they should bind correctly, shouldn't they?  I've looked at the remote data example, but the demos won't work on my machine (I've got another post asking about that), so I can't see what the json string should look like.

My Razor MVC cshtml looks like this:
The employee entities exist correctly when I view them from the controller code.  Can you tell me what I am missing?

Thanks,

Terry

hi expert,

I am new to Kendo component. In our project, we do not use the MVVM model because we adapt an existing application. We do a kind of face-lift with Kendo control. We have no problem to provide data to Combobox, calendar and some smaller control. But with the grid we hit a wall! ;-)


All object are quite complex with setter and getter and got several link to other object. I am not the "object part" programmer and I can't talk much on that. The point is that when I do:



The JS start a big big non stop loop. If I break the process and check in the stack windows of me firebug, I can see that KendoGrid try to do many many "Wrap" again the object. I think Kendo read the custom object and try to wrap it to Observable or something like that. Than Kenfo follow link to other objet and loop indefenitly.


Do I have a way to block that? Can I define manually with object to link. Example: Obj1.Title to column 1 and obj1.Name to column 2 ?


Any suggestion?

I have an HTML5 <progress> element where I want both the value and the max driven by the VM.

I have tried this on a couple browsers, and it seems that attribute values for MAX and VALUE are fetched at init, but are not later updated. Is this something that can be driven dynamically? My fallback will have to be JQuery.

I have a page that loads an ajax request into a mobilelistview. Everything works fine except the loadmore button appears no matter if there is more data or not. Here's my code:

I have confirmed total and pageSize return the correct information but even if total is 0 the load more button appears. Is this a kendo bug or have I done something screwy with the code?
