Hi,

I'm trying to do something very simple.
It is just a menu inside a tree.
But kendo tree gets confused on the onSelect event of the tree. It thinks it is a menu item the e.node!
Could you fix that bug please?

Please open the fiddle and firebug on console tab to see a demo.

Kendo editor tooltips no longer working with Q2

Hello,

A client reported that the tooltips on the custom tools we have in the ediors no longer work after the new Q2 kendo version. So I checked, everything is setup as it has always been via the tooltip property. And I checked the documentation to see if anything changed. Looks the same. Then I went to your demos and saw that you have a custom toolbar and it has a tooltip but its also not showing (latest Google Chrome). I can see in your demo that even though the tooltip is setup, the elemnt has no title.

Is this some bug or am I just doing something wrong?

Cascading dropdowns with many-to-many relationship

Hi all,

I'm using the ASP.NET wrapper, but I figured this question is general enough it would be better posted here.

I'd like to create a cascading dropdown structure for a many-to-many data relationship. An example structure similar to my data:
Course model (id CourseID) can have many Students.
Student model (id StudentID) can have many Courses.
A third table (CourseStudent) links the two IDs, meaning that neither model has an ID reference to the other.

Is there any easy way to do this? Using the "CascadeFrom" method during definition works for one-to-many relationships, but not in this case. Do I need to include a computed property on one of my models in order to have the ID?

Thanks,
Jeff

MVVM with Drag and Drop

I am attempting to use the Kendo UI MVVM framework with the Kendo UI drag and drop mechanic; But I am having a very difficult time finding out how to get the data dropped out of the `draggable` object.

My code is something like this ...

var viewModel = kendo.observable {

Cart : [],

Items : [

{

Id : "item/10",

Name: "CD ROM"

},

{

Id : "item/11",

Name: "DVD ROM"

}

};

So then I have a rough template binding...

<script id="products-template" type="text/x-kendo-template">

<li class="draggable">

<div data-bind="text: Name"></div>

</li>

</script>

Then this gets called up in a list...

<div id="shopping-items-available">

<ul data-template="products-template" data-bind="source: Items">

</ul>

</div>

Then there is a standard "drop target" (taken from the kendo docs)

<div id="droptarget">Start dragging.</div>

with the following CSS

#droptarget {

border: 1px solid #959595;

height: 198px;

width: 300px;

font-size: 36px;

border-radius: 37px;

text-align: center;

line-height: 198px;

color: #a1a1a1;

text-shadow: 0 1px 1px #fff;

margin: 0 0 30px 220px;

cursor: default;

background: #dddddd;

background: -moz-linear-gradient(top, #dddddd 0%, #c1c1c1 100%);

background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#dddddd), color-stop(100%,#c1c1c1));

background: -webkit-linear-gradient(top, #dddddd 0%,#c1c1c1 100%);

background: -o-linear-gradient(top, #dddddd 0%,#c1c1c1 100%);

background: -ms-linear-gradient(top, #dddddd 0%,#c1c1c1 100%);

background: linear-gradient(top, #dddddd 0%,#c1c1c1 100%);

}

Now in the javascript, I turn the `shopping-items-available` div into a `draggable`.

$("body").kendoDraggable({

hint: function (target) {

return $(target).clone().addClass("draggable");

},

filter: ".draggable"

});

and lastly, I initialize the drop target.

$("#droptarget").kendoDropTarget({

drop: droptargetOnDrop

});

but in my code, I cannot seem to get the actual data about the item that was dropped.

function droptargetOnDrop(e) {

console.log(e);

$("#droptarget").text("You did great!");

$(".draggable").removeClass("hollow");

}

So the question is, how can I get the data that should be part of this? Like the name, or the Id?

Kendo UI DataSource / JSON Issue

Sorry for the cross-posting but going crazy on this one.

http://stackoverflow.com/questions/18151901/kendoui-datasource-results-in-invalid-json-primitive

So essentially, when I use a Kendo Data Source and send anything in the data: field as part of the transport/read command this is what I see come across in fiddler in the json request.

0=%7B&1='&2=s&3=U&4=s&5=e&6=r&7=n&8=a&9=m&10=e&11='&12=%3A&13='&14=a&15=d&16=m&17=i&18=n&19=%40&20=m&21=a&22=i&23=l&24=.&25=c&26=o&27=m&28='&29=%2C&30='&31=s&32=P&33=a&34=s&35=s&36=w&37=o&38=r&39=d&40='&41=%3A&42='&43=1&44=3&45=1&46=2&47=3&48='&49=%2C&50='&51=s&52=U&53=s&54=e&55=r&56=I&57=D&58='&59=%3A&60='&61=1&62=5&63=3&64=9&65='&66=%2C&67='&68=s&69=C&70=l&71=u&72=b&73=I&74=D&75='&76=%3A&77='&78=1&79='&80=%7D

If I don't use the Kendo Data Source and just a common ajax request I don't see these problems at all. Just curious if anyone has seen this before. I must be doing something stupid.

Thanks,

Richard

ListView Filtering - loading icon always showing

It's seems that after the latest update (v2013.1.716), the loading icon from ListView is showing all the time after doing a search. Was this the intended behavior?
The example here http://demos.kendoui.com/mobile/listview/filtering.html#/ behaves the same way. It's kinda misleading...makes you think there's still something out there.
This does not happen in v2013.1.703, or earlier as I recall.

endlessScrolling bug JS Bin example (.719)

http://jsbin.com/owilaf/17#/
http://jsbin.com/owilaf/17/edit

Using a simple template like <a>${ProductName}</a> causes the ListView to be buggier.
Using a more complex one like
<div class="product">
<img src="../../content/web/foods/#=ProductID#.jpg" alt="#=ProductName# image" class="pullImage"/>
<h3>#:ProductName#</h3>
<p>#:kendo.toString(UnitPrice, "c")#</p>
</div>
paradoxically will make the ListView to behave a bit better.
ScrollView is messed up, ListView the same... I think I'll go back to .703 or .514 even though I need the ListView virtualization. (the GetByUid undefined bug which is fixed only in .716)

endless scroll stops after adding an item to the data-source

I have a listview with a data-source that's setup to get 10 items at a time and perform endless scroll. This list is basically a chat wall, so when it's first loaded I'll get the most recent 10 posts and if user scrolls down I'll get older posts, etc. While the user is actively in the list, if a new post arrives I'm simply adding the post to the data source which is then appending the new post to the listview, etc. However, once I add an item to the data source the endless scroll no longer works when the user scrolls down.

After adding the item to the data source, do I need to set anything else on the data source to keep endless scroll alive. I'm originally setting the schema.total to zero since the user will basically never reach the end of the data items anyway.

Bug in listview when adding option "endlessScroll: true"

Hi,
after I have updated my mobile app to kendo Q2 I've had some weird behavior with the "kendoMobileListView" .
Once the list has been loaded the loading image just keeps there spinning, and the data has been shown already. I removed this property and it worked fine and once I've add it again the list made the same issue.
