Hello,

Wenn someone adds or modifies a task, the server checks if this is possible or not.
​At certain dates or times a task cannot created (holidays, already another task,....).
​The server/database  checks if this is possbile or not. if not I return a errormessage within a JSON.
​How do I show this errormessage to the user in de scheduler-popup window ?
 

I have a dropdown list that is populated via ajax call.
Depending on what the user is allowed to do the dropdownlist might only have 1 item in it.
I need to add a empty option first, then append the ajax results.

I do this all the time in asp.net webform applications, how does one configure a kendoui dropdownlist to display the empty row but not allow it to be selectable?

Is it possible to have the drawer open to a percentage of the page? Trying to make a responsive page for mobile/tablet and I want on mobile to open to 90%, but on tablet to only open to 50%.

I have implemented this with the javascript:
<div class="drawer" id="myDrawer">
</div>

 $("#myDrawer").kendoMobileDrawer({
            container: "#content-container",
            swipeToOpen: false
            }
        });


Thanks.

I've noticed in working with KendoUI ComboBox widgets that the standard "labeled control" behavior within HTML breaks with these widgets.

So in the following (taken from combobox demo page), when clicking on the "Categories" label, the ComboBox widget does not automatically get focus.

<label for="categories">Categories:</label><input id="categories" style="width: 270px" />

Seems to work fine with other widgets, like the DatePicker.

Thank you.

I have 2 questions regarding the scheduler's popup
1) how to preselect a value in the combobox ?
2) how to remove the 'none'-item in the combobox ?

Dear Telerik`s developers;
I am wondering too whether we can use Google Map api or not - in Telerik map?
I have noticed that we can use Bing. Like that,   would using Google  be  possible?

Hi,
In my application I don't need to use all the fancy features of DataSource. So I thought to use an array of kendo.data.Model objects inside the ViewModel.

There is a property called "dirty" and another called "isNew()".

If I want to get all new objects added on client, then I can filter based on isNew = true. To get all those items that need to be updated on server, then I look at "dirty = true".

Is the above correct? Is there another way (could be better) to get list of items to be deleted, updated, created on server?

One more thing, I noticed that if I update a newly added item on client-side, its dirty becomes true and isNew is false. Is that the normal behavior?

Finally, is there a way to use DataSource as a local database on client side to track updated, created, and deleted records, however, having it based on "data" property, i.e. without any remote transport stuff? Then, I could use DataSource as a local storage to track all changes, then I can filter out rows to be deleted, created and updated on server. 

Thanks

The following test works (using http://mochajs.org + http://chaijs.com):


The following test fails:


How can I at least test that viewModel.item.attributes is an observable? Otherwise what instance of is it?

We are trying to port a Telerik MVC tree to a Kendo UI treeview. Most of the things works great using the hierarchical datasource, but there is one thing I'm missing in the new Kendo UI controls; the loadondemand option on the node itself.

In the old MVC controls I could indicate on each node if it had children AND if it needed a load on demand. I needed this because my tree is based on some filters and settings, so the layering can differ each time. Some of the database queries I can do more easily by retrieving two or three levels at the same time.

So for example I can load the following construct:

A 
 - B
 - - C

With the MVC Control for both A, B and C I could indicate that they have children, but only C need to invoke another request, so it had the loadondemand value on true.

With the Kendo UI treeview, I'm unable to specify per node the loadondemand option. So I can return level A but then I need to indicate they have children (otherwise the expand icon is not shown) and the child items are not rendered. If you click the expand arrow, it will however not use the items collections, but will invoke a new request to load the next level. Not needed because that level is already loaded. In the MVC controls I could indicate this, but in Kendo UI there is no option for this. I tried to set the children property in the schema, but I'm unable to set it as a function (for example; if item has items, use it, otherwise use the datasource itself to load new level).

So is it somehow possible to use both a node with child items and a node that needs on demand loading?

Hi Telerik Team,

Good day!

I would like to ask for your help with regards to text label of "Select" button is mis-aligned after I selected the file in Kendo Upload.

I already adjusted the height of my div in html, still the text label is mis-aligning and not in the center or middle.

I'm using async upload and I use IE-11 browser (Internet Explorer 11)

Thank you in advance for your immediate Help and Solution.
