Automatic init event on all Views

Hi guys

Is there a way to attach the same init method (beforeShow and show too) to all Views, without specifying on html? Or maybe a way to bind to an event that gets triggered from all Views?

I think a good way to solve this would be the possibility to specify the View init method through the Layout. I have many Views with the same Layout, and all of them use the same init and show method. If we could put that in the Layout, the markup would become simpler and more maintainable.

Thanks!

resize add, edit and delete icons

I am amending the CSS files to tailor buttons and screens to suit our company layout and it will be necessary to resize the icons depending on the amount of data on the screen. I have made some modifications which reduce the size of the text box and text, but I cannot successfully get the image icon to shrink. I have managed to remove the icon to just display text, but ideally I would like the button to either display the icon and text if the the button is big enough but just text if the button is small. At the moment when text only is displayed the text is off centre. My code for the button and the icon is as follows:
.k-button.k-button.k-button-icontext {
    /*background-position: top;*/
    font-style: normal;
    font-family: Calibri;
    font-weight: normal;
    font-size: small;
    border-image-outset: 0px;
    /*height: 16px;*/ /*font-size-adjust: inherit;*/
    vertical-align: top;
    text-align: center;
    white-space: normal;
    /*overflow: auto;*/
    margin: 0px,0px,0px,0px;
    }

.k-icon {
    /*fit:slice;*/
    /*background-image:none;*/
    display: inline-block;
    width:auto;
    height:auto;
    background-size:contain;
}
I also have another button which does not have an icon which needs to be the same size as these buttons which is why I need generic code to suit the row height.
As you can see I was experimenting with some other options - with the current settings the icon is not being displayed although I think there is enough room. Any suggestions of amending the code gratefully received.

Infinite Scrolling

I would love to see infinite scrolling make it into the roadmap at some point. This is essential UI, especially on mobile and the plugins that are out there haven't really nailed it down yet.

Just a thought...

Array of DataSource versus HierarchicalDataSource

Assuming your data only has two levels of depth, in which case would you favor an array of (objects containing a) DataSource versus a HierarchicalDataSource and vice versa?

In such a case, we are tempted to use option 1 because the DataSource is much better documented and easy to grasp than the HierarchicalDataSource but the HierachicalDataSource might have hidden benefits worth the learning curve.

triggering combo box events programmatically

I have a combo box set up to cascade to another combo box. This works. I have mapped both a change event and a select event in the "parent" - - both of which also work. I am planning to observer the state of the "parent" knockout via the knockout-kendo plugin. I expect this to work.

BUT - I need to be able to trigger the cascade programmatically, as well. That is, I need to programmatically change the selected index of the "parent". To test this in advance of mapping it in knockout, I have a test button that successfully changes the selected item in the "parent". So, this works.

Here is problem: neither the change event nor a select event are triggered in response to the following (which is in the test button click handler):

var cbx = $("select").data("kendoComboBox")

cbx.select(2);

That is, the combo box changes state but kendo is not triggering either of the events.

I have tried this in various fiddles (modifying a similar situation) and it does not work there either.

This is quite important to us, so please let me know if this is not supported.

Thanks
