Is this in the Q2 2015 beta ?

Is it possible to have a workaround in the meantime?
I have tried solutions proposed here :

... but it is not working at all. I use ASP.NET MVC Razor.

Thank you!

What is the status on this Telerik?
Planned for Q1 2015 ?

C. Symons thanks for workaround, but this should be build in.
Many new developers decide to use other frameworks because Kendo is missing tiny bits that should be there from start

A workaround can be implemented as follows: 1) Add the CSS class "my-expandable" to the grid that should be able to display all rows. The class will be output next to the k-grid class. 2) Include the following CSS classes:

.grid-expander
{
    text-align:center;
    display:block;
    padding-top:0.25em;
    width:100%;
}
.icon {
    position: absolute;
	background: url("images/fontawesomesprite.png") no-repeat;
    overflow: hidden;
    width: 32px;
	height: 32px;
    zoom:0.4;
    -moz-transform:scale(0.4);
    -moz-transform-origin: 0 0;
}
.icon-toggleexpand { background-position: 0px 0px; }

3) Include this function somewhere in your Javascript:

function toggleGridExpansion(pagerDiv) {
    var jqueryThis = $(pagerDiv);
    var pager = jqueryThis.data("kendoPager");
    var ds = pager.dataSource;

    if (!ds.serverPaging) {
        var totalItems = ds.total();
        var originalPageSize = parseInt(jqueryThis.attr("my-original-page-size"));
        if (originalPageSize > 0 && ds.pageSize() != originalPageSize) {
            ds.pageSize(originalPageSize);
        } else {
            jqueryThis.attr("my-original-page-size", ds.pageSize());
            ds.pageSize(totalItems);
        }
    }
}

4) Add the following script to the jQuery startup script for the page:

jQuery("body").find(".my-expandable > .k-grid-pager").each(function () {
	$(this).append("<span class=\"grid-expander\"><span><a href=\"#\" onclick=\"toggleGridExpansion($(this).closest('.k-grid-pager')[0]);return false;\"><span class=\"icon icon-toggleexpand\"></span></a></span></span>");
});

5) Ensure an image is located at images\fontawesomesprite.png as specified in the styles or alter the style so that the grid toggle button becomes visible.

Yes this would be a really great option.

Come on Telerik. This should not be hard but really useful!
