If a Kendo-Grid is set with .Scrollable(true) the height of the grid get a style with "height:200px;". This seems to be unchangeable without edit the Kendo Source code. But in my opinion this is somehow needed. Of cource it could be changed later with some javascript code but why so intricate? It would be much more efficient to "change" the css i want on the fly.
E.g.
.ScrollableStyle(new { @class = "max-height:300px;" })
