Kendo grid doesn't have in-built functionality to prevent row selection based on some condition.
One way is to remove css class "k-state-selected".
But i think there should be something like "changing" event which will be called before "change" event.
In that event developer write code and can cancel "change" event.
Or 
Boolean property something like "enabled" at row level (or cell level for cell selection) .

The row reordering functionality does not work correctly when the draggable column has a small width.

Reproduction of the problem

https://dojo.telerik.com/@user192/ipOyacoH

Open the Dojo and try to reorder a row. The icon inside the hint will keep changing and in some cases you won't be able to drop the row to the expected position.

If you move the hint a bit to the right(towards the next column) this behavior disappears.

Current behavior

The reorder hint shimmers and in some cases does not allow for reordering. This occurs when the column width is small(30px in the example).

Expected/desired behavior

Reorder should work as expected, regardless of the column width.

When using Grid custom editor, the Kendo Editable adds data-binding for the value for both the hidden and the visible inputs of the ComboBox. This results in a field named [propertyName]_input to appear in the item model after it has been edited.

The way this happens is a bit inconsistent and depends on setup, but in the linked dojo, using tab after editing causes this to happen, but in our applications pressing enter  and sometimes even clicking off the editor causes this issue. 

Reproduction of the problem

• Go to the following Dojo sample; https://dojo.telerik.com/OfiCoyog
• Edit the category column and wait for the combobox.
• Type free text, without selecting a value;
• Press tab - the value won't be updated. Also, if you look at the Item, it will have a Category_input field, that has been added, while editing;
