How to change the Delete Button Icon in a row

[CS]

I want to change the icon on the delete button, but I am somehow not able to catch all the activity state icons like :hover and such. How do I replace all of them?

My suggestion would be replacing the style for the icon you wanna change...

Therefore something like 

.k-button .k-i-cancel {
     background-image: url(...) !important;

}

Hello Stefan,

Alternatively you may also use the command configuration options - imageClass and iconClass:

command: [ "edit", { name: "destroy", imageClass: "k-delete", iconClass: "k-icon" }]

In this scenario however your image should be part of a sprite.
If you would like to insert an image by URL please consider aortega's suggestion.
