We simply have an Override in our own CSS file that does this. Looks like this:
.aw-form .form-inline .form-group, .form-inline .k-grid {
margin-bottom: .2em !important;
}
Obviously you can change the .2em to any value you like. We spent quite some time to build a CSS file that overrides a ton of things like that. Extra lines, Extra margins etc. You need to really decide what you want the Final result to look like by playing in the inspector and then making those global Kendo/Aware Overrides in your own CSS file. Worth it though.
