I suppose you are using Ajax. In this case you should do the following:
1. Submit the information, which is outside the Grid.
2. Rebind the Grid in the success
event of the Ajax request.
This algorithm will ensure that the Grid is refreshed with the new data, otherwise there is no guarantee about that.
If needed, you can display an Ajax loader over the Grid as soon as you perform the request from point (1).
Since the Grid will display the same animated loader automatically over its data area, you can use the following approach to avoid seeing two different loading indicators.
"#YourGridID > .k-grid-content"
