回答1:

Is it devexpress' grid view, isn't it? I don't know if this solution will suit your needs, but you can insert normal button control near grid and put code from answer on this site, inside click action.

EDIT: Found answer for your question - unfortunately it's not possible to add custom button to auto filter row

回答2:

(From the top of my head, I assume this is for the WinForms controls)

You'll need to have two RepositoryItems, one without the clear button, and one with the button (you can add buttons via the RepositioryItem's Buttons property).

You'll assign the RepositoryItem without the additional button to the relevant column.

Then you'll need to handle the GridView's CustomRowCellEditEventHandler. Check if the event's e.RowHandle equal GridControl.AutoFilterRow, and if so, assign e.RepositoryItem to the RepositoryItem with the clear button.

Then handle the clear button RepositoryItem's ButtonClicked event.
