I am afraid, presently we do not have any such feature. One possible option could be to use the ComboBoxBarItem which serves the function of a TextBoxBarItem (with autoappend functionality). Another option would be to use a detached bar (XPToolBar) and drop a TextBox control into it. We could consider a TextBoxBarItem type of control as a feature request for a future release of Essential Suite. Thanks for considering Syncfusion products.
