Add the closebuttonclick event of xtratabcontrol:

 

Private void xtratabcontrol_closebuttonclick (Object sender, eventargs e) // close the tab method {devexpress. xtratab. viewinfo. closepagebuttoneventargs earg = (devexpress. xtratab. viewinfo. closepagebuttoneventargs) E; string name = earg. page. text; // obtain the text foreach (xtratabpage in xtratabcontrol) of the closed tab. tabpages) // retrieve the text {If (page. TEXT = Name) {xtratabcontrol. tabpages. remove (PAGE); page. dispose (); Return ;}}}
