Text; Determine if you have created foreach (Xtratabpage page in xtratabcontrol.tabpages) { if (page. Text = = name) { Xtratabcontrol.selectedtabpage = page;//Show this page Return } } Increase TabPage Xtratabpage xpage = new Xtratabpage (); Xpage. name = name; Xpage. Text = name; Xpage. Controls.Add (Listview_tec)//Add the control to be added XTRATABCONTROL.TABPAGES.ADD (Xpage); Xtratabcontrol.selectedtabpage = xpage;//Show this page } }

To TabPage display the Close button, set the Xtratabcontrol Closepagebuttonshowmode property to Inalltabpageheaders; If you want the first page to not show the Close button:
