先加一个代码

public void SetXtraTabPageVisible(DevExpress.XtraTab.XtraTabControl xtraTabControl, bool iIsVisible, string strTabPageName)        {        //    xtraTabControl1.Visible = true;            foreach (DevExpress.XtraTab.XtraTabPage tabPage in xtraTabControl.TabPages)            {                if (tabPage.Name == strTabPageName)                {                    tabPage.PageVisible = iIsVisible;                }                else                {                    tabPage.PageVisible = !iIsVisible;                }            }        }

这个能实现切换, 结果把另一个页面给彻底隐藏了,当前显示页到了隐藏页的位置, 隐藏的页的页头 也没得了位置,跟我想显示隐藏页的页头不符合.

改成这个方式问题解决

public void SetXtraTabPageVisible(DevExpress.XtraTab.XtraTabControl xtraTabControl, bool iIsVisible, string strTabPageName)        {        //    xtraTabControl1.Visible = true;            foreach (DevExpress.XtraTab.XtraTabPage tabPage in xtraTabControl.TabPages)            {                if (tabPage.Name == strTabPageName)                {                    xtraTabControl.SelectedTabPage = tabPage;//显示该页                      return;                    //  tabPage.PageVisible = iIsVisible;                }                //else                //{                //    tabPage.PageVisible = !iIsVisible;                //}            }        }

 

 双击listview增加相应的tabpage，禁止重复添加：

private void listView_index_MouseDoubleClick(object sender, MouseEventArgs e)  {      if (listView_index.SelectedItems.Count > 0)      {          ListViewItem lvi = listView_index.SelectedItems[0];//得到选中的项          string name = lvi.Text;          //判断是否已创建过          foreach (XtraTabPage page in xtraTabControl.TabPages)          {              if (page.Text == name)              {                  xtraTabControl.SelectedTabPage = page;//显示该页                  return;              }          }          //增加tabpage          XtraTabPage xpage = new XtraTabPage();          xpage.Name = name;          xpage.Text = name;          xpage.Controls.Add(ListView_Tec);//添加要增加的控件          xtraTabControl.TabPages.Add(xpage);          xtraTabControl.SelectedTabPage = xpage;//显示该页      }  }
