c#dev tabcontrol 切换页面时注意的问题

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 > )
    {
        ListViewItem lvi = listView_index.SelectedItems[];//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
    }
}
