c#dev tabcontrol 切換頁面時注意的問題

先加一個代碼

  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;
                }
            }
        }

這個能實現切換, 結果把另一個頁面給徹底隱藏了,當前顯示頁到了隱藏頁的位置, 隱藏的頁的頁頭 也沒得了位置,跟我想顯示隱藏頁的頁頭不符合.

改成這個方式問題解決

 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;//顯示該頁  
                    return;
                    //  tabPage.PageVisible = iIsVisible;
                }
                //else
                //{
                //    tabPage.PageVisible = !iIsVisible;
                //}
            }
        }

 

 雙擊listview增加相應的tabpage，禁止重復添加：

private void listView_index_MouseDoubleClick(object sender, MouseEventArgs e)  
{  
    if (listView_index.SelectedItems.Count > 0)  
    {  
        ListViewItem lvi = listView_index.SelectedItems[0];//得到選中的項  
        string name = lvi.Text;  
        //判斷是否已創建過  
        foreach (XtraTabPage page in xtraTabControl.TabPages)  
        {  
            if (page.Text == name)  
            {  
                xtraTabControl.SelectedTabPage = page;//顯示該頁  
                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;//顯示該頁  
    }  
}
