C#—Dev XtraTabControl动态增加Tab和关闭选项卡方法

 

记录一下以免以后忘了

添加using DevExpress.XtraTab;

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
    }
}

 

1.点击关闭按钮关闭

 

若要tabpage显示关闭按钮，把xtraTabControl的ClosePageButtonShowMode属性设为InAllTabPageHeaders；若想要首页不显示关闭按钮：

 

xtraTab_index.ShowCloseButton = DevExpress.Utils.DefaultBoolean.False;//首页不显示关闭按钮

 

添加xtraTabControl的CloseButtonClick事件：

 

private void xtraTabControl_CloseButtonClick(object sender, EventArgs e)//关闭选项卡方法
{
    DevExpress.XtraTab.ViewInfo.ClosePageButtonEventArgs EArg = (DevExpress.XtraTab.ViewInfo.ClosePageButtonEventArgs)e;
    string name = EArg.Page.Text;//得到关闭的选项卡的text
    foreach (XtraTabPage page in xtraTabControl.TabPages)//遍历得到和关闭的选项卡一样的Text
    {
        if (page.Text == name)
        {
            xtraTabControl.TabPages.Remove(page);
            page.Dispose();
            return;
        }
    }
}

 

2.双击标签关闭

得到你现在鼠标所在的Page

 

XtraTabPage CurrentPage = new XtraTabPage();

private void xtraTabControl_HotTrackedPageChanged(object sender, DevExpress.XtraTab.TabPageChangedEventArgs e)
{
    try
    {
        CurrentPage = e.Page;
    }
    catch (System.Exception ex)
    {
        CurrentPage = null;
    }
}

 

private void xtraTabControl_MouseDoubleClick(object sender, MouseEventArgs e)
{
    if (CurrentPage != null)
    {
        xtraTabControl.TabPages.Remove(CurrentPage);
        CurrentPage.Dispose();
    }
}
