Ajax tabContainer使用GridView内部面板，tabContainer外部有一个按钮

Question

我正在使用具有5个tapPanel的Ajax选项卡容器创建管理面板，并且在每个tapPanel中，我都有一个标准工具面板。 在每个面板中，我都有GridView来显示添加的数据。 最后，我在Ajax tabContainer外部有一个“添加”按钮。 如果允许，我将发布设计。 问题是，我不知道tabContainer的编码。 我创建了10个方法，因此可以在单击“添加”按钮时调用它。

这是我的代码不起作用。

namespace Admin_Panel
{
    public partial class add : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Session["Page"] = "ADD";           
        }

        protected void btnAddCat_Click(object sender, EventArgs e)
        {
            AjaxControlToolkit.TabContainer container = (AjaxControlToolkit.TabContainer)TabConAddInfo;
            AjaxControlToolkit.TabPanel tcTabPanel = new AjaxControlToolkit.TabPanel();

            if (tcTabPanel.HeaderText == "Splash")
            {
                addSplash();
                lblMsgAdd.Text = "Added successfully";
            }
            else if (tcTabPanel.HeaderText == "Main Category")
            {
                addMainCat();
                lblMsgAdd.Text = "Added successfully";
            }

请使用以下代码：

        AjaxControlToolkit.TabContainer container = (AjaxControlToolkit.TabContainer)TabConAddInfo;
        int index = container.ActiveTabIndex;

        if (index == 0)
        {
            addSplash();
            lblMsgAdd.Text = "Added successfully";
        }
        else if (index == 1)
        {
            addMainCat();
            lblMsgAdd.Text = "Added successfully";
        }
        else if (index == 2)
        {
            addSubCat();
            lblMsgAdd.Text = "Added successfully";
        }
        else if (index == 3)
        {
            addBusinessContact();
            lblMsgAdd.Text = "Added successfully";
        }
        else if (index == 4)
        {
            addPersonContact();
            lblMsgAdd.Text = "Added successfully";
        }
