如何在Visual Studio中仅概述一个切换

这是我的代码，我想在我的LoadItemTrackingGrid（）中切换一个大纲，请给我所有大纲的快捷方式。

protected void LoadItemTrackingGrid(object sender, EventArgs e)
{
    LoadItemTrackingGrid();
}

private bool IsEditModeProductGroup()
{
    return (!string.IsNullOrEmpty(lblParentProductId.Text));
}

protected void lnkProductGroupAdd_OnClick(object sender, EventArgs e)
{
    if (ddlProductGroup.SelectedIndex == 0)
        txtProductGroupName.Text = string.Empty;
    else
        txtProductGroupName.Text = ddlProductGroup.SelectedItem.Text;
    popupProductGroup.Show();
    txtProductGroupName.Focus();
}

protected void btnSaveProductGroup_onClick(object sender, EventArgs e)
{
    if (!IsValidProductGroup())
    {
        popupProductGroup.Show();
        return;
    }
    int? ParentProductId = SaveProductGroup();
    LoadProductGroup();
    ddlProductGroup.SelectedValue = ParentProductId.ToString();
    ddlProductGroup_OnSelectedIndexChanged(null, null);
}
