TabContainer的OnActivetabChanged用法

在前台TabContainer添加事件
OnActivetabChanged="TabContainer1_ActiveTabChanged"


后台代码在OnActivetabChanged事件中执行GridView的绑定事件

        protected void TabContainer1_ActiveTabChanged(object sender, EventArgs e)
        {
            DataSet ds = new DataSet();
            GridView1.DataSource = GetData(ds).Tables["Table_VIP"];
            GridView1.DataBind();
        }


 

注意,需要在Page_Load方法里调用该事件,否则在切换Tab的时候是没有反应的,因为它不会postback

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                this.TabContainer1_ActiveTabChanged(sender, e);
            }
        }
