推荐答案

希望你的pageload中的bind方法遇到问题请看下面的解决方案

Hope so your bind method in pageload is getting problem see the below solution

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

错了。



应该是：

is wrong.

It should be:

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