数据网格视图未加载 [英] Data grid view not loading

问题描述

我有一个gridview，我必须在其中加载用户的当前书籍详细信息.用户ID作为会话传递，并基于该会话显示网格视图

I have a gridview where i have to load the current book details of a user. The userid is passed as a session and based on that session the grid view is displayed

protected void Page_Load(object sender, EventArgs e)
    {
      
      
        if (Session["userid"] != null)
        {
            string key = Session["userid"].ToString();
            SqlDataSource1.SelectCommand = "SELECT fname,lastname,number,userid from users where userid= '" + key + "'";
            YourGridView.DataSource= SqlDataSource1;
            YourGridView.DataBind();
        }

    }

但是girdview只是显示为空白.我已经检查了会话是否为空白.不是.为什么gridview为空白?

But the girdview just shows blank .I have checked whether the session is blank or not .It isin''t. Why is the gridview blank?

推荐答案

            SqlDataSource1.SelectCommand = "SELECT fname,lastname,number,userid from users where userid= '" + key + "'";
            YourGridView.DataSource= SqlDataSource1;
