如何将GRIDVIEW选定行的内容显示在ＴＥＸＴＢＯＸ

Question

如何将GRIDVIEW选定行的内容显示在ＴＥＸＴＢＯＸ，要实现以下功能
页面左侧是一个GRIDVIEW，只显示了标题字段，我想点击其中一行后，在右边的４个ＴＥＸＴＢＯＸ里显示数据表中的其他内容，标题字段已经做了链接，谢谢！

Answer 1

首先设置DataKeyNames属性：
<asp:GridView ID="GridView1" runat="server" DataKeyNames="field1,field2,field3,field4">然后:protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
   this.TextBox1.Text = this.GridView1.SelectedDataKey["field1"].ToString();
   this.TextBox2.Text = this.GridView1.SelectedDataKey["field2"].ToString(); 
   this.TextBox3.Text = this.GridView1.SelectedDataKey["field3"].ToString(); 
   this.TextBox4.Text = this.GridView1.SelectedDataKey["field4"].ToString();  
}

首先设置DataKeyNames属性：
<asp:GridView ID="GridView1" runat="server" DataKeyNames="field1,field2,field3,field4">标题列用<asp:ButtonField CommandName="Select"  DataTextField="标题字段" />然后:protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
   this.TextBox1.Text = this.GridView1.SelectedDataKey["field1"].ToString();
   this.TextBox2.Text = this.GridView1.SelectedDataKey["field2"].ToString(); 
   this.TextBox3.Text = this.GridView1.SelectedDataKey["field3"].ToString(); 
   this.TextBox4.Text = this.GridView1.SelectedDataKey["field4"].ToString();  
}

还是没反映啊，麻烦帮我看一下，刚学习，很困难谢谢了
public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    { 
       
            string conn = ConfigurationSettings.AppSettings["strConn"].ToString();            SqlConnection con = new SqlConnection(conn);
            con.Open();
            SqlDataAdapter myCommand = new SqlDataAdapter("newsList", con);
            DataSet myDataSet = new DataSet();
            //填充DataSet     
            myCommand.Fill(myDataSet);
            //关闭链接   
            GridView1.DataSource = myDataSet;
            //绑定     
            GridView1.DataBind();
      
   
       
    }
    protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {
        
        this.TextBox1.Text = this.GridView1.SelectedDataKey["biaoti"].ToString();
        this.TextBox2.Text = this.GridView1.SelectedDataKey["fabuzhe"].ToString();
        this.TextBox3.Text = this.GridView1.SelectedDataKey["shijian"].ToString();
        this.TextBox4.Text = this.GridView1.SelectedDataKey["neirong"].ToString();  
    }
}

protected void Page_Load(object sender, EventArgs e)
    { 
       if(!IsPostBack)
        {
            string conn = ConfigurationSettings.AppSettings["strConn"].ToString();            SqlConnection con = new SqlConnection(conn);
            con.Open();
            SqlDataAdapter myCommand = new SqlDataAdapter("newsList", con);
            DataSet myDataSet = new DataSet();
            //填充DataSet     
            myCommand.Fill(myDataSet);
            //关闭链接   
            GridView1.DataSource = myDataSet;
            //绑定     
            GridView1.DataBind();
      
       }
       
    }
    protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {
        
        this.TextBox1.Text = this.GridView1.SelectedDataKey["biaoti"].ToString();
        this.TextBox2.Text = this.GridView1.SelectedDataKey["fabuzhe"].ToString();
        this.TextBox3.Text = this.GridView1.SelectedDataKey["shijian"].ToString();
        this.TextBox4.Text = this.GridView1.SelectedDataKey["neirong"].ToString();  
    }
}

别忘了注册事件处理程序：
 <asp:GridView ID="GridView1" runat="server" DataKeyNames="id,name,sex,deptid" OnSelectedIndexChanged="GridView1_SelectedIndexChanged"  >标题列用<asp:ButtonField CommandName="Select"  DataTextField="标题字段" />protected void Page_Load(object sender, EventArgs e)
    { 
       if(!IsPostBack)
        {
            //查询数据，绑定GridView
           //因为每次回传都会先执行Page_Load，然后才是其他事件处理程序，如果每次回传都重新绑定，那就没效果了
       }
