怎么改gridView的 表头？

Question

我在 Dbhelper 里面写了 一 个  gridview 绑定表的方法，在add页面调用
但怎么更改  gridview 显示出来的表头啊 ？在 dehelper.cs页面 public static DataTable Bind()
    {
        SqlConnection conn = DbHelp.creatConn();
        conn.Open();
        SqlDataAdapter sda = new SqlDataAdapter();
        sda.SelectCommand = new SqlCommand("select p_user,p_pass from t_user", conn);
        DataSet ds = new DataSet();
        sda.Fill(ds, "t_user");
        return ds.Tables["t_user"];
    }在add.cs页面调用方法的代码
gridview的前台代码
<asp:GridView ID="GridView1" runat="server" align="center">
    </asp:GridView>后台代码
 public void grid()
    {
        this.GridView1.DataSource = DbHelp.Bind();
        this.GridView1.DataBind();
    }怎么改那个表头啊 

Answer 1

<asp:BoundField DataField="Id" HeaderText="" >GridView1.Columns[0].HeaderText = "Id";
 
GridView1.DataBind();

Answer 2

在GridView1属性的编辑列中
取消GridView1的“自动生成字段”
添加BoundField指定数据DataField为你的数据库字段如name
在GridView1的外观HeaderText填上你要的表头名如名称
其它字段设置相同...

Answer 3

在DataBind()前，手动设置GridView1的HeaderText
public void grid()
    {
        this.GridView1.DataSource = DbHelp.Bind();
        GridView1.Columns[0].HeaderText = "p_user"; 
        GridView1.Columns[1].HeaderText = "p_pass"; 
        this.GridView1.DataBind();
    }

Answer 4

GridView里面有个小三角，你打开，编辑列就可以了

Answer 6

select p_user as '列1',p_pass as '列二' from t_user
这样也行~~~~列不多的话~

Answer 7

不行啊 ，有错
 GridView2.Columns[1].HeaderText = "名字";
索引超出范围。必须为非负值并小于集合大小。
参数名: index
