大家给一个DataTable绑定GridView例子。

现在我把我做的如下
cs文件：
using System;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {


    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        string id = id_TextBox.Text;
        string code = code_TextBox.Text;
        string name = name_TextBox.Text;        DataTable dt = new DataTable();
        dt.Columns.Add("Id", typeof(System.String));
        dt.Columns.Add("Code", typeof(System.String));
        dt.Columns.Add("Name", typeof(System.String));
        dt.Rows.Add(id, code, name);

        }
    }-------------------------------------------------------------------

现在我想把datatable数据在gridview上显示，谢谢了！

this.GridView.DataSource = DataTable;
this.GridView.DataBind();

gridview.datasource=datatable
gridview.databind()

protected void Button1_Click(object sender, EventArgs e)
  {
  string id = id_TextBox.Text;
  string code = code_TextBox.Text;
  string name = name_TextBox.Text;  DataTable dt = new DataTable();
  dt.Columns.Add("Id", typeof(System.String));
  dt.Columns.Add("Code", typeof(System.String));
  dt.Columns.Add("Name", typeof(System.String));
  dt.Rows.Add(id, code, name);
   //...添加几行数据，若没有数据又没做特殊处理，GridView是不现实空表头的
   GridView1.DataSource = dt;
   GridView1.DataBind();
  }

DataTable dt = new DataTable();
dt.Columns.Add("Id", typeof(System.String));
dt.Columns.Add("name", typeof(System.String));
dt.Rows.Add("1","");GridView1.DataSource = dt;
GridView1.DataBind();

public void BindGridView()
  {
  DataTable dt = new DataTable();
  DataColumn dc = new DataColumn("ID", Type.GetType("System.Int32"));
  dt.Columns.Add(dc);
  DataColumn dc1 = new DataColumn("Name", Type.GetType("System.String"));
  dt.Columns.Add(dc1);  DataRow dr = dt.NewRow();
  dr["ID"] = 1;
  dr["Name"] = "srg";
  dt.Rows.Add(dr);
  DataRow dr1 = dt.NewRow();
  dr1["ID"] = 2;
  dr1["Name"] = "cdf";
  dt.Rows.Add(dr1);  GridView1.DataSource = dt;
  GridView1.DataBind();


  }

GridView1.DataSource = datatable.deafultview;
GridView1.DataBind();

this.gridview1`.datasource=dt;
this.gridview1.databind();

GridView 控件可绑定到数据源控件（如 SqlDataSource、ObjectDataSource 等等）,以及实现 System.Collections.IEnumerable 接口的任何数据源（如 System.Data.DataView、System.Collections.ArrayList 或 System.Collections.Hashtable）若要绑定到某个数据源控件，请将 GridView 控件的 DataSourceID 属性设置为该数据源控件的 ID 值。GridView 控件自动绑定到指定的数据源控件若要绑定到某个实现 System.Collections.IEnumerable 接口的数据源，请以编程方式将 GridView 控件的 DataSource 属性设置为该数据源，然后调用 DataBind 方法。如DataTableGridView1.DataSource = datatable.deafultview;
GridView1.DataBind();

con.Open();
            OleDbCommand c = new OleDbCommand(str, con);
            OleDbDataAdapter oda = new OleDbDataAdapter(c);
            DataSet ds = new DataSet();
            oda.Fill(ds, "table1");
            this.GridView1.DataSource = ds.Tables["table1"];
            this.GridView1.DataBind();
            c.Dispose();
            con.Close();

GridView1.DataSource = datatable.deafultview;
GridView1.DataBind();

GridView1.DataSource = dt;
GridView1.DataBind();

DataTable dt=new DataTable();
DataColumn dc=new DataColumn();
dc.ColumnName="标题"; //这里最好用E文
dt.Columns.Add(dc); //把该列加入到表格dt中
DataColumn dc1=new DataColumn();
dc.ColumnName="介绍";
dt.Columns.Add(dc1); //把该列加入到表格dt中 ,其它要添加的列相同方式//如果你有好多数据,就在这里循环建
DataRow row=dt.NewRow();
row["标题"]=txtTit.Text;
row["介绍"]=txtDes.Text;
dt.Rows.Add(row); //行加入至表格中
GridView1.DataSource = dt; //绑定表格到GridView
GridView1.DataBind();

调试易
