请大伙看看我的 DATAGRID绑定的句子怎么出错了？

[lilac_season]

protected void Page_Load(object sender, EventArgs e)
{
SqlConnection myConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["OnNetBookSellConnectionString"].ConnectionString);
SqlCommand myCommand = new SqlCommand("select * from books");

SqlDataAdapter myDataAdapter = new SqlDataAdapter();
myDataAdapter.SelectCommand = myCommand;


DataSet ds = new DataSet();
myDataAdapter.Fill(ds,"table");

MyDataGrid.DataSource = ds;
MyList.DataBind();

[lilac_season]

出错在最后一句 ： MyDataGrid.DataBind();

[ustbwuyi]

不知道MyList怎么冒出来的

[lee90520]

MyDataGrid.DataSource = ds;
MyList.DataBind();

这里有错，数据源和数据绑定的对象不一样

[卓哥]

MyDataGrid.DataBind();
把这句覆盖原来的MyList.DataBind();

[lilac_season]

mylist写错了，其实是MyDataGrid

MyDataGrid.DataSource = ds;
MyDataGrid.DataBind();

这样还是有错的

[FantasyFreed]

把MyDataGrid换成你DataGrid的ID

[lxtf214]

出的是什么错误啊！

[lilac_season]

MyDataGrid 就是ID啊

[lilac_season]

myDataAdapter.Fill(ds,"table"); 居然这句有错误：Invalid OperationExceptation was unhandled byu user code

[myjieli]

很明显嘛:
SqlCommand myCommand = new SqlCommand("select * from books",myConnection);//少了myConnection!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[lilac_season]

改成：
SqlConnection myConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["OnNetBookSellConnectionString"].ConnectionString);
SqlCommand myCommand = new SqlCommand("select * from books", myConnection);

SqlDataAdapter myDataAdapter = new SqlDataAdapter();

myDataAdapter.SelectCommand = myCommand;


DataSet ds = new DataSet();
myDataAdapter.Fill(ds);

MyDataGrid.DataSource = ds;
MyDataGrid.DataBind();


最后这句出错MyDataGrid.DataBind();

搞定了，原来是<asp:DataGrid........>绑定到错误的列了。多谢大伙！
