我想把一个DataTable中的数据放到一个DataList中，代码如下，DataList确实显示了１００行，但是都没有数据，不知道是为什么，请大家帮忙，另外DataList中的item的Change事件应该如何加啊？
DataTable dt = new DataTable();
DataRow dr; dt.Columns.Add(new DataColumn("编号", typeof(String)));
int index=0;
while(index<100)
{
dr = dt.NewRow();
dr[0]="aaa";
dt.Rows.Add(dr);
index++;
} DataList1.DataSource =dt;
DataList1.DataBind();
DataTable dt = new DataTable();
DataRow dr; dt.Columns.Add(new DataColumn("编号", typeof(String)));
int index=0;
while(index<100)
{
dr = dt.NewRow();
dr[0]="aaa";
dt.Rows.Add(dr);
index++;
} DataList1.DataSource =dt;
DataList1.DataBind();
