关于datagril超级链接问题

我在aspx.cx中有datagril的如下代码。但不知怎么将第一列(fchrTopicCaption)做成超级链接。
在aspx中加入如下,又报在数据源中找不到fchrTopicCaption。请诸位帮忙解决 先谢谢 了
++++++++++++++++++++++++++++++++++++++++++++
<Columns>
<asp:HyperLinkColumn DataNavigateUrlField="fchrFunctionID" DataTextField="fchrTopicCaption" HeaderText="标题"
NavigateUrl="ForumList.aspx?fchrFunctionID=(0)"></asp:HyperLinkColumn>
</Columns>
+++++++++++++++++++++++++++++++++++++++++++
aspx 代码:
private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
if(!Page.IsPostBack)
{
DataGridDataBind();
}
}
//绑定数据
private void DataGridDataBind()
{
string id=Request.QueryString["fchrFunctionID"];//传递来的ID
DataSet ds = GetCustomersData(id);

recordCount = ds.Tables[0].Rows.Count;
//获取当前的页数
pageCount = (int)Math.Ceiling( recordCount * 1.0 / PageSize);
//避免纪录从有到无时,并且已经进行过反页的情况下CurrentPageIndex > PageCount出错
if(recordCount ==0)
{
this.dgrTopicList.CurrentPageIndex = 0;
}
else if(this.dgrTopicList.CurrentPageIndex >= pageCount)
{
this.dgrTopicList.CurrentPageIndex = pageCount - 1;
}
DataView dv = ds.Tables[0].DefaultView;
this.dgrTopicList.DataSource = dv;
this.dgrTopicList.DataBind();
NavigationStateChange();
}
//数据绑定
