绑定数据列表后，只需调用下面的给定函数即可.

Hi,
After binding your datalist just you need to call the given function below.

private void fnChangeLinkStyle(){
    foreach (DataListItem dli in DataList1.Items)
    {
        if (dli.ItemType == ListItemType.Item || dli.ItemType == ListItemType.AlternatingItem)
        {
            HyperLink btn = dli.FindControl("HyperLink1") as HyperLink;
            if(btn.NavigateUrl=""){
                //Change the hyperlink style here.
            }
        }
    }

}

祝一切顺利.
