ASP.NET GridView超链接问题

Question

我在做项目时,在GridView建一个超链接列,开始超链接是死的,上面绑定了好多参数,         HyperLinkColumn ruleNameColumn = new HyperLinkColumn();
            ruleNameColumn.HeaderText = "RuleID";
            ruleNameColumn.DataTextField = "RuleID";
            ruleNameColumn.DataNavigateUrlField = "RuleID";
            ruleNameColumn.HeaderStyle.Width = 100;
            ruleNameColumn.DataNavigateUrlFormatString = "ByRun.aspx?UpPage=ByRule&RuleID={0}&ModuleID=" + module + "&EQID=" + EQID + "&SDT=" + startTime + "&EDT=" + endTime;
            DataGrid2.Columns.Add(ruleNameColumn);
问题在于内容中添加行数据后,需要根据某个值来决定跳到哪个页面,也就是需要添加数据后根据该行中某个值来更改列中的DataNavigateUrlFormatString,我没有接触过这样的问题，我分不多，会尽力给.

Gridview 添加  RowDataBound 事件   <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnRowDataBound="GridView1_RowDataBound">
            <Columns>
                <asp:BoundField DataField="ID" HeaderText="编号" />
                <asp:TemplateField HeaderText="查看">
                    <ItemTemplate>
                        <asp:HyperLink ID="HyperLink1" runat="server"></asp:HyperLink>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

                }
                else
                {
                    link.NavigateUrl = "B.aspx";
                }
            }
        }
    }
}

在 RowDataBound 中写代码进行处理。FindControl 效率不高，可以自己写查找函数实现此功能或者用下标访问
