GridView控件RowDataBound事件的一个实例

实现点击两个按钮，跳转到同一个界面，HyperLink显示不同的东西，主要代码段如下

前台代码：

           <asp:TemplateField HeaderText="操作">
                <ItemTemplate>
                    <asp:HyperLink ID="HlOperate" runat="server"></asp:HyperLink>
                </ItemTemplate>
                <HeaderStyle HorizontalAlign="Center" />
            </asp:TemplateField>

后台代码：flag为两个按钮传来的数据

    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {

            HyperLink hlOperate = (HyperLink)e.Row.FindControl("HlOperate");
            String flag = Request.Params["flag"];
            if (flag == "")
            {
                hlOperate.Text = "A";
                hlOperate.NavigateUrl = "~/GetFyqd.aspx?HEALTH_EVN_ID=" + DataBinder.Eval(e.Row.DataItem, "HEALTH_EVN_ID") + "&VISIT_ORGANIZATION_CODE=" + DataBinder.Eval(e.Row.DataItem, "VISIT_ORGANIZATION_CODE");
            }
            else if (flag == "")
            {
                hlOperate.Text = "B";
                hlOperate.NavigateUrl = "";
            }
        }

    }
