连接HyperLinkField单击到服务器端方法(c#)

Question

我有一个HyperLinkField,我用数据表中的url填充,数据表中的字段称为EncodedAbsUrl.

但是,我想将此链接连接到代码隐藏方法

我现在应该做什么

var encodedAbsUrl = new string[] { "EncodedAbsUrl" };
var hf = new HyperLinkField
{
    HeaderText = "Link",
    DataTextField = "ServerUrl",
    DataNavigateUrlFields = encodedAbsUrl,
    DataNavigateUrlFormatString = "{0}",
    Target = "_blank",
};

但是我喜欢这样做

var encodedAbsUrl = new string[] { "EncodedAbsUrl" };
var hf = new HyperLinkField
{
    HeaderText = "Link",
    DataTextField = "ServerUrl",
    NavigateUrl = clicker(encodedAbsUrl["{0}"]),
    Target = "_blank",
};


protected void clicker(string url)
{
    //...
}

那么你可以看到我的尝试不成功:)

任何建议表示赞赏

谢谢!

如果您将使用HyperLinkField,则不需要Clicker或任何回发事件,因为此字段将呈现为<a>标记.我使用HyperLink控件和LinkButton控件制作了一个示例示例,它将回发您的页面.

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        gv.DataSource = [YourDataSource];
        gv.DataBind();
    }
}
protected void Clicker(Object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Link")
    {
        Response.Redirect(e.CommandArgument.ToString());
    }
}
protected void gv_DataBinding(Object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        HyperLink hlink = e.Row.FindControl("hlink") as HyperLink;
        hlink.NavigateUrl = ((Person)e.Row.DataItem).NavUrl;
        hlink.Text = ((Person)e.Row.DataItem).NavUrl;
        hlink.Target = "_blank";

        LinkButton lnkButton = e.Row.FindControl("lnkButton") as LinkButton;
        lnkButton.Text = ((Person)e.Row.DataItem).NavUrl;
        lnkButton.CommandName = "Link";
        lnkButton.CommandArgument = ((Person)e.Row.DataItem).NavUrl;
    }
}

你GridView会喜欢这个

<asp:GridView runat="server" ID="gv" OnRowCommand="Clicker" OnRowDataBound="gv_DataBinding"
    AutoGenerateColumns="false">
    <Columns>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:HyperLink runat="server" ID="hlink"></asp:HyperLink>
                <asp:LinkButton runat="server" ID="lnkButton"></asp:LinkButton>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>
