[英]asp.net Button type link should open on new window
using c# .net4.0 使用c#.net4.0
I am aware the asp.net button with in the gridview of type link does a post to the same page when clicked, i need make several manipualtion on server side before actually redirecting user to an external site hence i can't use Hyperlinkfield. 我知道类型链接的gridview中的asp.net按钮在单击时会在同一页面上发帖,在实际将用户重定向到外部站点之前,我需要在服务器端进行多次操作,因此我无法使用Hyperlinkfield。 What i need now is the external site htm page should open up in sperate window.
我现在需要的是应该在单独的窗口中打开外部站点htm页面。 I tried the following which works but source site's fonts get bigger???
我尝试了以下可行的方法,但是源站点的字体变大了???
heres what i tried 这是我尝试过的
Response.Write("<script>");
Response.Write("window.open('http://www.google.co.uk','_blank')");
Response.Write("</script>");
Response.End();
may be i need a refresh source site?? 可能我需要刷新源站点吗?
Thanks 谢谢
@ Curt Here is the code for Hyperlink i tired @ Curt这是我累的超链接代码
on page load added new button on gridview 页面加载在gridview上添加了新按钮
HyperLinkField LinksBoundField = new HyperLinkField();
string[] dataNavigateUrlFields = {"link"};
LinksBoundField.DataTextField = "link";
LinksBoundField.DataNavigateUrlFields = dataNavigateUrlFields;
LinksBoundField.DataNavigateUrlFormatString = "http://" + Helper.IP + "/" + Helper.SiteName + "/" + Helper.ThirdPartyAccess + "?dispage={0}&token=" + Session["Token"];
LinksBoundField.HeaderText = "Link";
LinksBoundField.Target = "_blank";
GridViewLinkedService.Columns.Add(LinksBoundField);
GridViewLinkedService.RowDataBound += new GridViewRowEventHandler(grdView_RowDataBound);
to append external values (refe and appid) to navigate url
protected void grdView_RowDataBound(object sender, GridViewRowEventArgs e)
{
string strvalue = "";
string strvalue1 = "";
string strRef = "";
string strAppId = "";
foreach (GridViewRow row in GridViewLinkedService.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
//reference and appid
strAppId = row.Cells[0].Text;
strRef = row.Cells[1].Text;
HyperLink grdviewLink = (HyperLink)row.Cells[5].Controls[0];
strvalue = grdviewLink.NavigateUrl;
strvalue1 = Regex.Replace(strvalue, "(.*dispage\\=).*/(services.*)", "$1$2");
grdviewLink.NavigateUrl = "~/My Service/FillerPage.aspx?nurl=" + strvalue1 + "&AppID=" + strAppId.ToString() + "&Ref=" + strRef.ToString();
}
}
}
public partial class FillerPage : System.Web.UI.Page
{
private string refno = null;
private string appid = null;
private string nurl = null;
private string strvalue1 = "";
private string newtoken = "";
protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString.GetValues("AppID") != null)
{
appid = Request.QueryString.GetValues("AppID")[0].ToString();
}
if (Request.QueryString.GetValues("Ref") != null)
{
refno = Request.QueryString.GetValues("Ref")[0].ToString();
}
if (Request.QueryString.GetValues("nurl") != null)
{
nurl = Request.QueryString.GetValues("nurl")[0].ToString();
}
while receiving the long url it gets messed up(same query multiple times and all jumbled up)?????
is there a better way to pass parameters ??? 有没有更好的方法来传递参数?
you need to register script not response.write 您需要注册脚本而不是response.write
so the code for you is : 所以您的代码是:
ClientScript.RegisterStartupScript(this.GetType(), Guid.NewGuid().ToString(), "<script language=JavaScript>window.open('http://www.google.co.uk','_blank')</script>");
Read more : ClientScriptManager.RegisterStartupScript . 阅读更多: ClientScriptManager.RegisterStartupScript 。
In a situation where I need to run server side code, before then opening a new page, I sometimes create a Generic Handler File
and link to this with a HyperLink, passing variables as Query Strings. 在需要运行服务器端代码的情况下,在打开新页面之前,有时会创建一个
Generic Handler File
并使用HyperLink链接到该Generic Handler File
,并将变量作为查询字符串传递。 Therefore something like: 因此类似:
/MyGenericFile.ashx?id=123
In this file, I would have some scripting that needs to be carried out, followed by a Response.Redirect()
. 在此文件中,我将需要执行一些脚本,然后执行
Response.Redirect()
。
As long as the HyperLink is set to target="_blank"
, the user won't even know they've been to a generic file, which is then redirected. 只要将HyperLink设置为
target="_blank"
,用户甚至都不会知道他们曾经使用过通用文件,然后将其重定向。 It will appear as they've opened a new link. 当他们打开新链接时,它将显示。
Therefore the process would be: 因此,该过程将是:
.ashx
file .ashx
文件的链接 Response.Redirect()
is ran Response.Redirect()
已运行 www.google.com
in your example) www.google.com
) I believe this same process is used by advert management systems to help track clicks. 我相信广告管理系统会使用相同的过程来帮助跟踪点击次数。
您可以使用ClientScriptManager.RegisterStartupScript注册脚本以在页面加载时运行。
