在新标签页或窗口中重定向 [英] redirect in new tab or window

问题描述

我想在新窗口中重定向页面但是无法执行此操作

说明 - 我有gridview其中我已经按下了按钮字段，点击此按钮下载指定行将开始，然后我编码responce.redirect这个文件，但我想在新的选项卡或窗口，所以PLZ告诉我它是如何设置的

 <   asp：GridView    < span class =code-attribute> ID   =  GridView1    runat   = 服务器  
   
                               AutoGenerateColumns   =  False  
   
                               DataSourceID   =  SqlDataSource3  
   
                               onrowcommand   =  GridView1_RowCommand  
   
            < span class =code-attribute>                   DataKeyNames   =  DocID  
   
                    < span class =code-attribute>                                      高度  =  50px   宽度  =  50px    AllowSorting   =  True >  
 <  列 >  
 <   asp： BoundField     DataField   =  DocID    HeaderText   =  DocID  
   
                                   InsertVisible   =  False  
   
                                   ReadOnly   =  True  
   
                                   SortExpression   =  DocID   可见  = 错误    /  >  <   asp：ButtonField     ButtonType   = 图片  
   
                                < span class =code-attribute> ImageUrl   = 〜/ download-button.jpg  
   
                                 CommandName   = 下载  
   
                                 HeaderText   = 下载    ControlStyle -Height   =  20px  
   
                 ControlStyle-Width   =   20px   >  
 <   ControlStyle    高度  =  20px   宽度  =  20px >  <   / ControlStyle  >  
 <   / asp：ButtonField  >  
 <   /列  >  
 <   / asp：GridView  >  

和cs页面





<前lang =cs> 受保护 void GridView2_RowCommand（ object sender，GridViewCommandEventArgs e）
{
if （e.CommandName == 下载）
{
string fileName = string .Empty;
int index = Convert.ToInt32（e.CommandArgument）;
GridViewRow row = GridView2.Rows [index];
int documentID = Convert.ToInt32（GridView2.DataKeys [index] .Value）;
SqlConnection con = new SqlConnection（ Server =。; Database = E_Notes; integrated Security = true）;
// SqlConnection con = new SqlConnection（ConfigurationManager.ConnectionStrings [ConnectionString]。ConnectionString）;
SqlCommand cmd = new SqlCommand（ SELECT DocName FROM SaveDoc WHERE DocID = + documentID，con）;
con.Open（）;
SqlDataReader dReader = cmd.ExecuteReader（）;
while （dReader.Read（））
{
fileName = dReader [ DocName]。ToString（）;
byte [] documentBinary =（ byte []）dReader [ DocData];
FileStream fStream = new FileStream（Server.MapPath（ ../ Docs /）+ @ \ + fileName ，FileMode.Create）;
fStream.Write（documentBinary， 0 ，documentBinary.Length）;
fStream.Close（）;
fStream.Dispose（）;
}
con.Close（）;
Response.Redirect（ @ .. \Docs \ + fileName）;
}
}

你不能是简短的答案。浏览器是唯一可以打开一个新窗口的东西。



您可以做的是在响应中发送一大块html，其中包含与您网址的链接作为一个href，target =_ blank和一个伪造点击的表单的javascript onload。如果这不起作用则使用window.open（url）;

 response.write（ < script>）; 
 response.write（  window.open（'page.html'，'_ blank'））; 
 response.write（ < / script>）; 

I want to redirect a page in new window but not able to do this
explanation-i have gridview in which i have taken button field,on click of this button the downloading of the specified row will starts and after that i code responce.redirect this document but i want in new tab or window so plz tell me how it is posible

<asp:GridView ID="GridView1" runat="server"

              AutoGenerateColumns="False"

              DataSourceID="SqlDataSource3"

              onrowcommand="GridView1_RowCommand"

              DataKeyNames="DocID"

                            Height="50px" Width="50px" AllowSorting="True">
<Columns>
<asp:BoundField DataField="DocID" HeaderText="DocID"

                InsertVisible="False"

                ReadOnly="True"

                SortExpression="DocID" Visible="False" /><asp:ButtonField ButtonType="Image"

               ImageUrl="~/download-button.jpg"

               CommandName="Download"

               HeaderText="Download" ControlStyle-Height="20px"

                       </asp:GridView>

and on cs page

protected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e)
   {
       if (e.CommandName == "Download")
       {
           string fileName = string.Empty;
           int index = Convert.ToInt32(e.CommandArgument);
           GridViewRow row = GridView2.Rows[index];
           int documentID = Convert.ToInt32(GridView2.DataKeys[index].Value);
           SqlConnection con = new SqlConnection("Server=.;Database=E_Notes;integrated Security=true");
           //SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
           SqlCommand cmd = new SqlCommand("SELECT DocName FROM SaveDoc WHERE DocID = " + documentID, con);
           con.Open();
           SqlDataReader dReader = cmd.ExecuteReader();
           while (dReader.Read())
           {
               fileName = dReader["DocName"].ToString();
               byte[] documentBinary = (byte[])dReader["DocData"];
               FileStream fStream = new FileStream(Server.MapPath("../Docs/") + @"\" + fileName, FileMode.Create);
               fStream.Write(documentBinary, 0, documentBinary.Length);
               fStream.Close();
               fStream.Dispose();
           }
           con.Close();
           Response.Redirect(@"..\Docs\" + fileName);
       }
   }

Hi,

Have a look here:

You can''t is the short answer. The browser is the only thing that can open up a new window.

What you can do is send a chunk of html down the response that has a link with your url as an href, target="_blank" and a chunk of javascript onload of the form that fakes a click. If this doesn''t work then use a window.open(url);

response.write("<script>");
response.write("window.open('page.html','_blank')");
response.write("</script>");
