如何在新窗口中打开图像或PDF文件？ [英] How to open image or pdf file in a new window?

问题描述

我把它包含在文件名和文件（图像和PDF格式文件）的路径我用下，我把1图像buttoon模板领域的GridView。在该图像按钮即视图按钮点击我想在新窗口中打开选定的文件。

这是我的code：

 保护无效GVViewFile_SelectedIndexChanged（对象发件人，EventArgs的发送）
{
    INT ID = GVViewFile.SelectedIndex;
    字符串路径= GVViewFile.Rows [ID] .Cells [2] .Text.ToString（）;    的Response.Redirect（D：\\ UploadedAttachment \\ AT \\ MRD \\ AT0520130008_15-05-13-03-57-12.pdf）;    的Response.Write（＆LT;脚本＆gt;中）;
   的Response.Write（window.open（'+路径+'，'_空白'，'全屏= YES'））;
   //Response.Write（window.open（+路径+，_空白'））;
   回复于（＆下; /脚本＆gt;中）;}
 

但我无法在新窗口中打开。我的路径返回相同的值里面的Response.Write（）。磨片我只使用的Response.Write（图像/ UserDetails.pdf）; 为例，它会显示PDF page..but完整路径而不是索取。同时它显示了'\\'是的Response.Write（错误）; 那么如何使用实际的完整路径显示图像或PDF在新window..please帮助me.even了的window.open是给error.i不能写在window.open完整路径，因为我正在从选择路径gridview.help请....

我的GridView code：

 ＆LT; ASP：GridView控件ID =GVViewFile=服务器的AutoGenerateColumns =FALSE
        的DataSourceID =DSforgridviewonselectedindexchanged =GVViewFile_SelectedIndexChanged
        HeaderStyle-背景色=＃CC6600HeaderStyle-前景色=白

i have a gridview it contains file names and path of files (image and pdf format files) in that i used template field under that i put 1 image buttoon. on clicking of that image button i.e view button i want to open selected file in a new window.

here is my code :

protected void GVViewFile_SelectedIndexChanged(object sender, EventArgs e)
{
    int id = GVViewFile.SelectedIndex;
    string path = GVViewFile.Rows[id].Cells[2].Text.ToString();

    Response.Redirect("D:\UploadedAttachment\AT\MRD\AT0520130008_15-05-13-03-57-12.pdf");

    Response.Write("<script>");
   Response.Write("window.open('" + path + "','_blank', ' fullscreen=yes')");
   //Response.Write("window.open(" + path + ",'_blank')");
   Response.Write("</script>");

}

but i could not open in new window. my path returns same value as inside response.write(). whe i use just response.write("images/UserDetails.pdf"); as example it will show pdf page..but full path is not taking. also it shows '\' is wrong in response.write(); so how to use actual full path to display image or pdf in new window..please help me.even that window.open is giving error.i cannot write full path in window.open since i am getting selected path from gridview.help please....

my gridview code :

 <asp:GridView ID="GVViewFile" runat="server" AutoGenerateColumns="False" 
        DataSourceID="DSforgridview" onselectedindexchanged="GVViewFile_SelectedIndexChanged"
        HeaderStyle-BackColor="#CC6600" HeaderStyle-ForeColor="White" 
    PagerStyle-BackColor="#CC6600" PagerStyle-ForeColor="White" CellPadding="3" 
    CellSpacing="3" PagerStyle-Width="4" PagerStyle-Height="4" 
    BorderColor="#FF6600" BorderStyle="Solid">
        <Columns>
            <asp:TemplateField ShowHeader="false">
        <ItemTemplate>
            <asp:ImageButton ID="btnView" runat="server" 
                CausesValidation="False" CommandName="Select"
                ImageUrl="~/Images/view.gif" ToolTip="View File" />
        </ItemTemplate>
      </asp:TemplateField>

            <asp:BoundField DataField="FileType" HeaderText="FileType" 
                SortExpression="FileType" />
            <asp:BoundField DataField="FileLocationPath" HeaderText="FileLocationPath" 
                SortExpression="FileLocationPath" />
        </Columns>
    <HeaderStyle BackColor="#CC6600" ForeColor="White"></HeaderStyle>
    <EmptyDataTemplate>No Records Found.</EmptyDataTemplate>
    </asp:GridView>

解决方案

//In Default2.aspx
protected void LinkButton1_Click(object sender, EventArgs e)
    {
       Response.Write(string.Format("<script>window.open('{0}','_blank');</script>", "Default3.aspx"));
    }

//------------
//In Default3.aspx

protected void Page_Load(object sender, EventArgs e)
    {
        string path = Server.MapPath("~\\E:\\karthikeyan\\venky\\pdf\\aaaa.PDF");
        WebClient client = new WebClient();
        Byte[] buffer = client.DownloadData(path);
        if (buffer != null)
        {
            Response.ContentType = "application/pdf";
            Response.AddHeader("content-length", buffer.Length.ToString());
            Response.BinaryWrite(buffer);
        }
    }
