如何使用asp.net在新窗口中打开多个pdf文件

Question

在我的应用程序中有复选框的网格视图，选择多个复选框单击打印按钮在单独的窗口中打开pdf。 我的代码是

for (int i = 0; i < grdAdditionalInsured.Rows.Count; i++) 
{ 
    CheckBox chk = (CheckBox)grdAdditionalInsured.Rows[i].Cells[0].FindControl("chkAdditionalInsured"); 

    if (chk.Checked == true) 
    { 
     //**some code to get the id based on values** 
     string file = "/CertPrints/" + id.ToString() + ".pdf"; 
     String js = @"WindowPopup('" + file + "');"; 
     ScriptManager.RegisterStartupScript(this, this.GetType(), file, js, true); 
    } 
} 

上面的代码只显示最后一个记录pdf文件，请给我建议。

试试这个：

StringBuilder js = new StringBuilder(); 
for (int i = 0; i < grdAdditionalInsured.Rows.Count; i++) 
{ 
    bool checked = ((CheckBox)grdAdditionalInsured.Rows[i].Cells[0].FindControl("chkAdditionalInsured")).Checked; 
    if (checked) 
    { 
     //**some code to get the id based on values** 
     js.AppendFormat(@"WindowPopup('/CertPrints/{0}.pdf');",id)); 
    } 
} 
ScriptManager.RegisterStartupScript(this, this.GetType(), "filePopup", js.ToString(), true);
