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带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);
    }
}

以上代码只显示最后记录的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);
