Question

我有如下所述的Gridview：

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="TrackingNumber" OnSelectedIndexChanged="GridView1_SelectedIndexChanged1"
DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="TrackingNumber" HeaderText="TID" ReadOnly="True" SortExpression="TrackingNumber" /> 
<asp:BoundField DataField="NationalCode" HeaderText="AID" SortExpression="NationalCode" />
<asp:BoundField DataField="ApplicantFName" HeaderText="AFName" SortExpression="ApplicantFName" />
<asp:BoundField DataField="ApplicantSex" HeaderText="ASex" SortExpression="ApplicantSex"/>
<asp:BoundField DataField="dateOfRegister" dataformatstring="{0:yyyy/MM/dd}" HeaderText="RegisterDate" SortExpression="dateOfRegister"/>
<asp:CommandField ButtonType="Image" SelectImageUrl="~/Admin/images/select.png"  ShowSelectButton="True" />
</Columns>
</asp:GridView>

在代码后面我编写了这段代码：

protected void GridView1_SelectedIndexChanged1(object sender, EventArgs e)
{
  Session["TID"] = GridView1.SelectedRow.Cells[0].Text;
  Response.Redirect("../Recruitment/InitPrint.aspx");
}

当用户点击命令字段按钮时，页面重定向到InitPrint.aspx，我的代码运行良好。但我希望InitPrint.aspx在新的标签页中打开，Session["TID"]将在那里阅读谢谢你的考虑。

Answer 1

请检查以下代码。希望它能帮到你

protected void GridView1_SelectedIndexChanged1(object sender, EventArgs e)
{ 
  Session["TID"] = GridView1.SelectedRow.Cells[0].Text;
  ScriptManager.RegisterStartupScript(Page, Page.GetType(), "popup", "window.open('page.aspx','_blank')", true);
}

Answer 2

没有直接的方法，你必须使用类似的东西：

protected void GridView1_SelectedIndexChanged1(object sender, EventArgs e)
{
    Session["TID"] = GridView1.SelectedRow.Cells[0].Text;
    ScriptManager.RegisterStartupScript(Page, typeof(Page), "OpenWindow", "window.open("'../Recruitment/InitPrint.aspx','_blank'");",true);
}

Answer 3

您可以将目标设置为空白。

Response.Write("<script>window.open('../Recruitment/InitPrint.aspx','_blank');</script>");

并访问该页面中的会话值。
