Question

我知道打印整个GridView并不是一个太大的挑战。但是，我希望打印一个特定的行。不仅仅是它如何出现在gridview中，而是所有行单元格在页面上连接在一起。每行都是一个简历，有一个ID，一个名称列，一个标题列，一个正文列，一个作者列和一个创建日期的列。对于body列，仅显示前50个字符 - 因此只显示在显示的行时将无效。

我希望能够打印行并对其进行格式化，使其看起来像一个实际的简历：

Name     Title       Date

         Body


ResumeID

这可能吗？

我还要为每一行添加一个打印图标，可以触发onclick或onclientclick事件。

自己想出来，基本上只是将行注入gridview下面的隐藏div，然后打印出它的内部html。我确定还有其他方法，但效果很好：

ASPX：

<asp:Button ID="btnToggleViews" runat="server" Text="Show Bounces" OnClick="btnToggleViews_Click" />
    <asp:Label ID="lblParentID" runat="server" Visible="false"></asp:Label><asp:ImageButton ID="IBPrintGridview" runat="server" OnClick="IBPrintGridview_Click1" ImageUrl="~/images/printer.gif" Height="26" Width="26" />
    <asp:Label ID="Label1" CssClass="Label1" runat="server" Text="0" Visible="false" Font-Bold="true" BorderColor="#507CD1" BorderWidth="2.5" ForeColor="White" BackColor="#507CD1"></asp:Label>
    <div id="GridViewData">
        <asp:GridView ID="GVResume" runat="server" AutoGenerateColumns="False" Width="100%"
             HeaderStyle-BorderWidth="1" HeaderStyle-BorderStyle="Solid"
            OnRowDataBound="GVResume_OnRowDataBound"
            OnRowCommand="GVResume_OnRowCommand">
            <Columns>
                <asp:TemplateField ItemStyle-Wrap="false" ItemStyle-VerticalAlign="Top" ItemStyle-HorizontalAlign="Left"  HeaderText="ID" Visible="false">
                    <ItemTemplate>
                        <asp:Label ID="lblID" runat="server" Text='<%# Eval("ID") %>' />
                    </ItemTemplate>

       if(e.CommandName == "Print")
        {

            Label3.Text = Argument;

            PrintIt();

        }
