推荐答案

要确定是否选中了复选框，您需要首先使用FindControl [ ^ ]方法. 假设这是您的转发器，而Button2是您的导出到PDF按钮: For determining whether the Checkboxes are checked, you need to look for the control first by using FindControl[^] method of the repeater item. Suppose this is your repeater and Button2 is your export to PDF button: <asp:Button ID="Button2" runat="server" onclick="Button2_Click" /><br /> <asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand"> <ItemTemplate> <asp:CheckBox ID="Checkbox1" runat="server" /> <asp:Label ID="Label2" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "Name")%>' /> <br /> </ItemTemplate> </asp:Repeater>

您可以通过实现类似于以下内容的方法来实现您的目标.

You can accomplish your goal by implementing something similar to the one below.

protected void Button2_Click(object sender, EventArgs e) { foreach (RepeaterItem item in Repeater1.Items) { if (((CheckBox)item.FindControl("Checkbox1")).Checked) { //Do something } } }

现在可以过滤选中的项目了，您可以使用一些第三方API，例如 ITextSharp [ ^ ]即可将数据导出到PDF. 此处 [ ^ ]是关于API入门的好教程.

Now that can filter checked items, you can use some third party API like ITextSharp[^] to export data to PDF. Here[^] is a good tutorial for starters about the API.
