问题：
平台：visual studio 2008
要求：gridview中当前行<asp:TextBox></asp:TextBox>有值时，对应的<asp:CheckBox></asp:CheckBox>自动勾选（离开文本框时判断也行）
Insus.NET解决效果：
Order类别：
View Code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
/// <summary>
/// Summary description for Orders
/// </summary>
namespace Insus.NET
{
public class Order
{
private int _Order_nbr;
public int Order_nbr
{
get { return _Order_nbr; }
set { _Order_nbr = value; }
}
public Order()
{
//
// TODO: Add constructor logic here
//
}
}
}
GridView Html代码：
View Code
<asp:GridView ID="GridViewOrders" runat="server" AutoGenerateColumns="false" Width="330px" OnRowCreated="GridViewOrders_RowCreated">
<Columns>
<asp:TemplateField>
<HeaderTemplate>
Order Number
</HeaderTemplate>
<ItemTemplate>
<%# Eval("Order_nbr") %>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<HeaderTemplate>
Selected
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBoxSelected" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<HeaderTemplate>
Unit Price
</HeaderTemplate>
<ItemTemplate>
<asp:TextBox ID="TextBoxUnitPrice" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
