我有一个在ASP.NET中实现的数据表。我想在页面上实时或接近实时显示对此基础数据的更改。我该怎么办？
我的模特：
public class BoardGame
{
public int Id { get; set;}
public string Name { get; set;}
public string Description { get; set;}
public int Quantity { get; set;}
public double Price { get; set;}
public BoardGame() { }
public BoardGame(int id, string name, string description, int quantity, double price)
{
Id=id;
Name=name;
Description=description;
Quantity=quantity;
Price=price;
}
}
代替此示例的实际数据库，我将把数据存储在Application变量中。我将其Application_Start植入我的Global.asax.cs函数中。
var SeedData = new List<BoardGame>(){
new BoardGame(1, "Monopoly","Make your opponents go bankrupt!", 76, 15),
new BoardGame(2, "Life", "Win at the game of life.", 55, 13),
new BoardGame(3, "Candyland", "Make it through gumdrop forrest.", 97, 11)
};
Application["BoardGameDatabase"] = SeedData;
如果使用的是Web窗体，则将使用中继器显示数据。
<h1>Board Games</h1>
<asp:Repeater runat="server" ID="BoardGameRepeater" ItemType="RealTimeDemo.Models.BoardGame">
<HeaderTemplate>
<table border="1">
<tr>
<th>Id</th>
<th>Name</th>
<th>Description</th>
<th>Quantity</th>
<th>Price</th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td><%#: Item.Id %></td>
<td><%#: Item.Name %></td>
<td><%#: Item.Description %></td>
<td><%#: Item.Quantity %></td>
<td><%#: Item.Price %></td>
</tr>
</ItemTemplate>
<FooterTemplate></table></FooterTemplate>
</asp:Repeater>
并在后面的代码中加载该数据：
protected void Page_Load(object sender, EventArgs e)
{
BoardGameRepeater.DataSource = Application["BoardGameDatabase"];
BoardGameRepeater.DataBind();
}
