ObjectDataSource不调用SelectCount方法
你能帮我找到问题吗：
实现简单的DataGrid和ObjectDataSource捆绑包
由于某种原因，我想通过分页我的.aspx文件
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:DataGrid ID="DataGrid1" runat="server"
DataSourceID="ObjectDataSource1"
AllowPaging="true"
PageSize="2" >
</asp:DataGrid>
<asp:ObjectDataSource
runat="server"
ID="ObjectDataSource1"
TypeName="WebApplication1.AssetComments"
SelectMethod="SelectMethod2"
StartRowIndexParameterName="startRowIndex"
MaximumRowsParameterName="maximumRows"
SortParameterName="sortParameter"
SelectCountMethod="GetCount" EnablePaging="True"
/>
</form>
</body>
</html>
我的AssetComments类
namespace WebApplication1
{
public class AssetComments
{
public List<RSSFeed> SelectMethod2(int startRowIndex, int maximumRows, string sortParameter)
{
return SelectMethod2().Skip(startRowIndex).Take(maximumRows).ToList();
}
public List<RSSFeed> SelectMethod2()
{
List<RSSFeed> ret = new List<RSSFeed>(2) { new RSSFeed("11", "1111111"), new RSSFeed("22", "2222222") };
return ret;
}
public int GetCount()
{
return 55;
}
}
public class RSSFeed
{
public string Title { get; set; }
public string Description { get; set; }
public RSSFeed(string title, string description)
{
Title = title;
Description = description;
}
}
}
asp.net cals SelectMethod2带 (0,0,"") 参数并且不调用 GetCount。
请帮我找到问题
谢谢
