我的 asp 页面上有一个 GridView。我想通过单击按钮来更改 LinqDataSource。这是因为我有 2 个数据库视图,您必须能够根据需要查看其中一个视图。当我尝试将 GridView 绑定到我的任何 LinqDataSource' 时,我的问题是没有任何反应。
我的 C# 代码:
protected void Page_Load(object sender, EventArgs e)
{
this.Grid.DataSource = lqds_Grid1;
this.Grid.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
if (this.Grid.DataSource == lqds_Grid1)
{
this.Grid.DataSource = lqds_Grid2;
this.Grid.DataBind();
}
else
{
this.Grid.DataSource = lqds_Grid1;
this.Grid.DataBind();
}
}
我的 asp 代码:
<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
CodeBehind="Default.aspx.cs" Inherits="AddressReporting._Default" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
