我正在嘗試使用 Visual Studio (2015) 提供的 asp:Chart 控制元件在我的頁面中創建圖表。但由于某種原因，我無法在代碼隱藏頁面上配置圖表本身（例如嘗試為圖表設定資料源）。
這是我在頁面上的內容：
`
<%@ Page Title="GERM | Dashboard Analista" Language="C#" AutoEventWireup="true" CodeBehind="DashboardAnalista.aspx.cs" Inherits="WebApplication1.Auditores.Auditorias" MasterPageFile="~/Analistas.Master" Async="true" %>

當我嘗試修改時，假設“Chart11”智能感知不會自動完成我可以在 Chart11 上修改的不同屬性，Chart2 也是如此
這就是我在代碼背后的內容：
`
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;
using System.Web.UI.DataVisualization.Charting;
namespace WebApplication1.Analistas
{
public partial class DashboardAnalista : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
chart11 //IntelliSense is not autocompleting!!
}
}
}
`
我的 aspx.designer 顯示了所有圖表控制元件，所以這不是 'runat=server' 類問題中的錯誤。
我不知道我是否缺少參考或未配置的東西，但智能感知對我來說不會自動完成這一事實。
- 更改 ID 以強制設計器頁面重新運行
- 洗掉圖表并重新創建新圖表，同樣的情況也會發生。
- 檢查缺少的“runta=server”
uj5u.com熱心網友回復：
我已經發現了問題：
頁面第 1 行：
<%@ Page Title="GERM | Dashboard Analista" Language="C#" AutoEventWireup="true" CodeBehind="DashboardAnalista.aspx.cs" Inherits="WebApplication1.Auditores.Auditorias" MasterPageFile="~/Analistas.Master" Async="true" %>
Inherits 屬性指向我網站中的其他頁面。一旦我將它指向正確的那個。我能夠“呼叫” .cs 頁面中的圖表：
