Syncfusion餅圖錯誤

Question

我有一個餅圖的要求。 我使用syncfusion，並在.aspx頁中注冊，並在.aspx.cs頁中使用庫。 雖然我嘗試運行它顯示錯誤。 我該如何解決？

我的.aspx代碼：

我們已經分析了查詢。 我們已嘗試使用提供的代碼段復制報告的方案，但是很遺憾，我們無法復制該方案，因為我們懷疑在您的末端未在web.config文件中正確引用了程序集。 我們准備了一個示例，其中已針對您的代碼段繪制了餅圖。 由於我們不知道您的數據源，因此我們將隨機數據提供給圖表並進行了渲染。 請按照以下步驟呈現圖表。

下面列出了呈現圖表控件所需的DLL。

• Syncfusion.Core.dll
• Syncfusion.Chart.Base.dll
• Syncfusion.Chart.Web.dll
• Syncfusion.Shared.Base.dll
• Syncfusion.Shared.Web.dll
• Syncfusion.Tools.Web.dll

然后在Web.config文件中添加以下名稱空間。

<configuration> 
  <system.web> 
    <compilation > 
      <assemblies> 
        <add assembly="Syncfusion.Chart.Web" /> 
        <add assembly="Syncfusion.Chart.Base" /> 
        <add assembly="Syncfusion.Shared.Web" /> 
        <add assembly="Syncfusion.Tools.Web" /> 
        <add assembly="Syncfusion.Shared.Base" /> 
        <add assembly="Syncfusion.Core" /> 
      </assemblies> 
    </compilation> 
  </system.web> 
</configuration> 

在Web.config文件中添加處理程序以在網頁中呈現圖表。

<handlers> 
      <add name="syncfusion_generate" path="syncfusion_generate.ashx" verb="*"  
                type="Syncfusion.Web.UI.WebControls.Chart.ChartWebHandler,Syncfusion.Chart.Web"/> 
</handlers>
