動態生成雷達圖--Radarhtml

效果圖：this

aspx頁面代碼：spa

1 <ext:Panel ID="ResultPanel" Border="true" runat="server">
2     <Items>
3     </Items>
4 </ext:Panel>

由於是動態生成圖，因此只須要一個容器裝載（Panel）；.net

aspx.cs代碼插件

 1         [DirectMethod(Timeout = 2000000)]//限制執行超時時間
 2         protected void ReloadData(object sender, DirectEventArgs e)

 7             ResultPanel.Add(Panel);//把生成帶有Radar圖的Panel加到容器裏
 8             ResultPanel.ReRender();//從新裝載容器（容器位置不變）
 9             // ResultPanel.Render();從新裝載容器（容器位置根據添加子元素的順序加載）
10         }
