请帮助我解决一个问题。 我有一个仪表板即时尝试。此仪表板使用javascript和html。对于仪表板上的特定小部件，我需要将值动态返回给控件的data属性。
如果我输入一个整数作为值，则图表会呈现好的状态，但是当我尝试使用页面后面的变量动态地执行此操作时，它根本不会呈现任何内容。 请问我可以尝试什么？我将附加仪表板文件以及我遇到挑战的位置的片段。
请协助code behind page setting an integer variable to 45 [显示动态变量调用的演示面板文件

答案 0 :(得分：0)
我相信您的问题与列出的here相同。
在初次访问页面后，JavaScript不会在回发时运行，无法根据值后面的更新代码对窗口小部件进行更改。
您需要找到一种方法，以在更新c＃值后回发后重新调用JavaScript，从而从JavaScript重新加载小部件。
然后您可以使用以下代码片段aspx文件将变量/方法后面的代码值插入呈现的页面：
<%= PAGENAME.MethodToGetValue() %>
考虑可能通过Ajax调用使用WebMethod来满足您的需求。
