SharePoint 2010可视化Webpart页面加载问题 [英] SharePoint 2010 visual webpart page load issue

问题描述

I am working on SharePoint 2010 visual webpart for the first time. I have some functions called on page load that gets value from list and then set variable values inside the "if (!IsPostBack){}" method.

单击按钮时，当我检查在页面加载中设置的变量值时，变量没有值.我已经在ASP更新面板中添加了所有控件.我尝试使用ViewState和httpContext，但没有任何效果.

On button click, when I check the variable values that I set on page load the variables has no value. I have add all the controls in the asp update panel. I tried using ViewState as well as httpContext but nothing worked.

如果我删除了"if(！IsPostBack)"，它之所以有效，是因为它在单击按钮时再次调用了页面加载事件.

If I remove the "if (!IsPostBack)" it works since it calls the page load event again on button click. 

任何帮助表示赞赏.
