为什么代码中Calendar1_DayRender没有执行，用断点监视了，没有经过那块语句？！

难道是Calendar空间需要设置特殊的属性？！

[以专业开发人员为伍]

为什么会执行这个方法呢？你随便复制一段代码，是不可能执行的。从你的描述来看，这段代码跟别的地方没有任何联系，凭什么会执行呢？

[EnForGrass]

你先搞清楚Calendar1_DayRender这个函数是干什么的？什么时候才会触发？

[jiuhexuan]

this.Calendar1.DayRender += new System.Web.UI.WebControls.DayRenderEventHandler(this.Calendar1_DayRender);
