一、
Asp.Net Page页面中访问所有控件的属性为:
Page.Controls
控件的结构是树结构。
二、获取指定类型所有控件实例:
1.递归方法定义:
??private void GetControlList<T>(ControlCollection controlCollection, List<T> resultCollection) where T : Control ???{ ???????foreach (Control control in controlCollection) ???????{ ???????????//if (control.GetType() == typeof(T)) ???????????if (control is T) // This is cleaner ???????????????resultCollection.Add((T)control); ???????????if (control.HasControls()) ???????????????GetControlList(control.Controls, resultCollection); ???????} ???}
2.使用调用:
???List<Literal> allControls = new List<Literal>(); ???GetControlList<Literal>(Page.Controls, allControls); ???foreach (var childControl in allControls) ???{ ???????//call for all controls of the page ???}
