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 }
