如何在ASP.NET下遍历指定页面上所有控件

序:把它写下的目的,是感觉这段代码会对一些朋友有所帮助!

#region 清空指定页面上所有的控件内容,public static void ClearAllContent()

///

/// 清空指定页面上所有的控件内容,包括TextBox,CheckBox,CheckBoxList,RadioButton,RadioButtonList。但是不清

/// 除如ListBox,DropDownList,因为这样的控件值对当前页面来说还可以用,一般这些控件里都是保存的字典数据。

/// 指定的页面

public static void ClearAllContent(System.Web.UI.Control page)

{

int nPageControls = page.Controls.Count;

for (int i = 0; i < nPageControls; i++)

foreach (System.Web.UI.Control control in page.Controls[i].Controls)

if (control.HasControls())

ClearAllText(control);

}

else

if (control is TextBox)

(control as TextBox).Text = "";

if (control is CheckBox)

(control as CheckBox).Checked = false;

if (control is RadioButtonList)

(control as RadioButtonList).SelectedIndex = -1;

if (control is RadioButton)

(control as RadioButton).Checked = false;

if (control is CheckBoxList)

foreach (ListItem item in (control as CheckBoxList).Items)

item.Selected = false;

}//if..else

}//foreach

}//for
