本文实例讲述了ASP.NET中访问DataGrid中所有控件值的方法。分享给大家供大家参考，具体如下：

<%@ Page Language="C#" %>

<%@ import Namespace="System.Collections" %>

void Page_Load(Object sender, EventArgs e) {

if(!Page.IsPostBack){

ArrayList data = new ArrayList();

data.Add(new Person("Tom",33,true));

data.Add(new Person("Jhon",39,false));

data.Add(new Person("Mark",20,false));

data.Add(new Person("Linda",27,true));

MyDataGrid.DataSource = data;

MyDataGrid.DataBind();

}

void GetValues_Click(Object sender, EventArgs e) {

String Result = "";

foreach(DataGridItem dataGridItem in MyDataGrid.Items){

//Get name from cell[0]

String Name = dataGridItem.Cells[0].Text;

//Get text from textbox in cell[1]

String Age = ((TextBox)dataGridItem.FindControl("AgeField")).Text;

//Get Checked property of Checkbox control

bool IsGraduate = ((CheckBox)dataGridItem.FindControl("IsGraduateField")).Checked;

// get Values from Checkboxlist

String Skills = "";

foreach(ListItem item in ((CheckBoxList)dataGridItem.FindControl("CheckBoxList1")).Items){

if (item.Selected){

Skills += item.Value + ",";

}

Skills = Skills.TrimEnd(',');

//Get RadioButtonList Selected text

String Experience = ((RadioButtonList)dataGridItem.FindControl("RadioButtonList1")).SelectedItem.Text;

//Get DropDownList Selected text

String Degree = ((DropDownList)dataGridItem.FindControl("DropDownList1")).SelectedItem.Text;

// Build String to show result.

Result += Name;

Result += " [Age -" + Age + "] ";

if (IsGraduate){

Result += "Is Graduate , ";

}else{

Result += "Is not Graduate , ";

}

Result += "Has Skills[" + Skills + "] , ";

Result += "Has " + Experience + " Experience , And " ;

Result += "Has " + Degree + " Degree." ;

Result += "<br>";

}

ResultField.Text = Result;

}

class Person{

String _Name;

int _Age;

bool _IsGraduate;

public Person(String name,int age, bool isGraduate){

_Name = name;

_Age = age;

_IsGraduate = isGraduate;

}

public String Name{

get{return _Name;}

}

public int Age{

get{return _Age;}

}

public bool IsGraduate{

get{return _IsGraduate;}

}
