This article illustrates the way in ASP. NET to access the values of all controls in DataGrid. Share it for your reference, as follows: 


<%@ Page Language="C#" %>
<%@ import Namespace="System.Collections" %>
<script runat="server">
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;}
}
}
