前端技术 2023/09/01 .NET

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\" %>
<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;}
}
}
