4后端代码: Imports System.Collections Public Class DataGridAccessValues Inherits System.Web.UI.Page Protected WithEvents MyDataGrid As System.Web.UI.WebControls.DataGrid Protected WithEvents GetValues As System.Web.UI.WebControls.Button Protected WithEvents ResultField As System.Web.UI.WebControls.Label #Region " Web 窗体设计器生成的代码 " '该调用是 Web 窗体设计器所必需的。 Private Sub InitializeComponent() End Sub Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init 'CODEGEN: 此方法调用是 Web 窗体设计器所必需的 '不要使用代码编辑器修改它。 InitializeComponent() End Sub #End Region Public Sub GetValues_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles GetValues.Click Dim Result As String = "" Dim dataGridItem As DataGridItem For Each dataGridItem In MyDataGrid.Items Dim Name As String = dataGridItem.Cells(0).Text Dim AgeField As TextBox = dataGridItem.FindControl("AgeField") Dim Age As Integer = System.Convert.ToInt64(AgeField.Text).ToString() Dim IsGraduateField As CheckBox = dataGridItem.FindControl("IsGraduateField") Dim IsGraduate As Boolean = IsGraduateField.Checked Dim Skills As String = "" Dim item As ListItem Dim CheckBoxList1 As CheckBoxList = dataGridItem.FindControl("CheckBoxList1") For Each item In CheckBoxList1.Items If item.Selected Then Skills = Skills + item.Value + "," End If Next Skills = Skills.TrimEnd(",") Dim RadioButtonList1 As RadioButtonList = dataGridItem.FindControl("RadioButtonList1") Dim Experience As String = RadioButtonList1.SelectedItem.Text Dim DropDownList1 As DropDownList = dataGridItem.FindControl("DropDownList1") Dim Degree As String = DropDownList1.SelectedItem.Text Result = Result + Name Result = Result + "[年龄:" + Age.ToString() + "]" Result += " " If IsGraduate Then Result += "已经毕业 , " Else Result += "没有毕业 , " End If Result += "技能:" + Skills + " , " Result += "经验: " + Experience + " , 和 " Result += "学位: " + Degree + "。" Result += "
