gridview行索引获取方法及实现代码

Insus.NET为了演示这个例子，首先准好数据，创建一个类别
Cosmetic.vb

复制代码 代码如下:

Imports Microsoft.VisualBasic
Namespace Insus.NET
Public Class Cosmetic
Private _ID As Integer
Private _Type As String
Private _Name As String
Private _Weight As Decimal
Private _UM As String
Public Property ID As Integer
Get
Return _ID
End Get
Set(value As Integer)
_ID = value
End Set
End Property
Public Property Type As String
Get
Return _Type
End Get
Set(value As String)
_Type = value
End Set
End Property
Public Property Name As String
Get
Return _Name
End Get
Set(value As String)
_Name = value
End Set
End Property
Public Property Weight As Decimal
Get
Return _Weight
End Get
Set(value As Decimal)
_Weight = value
End Set
End Property
Public Property UM As String
Get
Return _UM
End Get
Set(value As String)
_UM = value
End Set
End Property
Public Sub New()
End Sub
Public Sub New(id As Integer, type As String, name As String, weight As Decimal, um As String)
Me._ID = id
Me._Type = type
Me._Name = name
Me._Weight = weight
Me._UM = um
End Sub
End Class
End Namespace

上面创建好的只是一对象，得需用数据填充，让它有血有肉有灵魂。

复制代码 代码如下:

Private Function GetData() As List(Of Cosmetic)
Dim o As New List(Of Cosmetic)
Dim c As New Cosmetic(1, "滋润霜", "玉兰油", 50, "g")
o.Add(c)
Dim c1 As New Cosmetic(2, "滋润霜", "雅诗兰黛", 100, "g")
o.Add(c1)
Dim c2 As New Cosmetic(3, "滋润霜", " 兰蔻", 80, "g")
o.Add(c2)
Dim c3 As New Cosmetic(4, "滋润霜", "欧莱雅", 60, "g")
o.Add(c3)
Dim c4 As New Cosmetic(5, "滋润霜", "芭比波朗", 120, "g")
o.Add(c4)
Return o
End Function

在aspx网页上放一个Gridview控件：

复制代码 代码如下:

ID


<%# Eval("ID")%>




Type


<%# Eval("Type")%>




Name


<%# Eval("Name")%>





Weight


<%# Eval("Weight")%>




UM


<%# Eval("UM") %>

当然得对这个控件，进行数据绑定，引用命名空间Imports Insus.NET

复制代码 代码如下:

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
If Not IsPostBack Then
Data_Binding()
End If
End Sub
Private Sub Data_Binding()
Me.GridViewCosmetic.DataSource = GetData()
Me.GridViewCosmetic.DataBind()
End Sub

接下来，我们开始演示，在GridView控件最后一列，添加一列，选择列：

复制代码 代码如下:

上面html代码中，有一个OnClientClick="return GetSelectedRow(this)" 客户端事件。

复制代码 代码如下:
