gridview行索引获取方法及实现代码

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。 
 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： 
 代码如下:

<asp:GridView ID="GridViewCosmetic" runat="server" Width="300" AutoGenerateColumns="false"> 
<Columns> 
<asp:TemplateField> 
<HeaderTemplate> 
ID 
</HeaderTemplate> 
<ItemTemplate> 
<%# Eval("ID")%> 
</ItemTemplate> 
</asp:TemplateField> 
<asp:TemplateField> 
<HeaderTemplate> 
Type 
</HeaderTemplate> 
<ItemTemplate> 
<%# Eval("Type")%> 
</ItemTemplate> 
</asp:TemplateField> 
<asp:TemplateField> 
<HeaderTemplate> 
Name 
</HeaderTemplate> 
<ItemTemplate> 
<%# Eval("Name")%> 
</ItemTemplate> 
</asp:TemplateField> 
<asp:TemplateField> 
<ItemStyle HorizontalAlign="Right" /> 
<HeaderTemplate> 
Weight 
</HeaderTemplate> 
<ItemTemplate> 
<%# Eval("Weight")%> 
</ItemTemplate> 
</asp:TemplateField> 
<asp:TemplateField> 
<HeaderTemplate> 
UM 
</HeaderTemplate> 
<ItemTemplate> 
<%# Eval("UM") %> 
</ItemTemplate> 
</asp:TemplateField> 
</Columns> 
</asp:GridView> 
 
当然得对这个控件，进行数据绑定，引用命名空间Imports Insus.NET 
 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： 
 代码如下:

<asp:TemplateField> 
<ItemTemplate> 
<asp:LinkButton ID="LinkButton1" runat="server" Text="选择" OnClientClick="return GetSelectedRow(this)" /> 
</ItemTemplate> 
</asp:TemplateField> 
 
上面html代码中，有一个OnClientClick="return GetSelectedRow(this)" 客户端事件。 
 代码如下:

<script type="text/javascript"> 
function GetSelectedRow(obj) { 
var row = obj.parentNode.parentNode; 
var rowIndex = row.rowIndex - 1; 
alert("你选择的行索引是：" + rowIndex); 
return false; 
} 
</script>
