gridview行索引獲取方法及實(shí)現(xiàn)代碼

更新時(shí)間：2013年01月14日 10:41:06 作者：

GridView行索引的獲取有利于對(duì)GridView行數(shù)據(jù)進(jìn)行操作(刪、改)等等，接下來(lái)介紹獲取方法，感興趣的朋友可以了解下，閱讀本文希望對(duì)你有幫助

Insus.NET為了演示這個(gè)例子，首先準(zhǔn)好數(shù)據(jù)，創(chuàng)建一個(gè)類別
Cosmetic.vb

 
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 

上面創(chuàng)建好的只是一對(duì)象，得需用數(shù)據(jù)填充，讓它有血有肉有靈魂。

復(fù)制代碼代碼如下:

 
Private Function GetData() As List(Of Cosmetic) 
Dim o As New List(Of Cosmetic) 
Dim c As New Cosmetic(1, "滋潤(rùn)霜", "玉蘭油", 50, "g") 
o.Add(c) 
Dim c1 As New Cosmetic(2, "滋潤(rùn)霜", "雅詩(shī)蘭黛", 100, "g") 
o.Add(c1) 
Dim c2 As New Cosmetic(3, "滋潤(rùn)霜", " 蘭蔻", 80, "g") 
o.Add(c2) 
Dim c3 As New Cosmetic(4, "滋潤(rùn)霜", "歐萊雅", 60, "g") 
o.Add(c3) 
Dim c4 As New Cosmetic(5, "滋潤(rùn)霜", "芭比波朗", 120, "g") 
o.Add(c4) 
Return o 
End Function 

在aspx網(wǎng)頁(yè)上放一個(gè)Gridview控件：

復(fù)制代碼代碼如下:

 
<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> 

當(dāng)然得對(duì)這個(gè)控件，進(jìn)行數(shù)據(jù)綁定，引用命名空間Imports Insus.NET

復(fù)制代碼代碼如下:

 
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 

接下來(lái)，我們開(kāi)始演示，在GridView控件最后一列，添加一列，選擇列：

復(fù)制代碼代碼如下:

 
<asp:TemplateField> 
<ItemTemplate> 
<asp:LinkButton ID="LinkButton1" runat="server" Text="選擇" OnClientClick="return GetSelectedRow(this)" /> 
</ItemTemplate> 
</asp:TemplateField> 

上面html代碼中，有一個(gè)OnClientClick="return GetSelectedRow(this)" 客戶端事件。

復(fù)制代碼代碼如下:

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