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:

<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

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:

<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。

复制代码 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>
