我要评论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>
