本文介绍了ASP.NET中Repeater控件的ItemCreated和ItemCommand事件的实用案例，通过示例代码展示了如何利用这两个事件为每个项添加自定义属性及处理删除操作。

其实repeater的ItemCreated和ItemCommand事件也蛮好用的。

< asp:repeater id ="rptsortimgUp" runat ="server" OnItemCommand ="rptsortimgUp_ItemCommand" OnItemCreated ="rptsortimgUp_ItemCreated" >

< itemtemplate >

< a href ='<%# DataBinder.Eval(Container, "DataItem.f_url") % > ' target="_blank"> < img width ="16" height ="16" hspace ="3"

align ="absmiddle" src ='/Images/FileIcons/icon_<%# DataBinder.Eval(Container, "DataItem.f_type") % > .gif' border="0"> <%

# DataBinder.Eval(Container, "DataItem.f_name") %> </ a >< span style ="font-size:11px" >

[ <%

# DataBinder.Eval(Container, "DataItem.f_size", "{0:N0} Bytes") %> ] </ span >

< asp:ImageButton ID ="ibnsortimgUpDelete" ImageUrl ="/Images/icon_delete.gif" Width ="13" Height ="13" ImageAlign ="AbsMiddle" CommandName ="Delete" CommandArgument ='<%# DataBinder.Eval(Container, "DataItem.f_id") % > ' causesvalidation="False" runat="server">

</ asp:ImageButton >

</ itemtemplate >

< separatortemplate >

</ separatortemplate >

</ asp:repeater >

' 添加附件删除确认

Protected Sub rptsortimgUp_ItemCreated() Sub rptsortimgUp_ItemCreated(ByVal sender As Object, ByVal e As RepeaterItemEventArgs)

If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then

Dim myDeleteButton As ImageButton = CType(e.Item.FindControl("ibnsortimgUpDelete"), ImageButton)

myDeleteButton.Attributes.Add("style", "cursor:hand")

myDeleteButton.Attributes.Add("onclick", "return confirm('您确定要删除这个附件吗？')")

End If

End Sub ' rptsortimgUp_ItemCreated

' 删除附件

Connect()

Dim strID As String = e.CommandArgument.ToString()

FileUP.sortimgUp.Delete(conn, strID)

GetsortimgUp()

Disconnect()
