服务器控件Repeater

在使用aspx开发中,如果一个页面做纯数据展示,Repeater会比GridView更适合,因为它是轻量级的

下面是最基本的用法:

 aspx:

<table>
<asp:Repeater ID="repeater1" runat="server" EnableViewState="false" OnItemCommand="repeater1_ItemCommand">
<HeaderTemplate>
<tr><th>Id</th><th>Name</th><th>Pwd</th><th>Type</th><th>删除</th></tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td><%#Eval("Id")%></td>
<td><%#Eval("Name")%></td>
<td><%#Eval("Pwd")%></td>
<td><%#Eval("Type")%></td>
<td>
<asp:Button ID="btnDelete" runat="server" Text="删除" CommandName="Delete" CommandArgument='<%#Eval("Id")%>'/>
</td>
</tr>
</ItemTemplate>
</asp:Repeater>
</table>

 aspx.cs:

protected void Page_Load(object sender, EventArgs e)
{
BindList();
}

private void BindList()
{
ManagerInfoBLL bll = new ManagerInfoBLL();
repeater1.DataSource = bll.GetManagerInfoList();
repeater1.DataBind();
}

protected void repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
int id = Convert.ToInt32(e.CommandArgument); //拿到前台传递过来的Id
}
}

1.ItemTemplate其实就是foreach遍历

2.在这里可以禁用ViewState,使页面性能更好
