C# 无论如何，我在中继器datarow内设置了类，按数据ID查找，何时回发？
我想为中继器设置类，当doPostBack为我想要的那些数据ID设置类时，但dun noe可以/不能？ 下面的代码只是示例，显示：C# 无论如何，我在中继器datarow内设置了类，按数据ID查找，何时回发？,c#,asp.net,C#,Asp.net,我想为中继器设置类，当doPostBack为我想要的那些数据ID设置类时，但dun noe可以/不能？ 下面的代码只是示例，显示： <body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" EnablePartialRendering="true" runat="server" EnablePageMethods="true" />

如果要为每行绑定设置一个类，并且需要数据ID，那么最好的方法是在每行绑定时处理它：
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="dsInbox"
OnItemDataBound="Repeater1_ItemDataBound">
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="dsInbox"
OnItemDataBound="Repeater1_ItemDataBound">
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem))
{
MyType myItem = (MyType)e.Item.DataItem;
var dataId = myItem.DataId;
// Do whatever you need here.
}
}
