后台获取 Repeater里的ID
//前台
<asp:Repeater ID="Repeater1" runat="server" >
<ItemTemplate>
<a href="newsView.aspx?ClassID=<%#Eval("ID")%>" target="_blank">
<%#Eval("ID")%></a><%#Eval("标题")%><%#Eval("简介")%><%#Eval("来源")%>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="删除" /> <br/>
</ItemTemplate>
</asp:Repeater>
//后台
protected void Button1_Click(object sender, EventArgs e)
{
try
{
var obj = (from o in context.新闻
where o.ID == 这里应该添加什么才能获取Repeater里的ID值，完成删除功能
select o).Single();
context.DeleteObject(obj);
context.SaveChanges();
JS.Alert(this, "删除成功!");
}
catch (DataServiceRequestException ex)
{
throw new ApplicationException(
"删除时发生错误", ex);
}
}
[解决办法]
不是用Button1_Click事件
而是用Repeater_ItemCommand事件
具体参考代码:repeater增删改查
[解决办法]
<asp:Button ID="Button1" runat="server" Text="删除 OnClientClick="return confirm('确定要删除吗?');" CommandName="del" CommandArgument='<%#Eval("ID")%>' /> <br/>
protected void Repeater1_ItemCommand(object sender, RepeaterCommandEventArgs e)
{
if (e.CommandName == "del")
{
int id=Convert.ToInt32(e.CommandArgument);
}
}
