我一直在努力了解正在发生的事情,我在网上搜索无济于事。
如何访问嵌套转发器内的按钮?我花了这么多时间研究/试验,我不明白发生了什么。
HTML标记:
<asp:Repeater runat="server" ID="repQuestionTopics">
....
<asp:Repeater ID="repQA" runat="server">
....
<strong>Was this article helpful?</strong>
<button class="button tiny secondary radius" runat="server"
CommandName="voteYes" id="btnVoteHelpfulYes">Yes</button>
<button class="button tiny secondary radius" runat="server"
CommandName="voteNo" ID="btnVoteHelpfulNo">No</button>
</asp:Repeater>
</asp:Repeater>
代码隐藏:
//Handles repQuestionTopics.ItemCommand
Public Sub repTopics_ItemCommand(Sender As Object, e As RepeaterCommandEventArgs)
If e.CommandName = "voteYes" Then
....
End If
End Sub
如何获得对repQA
的访问权限?出于某种原因,我的代码隐藏不会让我编写函数处理repQA.ItemCommand - 为什么?我试图通过使用类似的东西(添加OnClick)直接在asp端输入函数:
<button class="button tiny secondary radius" runat="server" OnClick="repTopics_ItemCommand"
CommandName="voteYes" id="btnVoteHelpfulYes">Yes</button>
当点击按钮voteYes
时,我希望能够进入数据库并更新计数器,以便我可以跟踪该问题答案的投票数和投票数。< / p>
无论我实施什么样的更改,当我点击按钮时页面刷新就会尝试让它工作,没有别的。

HTML标记:您必须将OnItemCommand
事件添加到内部转发器repAQ
:
<asp:Repeater ID="repQA" runat="server" OnItemCommand="repQA_ItemCommand">
<强>代码隐藏:强>
VB.Net:
Public Sub repQA_ItemCommand(Sender As Object, e As RepeaterCommandEventArgs)
// check for right name of command
If e.CommandName = "voteYes" Then
....
End If
End Sub
ASP.Net:
protected void repQA_ItemCommand(object source, RepeaterCommandEventArgs e)
{
// check for right name of command
if(e.CommandName == "voteYes")
{
....
}
}
