UpdatePanel 内的中继器内的 ASP.NET 按钮不会触发!
ASP.NET 3.5 SP 1 / Visual Studio 2008 V 9.x RTM
我试图在更新面板内的中继器内触发一个按钮。 我不会。我尝试在 ContentTemplate 外部和内部添加触发器 UpdatePanel 无济于事:
<Triggers>
<asp:AsyncPostBackTrigger ControlID="BtnAddStatus" EventName="Click" />
</Triggers>
事实上,AsyncPostBackTrigger 的 ControlID 始终为红色,并告诉我“无法解析符号”。无论我在页面的哪个位置放置触发器,情况似乎都是如此。
我读过通过将按钮放在外面解决了这个问题的帖子 UpdatePanel 的,但从图形上来说,该按钮将不会出现在 正确的地点。它需要是 ID 为 btnDiv 的 DIV。
那么...我如何让下面的按钮触发?
<asp:Button ID="BtnAddStatus" CssClass="small button Detail" Text="Share" runat="server" />
ASPX 代码如下:
<asp:Content ContentPlaceHolderID="ContentCenter" runat="server">
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Always" runat="server">
<ContentTemplate>
<asp:Label ID="lblMessage" runat="server"></asp:Label>
<asp:Repeater ID="repFilter" runat="server"
onitemcommand="RepFilterItemCommand">
<HeaderTemplate>
<div class="UIComposer_Box">
<span class="w">
<asp:TextBox class="input" ID="txtStatusUpdate" TextMode="MultiLine" Columns="60"
name="txtStatusUpdate" Style="overflow: hidden; height: 40px; color: rgb(51, 51, 51);"
runat="server"></asp:TextBox>
</span>
<br clear="all">
<div id="btnDiv" style="padding: 10px 5px; height: 30px;" align="left">
<span style="float: left;"> PHP, Codeigniter, JQuery, AJAX Programming +

<asp:Button ID="BtnAddStatus" CssClass="small button Detail" Text="Share" runat="server" />
</div>
</div>
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="Label1" Text='<%# ((Alert)Container.DataItem).Message %>' runat="server"></asp:Label>
</ItemTemplate>
<FooterTemplate>
<br class="clear" />
</FooterTemplate>
</asp:Repeater>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Content>
AND MY PAGE LOAD 代码:
protected void Page_Load(object sender, EventArgs e)
{
_presenter = new DefaultPresenter();
_presenter.Init(this);
}
AND BtnStatusClick 方法:
protected void BtnAddStatusClick(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
var su = new StatusUpdate
{
CreateDate = DateTime.Now,
AccountId = _userSession.CurrentUser.AccountId,
Status = "" //txtStatusUpdate.Text
};
_statusRepository.SaveStatusUpdate(su);
_alertService.AddStatusUpdateAlert(su);
_presenter = new DefaultPresenter();
_presenter.Init(this);
}
}
再次感谢。

I am trying to get a button inside a repeater inside an updatepanel to fire.
I't won't. I have tried adding a trigger outside the ContentTemplate and inside
the UpdatePanel to no avail:
<Triggers>
<asp:AsyncPostBackTrigger ControlID="BtnAddStatus" EventName="Click" />
</Triggers>
In fact, the AsyncPostBackTrigger's ControlID is always red and tells me "Cannot Resolve Symbol". This seems to be the case no matter where on the page I put the trigger.
I have read posts that have solved this problem by putting the button outside
of the UpdatePanel but then, graphically speaking, the button will not be in the
correct spot. It needs to be DIV with the ID of btnDiv.
So... how do I get the below button to fire?
<asp:Button ID="BtnAddStatus" CssClass="small button Detail" Text="Share" runat="server" />
ASPX code as follows:
<asp:Content ContentPlaceHolderID="ContentCenter" runat="server">
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Always" runat="server">
<ContentTemplate>
<asp:Label ID="lblMessage" runat="server"></asp:Label>
<asp:Repeater ID="repFilter" runat="server"
onitemcommand="RepFilterItemCommand">
<HeaderTemplate>
<div class="UIComposer_Box">
<span class="w">
<asp:TextBox class="input" ID="txtStatusUpdate" TextMode="MultiLine" Columns="60"
name="txtStatusUpdate" Style="overflow: hidden; height: 40px; color: rgb(51, 51, 51);"
runat="server"></asp:TextBox>
</span>
<br clear="all">
<div id="btnDiv" style="padding: 10px 5px; height: 30px;" align="left">
<span style="float: left;"> PHP, Codeigniter, JQuery, AJAX Programming +
Tutorials ( <a href="http://www.x.info" target="_blank" style="color: rgb(236, 9, 43);">
www.x.info</a> ) </span>
<asp:Button ID="BtnAddStatus" CssClass="small button Detail" Text="Share" runat="server" />
</div>
</div>
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="Label1" Text='<%# ((Alert)Container.DataItem).Message %>' runat="server"></asp:Label>
</ItemTemplate>
<FooterTemplate>
<br class="clear" />
</FooterTemplate>
</asp:Repeater>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Content>
AND MY PAGE LOAD CODE:
protected void Page_Load(object sender, EventArgs e)
{
_presenter = new DefaultPresenter();
_presenter.Init(this);
}
AND THE BtnStatusClick Method:
protected void BtnAddStatusClick(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
var su = new StatusUpdate
{
CreateDate = DateTime.Now,
AccountId = _userSession.CurrentUser.AccountId,
Status = "" //txtStatusUpdate.Text
};
_statusRepository.SaveStatusUpdate(su);
_alertService.AddStatusUpdateAlert(su);
_presenter = new DefaultPresenter();
_presenter.Init(this);
}
}
Thanks again.

您是否尝试过在按钮中设置单击事件而不是从后面的代码处理它?
Have you tried setting the click event in the button instead of handling it from the code behind?
