我在asp.Net中有一个网站，其中包含一个带有asp按钮的弹出窗口。我的问题是，按钮点击事件不会弹出。当imagebutton1点击时，我的弹出窗口打开。我也在使用计时器刻度。 我完全陷入了困境。 我的代码如下： -按钮点击事件没有在弹出窗口中触发
<div>
<script type="text/javascript">
function buttonClicked() {
var textBox = $get("TextBox1");
textBox.scrollTop = textBox.scrollHeight;
}
</script>
<asp:UpdatePanel ID="ChatUpdatePanel" runat="server" UpdateMode="Always">
<ContentTemplate>
<div id="second1" runat="server" style="width:570px;height:100px;background-color:#e5f7f6;border:solid 2px #35b8b3;position:absolute;margin-left:5px;margin-top:5px;border-radius:5px;">
<span style="color:Blue;font-weight:bold;margin-left:180px;margin-top:20px;">Ringing Expert...Please Wait</span>
</div>
<asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine" ReadOnly="True"
width="100%" style="resize:none;" Height="200px" AutoPostBack="False"
MaintainScrollPositionOnPostBack="True" >
</asp:TextBox>
</ContentTemplate>
<Triggers>
<%--<asp:AsyncPostBackTrigger ControlID="SendButton" EventName="Click" />--%>
<asp:AsyncPostBackTrigger ControlID="ChatTextTimer" EventName="Tick" />
</Triggers>
</asp:UpdatePanel>
<asp:Timer runat="server" ID="ChatTextTimer" Interval="100"
ontick="ChatTextTimer_Tick" />
<asp:TextBox ID="NewMessageTextBox" DefaultButton="SendButton" Columns="50" runat="server" Height="25px"
Width="80%" style="margin-left: 0px;margin-top:5px;" Font-Size="Medium" />
<asp:Button ID="SendButton" Text="Send" runat="server" OnClick="SendButton_Click" Height="25px" style="margin-left:50px;" />
<a href="#" style="text-decoration:line;">Report Abuse</a>
<br />
<div style="width:100%;margin-top:10px;">
<asp:Image ID="Image3" runat="server" Width="70px" Height="50px" />
<div style="width:80%;height:50px;float:right;margin-right:30px;">
Status:<br />
<span style="color:Blue;font-weight:bold;font-size:large;">Not Charging</span>
<span style="float:right;font-weight:bold;font-size:medium;color:Blue;">$ <asp:Label ID="Label12" runat="server" style="font-weight:bold;font-size:medium;color:Blue;" Text="Label"></asp:Label>/Minute</span>
</div>
</div>
和我的后端代码如下： - 我已经解决了它

哪个按钮的事件不会触发？你引用你的javascript函数'buttonClicked'没有被调用，或者你的意思是asp.net代码隐藏'button_Click'事件？ –
按钮ID是SendButton，并且此按钮必须触发后端代码中的事件。这实际上是服务器端代码 – yash
