本文介绍了更新面板不会更新多次的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在更新面板中使用表格。每行都有文本框和图像按钮。

单击图像按钮，将出现带有文本框和图像按钮的新行。



我第一次点击图像按钮，我得到了一个带有文本框和图像的新行。

但它不是第二次工作，但是事件在代码后面触发。



我的aspx代码：

< asp：UpdatePanel ID =   UpdSystem runat =   server UpdateMode =  条件  >  
< ContentTemplate> 
< div style =   max-height：150px; overflow：auto; width：100％;  >

请帮忙。这非常紧迫。在此先感谢

解决方案

它的工作原理。我删除了未使用过的java脚本。 ：）

I am using table inside update panel. Each row has textbox and image button.
On clicking on the image button, new row will appear with textbox and image button.

When I click the image button for first time, I getting a new row with Textbox and image.
But it's not working for second time, but event is triggering in code behind.

My aspx code:

<asp:UpdatePanel ID="UpdSystem" runat="server" UpdateMode="Conditional" >
            <ContentTemplate>
                <div style="max-height: 150px; overflow: auto; width: 100%;">
                    <asp:Table ID="tblSystem" runat="server" Height="25px">
                        <asp:TableRow>
                            <asp:TableCell>
                                <asp:TextBox ID="txtSystem1" runat="server" CssClass="input-page"></asp:TextBox>
                            </asp:TableCell>
                            <asp:TableCell>
                                <asp:ImageButton ID="imgSystem" runat="server" AlternateText="System" ImageUrl="~/Images/plus1.png"
                                    OnClick="CreateTextBox" />
                            </asp:TableCell>
                        </asp:TableRow>
