我为我的应用程序使用母版页概念。我在aspx页面中有以下代码
我有一个gridview和一个文本框，我从codebehind绑定这个gridview（基于db值，我将在客户端有很多行）。每当我在文本框中输入一个值时，整个页面都会加载，并且ajax不起作用。这段代码中的错误是什么？我已经在母版页中添加了scriptmanager。它总是加载整个页面。由于它是母版页概念，下面的代码在contentplaceholder
中的 的

答案 0 :(得分：0)
我希望解决方案是删除sudo mkdir -p /usr/local/Frameworks
sudo chown -R $(whoami) /usr/local/*
brew link python@2
然后我想到的第一个解决方案是：
1-将UpdateMode更改为UpdateMode，然后将Conditional设置为ChildrenAsTriggers，这样您就可以拥有以下内容：
false 2-第二个：如果第一个不起作用，则删除更新面板的<asp:UpdatePanel ID="updPnl" UpdateMode="Conditional" ChildrenAsTriggers="false" runat="server">
<ContentTemplate>
......
<asp:TextBox ID="txtQuantity" AutoPostBack="true" OnTextChanged="txtQuantity_TextChanged" class="form-control" runat="server" Text='<%# Bind("QUANTITY") %>' Style="width: 80px" MaxLength="8"></asp:TextBox>
........
......
并为该文本框定义一个触发器，使代码类似
UpdateMode希望这些能帮到你。
