为什么在C#net中单击信用/借记单选按钮时不显示文本框？

c# asp.net visual-studio-2017

为什么在C#net中单击信用/借记单选按钮时不显示文本框？,c#,asp.net,visual-studio-2017,C#,Asp.net,Visual Studio 2017,这是我的aspx.cs文件 protected void RadioButton1_CheckedChanged(object sender, EventArgs e) { TextBox2.Visible = true; } protected void Button1_Click(object sender, EventArgs e) { TextBox1.ReadOnly = false; } protected void RadioButton2_CheckedCha

这是我的aspx.cs文件

protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
{
    TextBox2.Visible = true;
}

protected void Button1_Click(object sender, EventArgs e)
{
    TextBox1.ReadOnly = false;
}

protected void RadioButton2_CheckedChanged(object sender, EventArgs e)
{
    TextBox2.Visible = false;
}

为什么选中贷方/借方

单选按钮时文本框不出现？
您必须使用AutoPostBack=“true”
，并且可以使用以下代码。它起作用了
Aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="Stack_Overflow.WebForm1" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
        <asp:RadioButton ID="RadioButton1" AutoPostBack="true" runat="server" Text="Credit" OnCheckedChanged="RadioButton1_CheckedChanged" GroupName="a">

        </asp:RadioButton>
        <asp:RadioButton ID="RadioButton2" AutoPostBack="true" runat="server" Text="Debit" OnCheckedChanged="RadioButton2_CheckedChanged" GroupName="a" />
        <br />
        <asp:Label ID="Label6" runat="server" Text="Label"></asp:Label>
        <br />
        <asp:Label ID="Label7" runat="server" Text="Label"></asp:Label>
        <br />
        <asp:Label ID="Label8" runat="server" Text="Label"></asp:Label>

        <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
        <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
        <asp:TextBox ID="TextBox4" runat="server"></asp:TextBox>

        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    </div>
    </form>

</body>
</html>
