Button1_Click is not a member of ASP default2_aspx<\/strong><\/h4>\n\n\n\n

The error message “Button1_Click is not a member of ASP.default2_aspx” typically occurs when there is a mismatch between the code-behind file and the ASPX file in an ASP.NET application.<\/p>\n\n\n\n

Here’s an example:<\/p>\n\n\n\n

public partial class Default2 : System.Web.UI.Page<\/p>\n\n\n\n

{<\/p>\n\n\n\n

    protected void Page_Load(object sender, EventArgs e)<\/p>\n\n\n\n

    {<\/p>\n\n\n\n

    }<\/p>\n\n\n\n

    protected void Button1_Click(object sender, EventArgs e)<\/p>\n\n\n\n

    {<\/p>\n\n\n\n

        \/\/ Do something<\/p>\n\n\n\n

    }<\/p>\n\n\n\n

}<\/p>\n\n\n\n

In this example, we have a Default2.aspx.cs file that contains a Button1_Click event handler method. However, if the corresponding ASPX file (Default2.aspx) does not have a reference to this event handler method, we can get the “Button1_Click is not a member of ASP.default2_aspx” error.<\/p>\n\n\n\n

To fix this, you need to ensure that the ASPX file has the correct CodeBehind or CodeFile attribute that references the correct code-behind file. Here’s an example:<\/p>\n\n\n\n

<%@ Page Language=”C#” CodeBehind=”Default2.aspx.cs” Inherits=”MyProject.Default2″ %><\/p>\n\n\n\n

<!DOCTYPE html><\/p>\n\n\n\n

<html><\/p>\n\n\n\n

<head><\/p>\n\n\n\n

    <title>Default2<\/title><\/p>\n\n\n\n

<\/head><\/p>\n\n\n\n

<body><\/p>\n\n\n\n

    <form runat=”server”><\/p>\n\n\n\n

        <div><\/p>\n\n\n\n

            <asp:Button ID=”Button1″ runat=”server” Text=”Click me” OnClick=”Button1_Click” \/><\/p>\n\n\n\n

        <\/div><\/p>\n\n\n\n

    <\/form><\/p>\n\n\n\n

<\/body><\/p>\n\n\n\n

<\/html><\/p>\n\n\n\n

In this example, we have added the CodeBehind attribute to the @Page directive, which references the correct code-behind file (Default2.aspx.cs). We have also added an OnClick attribute to the Button control, which references the Button1_Click event handler method. Once you have made these changes, you should be able to build and run your application without getting the “Button1_Click is not a member of ASP.default2_aspx” error.<\/p>\n\n\n\n
