My current aspx.designer.cs is not working properly, does anybody have any idea about regenerating aspx.designer.cs in solution explorer.
回答1:
Found here:
Within the Visual Studio:
1) Remove your aspx.designer.cs file 2) Right click on your aspx file and select "Convert to Web Application" or for VS2017 click on your aspx file and then from Project menu, click "Convert to Web Application"This should add the aspx.designer.cs back and up to date.
If you get an error saying:
"Generation of designer file failed: The method or operation is not implemented."
Try close Visual Studio and then reopen your project and do step number two again
And here:
Missing or corrupted designer file causes Visual studio (VS) to fail the build. This is because without designer file VS is unable to find the declarations of controls. Also most of the time controls are not added to designer.cs giving build errors.
To fix this issue, Below is the simplest solution I know:
- Delete your designer file if it is corrupted else start from step2.
- Go to your aspx markup (source) page and find below line of code.
<%@ Page Language="C#" AutoEventWireup="false" CodeFile="SamplePage.aspx.cs" Inherits=" SamplePageClass" %>- Now change CodeFile tag to CodeBehind.
- Save the file.
- Rebuild your project (This will create designer file for your page)
- Revert your change (Step3).
