Visual Studio 2022 Winform designer generates code for DataGridView.AutoGenerate = false is incorrect

[MauNguyenVan]

Environment

Microsoft Visual Studio Enterprise 2022 (64-bit) - Current

Project type: Winform .net core 8.0

.NET version

Winform .net core 8.0 but i belive .Net 9.0 has the same the issuse

Did this work in a previous version of Visual Studio and/or previous .NET release?

yes.

Issue description

In Winform Designer, when adding a new DataGridView control, then setting the property ‘DataGridView.AutoGenerate’ becomes ‘false’, the code generated is incorrect:
Instead of generating ‘dataGridView1.AutoGenerate = false’ into the ‘InitializeComponent()’
it declares a new local variant ‘DataGridView1 dataGridView1;’ the adding new variant ‘dataGridView1’ is the same name as the field ‘dataGridView1’ added by the designer before, thus field ‘dataGridView1’ is never initialized => at runtime throw a Null Ex.

I have recorded my screen below the file attachment (I recorded on another computer, but the other VS version (the newest) still met the same issue).

Steps to reproduce

in VS designer

• Add a datagridview in form.
• Change the property ``GenerateMemberof datagridview fromtrue` to `false`
• Check the code generated for the datagridview in method InitializeComponent()

IncorrectDataGridView.AutoGenerate1.mp4

Thanks @John-Qiao for confirming. @MauNguyenVan we don't have a specific timeline in mind for this issue. We will update this when we have addressed it and let you know when you can expect a fix in VS.
