Value not valid for 'RowPositon' in Visual Studio when moving a designer control

[IT_Researcher]

In Visual Basic (VS 2017 / 2019 / 2022, including 2017 Express), I keep encountering a strange issue when working with the WinForms designer.

Whenever I move or drag a control (e.g., a TextBox) in the designer, and then start the debugger, Visual Studio shows the following error message box three times before the application runs normally:

InvalidArgument=Value of '-2147483648' is not valid for 'RowPosition'




My question is, why does it appear. And how can it be fixed?


What I’ve already tried (no effect):

Build ? Clean Solution, then Rebuild Solution
Commented out all lines that call set_RowPosition in designer code
Verified that none of my code runs before the error appears

More information:

Happens across multiple Visual Studio versions (2022, 2019, 2017 Express)
The error is from Visual Studio, not from my application
Windows Forms project targeting .NET Framework 4.0

That is odd. Is this happening at compilation or at runtime (that then crashes)?
