Error during Generation of [Form].Developer.vb code in BeginInit / EndInit rows for DataGridView and NumericUpDown Controls

Hello, Sorry if this is a noob question...

Other VB.NET Forms with DataGridView and NumericUpDown controls in this Project work fine. The generated lines in '.Developer.vb' looks like:

CType(dgvwStructLibrary, ComponentModel.ISupportInitialize).BeginInit()
CType(numspnStructLaborCode, ComponentModel.ISupportInitialize).BeginInit()

Form that error occurs looks like:

(CType(Me.dgvwStructLibrary, Global.System.ComponentModel.ISupportInitialize)).BeginInit()
(CType(Me.numspnStructLaborCode, Global.System.ComponentModel.ISupportInitialize)).BeginInit()

Differences:

  • CType( --> (CType(Me.
  • ComponentModel.ISupportInitialize). --> Global.System.ComponentModel.ISupportInitialize)).

Manually updating (.Developer.vb file) removes error from Error List:

  • (CType( --> CType(
  • .ISupportInitialize)). --> .ISupportInitialize).

But Error will return with:

  • Almost any modification in visual GUI Designer.
  • Every few changes in Form Code. After correcting and Rebuilding, Form does behave correctly for a few minutes... then the error comes back.

Thank you,

Ken

    Hi @kb_qiw ,

    When you make a modification in the designer view, it produces new code that overwrites the original code in the designer .vb.

    If other forms don't have this problem, maybe you can try recreating this form to see if the same problem persists.

    Or try updating your Visual Studio to the latest version.

    Best Regards.
