I have run the form, but the toolbox is disabled when I returned to source code view.

What did I forget?

    Hi @John ,

    Does the toolbox display the following content when switching to the source code page? This is a normal phenomenon, because the source code page does not allow dragging of controls, so the toolbox is disabled. WinForm pages can drag and drop controls, so the toolbox is available. You could refer to the document, which states "Toolbox appears in conjunction with designer views ".
