Daves fix worked for me.

As a bit of background I was in the designer and all I did was resize a user control (honestly!) and I suddenly got the referenced error message

Looking in the corresponding xxxxxx.designer.cs file I saw the line

MyForm.Controls.AddChildIndex(control,0) (which I didnt understand!)

replacing that line with

MyForm.Controls.Add(control)

and rebuilding fixed it. (I know you not supposed to edit this file, but it worked)

Solution 2

You didn't add the newly created control to the Controls collection of a Form or some other container control like a Panel.

MyForm.Controls.Add(flaRandH)
