Probably you should start from investigating the IDE with Spy+.:~

ComponentDesigner.OnSetComponentDefaults() executes only when the component is dropped on a windows form. In case of a web form it does not execute. Although the designer object is constructed in both cases. This looks like a framework/IDE bug to me.:confused:

I've been studying Spanish during 1 year, approximately 1 hour daily. Now I speak fluently. The biggest progress I made when started to watch movies in Spanish on dvd. My native is Russian and I obviously speak English too. So good luck with German, watch movies! Igor

You can not see it because you use general type to reference your form. Consider the example:

Form frm1 = new MyFormWithProgressBar();
frm1.Show();
frm1.progressBar1.Value++; // this is error

The correct code is:

MyFormWithProgressBar frm1 = new MyFormWithProgressBar();
frm1.Show();
frm1.progressBar1.Value++; // this will work

Sorry that I have not noticed that mistake in your previous post.

Yes. This is what I meant. Of course this relates to Windows forms, not Web forms.

1. Make the progress bar Public. 2. To the form number 1 give the references to forms 2,3,4... 3. Use the reference to move progress bar. The refenrences can be passed as a constructor parameter or kept as a static array.
