OK, for everyone having a problem with subclassing a control & killing VS when you drop it on a form, we've fixed the problem.  It only happened on controls that were ILocalizable because the LocalizationDesigner got itself into a loop while trying to get the designer actions for the control.  Took us a while to figure out where it was failing, but it's working now, so you'll need the latest version of the Extensiblity DLL in your GAC.  I've also included the 4 Core DLLs because they are versioned with this extensibility DLL.

You need to add a few "using" statements to the top of your subclassed control:

using MicroFour.StrataFrame.UI;
using MicroFour.StrataFrame.UI.Windows.Forms;
using System.Drawing;
using System.Windows.Forms;

BTW, I am using C#, therefore I cant copy the source code from SF and do modification.

Hi,

I tried to create an derived label (mylabel) based on system.windows.ui.forms. Then, I created another derived control based on the mylabel (mymylabel). It works fine when I drop mymylabel to form.



Therefore, I am sure I do it the right way. Just that, I may miss out something which is necessary in order to subclass SF Control. Anyone can help here?



Your helps are really appreciated.



Thank you

Sorry, I really can't make it after trying and trying.



I got error if I copy code from linklabel. I already added the all necessary references by refer to MicrosFour Strataframe UI.



Do you mind to create a label subclass sample and direction to do this? Sorry for any inconvinience.

It might be a type editor problem.  It might be easiest if you take the source code for one of the SF controls... say LinkLabel and copy that into your own control and modify it.  VS isn't always great about informing you of problems at design-time... sometimes it just dies.

Hi,

I can drop Strataframe control to form without any problem, but not my derived control

Can you drop a LinkLabel from the StrataFrame Controls & Components tab onto a form, or does it kill VS as well?

Hi,

May I know anything wrong for code below?

I am facing problem VS.NET will exit automatically if I drop the control (derived from SF control) on form. However, if I changed to derived from standard control (System.WIndows.Forms) then is ok.



Any ideas?
