redesign form region file each time with .net custom control
 

hello

I've placed .Net custom control on form region adjoined to message
form.The region is displayed but whenever I make any change to UI ,I
need to design the form region file each time.Previously the custom
control was in vb6 & I was not required to redesign the form region
file each time I made some change to UI of custom control.Is there any
way to avoid this redesigning?

I've VS 2005 VSTO addin
Thanks
