Hello there, 7 Ţurţuri is back with more disturbing questions!!!

I am currently modifying my designer to allow control renaming. But what do you know? I have problems here also !
I've implemented the IExtenderListService and got the (Name) property in my grid. When I rename a component, the new name is verified and I do get a message telling me that the new name is not allowed. That's okay... for now. Because when I rename it corectly, i get an "Object reference not set to an instance of an object" name for my control. Then I try to debug it and see if there are any exception unhandled. None. And when I resume from debug, I get the correct name for the control. :-? A friend told me it maybe because there is a thread sync problem around there. Plausible.

So, designer gurus ^:)^ ! What should I do?

Hi,

What's the error shows when the new name is not allowed?

Best regards,
Ling Wang

Hi, Ling Wang

I do not get an exception that may be caught or anything like that. The (Name) property of the newly renamed control shows the following string, no matter which control I rename : "Object reference not set to an instance of an object." Do you have any hint as to why does this happen?

->Object reference not set to an instance of an object.

This error always happen a object or control has definitionbut you don'tinitialize it.

It cannot be uninitialized. Remember I am only renaming it, not removing it and adding a new control with the new name.
