Indicating that attribute must be required on server control

[Craftor]

Hi all

I am currently in the process of creating a server control for inclusion on a form. One of the attributes should be required. Is there any way to force this when I set up the attributes? My code for the attribute currently looks like:

[Category("Custom")]
public string ModuleID
{
	get{return _moduleID;}
	set{_moduleID= value;}
}

Thanks as always

Not sure about making it required, but could you specify a default value?

Hi dragonwell

Gave it a default value - that seems to be working fine for the moment. Ideally what I would like to do is have something similar happen to when you remove an element's ID attribute in the Properties window and it pops up a message box to say Component name cannot be empty.

Any ideas - please let me know

Thanks as always

Could you just simply check from within the property to see what the user has entered? If they have entered an incorrect value, set it to your default value?

I was reading the following MSDN article which doesn't exactly describe how to make it required but does give you a bit of information on the default value attribute:

http://msdn.microsoft.com/library/d...onentModelDefaultValueAttributeClassTopic.asp

Actually, just out of interest, I wonder what would happen if you used messagebox.show from within the property in the MSDN example?

ca8msm - I like your idea - I think that is the way I am going to go.
