How to loop through all Properties

[cassb]

Can you tell me what the internal structure is so I can write a For loop to go through all my public properties that are defined in the Properties region?

Thanks!

cass,

Unfortunately there is no way to do this via supported methods as these are separate variables, not arrays or lists.

You may find this useful however : http://en.wikipedia.org/wiki/Reflect...er_programming)

OK, thanks Adam!

I have a related question then... you'll notice that if you click on a parameter value and change it to something different and then hit Tab or Return, then the get/set accessors are called. However, if you click on a parameter value and change it to the same value it already was, then the get/set is not called. I have some code in the 'set' that I want called regardless of whether you changed the parameter value or not, as long as you clicked on it. Is this a NT limitation or a C# feature?

Thanks!
Bryan

Edit: Wait... maybe the "get" is called when you first access the parameter field? I could put my code into that instead of "set"... I'll try that first.

cassb,

This would be a C# feature unfortunately. Get/Set are both parts of C#.

OK -- yes a little experimentation and I see that Get is called every time the parameter field is displayed, even if you are just scrolling the parameter list up and down. It gets called a zillion times! So this may not do it for me. I need to have something called when the user exits that field, regardless of whether the value changed or not. The Set accessor is not the answer, apparently.

Is there a FieldExit event or something I can use to do this?

Here is some more information on get and set : http://msdn.microsoft.com/en-us/library/w86s7x04.aspx

Yes, thank you I've been reading that already. But I think I need some construct that I don't yet know in c# in order to get the setter to be called regardless of whether the value changed or not. Something like [Bindable] maybe... I'm not sure. I'll have to see if I can find some c# code examples out there that do this.

Thanks!

You can do this (loop through your properties) by implementing the ICustomTypeDescriptor interface and then using GetProperties().

Thanks, Zeos! I ended up just typing in all my properties one by one though, instead of making a neat loop. Oh well... it works at least. :-)

Glad it worked out for you.
