Hello.
I want to set to any type the value, by sending its string only.
How can I do that ?

I.e
BorderStyle = "None"
(I have "None" value as a string)

Thanks :)

I need to not create type editor for each type.
The specific type is unknown, and I need a generic solution for any type.

Thanks :)

I guess you will ask...

To create a TypeConverter:
1. Get the type of the property (PropertyInfo.PropertyType)
2. Check the attributes of the type retrived in step 1.
3. If there is a System.ComponentModel.TypeConverterAttribute, get it's 'ConverterTypeName'
property.
4. Pass the name from step 3 to System.Type.GetType
5. Create an instance of the type from step 4 by passing it to Activator.CreateInstance
6. Cast the object from step 5 to System.ComponentModel.TypeConverter. (Before, I'd check
if it's really of that type. Just for safety, because I think the constructor of
TypeConverterAttribute doesn't check the passed type.)
7. Read the documentation about the TypeConverter. :-) The ConvertFromString/ConvertToString
methods seem to do the main job.

I've never done all that. But that's how I'd do it.

Man, I'm really patient. Very patient. Usually. But you guy seem
to be not willing first to learn the things you need for your task.
I don't believe you have already studied the topics in the link I
gave you.

The first line in the first sub topic says:

"You can edit your property in place as a string. This requires a
TypeConverter for your custom type. For more information, see
How to: Implement a Type Converter."

Isn't it what you are looking for?

You ask for a general solution. There is not solution that is more
general than described in the documentation. The TypeConverterAttribute
is the most general solution I know of. I'm not talking about UI type
editors here.
