Conclusion. This attribute has three properties: Let's consider the property PropA from our sample class. here PropC gets an ID 1 and CatA gets in ID 3 as well. So each field becomes an standard-value, thus you can use the properties of the StandardValueAttribute to show/hide/enable/disable any member of the enumeration. DataGridView provides a visual interface to data. You can use dynamic properties to change some property values without recompiling the application.

I see the details using vb.net programme like tag, subject, comment, etc. This allows you to override resource information of this enumeration type that is defined in another library that you do not have access to in the source code. Create an instance of it and let the PropertyGrid select it instead of the original object. But some features may need some explanation. Let's say I have a custom class with a datarow property and an enum (ContactTypes), and I pass a datarow (_DR) into my constructor, which in turn generates various properties on the fly from the columns.
