Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
|
GetProperties | When overridden in a derived class, returns an enumeration that contains the properties to translate for the specified type. |
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
HasValueTranslation | Determines whether the specified property should be translated for the specified type. |
|
InvalidateProperty | Raises the PropertyInvalidated event to indicate that the specified property was invalidated. |
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
ToString | Returns a string that represents the current object. (Inherited from Object.) |
|
TranslatePropertyValue | Calls custom logic to translate the specified property for the specified type and instance, and specifies the value to translate. |

Remarks
Normally, when a user changes a property value of an object in the designer, that value is set on the object in the designer. Custom control authors can insert custom logic into this process. The property value is translated from the value that the end user sets, to a new property value provided by the control author. For example, they want the user to be able to set the visible property of a control to false, but the control should still be visible at design time. The visible property is translated to true in the designer. These changes affect the designer only. At run time, the properties appear with the values set by the user.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
