Property Name

[simonbesner]

Hello everyone,

Recently, I did buy a PropertyGrid component. There's only one problem with this component: to add a property, it requires an objet instance (this is ok) AND the property name as a text parameter (this is the problem).

When you build the grid the first time there's no problem with this. You would get something like this:

propertyGrid1.AddProperty(myInstance, "PropertyName1")
propertyGrid1.AddProperty(myInstance, "PropertyName2")
...

However, if you rename or remove a property used by the property grid component, there's no way to be notified at design time.

Could it be possible to create something like this:
propertyGrid1.AddProperty(myInstance, myInstance.Property1.GetPropertyName)

This way, if the property1 is renamed or deleted, VS will list it as an error.

Does someone have a solution?

Regards

Simon

P.S. Someone told me that Lambda Expression could help me... I don't know much about the lambda expression and there's only few example written in VB.

Have a look at Reflection, it's most likely exactly what you're looking for. F.e.:

myInstance.GetType().GetProperties()

Hi Robert,

The main point here is not to get the properties names... it's to get notified by the compiler if a property is deleted or renamed.

This morning I did find a solution using the lambda expression. It's doing exactly what I want (even if I think the lambda expression are realy complex).

I'm still wondering if there's a more simple way to do this.
