Hide and set default values, confused?

[Martin]

I would like to hide default values for CLR types without making them nullable.

I have properties like Top, Left and the default value for int is 0, but I don't want to show zero, just values set by the user or by me in code.

Hi,

Based on the previous communications with you , I guess that you are using the PropertySets feature. May, I ask you whether am I right? Basically, RadPropertyGrid relies exclusively on bindings and they will automatically retrieve a property's value, which is the default one if it is not initialized with a new value, so such a customization won't be easy to implement. May, I ask you for some more extensive information on your scenario, so that we could think in its context.

All the best,

I just think that default values are the same a not providing any values.

It's would just be nice to have a flag "HideDefaultClrValues" on the property grid.

Hello,

 Unfortunately, supporting such a feature natively won't be compatible with our current architecture. However, I have thought of an easy modification. You can subscribe to RadPropertyGrid's FieldLoaded event and rebind the respective editors by setting OneWayToSource binding mode. Can you please confirm, whether this approach works for you?

Will it still be possible to update the field? if so I will give it a try

Hello,

 Well, OneWayToSource binding will propagate changes only from the View (UI) to the ViewModel and not the other way around. I guess that this is what you really need to achieve your requirements?
