Question

I have two fields that are of the same type in my property-grid. However, one is read-only, the other is editable.

Both of these fields are of a custom type, and thus have a custom UITypeEditor, which puts the elipsis ([…]) button on the field.

[      CategoryAttribute('5 - Wind'),      DisplayName('Factored Area'),      Description('The factored area for the segment.'),      EditorAttribute(typeof(umConversionTypeEditor), typeof(UITypeEditor)),      TypeConverter(typeof(umConversionTypeConverter)),      ReadOnly(true) ] public FactoredAreaClass FactoredArea { ... }  [      CategoryAttribute('5 - Wind'),      DisplayName('Factored Area Modifier'),      Description('The factored area modifier.'),      EditorAttribute(typeof(umConversionTypeEditor), typeof(UITypeEditor)),      TypeConverter(typeof(umConversionTypeConverter)) ] public FactoredAreaClass FactoredAreaMod { ... } 

In this example, FactoredAreaMod is available to be edited, but BOTH have the elipsis, which will cause great confusion with the users. Any way to turn that off??

Answer 1

Use the ReadOnly attribute. This marks it as design-time read-only while keeping it read/write for runtime use.

Also, you should either apply the Editor attribute to the type rather than the properties. There’s no gain in applying it to a property if you don’t want that property to be editable.
