I have a property grid displaying a list, for example of a class Person
[TypeConverter(typeof(ExpandableObjectConverter))]
public class Person
{
public bool ShowHidden { get; set; }
public string Name { get; set; }
//[Browsable(false)]
public string Hidden { get; set; }
public override string ToString()
{
return string.Format("Person({0})", Name);
}
}
The question is how do I control the Browsable()
attribute at runtime such that when ShowHidden = false
the Hidden
line (highlighted yellow below) is omitted.
Thanks.
Here is an example:
PropertyDescriptor descriptor=
TypeDescriptor.GetProperties(this.GetType())["DataType"];
BrowsableAttribute attrib=
(BrowsableAttribute)descriptor.Attributes[typeof(BrowsableAttribute)];
FieldInfo isBrow =
attrib.GetType().GetField("browsable",BindingFlags.NonPublic | BindingFlags.Instance);
isBrow.SetValue(attrib,false);
Just replace DataType
with your property name.
Note, all properties must have the attribute being changed (in this case, Browsable). If one of the properties is missing the attribute, all of the class properties get the new attribute setting.
