Hiding a Property from Property Grid at Runtime

The attributes of a property can be set as read-only in runtime for property grid using a PropertyDescriptor. User can set it either in a member function of a class or in a get{} set{} section of property. The following code sets the readonly attribute of a property “DataType” to true. In the same way, the user can set it as false.

Hide   Copy Code

PropertyDescriptor descriptor = 
    TypeDescriptor.GetProperties(this.GetType())["DataType"];
ReadOnlyAttribute attrib = 
    (ReadOnlyAttribute)descriptor.Attributes[typeof(ReadOnlyAttribute)];
FieldInfo isReadOnly = 
 attrib.GetType().GetField("isReadOnly", BindingFlags.NonPublic| BindingFlags.Instance); 
isReadOnly.SetValue(attrib, true);

Note: ReadOnlyAttribute of all the properties must be set before, like [ReadOnlyAttribute(true)], while writing the class. Otherwise, the above code will set all the property’s attributes to true.

In the same way, the Browsable attribute of any property can be set at runtime using PropertyDescriptor. Here is the code:

Hide   Copy Code

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);

The point to remember in both the cases is that all the attributes must be set for all properties, otherwise it will refresh all the properties of the class.
