.net - Setting ReadOnly Property In PropertyGrid Sets All Properties Readonly?
Jun 12, 2012I am using a PropertyGrid control to edit my class properties and I am trying to set certain properties read-only depending on other property settings.This is the code of my class:
Imports System.ComponentModel
Imports System.Reflection
Public Class PropertyClass[code].....
This is the code I am using to edit the values:
Dim c As New PropertyClass
PropertyGrid1.SelectedObject = c
The problem is that when I set SomeProperty to True, nothing happens and when I then set it to False again it sets all properties Read-Only.

View 1 Replies.net - If An Interface Defines A ReadOnly Property, How Can An Implementer Provide The Setter To This Property
Jun 10, 2011Is there a way for implementers of an interface where a ReadOnly property is defined to make it a complete Read/Write Property ?
Imagine I define an interface to provide a ReadOnly Property (i.e., just a getter for a given value) :
Interface SomeInterface
'the interface only say that implementers must provide a value for reading
ReadOnly Property PublicProperty As String
End Interface
This means implementers must commit to providing a value. But I would like a given implementer to also allow setting that value. In my head, this would mean providing the Property's setter as part of the implementation, doing something like this :
Public Property PublicProperty As String Implements SomeInterface.PublicProperty
Get
Return _myProperty

Why Cant A Readonly Property Be Overrided With A Read/write Property In .net

C# - ReadOnly Property Or Property With Private Set Should Use?
Jan 26, 2012I Like .NET automatic properties, in C# it so easy to declare readonly property by declaring its set section as private like this:
public String Name{ get; private set; }
But when I tried that in VB.NET I was shocked that it is not supported as mentioned here and I have to write it as follows:
Private _Name as String
Public ReadOnly Property Name as String
Get
[Code].....
What the difference between these declarations in VB.NET, which one is preferred and Why?
Which one will affect compile time, runtime or performance at all?
Name A Property 'ReadOnly'?
Oct 20, 2009I have a user control and I'd like to give it a custom property named ReadOnly. I get "Keyword is not valid as an identifier", as it thinks I'm writing a ReadOnly Property named something.
so really I can call mine 'Read_Only', but I'm just curious if there's an easy way to get the other name in there, since then my control will be similar to the visual controls that have ReadOnly in the designer.

Difference Between A Readonly Property Get() And A Function?

View 3 RepliesOptional Readonly Property In Interface
Aug 25, 2009I am trying to develop a simple interface for allowing quick lists to be generated from classes. Basically, the interface needs to return an ID and a Name. However, some classes have a calculated name property which is read only, others just use a read/write name property. Basically, all I care is that it has a getter, it does not matter if the property has a setter. How can I write this interface to handle either or without throwing compile errors?

.net - Listing Properties / Checking If A Property Is ReadOnly
Nov 26, 2009I'm faced with a couple of problems in VB.net: I have a series of objects, which properties I'm displaying in a grid for the user to edit. My first problem is: how do I get a list of all the properties of an object? Is it even possible? The datagrid control that I'm using accepts string values with the name of the property as parameters, but inserting them manually would be a real problem, because there are a LOT of them. So: is there a way to get a list of strings with the name of each property of an object?
If that's possible, here comes the second question: Now, of course, since users are editing the properties, I'm not interested in showing ReadOnly properties which they cannot edit. Hence my secodn problem: is there a way to check if a property is readonly at runtime?

The error message Implementing property must have matching 'ReadOnly' or 'WriteOnly' specifiers is pretty self-explanatory, so I do know what's wrong here.
