.net - Setting ReadOnly Property In PropertyGrid Sets All Properties Readonly?

Jun 12, 2012

I 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.

.net - Listing Properties / Checking If A Property Is ReadOnly

Nov 26, 2009

I'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?

.net - If An Interface Defines A ReadOnly Property, How Can An Implementer Provide The Setter To This Property

Jun 10, 2011

Is 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

Name A Property 'ReadOnly'?

Oct 20, 2009

I 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.

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

Creating Instances Of A Class That Has Several Readonly Properties?

May 24, 2011

What is an elegant way to create and initialise instances of a class that has several readonly properties? Passing all values in a constructor would not be very convenient.

The purpose is that instances are immutable after initialisation. However if the constructor is not used for initialising all the property values, then how can the readonly properties be changed from another class?

Copying A Set Of Private Variables Into Corresponding Public ReadOnly Properties?

Oct 18, 2011

I have a bunch of private variables I've typed out and I want to put all of my corresponding Public ReadOnly Properties in a bunch below them.Is there some way of copying ten lines of

Private _myVar As String

and pasting in ten sets of

Public Readonly Property MyVar As String
Get
Return _myVar[code]....

I'm currently copying the whole bunch of variable declarations, Find+Replacing Private _ into Public ReadOnly Property then going line-by-line expanding the definitions and writing return statements.how to avoid all this nonsense in the future, as I'm developing on a virtual terminal server, and the input lag on my little copy/paste/type operations on the code is driving me up the wall.

Visual Studio 2008 - ReadOnly Properties/Functions In .Net?

Sep 28, 2010

I'm working on rewriting something in VB that was previously in C# and while I was doing so, I came across a "dilemna." I can have a ReadOnly Property:

Public ReadOnly Property MaximumIndenture()
Get
Try
'If the connection is closed, open it.'

They both essentially do the same thing, but I'm not sure which would be more accepted in the community.

It seems that in the following example, TestProperty() and TestDouble() are functionally equivalent. Is the case? I usually use Property/Get when I have a single line "Return Variable_" type of "function", and Function when I have a more involved thing going on. Is that reasonable?

Optional Readonly Property In Interface

Aug 25, 2009

I 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?

The error message Implementing property must have matching 'ReadOnly' or 'WriteOnly' specifiers is pretty self-explanatory, so I do know what's wrong here. It's also not a big issue, because it's quite easy to work around this limitiation. I'm curious, though: Does anyone know why the VB designers decided to treat this case differently than in C#?
