VS 2010 Displaying Property Arrays In PropertyGrid Control?
Feb 17, 2011
It seems as if the propertygrid control cannot display property arrays. Is this the case?
When I do this :
Imports System.ComponentModel
Public Class comPicturePirate
Private intAmountImages As Integer
Private strWebURL As String
[Code]...

I am working on a program that will display the number of storms in a specified year. This program uses a text file with years 1990-2010 and the number of storms for each year.
txt file:
Year 2010
6
Year 2009
3
Year 2008
8
Year 2007
15
Year 2006
10 .....
A user selects a year from a ComboBox (cboYear) and the program displays the number of storms using a label object (lblNumberOfStroms) for that year. The user then can click a button (btnDisplayStatistics) and the program will display using a label object, the number of storms for that year. This seems like a simple application but I am having trouble grasping the use of arrays concept.

I am having a problem with objects that have other objects as properties on a property grid. Now when I display the object clsPropsFrame on the property grid, everything shows up as expected, except when I try to edit the x, y, or z of location which is of type clsPropsVec3, it ignores the change. What's strange is that when I type the vector in as a string (like "0, 16, 0"), it changes.
I have the following
'//////////////////Object Component///////////////////////////
<TypeConverter(GetType(ExpandableObjectConverter))> _
Public Class clsPropsVec3
Inherits ExpandableObjectConverter
Private refvec As TV_3DVECTOR
Public Sub New()
[Code] .....
I noticed that when I changed a component of clsPropsVec3, the property change in clsPropsFrame does not get executed. I tried making it fire of an event when a component is changed in clsPropsVec3, with the following additional
Public Property X() As Single
Get
Return refvec.x
End Get
Set(ByVal value As Single)
[Code] .....
But for some reason it ever fires off the ValueChanged event. So how can I make the sub properties of clsPropsVec3 work?

the statement Dim state(49) As String and maintain a list of certain states. The list of states should always be in alphabetical order and occupy consecutive elements of the array. The buttons in the program should give the user the following options: (a) Take the state specified by the user in a text box and insert it into its proper position in the array. If the state is already in the array, so report. (b) Take the state specified by the user in a text box and delete it from the array. If the state is not in the array, so report. (c) Display the states in the array. "
Private Sub states_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have an object with a property that is a collection. When I point the PropertyGrid to the object it displays the ellipses for the collection. When I click it I get the generic collectioneditor. Of course the Add put fails because my collection is strongly typed. I need an example of how to create a collectioneditor that will create my collection's objects.

I'm trying to add a custom DropDown to the PropertyGrid for a control. I am adding the TrackBar control.It works fine, except, I would like to have the values updated in the PropertyGrid as I move the TrackBar. As it is now, it only updates the PropertyGrid when I finish and click off the TrackBar.I know the problem lies in the Type Editor. How can I get it to allow interim values to be processed. Is there some callback function I can use?

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.

Does anyone know of a way have the PropertyGrid control display a NumericUpDown instead of a DropDown box or text box? One of the properties that I need to capture is an integer and I'd like the user to be able to spin up or down to choose a value instead of typing it in.

I've been following this article:and have everything working.Under the Support for Custom Types section, it introduces a collapsable type for the spell check options. The option are added together to produce a string that is displayed in the grid in the Spell Check Options row. Is it possible to get this string directly from the 'AppSettings' class or do I need to add another property and copy the code from the ConvertTo and ConvertFrom functions?

I have been trying to create a custom control based on the ListBox called FileListBox. I followed Microsoft's walkthrough but am having some trouble.
What I want is to add another property to the ListBox called SafeItems which is an ObjectCollection of strings (like the Items property). I will use the Items property to store a collection of Filenames as strings and I would like to store the corresponding SafeFilenames in the SafeItems collection.
This is what I've tried:
FileListBox.Designer.vb
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class FileListBox

I am having difficulty getting some form control property bindings to work correctly. Below is the code I am using-
[Code]...
The ZedGraphControl is just a GraphPane, and the TolSelectBtn is just a button. Problem is, the ZedGraph control binding works properly, but the binding to the button does not (both controls' Visible properties are set to False in the design window). Can a ToolStripMenuItem only handle one data binding? Or is there something else I should be looking for?

this questions has be answered partially, but I can't find any full tutorial for this problem.I created my own user control (an advanced list with columns). Each column has different attributes like width, colour and text.I want to able to add this user control onto a form and select/edit the different attributes of each column. Hence, for each column in my user control (these columns are created beforehand, no columns can be added or removed from it) there should be a property in the property-menu. Each of these column-properties should be expanded (like the normal size-property in most default vb-controls that can be expanded with the little plus to show the width and height individually.What i mean by this, is: In the property-menu there should be attributes like Column1, Column2, Column3. Each of these attributes should be expanded to show the attributes like width or colour.
Currently I have different properties for different values of the same column, like Column1Wodth, Column1Colour, etc, but I want to group this under one value Column1.I think this is quite an easy solution, but forgive me, I spent more than 4 hours on google, but couldn't find a proper solution.

I'm writing a custom control and I want to add a "MessageText" property of type String:
<Browsable(True),
DefaultValue(""),
Category("CustomControls"),
[code]....
The MessageText property is a multiline text, and the user must be able to set the text using the designer. The problem is that the designer doesn't allow to enter a newline directly for a string property.I want the same behaviour as the system TextBox's Text property, where you can click on the down arrow and write lines in the small text-editor that appears:How do I do that?

I am trying to use several Class arrays to hold values that I will cycle through at a later point to perform some calculations. I need to change the array sizes to fit the data as it is entered. I am using one procedure to set the first element of each array and then a separate procedure to pass the additional values as they are entered.
Until my last attempt at changing my code, my StartBalance sub seemed to work, I could step through and see the values assigned to the class arrays in the code block. However, when it moved on to the Transaction sub, it did not recognize that the first set of values were set, the array shows zero values for index 1.
I have gone through several changes trying different ideas from reading blogs and articles, but I guess I am not understanding how these work. I even used the class arrays directly instead of the Property procedures to see if I would get a different result, but I do not.
I believe I must be approaching this incorrectly and though I can find dozens of examples of setting class variables and even a couple on using arrays as class variable, I can not find any that show how to then pass values to those arrays.

Private _tranDate(1) As Date

For example when I click on a CommandButton it will ask me how many textboxes do I require as input. Then it will create that no. of textboxes instantly.

I've got an issue with control arrays from VB6 and converting that code to VB.net. It was suggested to me that the forum has a lot of info on what became of control arrays and each one I've found so far seems to indicate that VB.net has devolved in thatrespect.The solutions I've seen all involve writing segments of code to replace the simple functionality of a group name for a control and a simple index property. Perhaps I've not found the right thread, but it seems that VB.net is woefully lacking in control arrays. In VB6, all I had to do was C&P a control and click, 'Yes,' to create a control array when prompted by VB. The Index was automatically created and incremented for each successivecopy of the control. It was simplicity itself to merely reference the Index for a control group.

In VB6 there is a feature called Control Arrays, where you name controls the same name and provide them an index value. This allows you to set a value by looping through the controls and setting each value. In VB .NET I can't create a control array?
