Custom DataGridViewColumn Properties?
Jun 21, 2010
I created a custom datagridview column for a progressbar and included customizable color properties but I can't get them to work right. After compiling, the properties show up correctly in the Edit Columns popup editor, but changing the values has no effectThe designer generated code shows the original values and manually changing them there has the desired effect(I know you're not supposed to, just testing). Here is the code for the column even though I don't think the issue is stemming from any coding errors there.
Imports System.Drawing
Imports System.ComponentModel
Imports System.Drawing.Drawing2D

What I've done is create a User Control Library (Project) and I've added a single User Control to that project. The control contains a single FlowLayoutPanel, and I created a Property on the control itself to pass the FlowDirection from the Control to its FlowLayoutPanel child.
Build, reference, component appears in the Toolbox and everything works fine, but the property on the control does not appear in the Properties window when I go to edit it at design time.

following code from c# to visual basic, and I'm coming up with the following error: 'Public Event ItemCheck(sender As Object, e As System.Windows.Forms.ItemCheckEventArgs)' as an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.

I've populated a PropertyGrid with a custom class. How do you create and display a sub property similar to Size (Height, Width) which has two values or Point(X,Y)? For example, the class is Test and the property is Item as string. I want to expand Item to have two sub properties, A and B.

In our IDE, for example, Visual Studio, if we display the properties of a System.Windows.Forms.Button control, we see some properties that expose anoter set of properties. For example: FlatAppearance, Font, Location, Margin, etcetera.I would like to do something similar in a custom control.I know the code behind is wrong, but here is an example of what I´m trying to do:
Public Class StateOfMyCustomControl
Public Enum EnumVisibility
Visible
[code]....
In my IDE, in the properties window of my custom control, I would like to see my property State, with the possibility of display it to set the properties Visibility and EventManagement.

I'm moving my first steps in the VB.NET world (I come from VB6) and I'm stuck with the creation of a particular class.
Let's say we have a bus that always has 101 places. I'm trying to create a class containing the map of the bus, along with methods to graphically represent it.
My "Bus" class will have a couple of properties ("BusColor", "BusModel") related to the whole bus. Then it should have a property called "Places" whose type is a custom class thet represents every single place, along with, for example, the passenger name or the place number. This property should of course be an array.
This is my code so far (simplified):
Public Class BusMap
Private Const MAX_PLACES As Integer = 101
Private _BusModel As String = ""
[Code]....
but I wonder if there is a more standard way of doing this.
My second question is: how can I modify my class to be able to iterate its Places property with the "for each" statement? A quick search on the web showed up that I should implement the IEnumerable interface, but I'm still not enough confident with the concept of Interfaces.

Lets say i'm making a new dialog. I don't want to expose the properties of the form to code elsewhere, only specific ones I define. I tried making the form Protected (including the Designer generated code) and putting it in another class, but then I can't figure out how to access the form from my code. Am I going about this completely the wrong way, or what?

I have built a Custom Control Class that makes it much easier to build a side bar element in my html.
The problem I am running into is that when I set the "Text" property, the last time I set it gets used for every instance of the control on my page. This is my first time doing this, so I'm assuming I'm missing something basic.

Is it possible to make a form that can set the properties on a custom control in the designer? What I mean is I want to know if it is possible to show a dialog that allows you to set the settings for a certain property like if you were adding items to a listbox.

I'm working on a project where I need to information on all the monitors connected to a computer and then write a configuration file based on that. I can already get the screen information by creating a new instance of screen and reading the information such as index, bounds and everything else.I'm trying to create a virtual screen object to hold the information from the screen so I can work with it, or add other properties to it.[code]This all works perfectly how I want it to. Except I would like to do one more thing. How can I make it so that instead of getting Virtual_Screen.Top, I could get Virtual_Screen.Bounds.Top? That way I could create other properties such as Virtual_Screen.Border.Top..I have no idea how to code, or what that would be called. It's hard to search for something you don't know the name of.

I am trying to learn how to create Windows Forms custom controls in VB.Net by creating a .Net version of an old control I created in VB6. On this control, I have a UserControl with a Label (lblCaption), and several of the properties I add to the control should be passed to the label.This is the code I tried for the ForeColor property:
Code:
Protected mcolForeColor As Color = Color.FromKnownColor(KnownColor.ButtonHighlight)
Public Overrides Property ForeColor() As Color
Get
[code]....
When I change the ForeColor on the control in my test project, lblCaption does change to the color I selected; however, when I run the application, the label changes back to the default (button highlight) color, and the value of the property is also reverted back when I return to the form designer.What would be the proper way to implement the ForeColor property on a custom control?

This is similar to my last post but with a different purpose.I have built a custom control, but when I set the properties for it... ALL instances of that control on my page grab the exact same property. I need to be able to set the property to "abc" for one instance of the control on my page, and then set the exact same proprty to "xyz" for a different instance of the control on the same page.

How do I get at and invoke the properties dialog supplied by the manufactured? I have search this many times and found that most of the posts contain solutions that the original poster claims don't work The standard PrintProperties class does not handle a lot of printers who have specifictsks, eg a printer designed to pint on the face odf CD/DVD. I have found examples of how do this in VB6, but every examply I find for the versions of VB Basic after thet have comments that the solution provided did not persist the user chnges. Bow, come on, there has to be a way of displaying and persisting the user choises the dialog bog provided by the printer manufacturer!Terry

I'm trying to build an app that will read custom properties set in an accdb file. Basically, I'm trying to build a Front End updater (Yes I know there are others already built, but they don't work the way I want). The Custom properties are initially set manually by pressing the Office button, going to Manage, then Database Properties and selecting the Custom tab.
I've got most of the code set up, but my sticking point is how to read the custom properties.
Following is the function I use within Access VBA to get the properties, but obviously this is not going to work in VB.Net.
[Code].....
I think I need to replace one or more of the 4 lines after the On Error (yes I know I need to change the Error trapping too). I'm guessing I need to connect to the database file (an accdb, btw) and then go from there to define the container and documents collections.

How would I remove an item from the listbox.. I used the code below to populate using a class with description and value properties.
I cant use listbox.items.indexOf("listitem1") to get index
I cant use listbox.items.remove("listitem1")
If I use listitem.items.removeAt(1) it works of course. How can I get my index in this case?

I have a custom VB.NET control that I created that is working correctly in one program but not in another.The control has one button and one form. The form displays some data based on the settings in the control.
[Code]...
In TestProject1 - the control is working as expected In TestProject2 - the control is not sending any of the settings I set to the form My control works fine when I debug with the UserControl TestContainer.
I am using VB.NET on VS2005. This is all done on the same machine. Why would this work in one project and not another?

I'm fairly experienced with making user controls and have never had this happen to me before. All of my custom properties (gloss opacity, border color, header color 1 and header color 2) are all grayed out in the properties window on the form designer when I try to add my groupbox to a form.
Here's my
