Addressing A Textual Array Of Controls - Controls("FuelBoxMin_" & IntLoop.ToString & .Text)?
Aug 20, 2011I cannot work out the correct formatting of the above type addressing for a textbox in a (sort of) array of textboxes such as
textbox_1
textbox_2
textbox_3
etc.
The controls are on Tabs but I don't think I need to include the Tab as a container control, just refer directly to the textbox on the form, but I cannot work out how this is done in VB .NET format. In VB6 it was relatively straightforward but VB .NEt seems it is different. Can anyone help me with the correct way to formulate

Creating An Array Of Controls?
May 19, 2009I need to be able to refer to a set of controls on a Windows form using an array, but I'm having a few difficulties.
The Windows form (WForm.vb) contains two textboxes (TextBox1 and TextBox2).
In Module1.vb I have created an array reference to the textboxes thus:
Public wf As New WForm
Public ReadOnly TB() As Control = {wf.TextBox1, wf.TextBox2}
Then, in WForm.vb I have tried to refer to the textboxes via the array:
eg.
TB(0).Text = "Change text to this"
I know that the array is referring to the textboxes, because when I hover the cursor over the line 'TB(0).Text = "Change text to this" ' in debug mode, I get the following:
(0)|{Text = "Change text to this"}
(1)|{Text = ""}
but for some reason, the text in TextBox1 on the form isn't actually being changed!
(There is obviously no problem with change the textbox's text at this point in the code, because I've tried substituting the array reference 'TB(0)' with a direct reference to the textbox 'TextBox1', and the problem disappears.
Make An Array Of Different Controls?
Sep 3, 2010I've been making a table control for a few days, and I've got to the point of making it capable of accepting new data. To do this, I'm making it generate a row of text boxes, combo boxes, and date selection windows along the row that you're entering data into.
I've tried using an array of 'control' types and changing them to whatever specific control I need as I generate it. That sort of works. For example, the code under 'Case "Employees"' below will make a combo box display on the form, but 'ControlArray(i).Items.Add' gives an error because it doesn't think that ControlArray(i) is actually a combobox yet.
You might also be interested to know that everything will have to be dynamically generated since the table I'm using will not always be the same (and the Select Case code will eventually be replaced by something that checks for relationships in the database).
Dim ControlArray(NumberOfColumns - 1) As Control
For i As Integer = 0 To NumberOfColumns - 1
ControlArray(i) = New TextBox

Adding New Row Of Controls Linked To An Array?
Jun 3, 2011I am trying to make a form that is blank and will add in 2 comboboxes, a textbox, 2 buttons and a checkbox next to each other in a row. I want the controls to be part of an array, so that all controls on a row are associated with that array number.I am currently able to make the first row appear when the form is loaded, however when i click one of the buttons(which are used to create thenext row of controls) it comes up with an error stating that the index was outside the array bounds.
Here is the code I currently have:

Array Of Controls With A Unique Handler?
Jun 4, 2012I am not sure, but I have understood that, if I want an array of controls with only a method that handles a particular event, I have to define a custom control and add the handler. Is it possible that it does not work with an array of normal controls?

Nov 18, 2010I'm writing an application in VB.NET and face the following issue.

I want to create checkbox controls in a tabular form with two indices that I can use to refer to a certain time range and a day of the week.[code]I followed the article found here which creates and exposes a control array,however it is not multi-dimensional.

View 2 RepliesProperty Editor For Array Of Controls
May 21, 2012If you have a Component (or Control) with a public property of type Control, then in the Properties Window you automatically get a drop down of all the controls on the same form as the component, which is very handy. If you want to do the same thing but with an array of controls then the Properties Window shows the ellipsis and you get the Collection Editor with the Add / Remove buttons creating and deleting an instance of Control (i.e. the base class used for deriving all the others) - not quite so handy.
How do I get a list of the controls on a form and be able to select more than one? I think I need to create a custom UITypeEditor? Assuming that's right then I think I need a dialog box (like the Font dialog) with Available and Selected ListBoxes with Add / Remove buttons and appropriate code to link the control array in the component to changes in the Selected list box? Along with an appropriate UITypeEditor derived class.
Assuming that's correct, how do you get a list of the controls on a form at design time? Can I do that form design as a Windows Form, just as normal, or is it all done by hand? I've seen some code that does it with a UserControl rather than a Form, presumably that's for when you want a 'pop-up' control (like the one for Color selection)?
Populating A Form With An Array Of Controls During Runtime?
Jan 20, 2010I am new to VB 2008 express (I am a 'C' coder but have played with VB6 before). I am writing a simple program that will use the serial port. What I would like to do is, upon some trigger event, open a form, and depending on the amount of serial ports available, populate this form with an array of checkboxes with each check box corresponding to an available serial port. The user could then choose a port which would then determine the PortName.
View 1 RepliesVS 2005 - Creating Array Of Custom Controls?
Nov 6, 2009I am creating an array of customer controls by doing the following:
Dim CtlLosArray(150) As Control
Then I'm setting up the first control in the array like this:
CtlLosArray(1) = New ShieldLOSInfobox
CtlLosArray(1).Location = New Point(0, 0)
CtlLosArray(1).Visible = True
CtlLosArray(1).Show()
CtlLosArray(1).Name = "Label1"
Me.pnlLOS.Controls.Add(CtlLosArray(1))
Now on this custom control I have a panel and a few text boxes and as you can see I may be adding about 150 of these custom controls. What I am wanting to do is to be able to access that control then the item on that control based on the array. Something like the following:
CtlLosArray(1).Controls.Item(Panel1).backcolor = Color.Yellow
But the above does not work. How I can access a specific item on the customer control within the array?

Manage A Large Number Of Similar Controls In A User Interface (such As Button Or TextBox Controls)
Aug 23, 2011There is newer code in a follow up post. I suggest using the code in the later post rather than the code in this one. You can still read this post though. When designing a user interface, one should be conscious of how many individual controls are required to implement the functionality. In some cases an initial design may begin with many buttons or textboxes (for example) but then further review of
the actual required functionality allows for a reduction in the number of unique controls.
But other times, there isn't a better way (which will still make sense to the user of the application) then to have a series of many repeated controls. So in the cases where one can be certain that the best UI implementation for an application will require the use of multiple copies of a given control, then it often becomes necessary to maintain some method of managing all of those controls at various points
throughout the application. Doing so typically requires that one build up some collection of controls which can then be accessed by index in order to work with any given control; but this can lead to a lot of clutter in the code file which handles these control's events. For instance there will be some kind of collection declaration, some recursive routine to find all of the controls of interest, and then any number of event handler methods with long lists of Handles clauses, or additional code loops to wire up the event handling for each control.
Purpose Since most of this functionality could be considered a requirement regardless of the type of control being managed, or its required functionality, it may make sense to wrap all of the control management functionality into a single class. And since our first requirement is a collection of controls, then a base collection class could be the perfect starting point for our control manager. There are a number of existing thread around this topic, with some recent (at the time of this writing) ones being:[URL]..In this, and related, threads I have posted examples of a simple TextBoxManager and ButtonManager control. But again, with so much similar functionality required regardless of the control being managed, it would be technically possible to create a generic ControlManager(Of T As Control) class which can manage any type of control.
[Code]...
So in summary, one can facilitate managing a large number of user interface controls by building a "control manager" class which both encapsulates the list of control instances, and deals with adding and removing defined event handlers for every control it manages. The generic control manager class itself can be inherited and extended into a more specific class on a per-application basis in order to provide more application-specific functionality.
