Looping Through Controls With A Control Name?
Dec 18, 2009I have 20 controls that I created on a form. the names are like btnRing1, btnRing2, btnRing3, etc.
So I have a do while loop , and I have my variables in place. One line of code is "btnRing1.Start = PlrName" So PlrName is a variable, pulling that info from a database. I don't want to list each btnRing1, 2, 3 in each block of code in my loop.
Is there a way to use the name btnRing + 1, or something like that so I don't have to list all 20 controls in my code.
I know I can dynamically build the controls, but I can only have 20, so I need to have a little control on the numbers. So I need to have the controls already built.
Migrating Visual Studio Controls Onto Third-Party Form
Jun 15, 2009I have a Form which has a variety of controls on it backed by an abundance of code. I am contemplating replacing some of the controls with third-party controls. What is the easiest way to do this? That is, in a simple example, I may want to just replace the Form itself (i.e. use third-party form and keep using Visual Studio controls). Is it possible to migrate all the existing controls over to the new form. Or do you have to create everything from scratch on the new form (i.e. create all the controls from scratch, name them the same, and use the old code. Note I am assuming the third party controls have all the same properties which may not be the case).
View 5 RepliesControl Recommendations - Controls At The Top Of It And A Large DataGridView Is Docked Below All The Controls
Nov 10, 2011I have a maximized form that has controls at the top of it and a large DataGridView that is docked below all the controls. Its kind of like the Ribbon in MS Office. The controls cover about 1/4 of the screen at the top. I would like a way for the user to click a button to hide all the controls then automatically expand into the place the controls were so the user can view more data in the DataGridView and visa versa. For example, in MS Office Excel you can hide the ribbon by clicking a tiny button that has "^" on it.
I'm not very familiar with all the controls in Visual Studio so I would like to hear some recommendations. Is this situation ideal for a SplitContainer or ToolStripContainer or am I way off base here?

Looping Through Similarly Named Form Controls?
Jan 2, 2012I am converting a program I wrote in VB6 to Visual Studio 2010 VB.Net and have run into a problem. I am trying to cycle through 20 form elements on a form that all have the prefix 'chkCustomerItems' and then have a number 1 to 20 behind them. I am using this with a database lookup so that it there is a database entry it then applies the database item name to the checkbox's text field and turns visibility on. Here is the code I wrote:
ConnOpenClose()
Rs = New ADODB.Recordset
Sql = "SELECT * FROM CustomersItems;"
[Code]....
When it runs, I get a NullReferenceException error. This is basically the code that I used in VB6 (with some changes for .NET infrastructure).

Forms :: Looping Through Controls - Design Can't Be In Separate Panels
Oct 21, 2009I am familer with looping thru controls like so:
[Code]....
Next I have some labels on another form, that due to the design can't be in seperate panels. They are (lblChipColor1 - 6) and (lblChipValue1 - 7). I am trying to populate the color ones from the Array above. I can obviously loop thru the array, but I can't find a decent way to loop thru just the lblChipColorx lables ignoring the lblChipValue1x labels. It would be easy if they were on seperate panels. I tried adding the labels names to an array of type string and of type label, but got nowhere with that. Is there another way to group them, or build const array of label names, that I can work with?

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.

NumericUpDown Controls - Update Some Variables Each Time One Of These NumUD Controls Changes Value
Nov 20, 2011I've got a couple of these NumericUpDown controls I put on a form. Without describing too much about the form I basically want to update some variables each time one of these NumUD controls changes value. So for each NumUD I have a call to a Recalculate subroutine within their "changedValue" event.
There are actually two problems. First, if I initialize the "Value" property to something other than zero in VB2010 at DESIGN TIME it won't even open the form when I hit RUN. It gives me a "No Source Available. No symbols loaded for any call stack frame" error. The error box says "InvalidOperationException" was not handled. So if I try to set the initial value of the Value property to anything but zero of either I get this error.

View 2 RepliesForms :: Dynamic Controls Disposal - Only 50% Of Controls Removed?
Sep 17, 2010I have a query about dynamically added controls to a form. I have a series of buttons which are created and added at run time. I have a two drop down lists and two buttons which are created at design time. Button 1 creates a series of buttons called "Test 1.x" based upon the selection of the two drop down lists. This works fine and am happy with the logic.However.... Button two should remove all the dynamically created buttons from the form.This does not happen. What does happen is that 50% of the buttons are removed starting with the first one. WHen checking the loop it only enters the loop half the amount of times that there are buttons. Very strange. When the loop is run repeatability it will remove all controls. Why will my logic not remove all the dynamically created controls at once? What is wrong with my logic?
I attach two code snippets and the .net file for your consideration.Button method which creates the dynamically created buttons from the two drop down lists and adds to form
