.net Programmatically Creating Controls?

VS 2008 : Programmatically Creating Controls?
Sep 24, 2009I have a panel that is a set size and has its Autoscroll property set to True.I am parsing text files and then adding them to the panel. I'm extracting specific lines and then adding them to labels and text boxes that are in the panel.When my app runs, it can parse anywhere from 0-10 files at a time.If there are no files to parse, I don't want any controls in the panel. I'll be creating the controls based on how many text files I have. For each text file, I'll have 3 controls.
I'll count the text files before I parse them, and insert the controls into the panel.The problem is that I don't know how to place the controls based on the location of the panel/form. I know the panel will always have a permanent spot, but I won't know if the location parameters of the panel have changed because I won't know how many controls there will be before the app parses the files.
However, I will know the size of the controls that I'm inserting.So, with all of that, is there a way to insert the controls inside of the panel, and then based on that information, insert the others?

Form Controls Linked To Webpage?
Jun 7, 2011One section of my latest project idea involves linking several form controls to the Google map (distance calculating section), which is area I'm not familiar with.
What I would like to achieve is following: (VB2010) I would like to link two combo boxes on my form to Google map (Start Address and End Address)as well as two labels representing distance & ETA time to Google map (Suggested route, option No.1, highlighted section).
As soon as user select values from combo drop downs on my form, code performs search trough Google web page and return values to my labels on a form. At the same time database would be populated with a same search values (Start Address, End Address, Distance in Km and ETA time)
Link to a web page seems to be a very common request within community members but I did not find anything similar to what I would like to do, so it makes me think that my project idea is going to be" hard bone". I do not need Google web page displayed on my form in a split container or in any other way.
Asp.net - Getting Information (on Click) That Was Used To Programmatically Generate Asp Controls?
Jul 15, 2009How may one get information that was used to programatically generate asp controls?For example, I pulled a DataTable of user objects from the database and have organized them on a page, listing groupings such as a list of employees directly under the employer for each employer. On the page, I list each user's Username as a LinkButton. When I click one of these employees, I want to redirect the page (which is easy) and set a session variable to the selected user's UserId (which seems not so easy). How can I pull this UserId value back? These elements are not hard-coded with nice names (as they are generated in a for each loop).
Code from comment below:
Dim lnkbtnPm As New LinkButton ' is my link button. '
lnkbtnPm.Text = pmDr.Item("Username") ' where pmDr is my datarow. '
lnkbtnPm.CommandArgument = pmDr.Item("UserId")

Forms :: Programmatically Setting Controls Visibility?
Nov 9, 2009I have a panel with 5 labels and 5 listviews in it. By default they are hidden. At runtime I want only the ones shown that are needed. For example, if there are enough players for three tables then three tables should show up. I know how to make the controls visible, but not sure how to control how many are actually displayed. I also think I may have to do seperate loops and seperate the control types?

tables = Math.Ceiling(NumPlayers / NumPerTable)

Programmatically Created Controls Show Up Intermittently?
Feb 22, 2009Now everybody knows that creating GUIs that have lots of repeated elements that are evenly spaced by hand is for chumps; all the cool kids use loops and add them at runtime. Given that being one of the cool kids is one of my top priorities I decided to give this a go - as my current project involves creating a grid of check boxes and then chunking them together under one event handler. In my experience - an nice effective way of dealing with grid like structures (2D arrays if you will) is to use nested loops such as:
For intY = 0 To 9
For intX = 0 To 9
Dim chk As New CheckBox

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.

Control 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?
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
