Maybe if I knew the right termanology, I could find the answer myself.. I am going to run a fairly long list of "If"s that will determine if certain controls appear on the form or not. In it's simplest form would be:

I am writing an application and I do not know how to reference a group of controls inside a group box. I will include the code I have written so far and a picture with a detailed explanation as to what I am trying to do. Feel free to comment on any discrepancies that you may notice in my code.

I am trying to develop a recipe manager that allows a user to create a shopping list. I've already determined that I want to use a list view for this job. I want to be able to group the items in the shopping list by the appropriate grocery aisle (i.e. Dairy, Bread, Canned Goods, etc.) I'm not sure how to assign the items to the appropriate group as the user selects each item.
I haven't started actually building the application yet as i'm still in the development stage, but i have been testing the list view out to figure out how it works. i've figured out how to add items. i just don't know how to specify the group that each item should belong to.

I am trying to work out a way to group a collection of items like an enum so that I can access them through code else where in my program. i.e I have list of items and sub items

Would anyone be able to advise if this is possible or achievable.
I have an ASP.NET app with lots of textboxes all over the page that need updating at various points through program execution. These textboxes actually belong to a certain class, so for easy updating I thought I could create a Dictionary(Of string, object) and add the control.ID and the control to it and then for updating do something like this:

The documentation has an example about grouping on multiple properties[code]...
Is it possible to rewrite the original query to just return IEnumerable(Of CustomerRegionGroup), or do I have to use the anonymous type, and run a second query on the result of the first?
1) Which one works better? BackgroundWorker or Multithreading?I have to do lots of processing in my application, I'm not too sure how the two of them works.
2) Can I assign controls in a GroupBox to a thread?Let's say I have to login to a certain forum twice with different accounts, so in GroupBox1 (thread1), I'll be logged in with username "asd", in GroupBox2 (thread2), I'll be logged in with username "zxc", and I have to do lots of processing (mostly html parsing) from there. Is this possible without stressing on memory usage? I'd like to keep my program memory usage under 10k.

How can I group controls in my Form?
I don't need groupbox or panels, just something in the code...
To make it clear:
I have one form, Form1.
I have 3 buttons: Button1, Button2 and Button3, and I have 2 labels, named Label1 and Label2.
I have 2 "groups", in group1 there is Button1, Button2 and Button3. In group2 there are the two labels (Label1 and Label2).
But how can I program that, that if I write (for example) "Group1.Hide()", then everything In Group1 hides (visible = false). And so on with group2.
I programatically add a group of UserControls to a flowLayoutPanel control.
sometimes I need to destroy that group of controls, but have no idea on how to do it.
assigning the flowLayoutPanel variable to nothing only erases the pointer, but the controls remain in the window.I have found a page in MSDN saying that the best way to destroy a control is to call the DestroyWindow API, to destroy the container window. But I don't want to destroy the container window.
I have 53 text boxes in my windows forms application. I need to save the "text" of all the textboxes into a single file. Is there a way, I can control all the textboxes as a single textbox group and use its properties.
For example: Can I write something like :
For i As Integer = 0 to 52
Textboxgroup.text = TextBox(i).Text
Next
??
Using VB.Net and C#.Net.

How would I dynamically enable/disable group boxes based on a radio button selection? I am trying to do it with two group boxes. The group boxes are called grpSelectChars and grpPWAutomatic. The radio buttons are called rdoChooseChars and rdoRandomlyGen. if rdoChooseChars is selected then I want grpSelectChars Enabled and grpPWAutomatic Disabled. in the load sub I have rdoChooseChars Checked
Private Sub PWGenerator_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I was wondering if there is a way to group controls together without using any containers such as panel, group box, or container.
View 4 RepliesI have a group of controls dynamically added to a forms with a name like "OptionID_#" where the "#" is unique number.1st I need to check if these controls are checked/unchecked, but am having a difficult time even finding them to make that first check.I thought controls.find might work, but Controls.Find ("Option ID_" True) dues not seem to find my controls.2nd I need to get the "#" from each of those checked options.I think that Split(conControl.Name, "_") should work to get me two different parts one with the OptionID, and the other with the "#".Still stuck on the first part though of actuall locating the controls I need.

I have a form with many buttons on it and I would like to loop through all the controls in a group control and find out which button is clicked.
I plan to use the click event of the button and I know it's easy to create a click event procedure for all of the buttons but would like to avoid that.
The group control is called GroupFilterButtons.
So basically what I'm trying to do is write data from an XML file (a "save file") back into the form. My controls are in all different group boxes (makes it much easier for showing and hiding groups of controls dynamically). I thought about and am putting each control's Parent name into the file, but can't figure out how to get that parent name back into the DirectCast within a For...Next loop so it will actually cast the data into the control.

I'm a bit confused here. I'm copying all the controls from one form to a panel on the main form and for some reason only about half of them copy.
Private Sub switchComponent()
Dim selection As String = TreeView1.SelectedNode.Text
Panel1.Controls.Clear()[code]....
When stepping through the code, serverDic(selection).Controls has 12 elements, but only 6 of them get copied. Next time this gets called, only 3 get copied. Does Panel1.Controls.clear() somehow kill the references?
EDIT: Just to show that there are infact 12 elements in the collection:
Im trying to loop through a collection of controls see code:

I often see code snippets for handling each control of a certain type on a form or panel, etc.They always start with For Each ctrl and the do a test for control type.Many .NET users are not aware, as I was not until I tried it recently, that we can LINQ on the controls collection.Below is a simple sub I created for resetting every checkbox on a panel I use as a validator.
Private Sub ResetCheckBoxes(ByRef pnl As Panel)
Dim ctrls as System.Collections.Generic.IEnumerable(Of Object)
ctrls = From c In pnl.Controls Where TypeOf (c) Is CheckBox

Does anyone know how I can access the FontDialog's controls collection? I would like to disable the Font Style ListBox, set the Font Style's TextBox to readonly and disable the UnderLine and StrikeOut CheckBoxes.
View 3 RepliesHow to get the last instance of label control in List (of Control) using linq?
View 4 RepliesI am writing a simple control translation function that reads an XML file containing control names and their localized text. Within the application, each time a form is loaded, it iterates through every control and tests to see if that control is defined in the XML file. If it is, it then sets the control text to whatever localized text is defined in the XML file.
There are some tests and additional requirements (i.e. nested loops) for TabControl and MenuStrip etc., but the control that is giving me the most trouble is the ContextMenuStrip.[code]...
