Nest Groups Within A Listview ?
Aug 7, 2009
I want to know if it is possible to nest groups within a listview. I started with a listview in my application that contains list types and this worked fine. I have now been asked to group by Product, then Week Commencing and finally by List Type; This would envolve a 3 group nest and i just cant figure out how to do it (if at all possible).
like so...

listview items 1

If what I am trying to accomplish is beyond the listview control, can anyone suggest a possible avenue to explore?

I state that I am Italian and I am using a translator.
I have a problem that I can not fix.
I have a listview with a group. The property view is SmallIcon
On my windows xp everything works perfectly, but I tried the same thing on Windows 7, and I have this problem: When I add a bit of items in the listview I have some strange display problems, no errors.I made some screenshots to let you know

Any snippet of code for adding groups at run-time to a listview. I am currently listing books (and stats) without groups via the following code which is executed in a loop (one pass per book title).
item = New ListViewItem
item.Text = seq.ToString
item.SubItems.Add(Mid(titlenode.Nodes(N_CSTAT).Text, 3))
item.SubItems.Add(Mid(titlenode.Nodes(N_JSTAT).Text, 3))
item.SubItems.Add(titlenode.Nodes(N_PUBLISHED).Text)
[Code] .....
The listview is set to details view. What I want to do is group the book titles by series. For example, books by Michael Connelly may be grouped by "Harry Bosch", "Jack McEvoy", "Mickey Haller", etc. I can create a new group for each new series by
groupnum += 1
group = New ListViewGroup("group" & groupnum, _
System.Windows.Forms.HorizontalAlignment.Left)
group.Name = "group" & groupnum
group.Header = series
But I cannot find how to add the group to the listview and add the new item to the associated group.

on button.click event,Dim category As New ListViewGroup(cbType.Text) If Listview.Groups.Contains(category) Then Arggh! this should work. Listview.Items.Add(lvi).Group = category
Else
Listview.Groups.Add(category)
Listview.Items.Add(lvi).Group = category
End If
If cbType.Text was "Dog", it will add another "dog" group header every time I add an item having selected dog, when I want to add the item to the existing dog group.

I constructed a form with a listview and programatically added items and groups to it. It worked perfectly. I have now made it an MDI child form and the grouping disappears. I even removed my code and simply added groups and items through the form designer. The items display fine but not the groups.

Update: (Please vote to close) This question is unresolved, and is likely a list view bug.It can be replicated by using the example code from the MSDN link below, and adding this code after the list view initialization code:
myListView.View = View.Details;
myListView.Columns.Add("Column1");
myListView.Groups.Add("group", "group");

I am currently using VB 2008 and there is a form I'm using which contains a listview control. I am dynamically filling the listview with groups and items. After I fill it up, it is supposed to look like this:
[CODE]...
Each item is specific for each group. The problem I have is that when I maximize the form to full size, and everything expands, the items change positions into something like this:
[CODE]...
How can I make the listview keep the items in the "row" view always, instead of the "column" view whether I maximize or not?

I think I already know the answer to this, but I figured it would not hurt to ask.
Is there any possible way to nest Databound DataGridViews in .NET? What I would like to have happen is for each row in the DataGridView to have a button to expand, which would then give me a DataGridView underneath that. I would like this nested DataGridView to also be able to do this, so I could go n levels deep with them.
Is this possible with the .NET Winforms standard DataGridView? (Or another standard .NET control?) I have seen people reference some third party controls, however they are really expensive, and I don't really want to go that route.

I got my code and the number are finally right the only thing is i can not get it to loop right. It should ask the user if they would like to buy more bars and if they say yes it should continue if it says no then it should exit but everything i am trying is not working.[code]

I have a webcam directly over a chicken nest. This camera takes images and uploads them to a folder on a server. I'd like to detect if an egg has been laid from this image.I'm thinking the best method would be to compare the contrast as the egg will be much more reflective than the straw nest. (The camera has Infrared so the image is partly grey scale)

I think the short answer is you can't, but there has to be someway to make it happen. I want to make a list of items, that then have a list of items within them, nesting only one level.[code]...

If I look at some classes in the framework, using reflector, I can see that forms and user controls are made private and nested into a parent class.For instance, I have a control which makes use of pop-up form that is specific to that control.At the moment, I make the pop-up form friend accessible.If I wanted to do it the framework way, I'd make it private and nest it into the control class.If I do this, however, I can no longer use the ide to design the form and I get errors when I try to compile.

I have a block of related sub routines I would like to "group" together within class to make navigating a littel easier. When I say group, I mean achieve the same functionality of being able collapse and expand a block of code as would with single procedure or class. Two alternative ways I can think to accomplish this is either use a partial class for those procedures or use namespace. I just wanted to see if VS for VB.Net had another way to be able group and collapse blocks of procedures.

I have a string of hexadecimal numbers that is generated by the program which I created.
B 53 D0 A1 58 3 DA AF E2 15 9E E 68 F0 65
Given by:
HexText = HexText & " " 'the space makes the characters separated into groups
I want the single characters "B" and "E" would both have 0's before them so that the text is all in groups of twos. How can this be done?
0B 53 D0 A1 58 3 DA AF E2 15 9E 0E 68 F0 65
instead of:
B 53 D0 A1 58 3 DA AF E2 15 9E E 68 F0 65
I was thinking I might be able to do a for Loop and go through the text and if it's a single character add a 0 before but don't understand the exact syntax behind it:
For i = 1 to Len(HexText.Text)
'If a character in a group of two of the string is not equal to a hexadecimal number, make that character equal to 0.

I am writing an application where active directory validation is required before accessing the main form. There are 2 forms. Form 2 is the login form and form 1 is the main form. The main form would have a simple look, with about 10 checkboxes.I have managed to get the authentication working great but what now need to do is validate groups. Say if "user A" is in "groups A,B and C" and "user B" is in "groups B and C" i would like for them to use my login form, once they log in, the groups that they are members of would appear in a listbox on either form, (whichever is easiest) and is hidden from the user ... if they are in group A, then the main form would show only the first 3 checkboxes, if they are in group B, then it would show the 4th and 5th checkboxes, if in both groups then show the first 5 checkboxes etc.It is a simple idea, but is complicated to explain.As i said, the login form is working with the active directory... here is the code for the login form:[code]Form1 in the code is my main form, and wish for it to change according to which groups the user is in.

does a big business in shirts, especially for groups and teams. They need a project that will calculate the price for individual orders, as well as a summary for all orders.The store employee will enter the orders in an order form that has text boxes for customer name and order number. To specify the shirts, use a text box for the quantity, radio buttons to select the size (small, medium, large, extra large, and XXL), and check boxes to specify a monogram and/or a pocket. Display the shirt price for the current order and the order total in labels.
Include buttons to add a shirt to an order, clear the current item, complete the order, and display the summary of all orders. Do not allow the summary to display if the current order is not complete. Also, disable the text boxes for customer name and order number after an order is started; enable them again when the user clicks on the button to begin a new order. Confirm the operation before clearing the current order.
When the user adds shirts to an order, validate the quantity, which must be greater than zero. If the entry does not pass the validation, do not perform any calculation but display a message box and allow the user to correct the value. Determine the price of the shirts from the radio buttons and check boxes for the monogram and pockets. Multiply the quantity by the price to determine the extended price, and add to the order total and summary total
The assignment also requires a pop up message "Daily Summary" with total shirts sold, total sales, and average sale per customer.So far I have this as my code but I am not sure what needs to change in order to display the correct total shirts- mine only displays the last accepted shirt order.

For a race, I am trying to evenly disperse the heats for smaller race groups within those of larger race groups. I do not want the smaller groups to finish too early and I am also trying to minimize groups running back to back heats.
As an example:
Group A has 4 heats
Group B has 2 heats
Group C has 1 heat
The resulting schedule would look something like this:
A1 B1 A2 C1 A3 B2 A4
To complicate things, there could be any number of race groups and each race group can have any number of heats.

I'm building an control interface for a system that consists of 1-4 modules. In my interface, each module has its own control set, grouped in a groupbox. I only want to show the control groups for the modules that are actually connected and hide the rest.
This is easy to do with the visble property.
I also want all of the groups to be stacked vertically in the UI such that when one is hidden, the rest below it shift up into its place as if you deleted a row in a table. It needs to be able to come back just as easily.
