I am using a nice shopping cart I found online. I would like to translate this code to use a repeater or listview and dynamically retrieve my data, but I cannot seem to find a way to group my data correctly.I know the ListView can group by a certain amount of items, but I have not found a way to do it with this scenario.The shopping cart works by having a ul list of items, followed by their details in the div below. This process starts again by getting three more ul items, followed by three more details. How could I do this using a ListView or repeater? I have not found a way to repeat both of these sets of data I need in a group of three.[code]
View 1 RepliesI have finally got my head around sorting listviews.My problem is that I have the listview with columns (Name, Folder, Date) and when I sort it by date, it creates groups for each indiviudal date (shown on the left). Is there a way to get the same result as Explorer on the right?
View 2 RepliesI am using a treeview to display projects, tasks, time entries, and the people who are working on a project. I would like to allow the user to define a custom grouping (ie. Project->Task->Time Entries or Project->Date (of time entry)->Task->TimeEntry).The relevant groups would be Project, Task, Time Entry, and Person, with some metadata from them. I want to have some modular way to allow a user to specify how they would like to display the information. Does anyone know of a good method by which this can be done? I currently have hard-coded a display which looks like this:
Project
Task
Time Entry

I am trying to make a listview custom control based on the standard listview control that will allow me to drag a column header outside the standard listview control and drop it on a panel. I plan to use the drop event to determine which column I should group by view on.
View 2 RepliesI have 3 forms, one frmMain - main form, second is frmUserType- childform, and the last frmCreateUserType. In the main form I have a menu item to open my frmUserType, In this form I have a button to open another form which is my frmCreateUserType, In this form I have a button to add records then update the listview in frmUserType. The problem is the listview will not access with my add button control in frmCreateUserType. I tried not to used mdiparent declaration for my frmMain and frmUserType as children and it works, so meaning that the problem is showing my frmUserType as childform?I am using vb.net 2008

I'm using ListView control, with SmallIcons style in VB.NET. Icons are loaded fine, but when I start to scroll ListView down or up from scrollbar (clicking from arrows), rowheight drops to about half from normal in next 20-30 rows below/above upper/bottom row (depends from the scrolling position). After 1-2 seconds, ListView is "refreshed" and scrolling continues normally. When focus in on the ListView and I'm moving up/down with arrow keys or PageUp/PageDown, everything is normal. Any suggestions, what is happening? SmallIcons size is 16 * 16. Is it compulsory to set "Blank icon" with SmallIcon size to all rows, when adding them or what? Wasn't like that in VB6, how is it in VB.NET?
View 4 RepliesI have a vb-2008 program that contains a (listview) control.
View = details
AllowColumnReorder = true
Lets say the table has 3 columns (a,b,c) and 1 row of data.
a b c
1 2 3
I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.
c a b
3 1 2
Statements like:
.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString
Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.
How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?

Would someone mind explaining to me how visual basic treats a ListView object? It seems that if I create a new ListView and make it equal to the old ListView it's like filling the new ListView "ByRef" so to speak.
I'm running into problems because of this when I try to do some processing with the selected items in a new thread. Does anyone have a better solution to this than using a delegate to call a fucntion which populates an ArrayList with the ListView.SelectedItems and then returns the ArrayList?
Edit: Seems no-one is answering well let me ask a "hopefully" easier sub-question.

My VB.net application has a lot of application settings, is it possible to group them somehow(other than having a common name)?For example, my application has a lot of winforms each of which needs to save some information about itself. Is it possible to use something like:
Form1.width = My.Settings.Form1.Width
Form2.width = My.Settings.Form2.Width
etc.
I've a large table of Items and I need to organize them by Category, then by Year and then by Month.Item has CategoryID and Dated properties.I got this far:
Dim Items = From Item In DB.Items _
Group By CategoryID = Item.CategoryID _
Into Categories = Group _
Order By CategoryID
But where I put the:
Group By Year = Year(Item.Dated)
and the
Group By Month = Month(Item.Dated)
The final result should be something like this:
For Each Category in Categories
For Each Year in Category.Years

I am trying to group various controls (of the same type, e.g., labels together, buttons together, etc.) on a form using a tag or a name of some sort so I can identify all those that belong to tag 'A' and those in tag 'B'.

Because all of my applications begin with the product in the Title bar can this be achived.
I have multiple sub's that i'd like to group together, however all of the groups need to be in the same class.

I have a class called Trigger. within this class, I can perform a variety of functions, the main of which is to monitor a specific condition. In this class I have a bunch of class variables that are used to setup the condition as well as for information purposes after the condition has executed. All the conditions are stored in a database and when I start the program, I create a New Trigger class for each condition and store the variables (name, desc, action to perform once the condition is met, etc.) I was thinking about changing the class to create a Structure called Configuration where I would store all the variables. But then I would have to save the Configuration within the class so it could be used later on if needed correct?
[Code]...
but in looking at this i realized that I am creating a new structure and then creating a new trigger class where I am saving the Configuration structure which essentially seems the same as just using class variables as I was before. I also looked at creating a Configuration Class and a Trigger Class. then from the main class I would create all the Configurations and have a shared Trigger class that monitored all of them instead of having a single Trigger class for each Configuration. Using this method i could create a hash table that kept track of each configuration that was being monitored and stop it if required.
Does either method sound more appropriate over the other. I am just trying to understand when/why to do things a certain way.

View 2 RepliesI am making a report using the reportviewer. I have grouped the data and the group works. But when I try to put some data in the group header, I get the following error:The Value expression for the textbox Dep_Name refers to the field Dep_Name. Report item expressions can only refer to fields within the current data set scope or, if inside an aggregate, the specified data set scope.

I am developing a Windows application that reads from a database and creates a total and subtotals for the records in the database. I am supposed to include a Try...Catch statement that reads the records in an Access db table and adds an item to the ListView control for each record.

I have already gone through and created my Form_Load event that creates the columns needed in the ListView. I have created the beginning of the Try...Catch statement that opens the database connection.
