I have a listview that I populate with data from a recordset during runtime. After the code has executed and I view the listbox, my columns are missing. I am 100% shure the listview is populated with data. The listview view property is curremtly set on Details. If I however switch the view to anything else eg. view=list, I see the listview items in the listbox. I need to show the user all the columns.

I created a database in my project, and added a table and some columns to it. Now after making several changes to the program I decided to add some more columns, but for some reason those new columns don't show up in the SQL query builder or the database explorer. I realize that this is an oversimplified explanation
View 4 RepliesI would like to know if it is possible if the columns of the listview can be resized automatically based on the information in the listview?
View 4 RepliesHow can i do a workaround for this? I two databases(.sdf). Database A has table A1 Database B has table A2 Table A1 is an exact duplicate of A2 minus 3 columns My dataset(.xsd) is based off of tableA2 in Database B. I can fill all my tableadapters in Database A and all info in table A1 using the dataset. My problem lies when I do TableAdapter.Update() for Table A1(Since the dataset has the 3 missing fields) it tries to update table A1 with info that isn't there and I get an error. How can I update table A1 and ignore the 3 missing columns using the single dataset? Or is TableAdapter.Update() designed to Update the Database with all columns found in the dataset ?

Everything gets added to the first column instead of the assigned column.
I have seven columns in a table Customer (custId, Date, AccountCode, Description, Quantity, Price, Amount)Also i have seven textboxes on the form from where data is transferred to the Listview. Listview has all seven columns from where data is to be transferred to the seven columns of Table Customer.I want that data should be transferred to all the seven columns of LIstview but Listview should display only last four columns and hide first three columns to display. In otherwords user may be able to see only the last four columns in Listview.

View 3 RepliesI've setup a listview with two columns. Both have a fixed width which totals the width of the control (to fill the control fully and not display a horizontal bar)This works fine as long as the form does not change, anything such as a font change on the system will cause the list view to look off alignment.LV2.jpg shows it in the designer, LV.jpg shows the same listview with a different font.Is there an easy method to fix the position or auto size the last column to the edge of the control?

View 7 RepliesI have a three column ListView.The first column has all the items in it, but if I save it to return later to put data in the other two columns it won't save the blank columns.The only way I can do it is to put a space or a character in those columns.[code]
View 3 RepliesI want to create a listview with 2 columns, on the first column, a series of names
and on the second a series of filepaths. I want each name to be linked to a filepath and then when the user clicks on the name in the first column, the filepath can be used in another bit of code. How would I do this, never used listviews before.
I am currently using the following code to store all of the items from a listbox control in an array, and then build a string based on the array items, trimming the last two character of the string to remove the ", ". I am looking to do something similiar for my multicolumn listview control but am concerned about how to store the multiple subitems for each item in the array.
Dim myStr (listbox1.items.count) as String
'store all active medications information in an array & build a string
For i As Integer = 0 To listbox1.Items.Count - 1

I seem to be having trouble finding out how to right align the text in listview columns. We have common listview control at my shop and I need to align it at run time. Currently dollar values are left aligned. Alignment. doesn't have right as an option.
View 2 RepliesI want to separate each text into their own Column in VB.net. How do I achieve this?
Screenshot:
Each entry is separated with "|" .
My Code:

Dim folder As String = Environment.GetFolderPath(Environment.SpecialFolder.Personal)
Using sw As StreamWriter = File.AppendText("My Expenses.txt")
sw.WriteLine(DateTimePicker.Text + Space(1) & "|" & Subject.Text + Space(4) & "|" & Category.Text + Space(5) & "|" & Amount.Text + Space(4) & "|" & Peyment.Text)
sw.Close()
End Using
End Sub
I set the width for my ListView columns in the designer, in run time they always shrink back. I have no idea why, could anyone shed some light on this for me - possibly a solution to keeping them exactly the way I set them in designer ?

Using Microsoft Visual Studio 2010 Ultimate - VB.Net
I'm writing an application where as many of other applications fulfill the requirements to be as an app , having it's statistics schema. Thus I made a form where I have a combox(of query category), a textbox(as searchfield), two datetimepickers(from and to) a listview and a button to fire the event with functions in it. I'm all set except for a minor issue I've encountered during my very first experiments with ListView control. Thus far I didn't know that VB users are stuck with that control's property options (whereas DataGridView has way too many), especially when it came to Column reordering/s. With the simple but not satisfying property Sort I couldn't find a proper solution to my issue.
when I click on of the columns in the listview to do a Number/Date/Text reordering (descending>ascending, via-verse). Not to forget to mention there a limited number of columns most likely 2-4 max.
The listview control has lvResults name and has for now columns inserted as "Country" and the other for subitems "Total Spent".
One e.g. of the values inserted to it is like this :
[Code].....
If pressed on Total Spent, should reorder from highest to the lowest number and via-versa. If pressed on Country should reorder from A to Z or via-versa.
First off i just want to take a bow to all the vb gods out there..I am trying to implement the sorting class form article 319399 in the knowledge base [URl]..on step number 6 it says to "Paste the following code into the ColumnClick event for the ListView:"so i created a sub to handle the ColumnClick event
[Code]...
I'm trying to set something up where the user can sort each column by clicking on the header... i've looked at some other examples and they seem pretty longwinded..so far i have the below...
VB
Private Sub resultsListView_ColumnClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ColumnClickEventArgs) Handles resultsListView.ColumnClick
Dim oldsort As SortOrder
[code]....
which works fine... but only for the first column in the list view.Is there a way of specifying which column to sort based on which is clicked?
So I made a Listview with 3 columns, I also added a ContentMenuStrip on to it that will delete selected items. But the thing is that I can only select the first column.
How can I make it so I can actually select all my columns?

If you are wondering about error 1 that error has nothing to do with the other two errors, it's a formatting error.
I am not sure what I am doing wrong at this point, I have tried to Google it but no luck. Basically I need 4 columns on in my ListView that each row will be able to add data to.
