I am using VB express 2008 with MsAccess as database. How to bind a dataview to a listview i.e. how we can add data to a Listview from a Dataview.
Dim
DailyExpenses As New DataTable("DailyExpenses")
Dim dv As New DataView(DailyExpenses)
I read in some post something like under but when i tried to implement that ItemsSource is not a member of Listview:
listview.ItemsSource = dtView
i am trying to add several rows to a dataview before bindng it to the datagridview. I have tried several variations of the below code but only the last row will actuall load into the grid. Probably doing something stupid.
My code is:
dvInspectDetail.AllowNew = True
Dim newRow1 As DataRowView = dvInspectDetail.AddNew
newRow1("IDetail") = mDetailNo.ToString
[Code].....
Most of the project I do, I use the datagridview to display the data from the database. What is the different between the datagridview and listview? If I want to display the data from the database, should I use the datagridview or the listview?

I have a VB.NET application that creates a dataview from sql table and exports it as an excel file. Now, the data is inserted value by value. Instead, I want to insert the data from the dataview as a bulk insert on to the excel file. The data insert should happen from the third row, as I need to use the first two rows for column insert and data formating (which is done later in the program using excel macro.).Heres the code I wish to upgrade :
Dim strConn As String = "Data Source = LV-SQL2; Initial Catalog = TC_MASTER; user id = SQL2JOB; password = ******** "
Dim strSql1 As String = "Select Customer_id_1, file_name from customer_list_DA order by customer_id_1"
Dim da1 As New SqlDataAdapter(strSql1, strConn)

im trying to select some rows based on a criteria, i was wondering is it faster if i create a dataview (based on the criteria) and then loop through the view? or should i loop through the entire datatable and check the criteria manually.

I 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?

View 2 RepliesI've created a ListView called ListView1. In the first colum, I want to add either a stop sign or a grean light.
I create the columns
HTML
ListView1.Columns.Add("Item Column", -2, HorizontalAlignment.Left)
ListView1.Columns.Add("Column 2", -2, HorizontalAlignment.Left)
[code]....
This seems to generate alternating stop signs and green lights in the first column. Instead, I want to be able to decide which one goes on each row on the fly, as well as change them later.
Maybe someone here can shed some light. I created a Windows Mobile application with a ListView control. I want to add items to this ListView.

I have a listview with 3 columns.
first - Process Name
second - Process Path
3rd / last - Process ID
I can easily get those details with mainmodule.filename and etc. But my main problem is with adding them to a listview.
I know I can do something like
Code:
ListView1.Items.Add("processname").SubItems.Add("hello")
But how to add a thirds subitem when I got a list of process in my listview. A button is click and then the listview will be added with processnames and paths. But I cant add the ID's cuz you have to give a specific listview item to add another subitem.

I currently have a line of text in my listview that is too long for the current width of my
listview, without increasing the width of my listview, is there a way to add a newline within the

the text?
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)

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.
