I have started the familiarize myself with WPF and have gotten stuck with the ListView I've read a lot of documentation about binding and I can't seem to find how to populate a ListView programmatically. It seems like a lot of work to create the binding and classes, etc, just to fill a ListView.
1. If you want to populate a ListView with data that a user has inputted, is the correct way in WPF to populate the ListView with binded data?
2. How do you add items and subitems to a ListView in code? (There doesn't seem to be a subitems in WPF.)
I have an MS Access DB with a Table setup with the columns that I need.
I have it linked into a form, with the requisite BindingSource, TableAdapter, BindingNavigator, etc.
On the form, I also have several textboxes linked back to the table. I can populate the table via the + (add new) button in the BindingNavigator and then filling in the textboxes (and saving of course).
Is there a way that I can put a button on the form and populate the table automatically? I want to do this via a textbox to control the number of records added - that way, I can put in an 8 and have 8 blank records added to the table via this one click (and don't have to enter the default info in for the 8 records one at a time).
I've attempted to do this by calling the BindingNavigatorAddNewItem_Click subroutine, filling in the textboxes and then calling MapBindingNavigatorSaveItem_Click subroutine, but this does not work.
I have a form with several text boxes and check boxes.These are populated via a sql data reader during the form load event.
Private Sub TextFields_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _ TxtBUsername.TextChanged, TxtBPassword.TextChanged, CBoxAccountDisabled.CheckedChanged
Can someone help me with this code? I just need to make it so there is no limitation on how much data is loaded in the columns or rows, it populates very nicely for smaller comma delimited files , but if I try to load something that goes for example over to AV column, it errors out.I don't care about VIEWING this data, I am just trying to get it into a LISTVIEW so I can access the data for other methods in my code.Index was outside the bounds of the array.

I am trying to populate listview with the code below:
Public constr As String = "Data Source=adesina-pc;Initial Catalog=AdventureWorks;Integrated Security=True" Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
I have a listview with 6 columns. The first, hidden, is a key value. The other five are FirstName, MI, LastName, Gender, and CurrentGrade. When I go to populate the listview, I pull a datatable and do this:
For Each dr As DataRow In dt.Rows Dim lvi As New ListViewItem(dr("StudentKey").ToString) For i As Integer = 1 To 4 lvi.SubItems.Add("") [Code] .....
But when the form loads, I get the MI in the FirstName column, the First Name in the LastName column, the LastName in the Gender column, and the Gender in the CurrentGrade column. The MI is blank. I've run it in debug, and the correct values are in the correct subitems. But for some reason, when the ListViewItem is added to the ListView, the subitems get all jumbled.
I feel like I must be missing something obvious.I have a listview with 6 columns. The first, hidden, is a key value. The other five are FirstName, MI, LastName, Gender, and CurrentGrade.When I go to populate the listview, I pull a datatable and do this:

Im desperately trying to populate my Listview called "Listview1" with my stored procedure that I have create on my SQL Server 2005. Ive got quite far as seen below but I still dont know to to effectively populate the Listview1 with the data retrieved from my Stored Procedure. The below connection does work but I dont know how to use it now with my Listview.
Imports System.Data.SqlClient Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
I'm playing with an Access database file. And I want to populate a ListView control with Access data. I'm not going to use the DataGridView control. The following is my Access file, which has a table labeled Employ1 with three fields (Usernames, FNames, LNames) as you see below.
I googled, searched and tried houres but I can not find a simple code/class that does the following: I have a SQL database and I want to show some colums of a table in a listview... Not so difficult I thought, in VB6 it was fixed in 2 minutes but now I'm struggeling for houres... I found Imports System.Data.SqlClient but further then this, I fail...
I have a tab control in my form and inside it I put a listview. What I wanted to do is populate the listview everytime I clicked on each tab. But I don't know how to do it.
Here is the bit of my code
Public Class Form2 Private Sub PopulateRecords() Dim TSR As New ADODB.Recordset Dim STRSQL As String = ""
I want to show a list of files and folders (names + their icons) inside a given directory with a ListView control or equivalent. I understand that ExtractAssociatedIcon gives you the icon of a file, not a folder. So what are my options for this objective? I don't really have a problem if I have to separate folders and files like the following.
Dim fi As New IO.DirectoryInfo(f) 'f is the path of a given directory For Each subfolder As IO.DirectoryInfo In fi.GetDirectories() ImageList1.Images.Add(My.Resources.FolderIcon)
if this question has already been answered many times, but I am new to VB and I don't really understand any of the examples I have found by trying to research this topic. I am using VB 2008 Express Edition. My List View is called listView.
What I want to do is gather the data that displays in my listview (called 'lstData') when selected and populate my textfields with it's information.[code]
Here is the code I am playing around I am getting error populating the table cells into my listview. In my codes it is always add only in one cloumn in my lv.
Private Sub DumpTables() Dim t, c As Integer ' Used to count tables and cells. Dim IWebDocument As HTMLDocument
I have an MDI application, say name of MDI is MDIParent. From form1 I am adding new tab pages to form2. In the first tab of form2 I have generated a ListView by calling a ListViewCreate() function in Load event of form2. I am not able to generate ListView for the new tabs. I tried calling the ListViewCreate() while adding newtab. But, it is not creating listview nor throwing any error.
I'm using the following code to sort a listview:It triggers off the column click envent.What I would like to add to my code is to manually trigger it in the code. My code enumerates all installed apps on a PC and places them into a listview. I then want to sort the listview as the next step in my code but the sort code from the MS site looks for the column which was clicked:
Private Sub lvVisualResults_ColumnClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ColumnClickEventArgs) Handles lvVisualResults.ColumnClick ' Determine if the clicked column is already the column that is
I have programmatically created a listview in n # of tabpages to display information gathered from an SQL database.Once created, i want the user to be able to select an item from any of the listview's. How can i reference the selected item?[code...]
All i want is to know that when a button control is clicked, which item is being selected in which listview?
I am trying to programmatically select all items, including subitems, in a listview and can't seem to get the result I am looking for. I have FullRowSelect = True set and when I click on the items, all is fine. However, if I use the following code, only the ListViewItem is selected and not the item's subitems. Is there a way to achieve this?
I have a form which the datagridview will be built manually by reading in certain data from a text file (this is because the data in the text file will change periodically)The code is correctly adding the proper amount of rows but it is NOT putting the required values in the cells. Any thoughts?
I am working on a weboage that will display questions and answers (maybe 5 at one time, maybe 7 at another time) returned from a database table. The questions will each be displayed in a div and the related answers displayed in another div. The question will have an icon "Show Answer / Hide Answer"
How can I go about creating a div and then populating it with values from a table?
The general problem is that I can't get the foreign key in one of my child tables to populate the primary key from the parent table. I have a parent table named "ISSUES" and a child table named "ISSDESC". The primary key for ISSUES is ISS_ID which is an autonumber. The foreign key is ISS_ID in the ISSDESC table which is just a number. I'm using MS Access and an OLEDBConnection as the method. I've created the relationship in MS Access and also created the datarelation in the VB.NET code.
in short not populating, below is the code i'm running with but it isn't loading. Newer to Datagridview so I know I'm missing something. The SQL import I've successfully done with a listbox and borrowed some of the code from that.
Public Class Form1 Private Sub gettournies() Dim sqlconn As New SqlConnection
