With the ASP.NET Repeater control, I am used to being able to access my data item values in the ItemDataBound Event Handler by doing:e.item.dataitem("column_name")
However, it seems with the ListView control this is not possible. How can I access the data item values?

I am having some trouble accessing the data in a listview. The data in my listview is popluated from the database which works fine. What I want is the user to be able to click on the entry in the listview and it show them a messagebox with all the data from the listview. I have 1 main item and 2 subitems in the listview.

This is just stupid. I've been at this for over 5 hours and can't figure out why my freaking commands aren't firing properly. The only ones that fire properly are the Built-in commands "Edit" & "Cancel"
<asp:ListView ID="NewProduct" runat="server" DataSourceID="NewProductSDS" DataKeyNames="ID">
<ItemTemplate>
<div>
<asp:LinkButton ID="accept" runat="server" CommandName="Accept" />
<asp:LinkButton ID="edit" runat="server" CommandName="Edit" />

Im doing that when delete button is clicked in the listview:(code simplified, it delete as it should)
Protected Sub rlvCarts_ItemCommand(sender As Object, e As RadListViewCommandEventArgs)
If e.CommandName = RadListView.DeleteCommandName Then
[Code].....
The issue comes when deleteting it will perform itemdatabound twice (but listview prerender once).

I am trying to add an attribute to a tag with ID 'SubNav2' on ItemDataBound which is in the HeaderTemplate of a repeater.ut I keep getting the error: Object reference not set to an instance of an object.Which i think is because it is not finding the object with ID 'SubNav2', am i going about it the correct way?
CODE BEHIND
If e.Item.ItemType = ListItemType.Header Then
Dim ulSubNav2 As HtmlGenericControl = CType(e.Item.FindControl("SubNav2"),

The event handlers in my parent class are never called though the events are raised in the child class.
The Code:
Public Class childForm
Public Event checkboxchangedEvent(ByVal checkbox1 As Boolean, ByVal checkbox2 As Boolean)
Private Sub checkboxchanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged, CheckBox2.CheckedChanged

remove an event handler from within the event handler?
I have a class that gets data from a hand scanner. When the scan is complete and the data is validated, the class fires a custom "ScanComplete" event and returns the data in a custom EventArgs.
In the calling program, I'm creating an instance of the scanning class and adding a handler for the "ScanComplete" event. In the event handler I get the data that was scanned and then remove the handler.
It seems to be working but it feels wrong to remove the handler while I'm running inside the handler. Will this cause a problem?

Basically in visual basic 6 I could access word tables in existing templates with the code owordactivedoc.tables(1).select() where owordactivedoc refers to the active word document and tables(1) refers to the first table in the template.Trying the same code in VB 2003 just leads to errors. Secondly how do I access bookmarks or alternatively word variables.Furthermore how do one deploy web.services. For example the current program I am building is for another computer. Simply copying the web service to Inetpubwwwroot dont work because it is not picked up by the Internet Information Services program. I have to create the web service in vb2003 on the other computer change msconfig manually. Copy and paste the existing service vb file in the created folder replacing the empty vb file.

I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag

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?

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?

Here is a problem with focus. I have a container(e.g. Panel) which contains some controls. How can I detect the focus event whenever any of the controls in the container has received or lost focus? Do I need to add handler for each control?
example: If all controls in the container have no focus, the container will report as inactive; if one of the controls has focus, the container will report as active.

I ma using DevExpress controls (which doesnt matter for this example). I have a lookupEdit control and I never want the EditValue_Changed event to fire. Can I use RemoveHandler to do this? If so can someone give me a code example of doing this? Should I put RemoveHandler in the load event of the user control I am creating? Or does it go in the EditValue_Changed event of the lookupControl?
