I am currently using a listview WITHOUT a data control.When i click on the edit button the listview will not enter edit mode.
<asp:ListView ID="Lv_Test" runat="server" InsertItemPosition="FirstItem"
OnItemEditing="Lv_TestItemEditing">
<LayoutTemplate>
<table cellpadding="0" cellspacing="0" width="345px">
<th>
[Code]...
Protected Sub Lv_TestItemEditing(ByVal sender As Object, ByVal e As ListViewEditEventArgs)
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?
I have a form with a listview object and a button.I have a function that returns a Datalist.When the exception from the thread is throw in is supposed to run the Apps_Add Procedure, which it does.But on one line lstApps.Items.Add(l_apps) I am getting the following error."Cross-thread operation not valid: Control 'lstApps' accessed from a thread other than the thread it was created on."The data is being returned from the threaded procedure but I can't understand how to add the data to the ListView control without getting this error. This code works perfectly fine if I don't use threading.[code]
View 23 RepliesI need to retrieve my data from a ListView control set up in Details mode with 5 columns.
I tried using this code: MessageBox.Show(ManageList.SelectedItems(0).Text)
And it works, but only for the first selected item (item 0). If I try this:
MessageBox.Show(ManageList.SelectedItems(2).Text)
I get this error: InvalidArgument=Value of '2' is not valid for 'index'. Parameter name: index
I have no clue how I can fix this, any help?
Edit: Sorry, should have said, I'm using Windows.Forms :)

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 RepliesWould 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?

View 3 RepliesI am trying to create a ListView control at run-time and populate it with data from a SQL Query, I can create and execute the SQL query returning my desired data, I can create the listview control, but I can not get the list view to Populate data from the ListviewGroup I am creating from the SQL query. Code Snippet Follows.
Dim ItemGroupSQL As New ListViewGroup
' Create three items and three sets of subitems for each item.

This will create a ListView Box and populate the data in a very odd way, every row will have 5 columns with the same data repeated in each column. I have verified (using the commented out msgbox statements you see) that the ItemGroupSQL variable is being populated correctly. but Listview1.items.addrange(itemgroupSQL.items()) does no add the data to the listview correctly
Am I using incorrect syntax for Items.Addrange?
