How do I get the SuspendLayout and ResumeLayout to work correctly in regards to a listview. I have added these lines of code before and after I have added the items, yet each item is still being displayed as I add each item.
My code:
Dim x As Integer
Dim startTick As Integer = Environment.TickCount
lstFiles.SuspendLayout()
For x = 0 To UBound(cacheListArray)
[code]....
I am adding 2000 items. This takes 7 seconds. I was told that it should be a lot shorter than that. Is that correct?
New code:
Dim ListViewItemArray(-1) As ListViewItem
ReDim Preserve ListViewItemArray(UBound(ListViewItemArray) + 1)
ListViewItemArray(UBound(ListViewItemArray)).Text = file.Name

Nothing is being added. What have I done incorrectly?
I have a VB.Net Winform showing checkboxes inside the ListView which works fine. I want to know how to make the checkbox work like the RadioButton. ie. I should allow the user to click only one checkbox on the listview. If there are 2 checkboxes in 2 rows and then when the 2nd checkbox is checked, the first checkbox "Checked" should be cleared. When the 2nd checkbox is clicked the 1st checkbox "check" to be cleared.

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

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.

Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _

View 5 RepliesI'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 RepliesI 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?
Do I really have to go through all this just to find out what item has been selected in a ListView?
