Programmatically Trigger A Listview Sort?
Jun 18, 2011
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 a program that gets some information from the user and updates the database.I also have two DataGridView, OpenOrders and ItemsInOrder When the user click on a cell in the OpenOrders a CellChange event is triggered and it updates the ItemsInOrder grid view. Now after I update the quantity of a product i want to cause that CellChange event to trigger again in order to refresh the ItemsInOrder grid view.

Currently my ListView sorts items by image.index. So 0 is at the top, then 1, 2 and so on. Think of it as an IRC chat room nick list. Ops at top then the rest are sorted alphabetically

I have a main form that has a dynamically generated treeview and also a panel control. Depending on the selection made within the treeview the panel docks 1 of three diffrent usercontrols which are full sub forms(done for ease of modifing design of sub form rather than layering panels on top of panels).Upon button click withing usercontrol i wish to trigger event within main form.For example delete button wich then triggers to remove current selected node from treeview. code for 1 of three diffrent user controls
Dim ctrlQ As New QuoteUC(TrViewQuotation.SelectedNode)
PnlSubFormDock1.Controls.Add(ctrlQ)
Code for delete button for which i need to raise event.
If MsgBox("Are you sure you wish to delete this customer ?", vbYesNo, "Delete Record") = vbYes Then
Deletecustomer(n)
End If

i have to develop a software for motorola mc9090 that reads barcodes and rfids simultaneously, so i need to catch two different triggers: the one on the keyboard for barcodes and the other in the backside for rfids.the problem is that i didn't find any sample that illustrates how to set the trigger to read only barcodes, i found something on emdk 2.5 samples that shows how to set the trigger to read rfids but nothing for barcodes. So when i press any trigger the barcode reader is always enabled with rfids reader.Does exist a way to manage them with separated triggers?

In a gridview, the sorting event you can do a
With CType(sender, GridView)
.DataSource = Os
.DataBind()
End With

Using Microsoft Visual Studio 2010 Ultimate - VB.Net
I'm writing an application where as many of other applications fulfill the requirements to be as an app , having it's statistics schema. Thus I made a form where I have a combox(of query category), a textbox(as searchfield), two datetimepickers(from and to) a listview and a button to fire the event with functions in it. I'm all set except for a minor issue I've encountered during my very first experiments with ListView control. Thus far I didn't know that VB users are stuck with that control's property options (whereas DataGridView has way too many), especially when it came to Column reordering/s. With the simple but not satisfying property Sort I couldn't find a proper solution to my issue.
when I click on of the columns in the listview to do a Number/Date/Text reordering (descending>ascending, via-verse). Not to forget to mention there a limited number of columns most likely 2-4 max.
The listview control has lvResults name and has for now columns inserted as "Country" and the other for subitems "Total Spent".
One e.g. of the values inserted to it is like this :
[Code].....
If pressed on Total Spent, should reorder from highest to the lowest number and via-versa. If pressed on Country should reorder from A to Z or via-versa.

I'm trying to sort my listview using a custom icomparer. I have to sort numbers, strings, dates, and currency.
Here's the code to sort:
compareResult = ObjectCompare.Compare(listviewX.SubItems(ColumnToSort).Text, listviewY.SubItems(ColumnToSort).Text)
The problem is it sorts numbers wrong, such as:
10
2
3
instead of
2
3
10

I'm trying to set something up where the user can sort each column by clicking on the header... i've looked at some other examples and they seem pretty longwinded..so far i have the below...
VB
Private Sub resultsListView_ColumnClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ColumnClickEventArgs) Handles resultsListView.ColumnClick
Dim oldsort As SortOrder
[code]....
which works fine... but only for the first column in the list view.Is there a way of specifying which column to sort based on which is clicked?

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 support a .Net 2.0 Windows application that has a custom listview control to allow for greater flexibility. I am not allowed to bring this to a newer version of the gramework until next year. We are moving from XP to Windows 7, and we have identified an issue with how the column sort image (up/down arrow) is drawn to the listview. Currently in XP, the image is drawn to the right of the column's text. However, in Windows 7, I am getting Access Violation Exceptions. Now, I know that the error is with the improper handling of memory using the unmanaged code as shown below. I am looking for a method to mimic what we have below in a safe manner using managed code.

I'm using VB 2008 and windows vista. I'm using a listview in my application.(view=details) I assign an image list to listview.smallimagelist. when user try to sort the listview by clicking the column header i use the imageindex property to set an icon for that column header, this works fine. When user clicks another column to sort the listview by that, I use listview.columns(PreviousColumnIndex).imageindex=-1 to remove the sort order icon from the previously selected columnheader, but it does not remove the picture from the previous columnheader. How should I remove the icon(picture) from the previous column header?

After a long time searching, I am still facing an issue with my listview column header I am trying to add a sort indicator (a small 16x16 arrow, next to the column title - looks quite good).
- My listview is in Ownerdraw mode for : Items & Subitems for a couple of reasons
- So far, I was letting the system do the job for the header (e.drawdefault = true)
I managed to add very easily the arrow using the e.graphics class, right after the e.drawdefault=true, and it is actually working good.
print01.gif
(Sub ColumnHeader OwnerDraw)
e.DrawDefault = True
e.Graphics.DrawImage(My.Resources.fleche_v2_16x16, 34, 2, 16, 16)
As you can see, I'm simply using a resource, and am forcing it to 16x16 with a custom location x=34 pixels y=2pixels My issue comes with the following :
(Sub ColumnHeader OwnerDraw)
e.DrawDefault = True
e.Graphics.DrawImage(My.Resources.fleche_v2_16x16, (e.Bounds.X + 34), 2, 16, 16)
The arrow wont draw Of course the sort indicator will sometime be on the 2nd column etc.. That's why I need to use the column header's bounds.I can already hear you saying : if you do not owner draw, you can't..But why is it working with a static location (, 34, 2, 16, 16) ans not starting from another static location (e.bounds.x) How can I fix that ? I cant find previous issues similar to that one over the internet.
Points of interest :
- I tryed to load the int value e.bounds.x into a variable before, using that instead of e.bounds.x but it's all the same.
- Using the imagelist is not an option, As you can tell from the screenshot, I am already using images for headers.. the sort indicator is coming as another image
- Using ">" or "<" in the header's text is not an option either........ (sorry pal It does not look good at all..)
- Drawing the header totally in owner draw mode would be an option, but it looks quite hard to do (need to manage the "rounded" header style of the system, the mouse over - small yellow line rounded on the sides in WinXp, the click effect....).

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.
