Add & Remove Listview ColumnHeader Sort Indicator?
Oct 15, 2009
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....).

Does anyone have a trick to catch when the mouse is over a listview column header ? As you know there is no native handler that would fire such event...
I have build a small routine that will be able to tell over which column the mouse actually is, the problem remains in which event to put it..

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 semicolon delimited string (e.g. an EMail Address List returned from a database or a textbox). How do I separate the string into an array, sort, and remove duplicates? The code below works to separate the string and sort the results, but doesn't remove the duplicates. I could probably then loop through the array and copy to a new array to eliminate the duplicates, but there must be a better way to do this using the VB.Net Array, String, and Collections handling classes.
Dim s As
String =
"Test; Test8;Test1;Test2;Test3; Test8;Test4;Test5; Test6"

What I am trying to do is sort a datagridview and remove a row from its sorted position to the 1st row.
The problem I am experiencing is as follows:
in the source below, when the code runs "MeanRow" is populated with what is required. As soon as Rows.Remove() executes, the MeanRow datarow is lost. Why would this be if I'm declaring a new variable and simply setting it?
Code:
MeanRow = r
TabGrid(dgv.Name).Datatable.Rows.Remove(r)
Code:
Private Sub dgv_Sorted(ByVal sender As Object, ByVal e As EventArgs)
Dim MeanRow As DataRow
[Code].....

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

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 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.
