Inherit the Listview Control and Repaint it

1 New Member
Inherit the Listview Control with Visual Basic ?

I have decided do inherit the Listview control some days ago to change some painting things to make the .net Listview look like the explorer's Listview. I am very new on doing those things like painting and also have not much practise with inheriting , so I got some problems while I tried to change the Control to that Listview I like.

Here are my Questions :

- Can I run a method if there is a item or column added , delete etc ? I did't find an event , but perhaps there is an other way I don't know about ?

- Can I decide if a subitem , which is delivered by DrawSubItem in detailview , is the first subitem which represent the listviewitem ?

- Can I inherit the ColumnCollectio n , Columnitem , ListviewitemCol lection and the Listviewitem etc Class alter them and make my inherited Listview work with them ?

Not so important things :

- How can I make o transparent look on a picture or overlay it with a color ?
- How can I get the values which shows me how much I have scrolled with the bars , and how can I set a new value to those values ?

Thanks for helping me out :)

Hi all, I have a VB.NET app which displays some data in a "Details" view of a ListView control. The code to populate the list is run in the Form_Load handler. When I run the Form,, all worked fine. Then, I added a 3rd party controls (2 buttons) to the form. Now when I run the form, the ListView Control is not visible. If I press the down arrow key, the list appears.

Hello Everyone. Does anyone knows how to create a new property for an user control that inherits a list view? The property should be a boolean value set to each clumn that is created in the listview. Property "ALLOWEDIT", when I set this property to TRUE, then it runs a sub, if not, it does nothing Any ideas? Thank you!!!

Hello, I'm trying to prevent a listView from repainting when I change group assignments for the items. Let's assume I have two groups with 100 items in each and moves 100 items from group A to group B, then the listView will repaint itself a lot, slowing down the operation and flickering (can be solved by listView.Visible = false; but it doesn't speed it up, i.e. the listView still repaints itself). There are the listView.BeginUpdate() and...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.
