Hi, I've been trying to create a listview and treeview with icons. You
would think it's a pretty straight forward task. API documentation
states you simply assign an ImageList - that's been populated either
using VS.NET (my method) or programatically .
I assigned the imagelist to the small icons in the listview.
Even VS.NET has been satisfied with what I'm doing as it shows the
listitems/treenodes with icons. As soon as I build/run however, all
icons are missing.
One thing to note is I had originally extended a standard list, added
the images using the extended class (using the very same listview) and
it worked. Unfortunately, a list isn't powerful enough for my
purposes.
I've spent 10 hours (prob more) trying to fix this. I've installed all
possible patches, examined my code line-by-line. Tried to reproduce
the .net API examples. Nothing.
Has anyone had a similar issue? If so - Please help... please? 3 12174
Hi,
Sounds really weird, the only thing that comes to my mind is that when you
use WinXP, you should call Application.DoE vents prior to calling
Application.Run (). You can find more on this in the "Applying Windows XP
Visual Styles to Windows Forms Applications" topic in MSDN.
To quote the article:
<quote>
Note If one of the controls on your form is an ImageList control, be sure
to include the following line of code before calling Application.Run ().
// C#
Application.DoE vents();

Your suggestion worked!
Of course, it's always something simple like that :| 25 hours on one
little problem and it comes down to 30 odd characters of text!
Once again, thank you. I honestly thought no one would know what the
problem was - let alone care.
Ian,
I am really glad my suggestion has worked! Also keep in mind that, on WinXP,
the format to which ImageLists are serialized when stored in resource files
is *different* to that on Win2K and earlier versions.

Hi All,
I am using the ImageList/ListView Components to display around 100 images
in C#.NET.
The issue i have is, some times i may need to display the thumbnail of size
more then 256x256 in ImageList.
But the ImageList Component supports only size upto 256x256.
What is the best way to handle this?

I want to have a TreeView that shows an image on some items, but not
all. Basically, if a certain condition is true, a caution icon is
placed next to the treeview item. The problem is that, by adding a
ImageList to the TreeView, the ImageIndex property of the items in the
TreeView defaults to 0. I could put a blank icon in the ImageList and
make it the 0 index image, however, this makes an ugly space.
Would I have to create my own...

Hi,
I have a problem for use of imagelist.
The problem is I have written a code which returns me the icons

After getting the icon for the file I am adding the icon to the
imagelist and then use its position to display the icon in the
listview.
