hi,
I have a problem displaying icons at the right colour depthin a
ListView.
I've made an icon file, (using IconWorkshop 5), it has 3 icons within
it. A 32x32 32bpp XP style icon, a 32x32 32bpp non-xp icon (no
transparency), and a 16x16 version.
I add these icons to an ImageList, which is then assigned to the
LargeImageList property of the ListView.
The list view dislays the XP-style icon even on Win2k. I would like to
be able to tell it to display the non-xp version of the icon.
I've tried setting the "ColorDepth " property of the ListView- but it
seems to make no difference.
In Windows File Explorer they display correctly (ie, on win2k it shows
the non-xp icon).
It also seems to slightly distort the image - (it seems to take the XP
icon, and convert its colour depth)- , compared to the Windows
Explorer version.
Any ideas? I'm getting desparate.
Thanks,
David.

Hi scoobydoo,
As i remeber, if you want to change color depth of images in
ImageList, then you should set ImageList's ColorDepth before
you add these images.
AFAIK ListView does not have any property like "ColorDepth ".

Hi David,
Only simple solution i see is:
1. Create a second ImageList with wanted ColorDepth
2. Copy all images from first into a second one.
I didn't test it, so if there will be any proplems
then let me know. Personaly i don't know how it will
work with TransparentColo r?
Cheers!
Marcin Hi,
Thank you for your reply.
I meant the ColorDepth property of the ImageList, not the List View, sorry.
The icons are embeeded resources, and are loaded :
Icon myIcon = new Icon(GetType(), "myico.ico" );
I set the ImageSize, ColorDepth and Transparency properties of the Imagelist
before adding the icon to it.
Any clues,
TIA,
David

Hello,
I am trying to create a ListView object on my form with two columns. A
small, 32 pixel wide column on the left for holding images, and a column
that takes up the rest of the ListView on the right for storing text.
My question is this: how do I store images in this first column? I see all
kinds of support for small icon images and large icon images, but those are
for views that I do not want. Is there any way to do this?

Hi All
I used listview and tried to update it by using Addrange.
When the number of items is less, it works fine.. But I
need to update nearly 200,000 items and it hangs. Also i
need to add images to listview also(This is to list all
the items in my inbox, and want to give the user the feel
of outlook).
Since it hangs for even 1000 items in the inbox, i tried
to shift to virtual listview. But virtual listview

Can anybody tell me how to define which icon is displayed in a listView?
I'm writing in c#.
My implementation ALWAYS uses the windows XP version of the icon within the
..ico file. I would like it to use a different color-depth-version, but cannot
find a way to specify this.
I've tried setting the ColorDepth property of the LargeImageList, but it
appears to make no difference.
