Need Help for CheckBox in DetailsView
Ozgur,
I am happy with your proposal.
But now I need help. I am in the process to integrate the proposed CheckBox
into the DetailsView. So far that was easier than expected. However...
For the thumnails I grab the checkbox location for each item in the
ItemListView.HitTest() using
Point location = layoutManager.GetCheckBoxLocation(bounds);
this.Items[index].CheckBoxLocation = location;
I am struggling to get the Y-co-ordinate for each row to code something
similar like above. Have I overseen something, or do I need to code the
whole Row.Location stuff or is the HitTest() the wrong place ?
BTW - I need the this.Items[index].CheckBoxLocation to check if the MouseUp
coordinates are within the CheckBox rectangle.

Collection for checked items
Now that we have item checkboxes, we need an !ImageListView.!CheckedItems
property to iterate over checked items.

Scroll bars does scroll by integral item height
* Posted by tonyt on CP *
When in details view, the control does not scroll by the
correct LargeChange amount, and results in only a portion
of the first visible item shown. By convention, the top of
the first visible item's bounds should be at the top of the
control's content bounds.
I think the problem is that the ScrollBar's LargeChange
value is not correctly set to be a multiple of the item
height.
From: ImageListViewLayoutManager.cs:
// Current line for detail view:
mImageListView.vScrollBar.LargeChange = mItemAreaBounds.Height;
// This corrects the issue:
mImageListView.vScrollBar.LargeChange =
mItemSize.Height * ( mItemAreaBounds.Height / mItemSize.Height );

AllowDuplicateFileNames = false doesn't work

windows explorer) again and again to the imagelisteview-area, although
AllowDuplicateFileNames = false.

Issue30 Follow-up GetFileIcon() BackColor
Thanks for implementing Issue30 GetFileIcon() and using the icon as
fallback to the thumbnail generation routine.
GetFileIcon() provides transparent alpha channel images. The 5.2 standard
fills the background color for thumbnails with white color. That is oK for
"normal" thumbnail images. However, for the GetFileIcon() icons I would
prefer a transparent background especially if the control background color
is changed to darker colors.
Proposed simple solution:
class Utility
{
...
internal static Image ThumbnailFromFile(string filename, Size size,
UseEmbeddedThumbnails useEmbeddedThumbnails, Color backColor)
...
// flag whether background color shall be cleared
// false = do not clear background for GetFileIcon()
// true = clear background for all other thumbnails
bool clearBackColor = true;
// Get the shell icon if the source file is not an image file
if (source == null)
{
try
{
bool large = false;
if (size.Width > 32 || size.Height > 32)
large = true;
source = GetFileIcon(filename, large);
clearBackColor = false; // << modified
}
catch
{
if (source != null)
source.Dispose();
source = null;
}
}
// If all failed, return null.
if (source == null) return null;
// Create the thumbnail
try
{
Size scaled = GetSizedImageBounds(source, size);
thumb = new Bitmap(source, scaled.Width, scaled.Height);
using (Graphics g = Graphics.FromImage(thumb))
{
g.PixelOffsetMode = PixelOffsetMode.None;
g.InterpolationMode = InterpolationMode.HighQualityBicubic;
if (clearBackColor) // << modified
g.Clear(backColor);
g.DrawImage(source, 0, 0, scaled.Width, scaled.Height);
}
}

ImagListViewItems properties
Any chance to get some of the properties belonging to the
ImageListViewItem writeable?
I specifically mean those properties like: FileSize, FNumber, Aperture ...
The reason is that i saved those to a database where i earlier pick them
from the file. But when i now read the image from the database i dont have
access to file on disk. When i read from database and want to:
Manina......ImageListViewItem.FileSize = "from database" i get the message
that its just readable.
Some thing to fix ?

ItemClick bug
* Posted by Kevin via email *
I have implemented a right-click context menu at the item level. I have
found that if the initial click on an item is a right-click it works
perfectly, but only once! if the first click is a left-click, for any
subsequent right-clicks after any initial click , the itemclick event will no
longer fire on a right-click for that image. once I move to another image
and come back, it seems to reset, but again, only for the initial right-
click, then nada.

Use VisualStyleRenderer for hovered state
* Posted by tonyt on CP *
One other suggestion is to use VisualStyleRenderer for
drawing the highlighting (for both hover and selected
items), if available on the current system.
// Your current code that draws the highlighting
// for the hovered item:
if ((state & ItemState.Hovered) != ItemState.None)
{
using( Brush bHovered = new LinearGradientBrush( bounds,
Color.FromArgb( 8, SystemColors.Highlight ),
Color.FromArgb( 32, SystemColors.Highlight ),
LinearGradientMode.Vertical ) )
{
Utility.FillRoundedRectangle( g, bHovered, bounds,
( mImageListView.View == View.Details ? 2 : 4 ) );
}
}
// Revised to use VisualStyleRenderer (if supported):
if ((state & ItemState.Hovered) != ItemState.None)
{
VisualStyleRenderer renderer =
new VisualStyleRenderer(
VisualStyleElement.Button.PushButton.Normal );
renderer.SetParameters( "BrowserTabBar::Menu", 14, 2 );
renderer.DrawBackground( g, bounds, bounds );
}

ctrl selection bug
*Posted by fredzhu on CP*
Add many images(>20)
hold ctrl key
select images one by one
well, when we select 5 - 10 , the previous selection was cleared.
The reason is when we move mouse a little, it start to do drag and drop
don't start drag when we hold ctrl or shift key, or don't start drag if it's
still move in himself.

Aggressive caching
* Posted by fredzhu on CP *
I means, when I add 50 images and only could view 20 images in the
ImageListView
It seems ImageListView cached 20 images and then stop caching.
If you scroll down to view other 30 images, it start to cache those 30
images....
But why not keep caching another 30 images even we only could view parts of
them at first?
In this case, 5 mins later, we don't need to wait for thumbnail when we
scroll down.

Drag drop error with InsertInternal
What steps will reproduce the problem?
1. Create 2 ImageListView (left and right)
2. Add two or some images to left one
3. Drag and drop images from left one to right one.
4. Remove all images in left one
5. Now we want to drag and drop images from right one to left one but can
not.
What is the expected output? What do you see instead?
I think images would be added to right listview but nothings is added.
What version of the product are you using? On what operating system?
I've used the latest version 3.3 with Windows 7, Visual Studio 2008 SP1
Please provide any additional information below.
I've investigated and found an ArgumentOutOfRangeException has been thrown
at mImageListView.Items.InsertInternal(index, item) in DragDrop method of
class ImageListViewNavigationManager. I think there's something wrong with
DropToRight make index is greater than number of items. My solution is try
insert again like below:
do
{
try
{
mImageListView.Items.InsertInternal(index, item);
break;
}
catch (Exception ex)
{
Debug.Print("EXCEPTION when insert item into " +
mImageListView.Name + " - COUNT: "
+ mImageListView.Items.Count + ", INSERT POS: " + index + ",
EXCEPTION: " + ex.Message);
}
// Decrease position
index--;
} while (index >= 0);

Properties ImageListViewItem
Ozgur,

used in a PropertyGrid, I suggest to group them and reverse the Browsable()
settings. Enclosed my proposal:

There may or may not be any difference performance-wise. This needs to be
tested.

Is there a way to get the context menu to pass the selected item.
Is there a easy way in a context menu to pass the selected item that was
used in the context menu selection.
I need to get a value out of the item selected for a delete to a database.
The index is in the text property of the item.

Mono support
The control builds successfully on Mono with a few glitches:
* Mono doesn't like when control's Text property is set to null.
* The ControlCollection (Controls property) is created after the control's
constructor, meaning the child scroll bars need to be added somewhere else.
* The P/Invoke call to get the file type does not work in Mono. This needs
to be replaced with something suitable for the Linux platform. The Linux
specific call needs to be hidden from the Windows build with something like
this:
public bool IsMono()
{
return Type.GetType("Mono.Runtime") != null;
}

Focus and keyboard navigation
*Posted by XChrome on CP:*
found some little bugs (tested with default (Vista-)Style)
1. When another control gets the focus - for example a treeview - and you
make a right-click with your mouse over an item in the imageviewlist, the
item-background becomes gray (no focus), instead blue, as usual. A right-
click on an item should set the focus to the imageviewlist as well as left-
click.
2. If an item is selected but another control is clicked the item-
background becomes gray - just like windows explorer. Thats okay. But if
you hover over the gray item with your mouse, the item-background becomes
an ugly gray+bluehover colormix. In Windows-Explorer on Vista an item
becomes the dark blue color - like selected (with focus) + hover. On
mouseleave its gray again. Should be fixed, too.
And now some suggestions for improvement:
3. The "Focus rectangle"-Drawing should only appear when more than one item
is selected via Shift/Ctrl+Mouseclick (see 4.+5.)
4. I see you have a Shift+Mouseclick function to select items. That should
not work with right-click - thats only for context-menu. Please make a test
with Windows Explorer
(works just the same under Windows XP as it does under Windows Vista)
- If you hold down the shiftkey, the focus rectangle appears and you can
make a left-click to select some additional items.
- If you still hold the shiftkey, and make a right-click over the selected
items, the context-menu appears.
- If you still hold the shiftkey, and make a right-click over another item,
the selected items lose the focus and the other item is selected
- If you still hold the shiftkey, and make a right-click somewhere else in
the imageviewlist, all selected items are losing the focus.
5. Can you please add a Ctrl+Mouseclick function for selecting multiple
items?
- Same right-click proporties as above

Using a context menu to get items:
I'm sorry I didn't get back to you on this issue sooner but I wanted to
research how its supposed to be done. The way I think that the control
should work is that you should be able to get the last item selected with a
context menu with:
ContextMenuStrip.SourceControl
Unfortunatly the control doesn't set a value for it. It is nothing.
If not, I have to set a global var to hold the select item till I get to it
in event down stream of the itemclick event.

Renderers should check the thumbnail size before drawing
What steps will reproduce the problem?
1. Add some virtual items
2. Supply virtual item images larger than the thumbnail size.
3. Rendered thumbnails will not be resized down.

Pimp-up Colors 4-All
Ozgur,
I like the Renderer and all Views. There is one missing bit, get custom
colors into the game. Enclosed my proposal.
Introduce a new class ImageListViewColor with static members Default, Noir,
etc.
Replace inline color settings with ImageListViewColor properties.
Add ImageListViewColor Colors property to ImageListView
That's it in short, attached the complete source code and two screenshots
using the default renderer with ImageListViewColor.Noir().
If you want to consider it for your standard code let me know, then I'll do
the last tweaks in the Default Renderer since I am not 100% happy with the
details view.

Overriding drag and drop for database connections
In using this control with my database app I need to handle the drag drop
event with out having the controls code exeute. It's easy just to blow away
the code in the drag drop event in ImageListViewNavigationManager for the
moment but was wondering about a long term plan for overriding drag and
drop and other (like hover) events to tailor this control. Do you have any
thoughts on how I should do this to be keep as close to any long range
plans you have for this control?
I can get the event with the current version of course in my code but the
controls events still execute.

CheckBox to ImageListViewItem
Ozgur,
This enhancement provides an option to include a CheckBox to the
ImageListViewItem and is a significant addition to the guts of your
control.
This option becomes handy if you would like to check several items
for further batch processing. Regard this as an alternative to
mouse select, which has the downside that selections disappear
when user does not press shift or control on mouse click.
This implementation allows to toggle check marks for a single item
or
mouse select several items, click on a checkbox of a selected item
and all other selected items will have the toggled check mark.
New features:
=============
ImageListView()
---------------
Properties:
bool ShowCheckBox whether to show checkbox
ContentAlignment CheckBoxAlign position checkbox
int CheckBoxPadding checkbox padding all
Events:
OnItemCheckBoxClick
Methods:
void CheckAll() Marks all items as checked.
void ClearChecked() Marks all items as unchecked.
void InverseChecked() Inverses all items check mark.
ImageListViewItem()
-------------------
Properties:
bool Checked value whether the item is checked
Please note, attached screenshot includes the proposed FileIcon property as
proposed in Issue39 (which I marked by mistake as defect).

Animated GIFS
*Posted by XChrome on CP*
Is there a way to support animated gifs? With static images like jpg, non-
animated gif, png everything works fine, but every animated gif throws an
error. Maybe you could use the ImageAnimator.CanAnimate (on gif-extensions
only) to check, if the images has frames and extract the first frame for the
thumbnail.

Update hovered item on mouse wheel
* Posted by tonyt on CP *
I noticed one thing it does very well, something that even
the Windows Common Control ListView has a problem with, is
that with hover highlighting, when the mouse wheel is used
to scroll the control, the hovered item is not updated until
the mouse moves (the problem in the CommCtrls ListView is
only an issue with hot-tracking enabled).
You seem to have addressed that problem nicely, except that
there seems to be a long delay before the hover highlighting
is changed to the new hovered item just after a mouse wheel
scroll. Are you using a timer for that?

ShowFileIcon property
For those who like it fancy, introduce a property whether to display the
file icon.
The proposed solution displays the file icon in thumbnails and details view:
class ImageListView
{
private bool mShowFileIcon;
/// <summary>
/// Gets or sets whether to display the file icon.
/// </summary>
[Category("Appearance"), Description("Gets or sets whether to display the
file icon."), DefaultValue(true)]
public bool ShowFileIcon
{
get { return mShowFileIcon; }
set { mShowFileIcon = value; }
}
public ImageListView()
{
...
mShowFileIcon = true;
}
class ImageListViewRenderer
public virtual void DrawItem
{
...
if (mImageListView.ShowFileIcon)
g.DrawImage(Utility.GetFileIcon(item.FileName, false), bounds.Right - 18,
bounds.Top + 2);
// Focus rectangle
...
}
