Change (or disable) selection color of listview [SOLVED partially]

a)Keep selection visible (with blue color, not gray, this is the problem with HideSelection) always

That's by design; whatever is focused is drawn in the "selected" color. That way I can (as a user) visually differentiate between the ListView that's focused (and will react to keyboard-input) and which won't. If both were using blue, it would imply that both have the input-focus. That's not possible in Windows, since there can only be one active control with input-focus. There's no "neat" way to do this. Why no owner-drawing btw?

b)Remember selected objects, but do not show the selection at all (because if the selection is visible, than the custom back/fore color are not visible), so I can "mimic" the selection by setting a custom back/fore color to the items.

Remembering selected objects can be done by adding them to a generic list, whenever you select one. Sounds like you want to replace the default multiselect by your own version?

Hello, I know this is possible because I seen it in action somewhere. I do not want to use owner draw, because I would have to implement tons of things, and I still want the list to look exactly like in windows (with the theme from windows). Still waiting for some suggestions. Thanks!

I'm not sure I understand your question fully, but I think you can set the Enabled Property to true and the Readonly property to true also. Apologies in advance if I have misunderstood your question.

Create your own list view and your own list view items. This is the easiest way to get the results you desire. In fact, it would have taken less than 4 hours, I bet.

Yup, it's possible :)

You want non-standard behavior, and that has to be implemented somewhere. Owner-drawing might sound like overkill, especially if you've been looking at examples that draw a lot manually. The example on MSDN[^] looks rather short and might do the trick.

Make sure you're using the SystemColors[^] when drawing.

This is a very basic solution, but here it is anyway:

private List selections = new List();
private bool dontChange = false;

private void listView1_SelectedIndexChanged(object sender, EventArgs e)
{
if (!dontChange)
{
dontChange = !dontChange;
int selectedIndex = listView2.SelectedIndices[0];

    listView1.SelectedIndices.Clear();

    //check if we're deselecting/selecting
    if (selections.Contains(selectedIndex))
    {
        selections.Remove(selectedIndex);
        listView1.Items\[selectedIndex\].BackColor = Color.White;
    }
    else
    {
        selections.Add(selectedIndex);
        listView1.Items\[selectedIndex\].BackColor = Color.Blue;
    }
}
else
{
    dontChange = !dontChange;
}

}

of course this only works if you're selecting one item at a time. If you're doing an extended selection (meaning using Ctrl or Shift to select items) it wouldn't work because when you click the first time, it will add the item, then when you click the second time, it tries to make all of the items selected, which would deselect the first item. You'd have to include some key checking to see if Ctrl or Shift was down.

Hello, I tried something like you said, before posting on this forum, but I don't think it's going to work. Now the problem is when selecting multiple items (by dragging). It can work only with 1 item, but if you have multiple items, and remove one item at a time from the SelectedIndices, it will call the event again and again. Don't know exactly how to explain. Thanks anyways

Hello, Thanks for the suggestion, I was trying to avoid this...

[sodevrom]

Hi, I don't think you understand exactly what I want. I simply want to view the selection in blue always (with multiple items), even if the listview has no focus. In a normal case, when the listivew loses focus, the selection turns gray, and you can't see it good.

[sodevrom]

Just a quick thought. The easiest way for this to work would be to "overwrite" the SystemColors . If it's possible to change the unfocused selection color form gray to blue, all my issues would have been solved...

You could write your own control? Create a user control and add a panel with with background and add labels one below the other, you can provide a property that allows to set the background of the labels. Add some internal logic to maintain selection, colors, text, indexes, etc... Should be less then 4 hours to get you going.
