Selected ListViewItem is the wrong color (grey instead of blue)

[DotNetter]

I have a ListView with FullRowSelect=True. When I select an row (i.e. a ListViewItem) the selected row turns blue, as I'd expect.

Here's the problem: I need to set HideSelection=False. When I do that, the selected ListViewItem no longer is highlighted in blue, but rather in grey. This bugs me significantly.

How can I keep the "normal" blue highlighting while having HideSelection=False?

Thanks,
Dot

By default, when you move your focus to another control, the listview will highlight in grey for the selected item when HideSelection = False. This is default Windows behavior. I would recommend against cirumventing it as to not go against Windows standards, but if you must, then you can create a routine to actually change the background color yourself and leave HideSelection = True.

That's not what's happening...

When I click on a ListViewItem - and focus is right there - on the ListView and on that ListViewItem - it's grey, never blue...

Any ideas?

Thanks,
Dot

I've never seen this happen. Are you running the listview in Details view?

 

[DotNetter]

Yes

 

[RiverGuy]

Again, it's never behaved this way for me. Are you sure you are not setting a backcolor or have altered your system colors in your display properties?

 

[DotNetter]

No, I haven't.

Weirder: the highlighted ListViewItem is grey. When I click my (own) back button and then my (own) next button - which gets me back to that same ListView with the same item still selected, it's now blue! The code I call in the next button to get back there is:

lvwUsers.SelectedItems.Item(0).Focused = True

Does that provide any hints? I'm lost...

Thanks,

No it doesn't. I have experienced buggy behavior with the ListView, such when I set the forecolor to a color other than default, it will sometimes only change the color for the subitems other than 0, but if I click off of it and go back to it, it is fixed. It must be a bug in the way its set up, but I don't know what causes it.

 

[DotNetter]

I don't believe I changed the colors on the ListView: the ForeColor is set to WindowText and the BackColor is set to Window...

I recreated this problem with a form containing a listview and two buttons.

I added some columns and items, set HideSelection to False and FullRowSelect to True.

The code for the buttons:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
  ListView1.Focus()
End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
  ListView1.SelectedItems(0).Focused = True
End Sub

Now when I start the form and select an item in the listview it will show up blue. When I use the tab key to lose focus from the listview and click Button1 the listview will again receive focus and the line is blue. If I however would press Button2 (your method) the line stays grayed out.

The problem is thus your way of giving the listview the focus. You should set the focus on the entire listview, not the item.

Ruffnekk,

Thanks very much for your testing and your reply - sorry about the delay in getting back to this thread - I got sidetracked...

I removed the one

ListView1.SelectedItems(0).Focused = True

that I had in my code and replaced it with

ListView1.Focus()

but it still is highlighting in grey, exactly as I described before...

Any other ideas?

Thanks!
Dot

Doesn't this have to do with your system colours? If you use Windows XP and use the Silver coloured theme it will never be blue, because that theme defines the highlighted colour as a grey. Also, if you use custom colour schemes that might be the bottleneck.

I don't use a custom color scheme. Also, sometimes it's grey and sometimes it's blue...

You've probably tried this already, but sometimes when things go inexplicably wrong ...

Delete the ListView
Add a new ListView


Hope this helps.
