In the example below I have a ListBox with dozens of font names in it. I would have thought it would automatically have a vertical scrollbar on it so that you can select ANY font, not just the first ones in teh list, but it doesn't. So I added a "ScrollViewer" and that puts a "scrollbar area" on the right but there is no scrollbar in t...

In the below code, the ListBox gets filled with the names of the colors from the XML file, but those names strangely do not appear in the TextBox. However, if you bind the textbox to the static "lbColor2", those names do appear. So what could be different about the names when they come from the XML source which makes them not get passe...

How can I have put some kind of AJAXy spinning graphic in the ListBox until the data is there? Here is the code: <Window x:Class="WpfApplication5.Window1" xmlns="http://schemas.microsoft.com/winfx...

I am writing a winforms app in which a user selects an item from a listbox and edits some data that forms part of an associated object. The edits are then applied from the object list to an underlying file. In ASP.Net assigning a different system value to a list item than the display text the user sees is trivial. In a winforms app you ...
I have a different style for the items in my listbox on MouseOver which gives a slight zoom effect. This works nicely, but since the ZIndex is set in the order items are added to the ListBox, the zoomed item will be drawn behind the next item. I would like to set it so that the zoomed item is on top. I've tried creating a MouseOver even...
Is there an ItemActivated event (like in Windows Forms) in the WPF ListBox or ComboBox controls? I can't see one. It seems crazy for there not to be some event doing the same kind of thing - so does it just go by another name? If not, is there another easy way to do it? I've seen various blog posts about this but they all seem to involv...
Hi everybody! I want to draw some listview items disabled and would like to mimic the appearance of a disabled standard Windows listbox. Which colors does it use? I can't find anything in my reference chart :-) or with Google. Edit: Shortly after posting the obvious occurred to me - it seems to be COLOR_GRAYTEXT. ...
I'm subclassing the standard ListBox control. I get notified of changes to any of the elements added to the list. The task is to update the text shown by the ListBox for the changing element. I'm aware that i could just remove the changed element and add it again, but this seems not preferable for obvious reasons. ...
If I use a custom panel to layout my ListBoxItems, the ListBox won't respect their combined Height (it does respect their combined Width though) - even when my ArrangeOverride returns a size that surrounds all the items. Setting the ListBox's Height explicitly makes everything work, but I want it to work that out for itself! Has anyo...
