Hey all, I've noticed that if I have a style setup for a treeview, and a different one setup for the treeviewitem, it gets overridden once I put the item in the tree. Does anyone have suggestions for how to control the style of each treeviewitem individually while mantaining a default style that is applied to the whole treeview? Basically I want to make the text of my treeviewitem red depending on a data field in the item. Otherwise I want it to be black. Thanks
DataTemplateSelector is not in Silverlight. Try below link

Thanks, turns out it was TreeViewItem.Style CAN be set to an ItemContainerStyle if you use the objects as references.

I am making a style for gridview in WPF which consists of several parts, currently I am stuck with the column headers part
I made a style for GridViewColumnHeader but now I need a style for its container
is there a part similar to "DataGridColumnHeadersPresenter" which is a wrapper for all of the columns?
Any help where to find the parts of the control? I want to find the name of that part and the default template for it.
Thank you
Another reason why Snoop is very good.
You get Snoop to identify the element your looking for
Guess it's GridViewHeaderRowPresenter what your looking for.
I have seen this post: WPF ComboBox: background color when disabled
and some others...
But This solution causes me some problems. All I want is to make the textBox gray, and the ComboBoxItems gray and not selectable. I don't want to recreate all the style as the control won't work properly on both XP and seven. I don't want to choose one style for both, but I want XP style for XP and seven style for seven.
Is there a way to set the style so I can change the Background of the ComboBoxItems when the comboBox is Readonly?
Thanks in advance!
Update: It seems that the Drop down popup should be restyled instead. I got to find how.
I finally found my answer at many places on the web, pieces by pieces. The ComboBox style is composed of other controls. The PopUp is the one that interests me. It is not public, so I can't modify it as I want. It would have been interesting to define a style for my popup and to replace the original popup by it, but it is not accessible, so... I attempted to make a template that inherits from the template of the original ComboBox, but that is not possible neither. It won't accept inheritance for some good reasons How to Inherit a Control Template. So the template must be remade totally or not. The other option would be to make my own control that inherits from combobox and that changes the items to gray and not selectable when the combobox is readonly (into the code), but this is not a good idea in my situation. No solution for me. I will have to stick with the whole template redifinition. I hope this post will help someone in some way!
I want to change the display behavior of the selected item(s) in a WPF Listview. Specifically, I want to retain the custom textblock foreground colors that I've applied and apply a border around the item.
I am able to alter SystemColors.HighlightBrushKey and ControlBrushKey to change the background color of the selected item, but I don't know how to get it to stop changing the font color or use a border instead. I've tried manipulating the control template and have also searched Google for examples of how to do this, without success.
yeah, looks like you have to go through the pain of using ControlTemplates.
Good news is that via using Expression Blend, you can get current ControlTemplate for ListView and tweak the bit that you need and use that as your default ControlTemplate.
How can i add different items with either background/foreground color different in WPF listbox?
You can can create a DataTemplete, set it to ListBox.ItemTemplate and use DataTrigger to change the display of the items.
ListBox has some very annoying behaviors that make styling it using data template difficult - in this blog post you will find the list of workarounds.
You may use an AlternationCount property, more info provided by this link
Or you can add to your objs binded to a listbox Background and Foreground properties and bind them in a DataTemplate of ListBox.ItemTemplate and change them in code however you like, properties must update themselves on every changing.
After tearing my hair out with this one (and your particular usecase might differ from mine) I found the WPF Toolkit's DataGrid cured all my needs.

I did it with a listbox in Blend inside of the ItemTemplate by creating a leftBorder and a right Border that are in the same space. The leftBorder is defined with cornerRadius 10,0,0,10 and the right with cornerRadius 0,10,10,0. I then set them both to opacity 0 (you can use visibility if you prefer) and set a ChangePropertyAction on both of thier loaded events conditional on the first and last item in your list.
That is the bad part, I did need to do it conditional on the items in your list but you could define another property and set that to first and last or create multiple templates that you set if there are no more items in the list from the control (not in the template).
If you think this may be interesting to you, let me know and I will post on my blog as well as try to make a couple of adjustments for your situation. I am not sure how to upload a project to here.
