Set background color for selected items in a ListBox

阅读更多关于 Set background color for selected items in a ListBox

问题 I cannot set the background color for the selected item on a list box. I don't want the alternating colors in this example. I put them in as a test and they work. Trigger IsSelected is firing as the fontweight goes to bold and the foreground goes to red. Setting highlight color brush to SteelBlue does not achieve the desired effect as it goes away when the ListBox loses focus. Red and bold does hold when the ListBox loses focus and is what I want. I want the background color to take and hold

Get Selected TreeViewItem Using MVVM

问题 So someone suggested using a WPF TreeView , and I thought: "Yeah, that seems like the right approach." Now, hours and hours later, I simply can't believe how difficult it has been to use this control. Through a bunch of research, I was able to get the TreeView` control working, but I simply cannot find the "proper" way to get the selected item to the view model. I do not need to set the selected item from code; I just need my view model to know which item the user selected. So far, I have

WPF TreeView: How to style selected items with rounded corners like in Explorer

阅读更多关于 WPF TreeView: How to style selected items with rounded corners like in Explorer

The selected item in a WPF TreeView has a dark blue background with "sharp" corners. That looks a bit dated today: I would like to change the background to look like in Explorer of Windows 7 (with/without focus): What I tried so far does not remove the original dark blue background but paints a rounded border on top of it so that you see the dark blue color at the edges and at the left side - ugly. Interestingly, when my version does not have the focus, it looks pretty OK: I would like to refrain from redefining the control template as shown here or here . I want to set the minimum required

阅读更多关于 Selecting a Textbox Item in a Listbox does not change the selected item of the listbox

I Have a wpf Listbox that display's a list of textboxes. When I click on the Textbox the Listbox selection does not change. I have to click next to the TextBox to select the listbox item. Is there some property I need to set for the Textbox to forward the click event to the Listbox? We use the following style to set a PreviewGotKeyboardFocus which handles all events of TextBox control and ComboBoxes and such: <ListView.ItemContainerStyle> <Style TargetType="ListViewItem"> <EventSetter Event="PreviewGotKeyboardFocus" Handler="SelectCurrentItem"/> </Style> </ListView.ItemContainerStyle> And then

How to databind SelectedItem of RibbonComboBox

阅读更多关于 How to databind SelectedItem of RibbonComboBox

问题 My question is basically this one. I thought it would help to provide some more information and code that makes it easier to reproduce the problem, though. Working with the Microsoft.Windows.Controls.Ribbon.RibbonComboBox from the RibbonControlsLibrary feels like walking through a big bog full of bugs, not something you do if you know a way around it. Anywho. The biggest problem I encountered was databinding my SelectedItem. The following is what I started with (after I found out about

问题 I have a ComboBox that has its ItemsSource bound to a static List<CustomSettings> of options. The ComboBox is part of a form which is bound to a CustomObject class, and one of the properties on that class is a CustomSettingProperty.

Using breakpoints I can see that it is calling the get;
