I've already tried to set Focusable="False", bind to the LostFocus-event and set the focus on the window in code-behind but nothing worked. In the application it is important that nothing other than the containing Window can have focus so the space-bar pressing can be routed to a specific command. Problem now is, that when pressing space-bar, the canvas is opened again. However, when clicking outside the canvas closes as expected. When clicking the ToggleButton the canvas is shown and the user can pick the color he wants to. For the RadColorPicker, you will need to merge the following resources:Įxample 16 demonstrates how to merge the ResourceDictionaries so that they are applied globally for the entire application.I'm using the ColorPicker control from the Extended WPF Toolkit with some restrictions as I want the user to only have the ColorCanvas enabled. Merge the ResourceDictionaries with the namespace required for the controls that you are using from the theme assembly. You can see the different themes applied in the Theming examples from our WPF Controls Examples application. To change the theme, you can follow the steps below:Ĭhoose between the themes and add reference to the corresponding theme assembly (ex: 8.dll). This is applicable only for the controls in the scope in which the resources are merged. You can see how to apply a theme different than the default one in the Setting a Theme help article.Ĭhanging the theme using implicit styles will affect all controls that have styles defined in the merged resource dictionaries. The controls from our suite support different themes. If there is such a color this palette will be visible.ĪdditionalContent - can be used to add customized content under RadColorPicker control. IsRecentColorsActive - defines wether a customized color, not existing in the MainPalette, HeaderPalette, StandartPalette or RecentPalette should be added in the RecentColorsPaletteView. SelectedItem - should be used in MVVM scenarios and it holds the selected ViewModel - the DataContext of the selected RadColorPaletteViewItem. The behavior of this property mimics the behavior of the ItemsControl.DisplayMemberPath property. It is not applied to RecentPalette items.ĬolorPropertyPath - the control uses this path to find the property of type in the DataContext of the RadColorPaletteViewItems. PaletteItemsTemplate - Should be used in MVVM scenarios to get or set the ContentTemplate of the RadColorPaletteViewItems from the MainPalette, HeaderPalette, StandartPalette. Content property should not be used for this purpose IsDropDownOpen - Opens or closes the drop down content.ĭropDownPlacement - Sets the DropDownPlacement of the drop down contentĬontentTemplate - Should be used to define the custom Content of the RadColorPicker. Whenever a color is selected SelectedColorChanged event is raised.ĭropDownClosed Raised when the SplitButton is closed.ĭropDownOpening Raised when the SplitButton is about to be opened.ĭropDownOpened Raised when the SplitButton is opened.Ĭlick Raised when the left part of the SplitButton is clicked. SelectedColorChanged RadColorPicker has SelectedColor property which is of Color type and is used to store selected color value. RadColorPicker colorPicker = new RadColorPicker() Collection colors = new Collection() colors.Add(Colors.Red) colors.Add(Colors.Green) colors.Add(Colors.Blue) colorPicker.MainPaletteItemsSource = colors Dim colorPicker As New RadColorPicker() Dim colors1 As New Collection(Of Color)() colors1.Add(Colors.Red) colors1.Add(Colors.Green) colors1.Add(Colors.Blue) colorPicker.MainPaletteItemsSource = colors1
