Imagine the situation you open a WPF Popup (e.g. through ButtonClick ). You have a ListBox directly in the Popup with some items, so you have to be able to scroll. Imagine that this is your Custom Control and it's located in the ScrollViewer . Now if you move with your mouse outside from the Popup surface and scroll, what happens? You scroll up and down but with the Popup opened ! And that's the problem. The question is, how to detect from inside the Control, that some other unknown Parent Control in the VisualTree has started to scroll ? and consecutively set IsDropDownOpen = false ? We can

I'm getting started with Leanback support for our app. As per UI requirements I need to add multiple list rows corresponding to each header, it's exactly like what Youtube App does on Android TV. Default ListRowPresenter seems to be rendering only one list row and its header. Is there any presenter that supports multiple list rows? I'm thinking on the lines creating a custom presenter with RowsFragment embedded in each item, correct me if my approach is wrong. The Leanback team has recently added in support for multiple ListRow s for one HeaderItem in version 24.0.0 of the library. It allows

I'm developing my first WPF custom control and I'm facing some problems, here's a simplified version of the code I'm currently using: using System.Windows; using System.Windows.Controls; namespace MyControls { [TemplatePart(Name = "PART_Button", Type = typeof (Button))] public class MyControl : Control { public static readonly DependencyProperty ContentProperty = DependencyProperty.Register("Content", typeof (object), typeof (MyControl), new PropertyMetadata(null, OnLabelPropertyChanged)); private Button _buttonElement; public object Content { get { return this.GetValue(LabelProperty); } set {

I have a DatePicker custom control that I am trying to add to toolbox. The name of the file is BasicFrame.WebControls.BasicDatePicker.dll and I go through the procedure of right click in Toolbox > Choose Items and then selecting the file after browsing to it under .NET Framework components. I however get this error message: There are no components in that can be placed on toolbox Why do I get this message and how can I resolve it? MikeT Have you checked the visibility of the custom classes? If you haven't declared them as public they will default to internal and hence aren't exposed to Visual

I am porting an application from iPhone to BlackBerry. BlackBerry apps tend not to look as polished as iPhone, but naturally, I would like to maintain as much polish as I can, without breaking any important UI conventions. Are there any UI components that can help with this? NB. I am planning to follow all important UI conventions. For example, I will use the BlackBerry Menu instead of a tab bar for providing access to help and some other advanced options. Links Make BlackBerry UI Components Look Like iPhone Components Maksym Gontar You can extend blackberry controls with custom drawing , or

I am searching for Volume Slider that looks and behave just like VLC's slider. I found the following post about how to style the slider: Volume Slider CustomControl but I also want the same behavior... What is the difference between the behaviors: When you click on the slider [at the WPF] and move the mouse on the slider area (while mouse button still being hold) it should move the slider also to the position of the mouse on the slider. I couldn't find how to do it.. maybe I should use something different than Slider? Thanks for the help! There is a property on the slider called

I'm currently attempting to create a custom control out of a DataGridTemplateColumn that will be reused across many of our applications. I'm running into some issues getting a dependency property on the custom control to bind and raise the property changed notification correctly. I currently have the control inheriting from DataGridTemplateColumn the xaml looks like this: <DataGridTemplateColumn x:Class="Controls.DataGridDateColumn" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <DataGridTemplateColumn.CellTemplate>

In the image below there is an area, which has an unknown (custom) class. That's not a Grid or a Table. I need to be able: to select Rows in this area to grab a Value from each cell The problem is since that's not a common type element - I have no idea how to google this problem or solve it myself. So far the code is following: Process[] proc = Process.GetProcessesByName("programname"); AutomationElement window = AutomationElement.FromHandle(proc [0].MainWindowHandle); PropertyCondition xEllist2 = new PropertyCondition(AutomationElement.ClassNameProperty, "CustomListClass",
