问题 I'm trying to bind two <Run> s inside a TextBlock as shown in the snippet below. But I'm getting an XamlParseException . Basically I'm trying to achieve this format: CodeNum: LongDescription If the below code is doomed to fail what other alternatives do I have? <TextBlock> <Run FontWeight="Bold" Text="{Binding CodeNum}"/> <Run FontWeight="Bold" Text=": "/> <Run Text="{Binding LongDescription}"/> </TextBlock> 回答1: I'm guessing that either LongDescription or CodeNumis is a read-only property

问题 I would like to create a custom DataGrid column (or a DataGridCell style), ideally in XAML, and use it multiple times without any code duplication. It should contain multiple different controls, each accessing a different property of the data object. There seem to be two ways of doing this: DataGridTemplateColumn with a custom CellTemplate (see an example here) custom DataGridCell style (something like this or this) Both of these solutions suffer from the same issue. When specifying the

问题 In my WPF project, I have a dll that contains several WPF UserControls. I would like, in runtime, to be able to check a parameter in the database (already implemented) and according to that parameter (which is a string) to be able to load a specific UserControl to my View. The UserControl is actually a Canvas, so it basically just places the correct Canvas on the View according to the database entry.

My mind tends towards some sort of binding property

问题 I'm using Visual Studio, C#, XAML, WPF. In my program I have XAML buttons with white png icons. I want to have it so you can switch to a theme with black icons by choosing the theme from a ComboBox.

问题 I want to style the slider control so that the height of the draggable thumb is set to 8 pixels. What is the simplest way to do this in WPF? <Slider> <Slider.Style> <!-- which xaml here? --> </Slider.style> </Slider> 回答1: The Slider Control has many parts Thumb, RepeatButtons and a Track. It is one of those controls that have named elements, like PART_Track, referenced by the code-behind for it to work correctly. A good starting point is to use Blend to help you out.
