问题 I am trying to change background color of grid (with name "colorPlace") in my simple app (when I click on button). I tried (where red, green and blue are bytes): colorPlace.Background = new SolidColorBrush(Color.FromArgb(255, red, green, blue)); and: colorPlace.SetValue(BackgroundProperty, "#FFFFFFFF"); And all I just get is: An exception of type 'System.NullReferenceException' occurred in Project.DLL but was not handled in user code Any ideas how to do it? EDIT: Oh, I just find an solution -

问题 Can you please show how to set and save the background color of the viewport3D. Whenever I save no background is visible only model, I tried the grid but that gets everything in the grid? Any help will do? 回答1: Viewport3D doesn't have a Background property so you need something behind it. your approach using a Grid is right, you might want to use a Border to enforce the use of a single child. <Border Background="Green"> <Viewport3D Width="640.0" Height="480.0" > <ModelVisual3D/> </Viewport3D>

问题 I'm trying to draw lines between cells which are JLabel but fail to get their coordinates. The lines must follow a path from a startPoint to an endPoint. In my View class, the below code creates the grid: void createGrid(int rows, int cols) { MyMouseListener listener = new MyMouseListener(); setRows(rows); mainPanel.setLayout(new GridLayout(rows, cols, 1, 1)); mainPanel.setBorder(BorderFactory.createLineBorder(Color.BLACK)); mainPanel.setBackground(Color.DARK_GRAY); grid = new JLabel[rows]

问题 Using Kaxaml, resizing from the left works as expected. <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Grid> <Grid HorizontalAlignment="Left"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"></ColumnDefinition> <ColumnDefinition Width="Auto"></ColumnDefinition> <ColumnDefinition Width="Auto"></ColumnDefinition> </Grid.ColumnDefinitions> <GridSplitter Grid.Column="1" Width="5" Background="DarkGray"

问题 In my app I'm displaying some info about users in a listbox. I've got most of the stuff as I want, but the layout is bugging me a bit. It's made with grids, so that it'll re-size and fit portrait/landscape modes. However, I cannot get the layout to "fix itself"... let me try and explain with pictures: As you can see the numbers at the right side isn't aligned to the right edge of the screen. How do I achieve this? Landscape mode looks almost okay: Below is some of the XAML: <ListBox

问题 I'm trying to set a background for a grid control in WP7 silverlight, I need to do that programatically, not in the desighn. I tried something like: ContentPanel.Background = new BitmapImage(new Uri("Images\Backgrounds\with box\13.jpg", UriKind.Relative)); But of course, I got an error, because on the right hand we should have the type SolidColorBrush . is there a way to do that?

问题 I want to draw a multi-column UITableView like the picture below, which is different than a common Custom Cell. How do I do this? 回答1: Is it horizontally scrollable? It doesn't look so. If it's only vertically scrollable, use a regular UITableView. For each row, you use a UITableViewCell as usual. For each column, just use a UIButton or any widget that you like. In your screenshot, it looks like columns but there is no underlying concept of columns. You can easily create custom UITableView

问题 I have a GridLayout in my Xamarin.Forms App and I would like each element in the grid shown here: to be an instance of something like this: Where each element (brand, picture, price, seller etc.) is set by getting a value from an array and placing that value into the cell. For example, if I am only using the brand and the picture (in the form of strings) for now, and I have just retrieved data from my SQL database in the form of two lists: (pseudocode) brand = ["supreme","louisvuitton",
