  • WPF - Two way binding use a user control...binding to object, not an element!

    - by Scott
    I created an object with a simple property with a default value. I then created a user control that has a text box in it. I set the datacontext of the user control to the object. The text box correctly shows the properties default value but I can't seem to update the property value when the user changes the text box value. I created a simple project to illustrate my code. Thanks for the help!! public partial class UserControl1 : UserControl { public UserControl1() { InitializeComponent(); } private string _titleValue; public string TitleValue { get { return _titleValue; } set { _titleValue = value; textBox1.Text = _titleValue; } } public static readonly DependencyProperty TitleValueProperty = DependencyProperty.Register( "TitleValue", typeof(string), typeof(UserControl1), new FrameworkPropertyMetadata(new PropertyChangedCallback(titleUpdated)) ); //Don't think I should need to do this!!! private static void titleUpdated(DependencyObject d, DependencyPropertyChangedEventArgs e) { ((UserControl1)d).TitleValue = (string)e.NewValue; } } <UserControl x:Class="WpfApplication1.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"> <Grid> <TextBox Height="23" HorizontalAlignment="Left" Margin="94,97,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" Text="{Binding Path=TitleValue, Mode=TwoWay}"/> </Grid> </UserControl> public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); var dummy = new DummyObject("This is my title."); userControl11.DataContext = dummy; } private void button1_Click(object sender, RoutedEventArgs e) { MessageBox.Show("The value is: " + ((DummyObject)userControl11.DataContext).Title); } } <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525" xmlns:my="clr-namespace:WpfApplication1"> <Grid> <my:UserControl1 HorizontalAlignment="Left" Margin="95,44,0,0" x:Name="userControl11" VerticalAlignment="Top" Height="191" Width="293" TitleValue="{Binding Path=Title, Mode=TwoWay}"/> <Button Content="Check Value" Height="23" HorizontalAlignment="Left" Margin="20,12,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" /> </Grid> </Window>

  • Change Iframe Content from Cached HTML?

    - by Yang
    Is there any way that I can change the content of iframe from a cached html string? I am not talking about iframe.Attribute["src"] = "url", but rather given a string of html and change the content. An ugly workaround might be saving the html into a file and change iframe src to it. Any other ways? Maybe javascript can help?

    - by Ben McCormack
    Let's say I have: public class Item { public string SKU {get; set; } public string Description {get; set; } } .... Is there a built-in method in .NET that will let me get the properties and values for variable i of type Item that might look like this: {SKU: "123-4556", Description: "Millennial Radio Classic"} I know that .ToString() can be overloaded to provide this functionaility, but I couldn't remember if this was already provided in .NET.

  • Java. Best procedure to de-serialize a Java generic object?

    - by Jake
    What is the best procedure for storing and retrieving, using native Java serialization, generic objects like ArrayList<String>? Edit: To clarify. When I serialize an object of type ArrayList<String> I'd like to de-serialize to the same type of object. However, I know of no way to cast back to this generic object without causing warnings.

  • Java: Is there a way to obtain the bytecode for a class at runtime?

    - by Adam Paynter
    In Java, is there a way (at runtime) to obtain the bytecode which defined a particular class? Put another way, is there a way to obtain the byte[] array passed to ClassLoader.defineClass(String name, byte[] b, int off, int len) when a particular class was loaded? I see that this method is declared final, so creating a custom ClassLoader to intercept class definitions seems out of the question. In the past, I have used the class's ClassLoader to obtain the bytecode via the getResourceAsStream(String) method, but I would prefer a more canonical solution.

  • OleDB Jet - Float issues in reading excel data

    - by Patrick
    When I read a sheet into a DataTable using the OleDbDataReader, floating point numbers loose their precision. I tried forcing OleDb to read the excel data as string, but although the data is now contained in a DataRow with each Column defined as System.String it looses precision (18.125 - 18.124962832). Any idea how to avoid this behaviour?

  • Read from file in eclipse

    - by Buzkie
    I'm trying to read from a text file to input data to my java program. However, eclipse continuosly gives me a Source not found error no matter where I put the file. I've made an additional sources folder in the project directory, the file in question is in both it and the bin file for the project and it still can't find it. I even put a copy of it on my desktop and tried pointing eclipse there when it asked me to browse for the source lookup path. No matter what I do it can't find the file. here's my code in case it's pertinent: System.out.println(System.getProperty("user.dir")); File file = new File("file.txt"); Scanner scanner = new Scanner(file); in addition, it says the user directory is the project directory and there is a copy there too. I have no clue what to do. Thanks, Alex after attempting the suggestion below and refreshing again, I was greeted by a host of errors.

  • Remove leading whitespaces using variable length lookbehind in RegExp

    - by Shizhidi
    Hello, I'm wondering if variable length lookbehind assertions are supported in JavaScript's RegExp engine? For example, I'm trying to match the string "variable length" in the string "[a lot of whitespaces and/or tabs]variable length lookbehind", and I have something like this but it does not go well in various RegExp testers: ^(?<=[ \t]+).+(?= lookbehind) If it's an illegal pattern, what would be a good workaround to it? Thanks!
