Does anyone know how to programmatically bind a property to a function that isn't a getter? IE: I have a function that returns a translated string based on the identifier you pass it. How do I do this in AS3 rather than MXML? (reason being - I have a dynamic layout that I render based on XML and so have create and add all children progr...
I'm relatively new to DataBinding and just reading into it. What I want to do is the following: I have a StackPanel with a number of child controls: <StackPanel Orientation="Horizontal"> <TextBox x:Name="textbox1" Width="100">1</TextBox> <TextBox x:Name="textbox2" Width="100">2</TextBox> <Tex...
Following from my question on binding in general, I'd like to ask for help on the following scenario. I have a collection of objects (imageFileData) displayed via a DataTemplate in a ListBox control. The control is bound to an ObservableCollection. Both the collection and the template are defined within my application xaml and xaml.cs...
Ok, So I have been stalled in my latest non-work project, trying to use WPF. I am just frankly annoyed at databinding. I thought it was supposed to make things simpler by binding data directly to the UI. But the more I learn about having to implement INotifyPropertyChanged to get things to notify the UI if they changed, seems to make...
I have a set of data objects that I am using for databinding that implement the INotifyPropertyChanged interface and I'm trying to figure out what to do with properties of complex type. If I have something like class C { private string text; public string Text { get { return text; } set { if(Text != value) { text = value;...
When I bind a TextBox control to a string property of a object using two way binding, it works fine - as long as the user moves off the control before he closes the browser window/tab. But what about the user who makes a change to the contents of a text box then closes the window expecting the data to have been saved? While it is possi...
Hi, I've been having a problem binding a ListView to an Object using LINQ. It's best explained with a testcase I've created: C#: using System; using System.Collections.Generic; using System.Collections.ObjectModel; using System.Linq; using System.Windows; using System.Windows.Controls; namespace WpfApplication1 { public partial c...
I'm binding a control to an XmlDocument and using the "XPath" binding expression to output the data: <div class="Bio"><%# XPath("Biography") %></div> However, this returns the InnerText property of the "Biography" element, not the InnerXml. This means it strips all inner tags from it, which is not what I want. I looked through the X...
The MSDN walkthroughs provide a number of examples where you can drag a DataSource from the toolbox, run through some simple configuration steps, then drag a ListView onto the screen, point it at the DataSource, and hey - you've got full table editing. Now I'm trying to write my own DataSource class (a class that implements System.Web....
This piece of code <asp:DropDownList runat="server" ID="testdropdown" SelectedValue="2"> <asp:ListItem Text="1" Value="1"></asp:ListItem> <asp:ListItem Text="2" Value="2"></asp:ListItem> <asp:ListItem Text="3" Value="3"></asp:ListItem> </asp:DropDownList> yields this error: The 'SelectedValue' property cannot be set ...

The xaml looks like: <TextBox Name="_txtFirstName" Text="{Binding Path=Contact.FirstName, UpdateSourceTrigger=PropertyChanged}"/> This worked properly until I...
I am new to WPF so hopefully I phrased the question correctly. What I'd like to do is bind my <Image> to an image online. However, the image I would like to bind to changes depending on the state of the application. For example, if I wanted to bind to an Employee selected from a list, I'd retrieve a base URL from my App.config and append...

Preamble I'm asking this question because even though I've read through a lot of ListView resources, I'm still not 'getting' it. Background I have a bunch of Foo's that have a list of items associated with them (known as Bar), and I'm pulling them from the Data Access/Business Logic layer as Dictionary that holds a Foo and its associ...

I am currently working on a small N-Tier application in C# which uses Linq-to-Entities (SQL Express 2005 for the DB) and WPF and I am wondering what type of data collection my business logic layer should be supplying to the user interface. Are there downsides (performance, validation etc) to binding form objects like datagridviews to an...
