Ok, so I've got this Visual Studio 2008 Project I was working with about a year ago perhaps. And this project had a datagrid that was linked to an external database running on a server off the internet. Now, this databinding was all done using Visual Studio 2008's built in features. But how can I now change the binding to a different se...

So I am using ViewModels to pass data from/to the web forms in my MVC application, as seems to be recommended practice from what I have read. My question is what is the normal approach to then map the ViewModel into an actual domain entity? I'm guessing I should probably add a 'GetObject' method to my ViewModels so I have something lik...

I want it to be easy to modify in case we need to add or remove information parsed. And make sure that it's easy to update this information from my Parser class to the actual Forms or User Controls.

I would like to make a (very lightweight) 2-way binding datastore. Values must be accessed via names. I was thinking of using 2 arrays: public class MyBindingDatastore{ public string[] _names = new string[]{"Field1", "Field2", "Field3"} public object[] _values = new object[]{ DateTime.Now, "MyValue", 1} } First array is used t...
Using SilverLight, one can bind the value of a control to a property from a datacontext. That's fine. It is possible to use StringFormat along with the binding declaration to format the value. Again, that's cool! However, I can't find a way to have the binding with some operation done to it before it gets displayed. I know I can code a...
Hi, I'm working on an application that has a large domain - i.e. Customers, SalesOrder, Suppliers, Products, Stocks etc. - and have discovered that the WinForms data binding is a little too restrictive for what I need. Is there a useful design pattern for setting up the populating of forms and updating of the underlying data? Thanks ...

I've some simple code below that uses a ToggleButton.IsChecked property to set the Visibility of a TextBlock. It works fine. Since this doesn't quite fit in with my program's structure, I'm trying to bind the visibility of another TextBlock to a DependencyProperty of "this". It compiles fine, but it produces no effect. I'm doing some...

Hi, I'm binding an Image control to a value set at runtime, but I want to set the FallbackValue to a resource named "checkerboard.png". As Converters aren't applied to FallbackValues I need to use the Pack notation, which leaves me with the following XAML: <Image x:Name="imgButton" Height="{Binding Path=Height}" Width="{Bindi...
