I'm using an ObjectDataSource with a GridView with an OnObjectCreated handler on the code-behind. If I programmatically change a child control value on the GridView, the entire control gets databound a second time in the same request (as shown by the OnObjectCreated handler), which I don't want. This happens on the initial page GET reque...
In my App class, I have a Collection of objects, like this: (the Collection is in the App class because i need to have access to it application-wide in different windows, etc.) public partial class App : Application { public ObservableCollection<Person> Persons { get; set; } public App() { Persons = new ObservableCollection<Person...
I'm sure I am missing some of the basics here so please bear with me. I have a two objects, a SalesOrder and a SalesOrderLineItem. The lineitems are kept in an Observablecollection<SalesOrderLineItem> of SalesOrder, and if I add line items my databound listView knows about the new items. Now where I am having a problem is here: The Sal...

I've got a xaml TabControl and on one page, there are 3 RadioButtons each bound to a different property on the selected value of an adjacent ListView. After switching between selected items in the ListView, my radio buttons seem to forget they're bound and don't refresh. So watching it in the debugger, when I switch to a new selected it...

I have a Form (Compact Framework, actually) with a few fields, a date and a string, among other things. Both TextBox controls are bound to properties in a BindindSource. The BindindSource has a DataSet as its DataSource property, and the DataMember is a table in a SQL CE database. When I want to add a new row, I call bindingSource.AddN...
I am binding a WPF ComboBox to a nullable property of type MyEnum? (where MyEnum is an enumerated type) I am programmatically populating the ComboBox items like this: // The enum type being bound to enum MyEnum { Yes, No } // Helper class for representing combobox listitems // (a combination of display string and value) class ComboIt...
I have a form with a date value in a TextBox control. The form uses data binding with a BindingSource against a DataSet and a SQL 2005 CE database. Where do I control the formatting of the date? Nowhere in the properties along the way did I see a possibility to strip out the time part, for instance. I could of course do it in the databa...
Ok so this is kind of urgent at this point. I have a large-scale AIR application that is pigging out left and right, and by massive amounts of trace statements and generating my own stack traces (useful for debugging), I have found that each combo-box is getting it's lookup from the LookupManager class multiple times, equating to about 3...
Hi! I have a problem when binding a command in a context menu on a usercontrol that is on a tab page. The first time I use the menu (right-click on the tab) it works great, but if I switch tab the command will use the databound instance that was used the first time. If I put a button that is bound to the command in the usercontrol it wo...

Here's my code: // In MeasureOverride(Size) m_inputWidth = 0.0; Size elemSize = new Size(double.PositiveInfinity, RowHeight); MapElementView ruler = new MapElementView(); // Measure inputs for...
I've got an instance of an object bound in XAML. It's got a method that will return to me a list of other objects (based on the property value I pass this method, it will return all the objects with that property value). <ObjectDataProvider ObjectInstance="_this.DataContext" MethodName="GetListByCategory" x:Key="List"> <ObjectDa...

A sample of the XML: <Buttons> <ButtonSettings ID="Bye"> <Text lang="NL">Doei!</Text> <Text lang="DE">Tsusch!</Text> <Tex...
To my understanding, binding errors are displayed only during debug mode in Visual Studio's Output window. However, I want to know about broken bindings when the user runs my app, and I want to notify him that something is not working quite right. Is there a way to handle binding exceptions from code, when the datacontext is set, and so...

I have yet to find a "nice" way to do two way databinding in .Net. The one thing I don't like for example in the present asp.net two way databinding is doing the binding in the aspx page is no compile time checking, ie: <asp:TextBox ID="TitleTextBox" runat="server" Text='<%# Bind("Title_oops_spelled_wrong") %>'>...
