Hi, I have a view of my data being fed by a viewmodel, but I'm having some issues with comboboxes. The xaml looks like this: <ComboBox Grid.Row="4" Grid.Column="1" Margin="2,2,10,2" ItemsSource="{Binding TrialParentValues, UpdateSourceTrigger=PropertyChanged, Mode=OneWay}" SelectedItem="{...
In our domain, we override the ToString method on all our domain types. However, when returning those domain objects in response to a Silverlight service request, the functionality of ToString is lost. ToString() just returns the namespace description of the object as it is imported from the service. My guess is that the domain prox...

I have a VM and a model and I want to ensure a user does not enter alpha char's into multiple textbox's bound to doubles (or ints). I'm running into 3 issues 1) When I use the ValidationRule the method returns a 'Valid...
I have a DataGrid that has event handlers bound to SortCommand and PageIndexChanged. How can I determine if those event handlers are about to be called, say on page_load? These events will fire just fine after page_load, but I'd like to know at page_load if they are to be fired. ...
How can I have a property grid update automatically when the object in its SelectedObject property changes? I've tried implementing INotifyPropertyChanged in my class but the property grid does not actually show the new propertyies of the object in the background until I click on it. I've tried subscribing to the PropertyChanged event ...

Hi Im using a List<Patient> object as the data source to a data grid view. I need to use concatenation of two string properties in the Patient class as the value of a single text box column.

Is there a way to use the existing WPF BooleanToVisibilityConverter converter but have False values convert to Hidden instead of the default Collapsed, or should I just write my own? I'm on a project where it's tremendous overhead to do something simple like this (shared stuff goes into a separate solution, and the rebuild/checkin/merge...
How can I make such UI: 1) ListBox with items. 2) Detail information about selected item. 3) When you change any item in details information, the selected item in the list becomes bold... 4) ... until you push "Save" button and all changes go to the database. For example, for Binding to the list I use Object with String Name property an...
Is there some way to avoid this. I have a lot of classes that are bound to DataGridViews and they are just simple collection of properties with default getter and setter. So these classes are very simple. Now I need to implement INotifyPropertyChanged interface for them which will increase the amount of code a lot. Is there any class tha...
Hi I have an Combobox which is poplated with data that is time sensitive. My setup is a bit hard to explain so lets assume that the Combobox has a itemtemplate containing a textblock. The textblock is databound to a property returning DateTime.Now, I would like to rebind the value of the textblock (not the whole combobox). Is there a way...
Hi, I'm still fairly new to silverlight, so hopefully this is an elementary question: I have a polyline whose 'Points' (type: PointsCollection) property is bound to a PointsCollection public member, Pts, in my view model class. When I add/remove points from ViewModel.Pts, the polyline redraws correctly without any problem. However, if...
