Silverlight 3 RIA controls and how they load
If you have started playing with the RIA controls for Silverlight, one thing that you will need to understand is that when you get a DomainContext and call one of the load commands, that it does this async.
So if you do something like:
var context = new TestDomainContext();
context.LoadProducts();
foreach (Product p in context.Products)
{
myComboBox.Items.Add(p.ProductName);
}
You will get nothing put into your ComboBox. You need to hook up to the Loaded event and when that fires, then you can load up your ComboBox:
var context = new TestDomainContext();
context.LoadProducts();
context.Loaded += new EventHandler
<System.Windows.Ria.Data.LoadedDataEventArgs>
(context_Loaded);
void context_Loaded(object sender,
System.Windows.Ria.Data.LoadedDataEventArgs e)
{
var context = sender as TestDomainContext;
foreach (Product p in context.Products)
{
myComboBox.Items.Add(p.ProductName);
}
}
Just wanted to get that out there in case anyone else runs into that issue.
