Adding a default item when binding to the ItemSource

[Justin]

I have a form where I do create/edit

The items I want to edit are in a RadComboBox which I bind to the ItemSource.

How can I get a default value of "-- Create New--" into the combobox after it gets bound?

Ok, about 5 min after I posted this I had an idea.

I populate my combobox with a WCF Service.  On the "Completed" event, I just do something like this:

e.Result.Insert(0, new MyClass(){ Name = "-- Create New --", Id = -1 });
ComboBox.ItemsSource = e.Result;
ComboBox.SelectedIndex = 0;

Seems to work well...

That's good thinking, thanks for posting your solution, I'm definitely going to need to use that in the very near future!

Hello,

I would suggest you to use the same approach you already used for the Create new option. I guess you didn't apply it, because the collection you receive is read-only. If this is the case you could create a brand new collection and insert all the data from the data table you want to display and also add the default option.

Hope this helps.

All the best,
