AddNewDataItem event in XBAP

[Datafyer]

I have a WPF application which calls a dialog using the ShowDialog method and then sets the e.NewObject of the GridView event to the newly created row. Everything works very well, however I am attempting to change the ShowDialog calls to remove the synchronous actions. This is to get the code working in an XBap environment and to get it closer to Silverlight if a port is needed.

I am however baffled as to how to do this without blocking the UI thread to wait for the dialog information.

This is basically what I am doing now:

RadWindow NewWindow = new RadWindow();

NewWindow.ShowDialog();
e.NewObject = NewWindow.NewRow;

This is what I would like to do

RadWindow NewWindow = new RadWindow();

NewWindow.Closed += delegate
{
  e.NewObject = NewWindow.NewRow;
};

NewWindow.Show();

Hello Patrick,

 


Since you open your window as a normal window through calling the Show() method the UI behind this window will be still active and responsible to the end user.
I have prepared sample project illustrating how you may achieve a similar scenario to yours.
Please have a look at it and let me know how it corresponds to your custom needs.

What is the difference behind the scenes between adding an item by setting e.NewObject and by adding it directly to the bound list?
