Hi Andy,

 I submitted a feature request for  an event to fire after LoadCustomization has completed.

  Can you attach your layout? - I'd like to see the customizations that are causing the Summaries to fail.

Yes, I need that event when layout is loaded added to xamDataGrid.

Othervise I don't know when to add SummaryDefenitions to my grid. I must do if after grid's layout is loaded. And I don't want to save SummaryDefinitions to the layout cos it would be too unflexible.

Why did you implement it to be async? Surely there must be a callback method..

Hi,

 Feature Request has been submitted.

 I did notice that the FieldLayouts PropertyChange event does fires after a LoadCustomization method is called. You could wire this event up and bypass the logic init using a global variable that you set during a LoadCustomization process.  You could key off of a certain property change to load your summary records.

 here a code snippet

load = false;

 
// xamDataGrid1.FieldLayoutInitializing += new EventHandler<Infragistics.Windows.DataPresenter.Events.FieldLayoutInitializingEventArgs>(xamDataGrid1_FieldLayoutInitializing);

 
xamDataGrid1.FieldLayouts[0].PropertyChanged += new PropertyChangedEventHandler(MainWindow_PropertyChanged); 
 

}

 
void MainWindow_PropertyChanged(object sender, PropertyChangedEventArgs
e)

{

//throw new NotImplementedException();

if
(load)

{

Dispatcher.BeginInvoke(ew Action (() =>

{

 MessageBox.Show(e.PropertyName);

}), null
);

The problem is that FieldLayout_PropertyChanged event is also fired multiple times whe I bind data to the grid. So there is still no way to deferentiate between data binding and layout loading events.

Unless there is a special property name which gets changed when layout is loaded. Do you that?

HI,

 Place your summary code inside of the Dispatcher after you call your  LoadCustomizations

 Dispatcher.BeginInvoke(ew Action (() =>

{

//add your summary data here

  }), null

 Sincerely,

Matt, thanks for your reply.

But it won't work. Here a sample code:

xamDataGrid1.DataSource = myDataView;

xamDataGrid1.LoadCustomizations();

After these two line of code you will be getting multiple PropertyChanged events for the Fieldayout. And there is no way to say when it was the layout loaded or loaded at all.

In your code sample the message box could popup just because of some data is bound to a DataGrid.

HI ,
 You could use a global variable and have it initialized to false and only turn it on when you call the LoadCustomizations.  Then when you can turn it off

 Here a code snippet

 void MainWindow_PropertyChanged(object sender, PropertyChangedEventArgs e)
        {
            //throw new NotImplementedException();
            if (load)
            {
                Dispatcher.BeginInvoke(new Action(() =>
                    {
                        MessageBox.Show(e.PropertyName);
                    }), null);
              
            }
        }

Sincerely,

 Matt
