Hi Matt, of course I need more assitance here.

I need an event when async loading of grid's layout is complete.

When I load my grid I always restore its layout first. And then I need to add some custom logic, let say I want to add row summaries to the grid. But loading the layout whipes out my summaries.

Here is some psydo code:

xamDataGrid1.LoadCustomizations(layout);

xamDataGrid1.Records.Summaries.Add(....);

.....

few seconds later when lyout is loaded, the summaries are all empty becase there are not in the layout.

THanks.

HI,

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

 Dispatcher.BeginInvoke(ew Action (() =>

{

//add your summary data here

  }), null

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

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?
