Alex --

I tried the following:

1. ) I embedded the the Event Trigger XAML (from your post) within a Style Element in the Window.Resources area that is being applied to all igDP:DataRecordPresenter object.

This does not seem change anything.

2.) I embedded the Event Trigger XAML (from your post) within a <igDP:XamDataGrid.Triggers> Element within the <igDP:XamDataGrid> declaration.  This time I got a compile error because the compiler couldn't figure out what I meant by the "IsExpanded" property.

When I handle the InitializeRecords event in the code-behind I set the IsEnabled property of DataPresenter.Record.

How do I get access to DataPresenter.Record in the XAML file?

Is there some way to get here from <igDP:XamDataGrid.Records> or

<igDP:XamDataGrid.ViewSettings>?

I had a similar experience with this same project.  Following the example in the Help I was handling the FieldLayoutInitialized event so I could Collapse the Visibility of the field that was used as the grouping criteria.

I saw that since I was already looking at the first FieldLayout in the XAML all I had to do was declare a Field object with the Name of the field to be collapsed.  Thus, I no longer needed to do this in the code-behind file.

I'm looking to do something similar to this for the DataPresenter.Record.IsExpanded, but I can't figure out how to get access to the DataPresenter object in XAML.

Dave,

Test this and let me know if that works for you:

<EventTrigger RoutedEvent="igDP:XamDataGrid.Loaded">

                    <BeginStoryboard>

                        <Storyboard>

                            <BooleanAnimationUsingKeyFrames Storyboard.TargetProperty="IsExpanded" Duration="0:0:0">

                                <BooleanAnimationUsingKeyFrames.KeyFrames>

                                    <BooleanKeyFrameCollection>

                                        <DiscreteBooleanKeyFrame Value="True"/>

                                    </BooleanKeyFrameCollection>

                                </BooleanAnimationUsingKeyFrames.KeyFrames>

                            </BooleanAnimationUsingKeyFrames>

                        </Storyboard>

                    </BeginStoryboard>

                </EventTrigger>

Regards,

Alex.

This was my attempt to implement your first suggestion.

I can make the Data Grid  come up Expanded if I handle the InitializeRecord event in the code-behind file and set the Record.IsEpanded property to True.

What I'm looking for is a way to do this in XAML, so I can keep my code-behind file as simple as possible.

(I'm using Dependency Injection with the M-V-VM pattern to allow unit tests to be as complete as possible.)

I can't figure out how to get at the correct instances of the Record classes from XAML without handling an event.

This may be more of a WPF question rather then a specifically Infragistics question.

I am not quite sure what you are trying to achieve with this setter:

<Setter Property="IsEnabled" Value="True" />

True is the default value of that property.

Am I missing something?

Alex.
