Hello Prakash,

First thing that comes up in my mind is to handle the RecordExpanding event and check the fieldlayout and other conditions that you might have and cancel it if needed.

The other thing is control the ExpansionIndicatorDisplayMode of the fieldlayout in the FieldLayoutInitializing event:

For example:

void xamDataGrid1_FieldLayoutInitializing(object sender, Infragistics.Windows.DataPresenter.Events.FieldLayoutInitializingEventArgs e)

        {

            if (xamDataGrid1.FieldLayouts.Count > 1)

                e.FieldLayout.Settings.ExpansionIndicatorDisplayMode = ExpansionIndicatorDisplayMode.Never;

        }

Hope this helps.

i have attached an image of my grid.

My Scenario is Table B has 5 Child Tables and

in the xaml i have made those 5 tables as fields in my table B Fieldlayout.

Even though if for a B record there no  related record with all child tables it shows the expander for all the 5 child tables.

I wanted to disable the field loyouts or the expander for the child table layout which does not contain data each time.

I think if you see the image you could understand the scenario.

Thanks

Prakash

HI Alex,

Thanks for the answer

I tried the way you suggested me and it works for me now.

But only thing is when i hide some field layouts it create's some empty space below each parent record.

I have attached the output image.

And also in your example how can you disable the header of the  field layout which do not have records.( in your example it is Emplyees)

Thanks

Prakash
