Expand the GroupByRecordPresenter
posted

How does one make the GroupByRecordPresenter expand so it displays its child nodes the first time it becomes visible?  I attempted to do it through a style but it didn't have any affect:

 

<Style TargetType="{x:Type igDP:GroupByRecordPresenter}">

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

</Style>

    Hi,

    Setting  the IsExpanded property in the GroupByRecordPresenter style will not work probably because
    of the timing issues. In any case, you should use the InitializeRecord event to expand group-by records.


    public void xamDataGridName_InitializeRecord( object sender, InitializeRecordEventArgs e )
     {
         if(e.Record is GroupByRecord)
            {
                 e.Record.IsExpanded = true;
            }
     }


    Best Regards,
    Yanko
