Hi,
today i updated a project from 10.2.20102.2174 to 2207.
In my window I have several views in a XamDockManager.In one view I have a XamDataGrid which has a FieldLayout with a SummaryDefinition.Since the update I get a System.NullReferenceException when I try to open the view with an empty datasource.
The stacktrace end's with:
bei Infragistics.Windows.DataPresenter.GridViewPanelFlat.ArrangeHelper(UIElement visualChildElement, Dictionary`2 headerRecordMap, Boolean orientationIsVertical, Boolean isReverseLayoutForBottomFixed, Double extentUsedByLastItem, Double clipExtent, Size arrangeSize, Rect& arrangeRect, Double& recordIndent)
bei Infragistics.Windows.DataPresenter.GridViewPanelFlat.ArrangeOverride(Size finalSize)
The whole stacktrace is attached.
When I loaded the Infragistics Sourcecode, Visual Studio points to the file DataPresenter\GridViewPanelFlat.cs and the following line where headerRecordMap is NULL:
// JJD 1/24/11 - TFS63831// Make sure the header is removed from the map so it// doesn't get arranged out of viewheaderRecordMap.Remove(attachedToRecord);
Removing the SummaryDefinition from my FieldLayout avoids the exception but since it worked in 2174 it seems to be a bug.
Hi Matt,
the only thing missing in your sample was a key in the FieldLayout.Adding "Key="{x:Type app:Person}"" brings the NullReferenceException.
I've attached the modified sample.
Sincerely,
Bastian
