Hello,

I need to use the FilterFieldItemControl disconnected from the usual containers, just like this:

<Grid>

<igPivotPrim:FilterFieldItemControl Content="{Binding ElementName=UserControl_Edition, Path=MyFilter}"/>

</Grid>

The Property Filter is an "IFilterViewModel" created like this:

IFilterViewModel filterViewModel = this.dataSource.CreateFilterViewModel(designatedHierarchy);

this.MyFilter=filterViewModel;

The problem is when i click the OK button i get the following exception:

Exception Type: 'NullReferenceException'. Message: 'Object reference not set to an instance of an object.'. at: Infragistics.Controls.Grids.Primitives.FilterFieldItemControl.OK()

What am i doing wrong?

Regards,
Ângelo.

Hello Stefan,

I assumed that was the problem and already implemented a very tricky workaround.

However i find it very strange that is impossible to override the command handling.

Regards,

Ângelo.

Hello Ângelo,

Thank you for your post. I have been looking into it and I can say that FilterFieldItemControl is not meant to be used outside the XamPivotGrid, since the commands, that are executed when clicking on OK and Cancel button, are related to the grid and this is why you get an exception when you use the control outside the XamPivotGrid.
