I've replicated this in the infragistics sample> xamGrid> display>conditional formatting rules by adding
<ig:XamGrid.GroupBySettings><ig:GroupBySettings AllowGroupByArea="Top" IsGroupable="True" /></ig:XamGrid.GroupBySettings>
Then group by any column expand a group and try to ungroup.
An exception is thrown
Is there any way around it?
Which version of the tools are you using? I tested this in 19.1 with our Conditional Formatting Rules sample and everything works as expected.
we have the 2018.2 but the samples I have downloaded is "19.1.20191.84".
Just to make it clear have you had the group expanded and the conditionalcolumn visisble?
Ah, thanks for reminding me. Yes, I have now reproduced the behavior. I'll let our team know and transition this conversation to a private case for you.
I've logged the development issue as (# 264080) with our developers to investigate this further and will provide you with further updates regarding our investigation as they become available. You may now visit the case from the support activities section > In development tab from your account.
Let me know if you have any questions.
