Indication for isNull/isNotNull in simple datagrid filter (#1127)

mvoxland · web-flow · commit 313ee50bf212 · 2023-08-28T10:26:22.000+03:00
Added an Indication for when a datagrid (in simple mode)'s filter operator is set to either "is null" or "is not null". Before there was no way to see that any filters were applied until the popup was opened.
