Hi Emilian,
Greetings from Syncfusion support.
By default, when perform search/filter action, the corresponding search/filter query will be applied in Grid’s DataSource. So now, each time when a data related operation is performed in Grid’s datasource then this filter/search query will be applied in the resultant data.
When modifying the cell value, Grid will refresh to reflect the modified changes. This refresh will include the already applied filter/search query in Grid along with the modified cell changes. This is our default architectural behavior of performing editing in a grid which has pre-applied filter/search query.
Please get back to us if you need further assistance.
Regards,
Renjith R
