Hi Juraj,
Sorry for the inconvenience
caused. We have checked with your requirement, you are trying to add the filter
predicates of the GridDataVisibleColumn.Filters in the code behind but please
note, the filter predicates which you are adding in the code behind and the predicates created during run time
while using Excel-Like filter checkbox will not synchronize with each other. We
are implementing this feature for upcoming release which will available by next
month first week. We will update you once this feature is successfully
implemented.
In order to uncheck the
SelectAll checkbox, you have clear the Filters of the respective
GridDataVisibleColumn. In order to check the SelectAll check box, you have retrieve
the distinct values of that particular visible column and then you have to
create separate filter predicates for each values. But, for other cases it will
not synchronize with each other.
Please let us know if you
have any queries.
Thanks,
Rajasekar
