SuspendLayout during adding filter-predicates?

Question

Hi.Can You help me please? I have GridDataControl with a lot of records and I want to add filter-predicates to GridDataVisibleColumn.Filters. But everytime I call gridDataVisibleColumn.Filters.Add(new FilterPredicate(...)), grid is doing lot of actions and it takes lot of time. I know, it's possible, because when I saw Your BasicFilteringDemo and in the column I choose "Select All", it's quick.Thanks.Regards,Juraj

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,
