Group Expansion

[Jayesh Roshan]

Hi

I have 50 thousand records in my grid. When I expand it after grouping it takes a long time to load.

Please help as soon as possible.

Thanks

Hello Jayesh,

Generally you get some performance issues when the GridView is grouped, because the data virtualization is off. When the virtualization is used, then we are aware of the visible items only. That is way we cannot group and keep the virtualization at the same time.

Do you still have the same number is you reduce the number of items in the grid?

Kind regards,

Hi Didie

When I use virtualization then if I select a group it will only select those rows which are currently visibile others are remain unselected. We can't reduce grid items.

Please provide some other solution.

Thanks
