Hi Issam,


Thank you for using Syncfusion products.


We have analyzed your query. We regret to inform you that, we cannot use the incremental loading feature with a listbox or similar controls. In the Incremental loading feature the incremental list is banded the ItemSource and the Incremental list is only supported in SfDataGrid only.


Please let us know if you have any queries.

Thank you,

Jai Ganesh S

Hi Issam,


Thank you for the update.


We have analyzed your query. We regret to inform you that we don’t consider the  feature request for Incremental Loading support with ListView because in Incremental Loading we have created the separate list internally in our source and bind as an ItemSource to SfDataGrid. And it is not possible to bind with other ItemsControl.


We have another control as SfDataPager, it is used to view the records by pages. We have created the sample with SfDataPager and ListView control and please find the sample from the below location,


Sample: http://www.syncfusion.com/downloads/support/directtrac/143001/ze/DataPagingDemo1155691439


Please let us know if you need further assistance.


Thank you,

Jai Ganesh S

Hi,

thanks for the sample, it could help in some situations,

but i  continue to blieve that a Data virtualization solution that can be used with layouts different than datagrid like presentations could be very usefull

the example of a listbox with a container that present the data on multiple columns is very common




anyway thanks again!
really appreciate .

Hi Issam,


Thank you for the update.


We have analyzed your query. We suspect that you want to use the Data Virtualization in SfDataGrid. We already have a sample for DataVirtualization in SfDatagrid by creating the records only for rows in the current view. Please find the sample from the below location,


Sample:

http://www.syncfusion.com/downloads/support/directtrac/142832/ze/DataVirtualization147268139


Note: In the above sample, we have set the ItemSource as VirtualizingCollectioView and it is not possible to bind this with other Items control.
