Virtualization + Filter: Display selected rows correctly after a filter operation in a grid with checkbox column

Question

Hi,we use a grid with a checkbox column. The functionality that you can select, deselect rows and display that correctly, even after a filter operation, works fine. For loading a large amount of data, we need the virtualization functionality. But if we activate this functionality, the selected and deselected data are no longer displayed correctly after a filter operation - the indexes remain selected regardless of the data(see attachement). The first three rows should not be selected(AfterFilter.PNG). Is there any way from syncfusion side to handle this issue?Regards,FabianAttachment: FilterGrid_e69469b4.zip

Hi Andreas, 
 
Thanks for contacting Syncfusion support. 
 
Based on your query, we suspect that you have facing issue in Virtualization Grid with persist selection feature. i.e. The persistSelection feature is not working properly when we perform Grid actions like Filtering, Sorting etc., in the Virtualization Grid. We have considered “Persist Selection misbehaves while Sorting with virtualization” as an improvement feature and logged an improvement feature task for this requirement. We will include this feature in any of our upcoming release. 
You can now track the current status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this feedback link:

We appreciate your patience until then.
