First drag the "Group" column to group it. Then check the checkbox from the toolbar, everything is selected but when I try to unselect, nothing happend.
The checkbox from the toolbar should be checked but it not the case.
Can you help me to solve this problem?
Also, when there is enough data to scroll (ex:93) with the grouping and the checked all button checked, when I scroll the display is not correct (the checkboxes are unchecked) I suppose the issue is from the display because I need to click 2 times on the checkbox to refresh the display (uncheck then check).

Greetings from Syncfusion Support.
We have validated the provided sample. The ‘enableVirtualization’ feature is used to bind large number data in to Grid. The ‘enableVirtualization’ feature will load the data vertically based on the number of records in Grid. However, in your sample we found that you have used only two columns. So the ‘enableVirtualization’ property is not needed for your requirement. We suggest you to remove ‘enableVirtualization’ property in your sample.
Note : If you want to maintain the selection , you need to enable ‘persistSelection’ of selectionSettings of Grid . Also you need to enable isPrimaryKey in any one of your unique field of your Grid.
