Hi lorryl,
Greetings from Syncfusion support.
Query: What is the "check" field in the grid.dataSource ? Seems it's value is wrong.
By default grid dataSource will have the data which is initialized through dataSource property. Using checkbox selection will not add any additional field to the Grid dataSource. So we suspect that checked field is already present in the dataSource provided to the Grid.
Query:When I checked any record, the data' "Selected" or "check" value not change.
We would like to inform you that checkbox column used only for selecting purpose. So it cannot be used with field value. Also While selecting/unselecting the row will not change the value in the grid dataSource.
Please let us know, if you need further assistance.
Regards,
Manivel
