Hi Daniel,
Thank you for your interest in Syncfusion products.
If want to iterate the rows through the events such as QueryCellInfo in GridControl, then you can use the PrepareViewStyleInfo which goes through the elements of the GridDataBoundGrid as row index and column index as the argument.
Please refer the sample attached in the below location:
