Hi,
Please make sure that you are not using DataBind() to bind the grid. Performing complex grid operations such as Inserting, Deleting, Updating, Hierarchy relations, Grouping, Exporting, Paging, Sorting, Filtering, etc. require accommodating appropriate database operations. Therefore, we suggest you to avoid Simple Databinding and strongly recommend the use of more advanced databinding methods, which automatically handle the aforementioned functions:
Declarative DataSource
Programmatic Data Binding
Also, you can temporarily remove the IgnorePaging and change the Format, because ExcelML has some specifics with Grouping:
