Hi Joel,
One way you can do this by adding your own custom Categorizer object to the SortColumnDescriptor. Once the column is grouped, the custom Categorizer is used to determine which adjacent records in the column belong to the same group. To create custom Categorizer objects, you define classes that implement ICategorizer (two methods). Please refer to the atttached sample and let me know if this helps.
private void GroupedColumns_Changed(object sender, Syncfusion.Collections.ListPropertyChangedEventArgs e)
{
if( e.Action == Syncfusion.Collections.ListPropertyChangedType.Insert)
{
SortColumnDescriptor column = e.Item as SortColumnDescriptor;
if( column.Name == "DateTime")
column.Categorizer = new CustomCategorizer();
}
}
