#Returns
Type | Description |
---|---|
Int32 | An integer value representing the number of the specified group row’s immediate children. 0 if the specified row is a data row. |
#Remarks
When rows are grouped by multiple columns, group and data rows form a hierarchy. Root group rows correspond to the first column within the ColumnView.GroupedColumns collection. If passing handles of such rows to the GetChildRowCount method, the return value will indicate the number of second level group rows that are owned by the specified root row. Note that data rows are children of group rows that correspond to the last column within the ColumnView.GroupedColumns collection. Passing handles of such group rows will result in obtaining the number of data rows that belong to the specified group.
The GetChildRowCount method can be used in combination with the GridView.GetChildRowHandle method to traverse through the group rows hierarchy.
