    int groupRowHandle
)

Remarks

The GetChildRowCount(Int32) method allows you to obtain the number of data rows within a specific group. This method accepts a group row handle as a parameter. Group row handles are integer numbers in reverse order starting with -1.

Note

Do not confuse handles for data and group rows. Data row handles are integer numbers in direct order starting with zero.

The GetChildRowHandle(Int32, Int32) method allows you to obtain a data row handle. Pass the group row handle as the first parameter and the zero-based index of the data row in this group as the second parameter.

If the specified group row handle does not exist or the specified group does not contain a data row at the specified position, the GetChildRowHandle(Int32, Int32) method returns the InvalidRowHandle property value.
