I'm sure there is an easy answer to this and I've simply missed it in my searching on the forum and in the code... I'm using a CXTPReportControl with multiple columns. By default it sorts the first column alphabetically when I call Populate. How can I disable sorting so that the records are listed in the order that I added them? I've tried setting all columns->SetSortable( FALSE ); prior to calling Populate but that did not work. Thanks in advance. |

The control sorts records by 2 collections: GroupsOrder and SortOrder. If both of them contain zero elements, the sorting wouldn't be called.
So, please check elements count in CXTPReportColumns::GetGroupsOrder() and CXTPReportColumns::GetSortOrder() collections. -- WBR, Serge |

Thank you sserge for the reply. I was able to call Clear for both CXTPReportColumns::GetGroupsOrder() and CXTPReportColumns::GetSortOrder() and then confirmed both were empty by using GetCount just before calling Populate. Unfortunately after calling Populate the Report Control is still sorted (no change) alphabetically by the first column. [UPDATE] Your solution was correct. I had recently switched my storage of the items to be put into the report from a std::vector to a std::map.
Thank you. |
I forgot a map automatically sorts the keys by its very nature, so iterating through the map was giving me a sorted list and not the order I generated the list of records in.
