 Topic: How to implement OnSelectionChanging?Posted: 28 June 2007 at 11:39am |

Hi;
does anyone know how to implement a OnSelectionChanging function into the report control to have an opportunity to cancel any outstanding changes to the currently focused row?
It would be fine if the control sends a XTP_NM_REPORT_SELECTIONCHANGING notification to the owner of the control before the new row gets selected. I looked into the report samples with no success.
So any hints on how to do it are very welcome...

Hi,
There is an XTP_NM_REPORT_SELCHANGED event fired. Remember currently focused row, which you don't want to change, and use CXTPReportControl::SetFocusedRow to return selection back. Also use some internal flag in XTP_NM_REPORT_SELCHANGED to avoid recurrent sending of XTP_NM_REPORT_SELCHANGED event. See SetFocusedRow implementation for more details. -- WBR, Serge |

Hi Serge,
you solution works, but it first sets the focus to the new row, resulting in a unwanted flickering of selections.
Any ideas how to prevent this?
