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.

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?
