(un)checking all rows of the selection

Need non-item related function (Control level) - SetSelectionState(int state) where state can be 0, 1 or 2 (tristate checkbox). But if row / record have more than one checkboxes? So need smth like SetSelectionState(int index, int state). And you need to have menu (fixed or context) or button for UI to call this function and different buttons for several checkboxes in row

Finally I implemented both flags and you can try to play with this feature in static sample

 

There are couple of columns with checkboxes in the right part - scroll if not see it. Both flags set ON in this app so your action will extend for all selection

Using the right-click to set the selection is not an option because our users are used to using the left button-click.

I however managed to get it working in the same way like Visual Studio 2008 Pending Changes with the current CodeJock version (13.0).

I have set AutoCheckItems to FALSE because I only want the check-box to be checked when the user clicks on the check box and not on the other part of the record item.

In the OnLButtonUp of my CXTPReportControl class I check if the clicked row = m_pSelectOnUpRow. If this is true and the user clicked on the check box area (I am using a helper function on my implementation of CXTPReportRecordItem), the m_pSelectOnUpRow is set to NULL and the focus is set to the clicked row (with bIgnoreSelection = TRUE).

The XTP_NM_REPORT_CHECKED message is handled by my CXTPReportControl class and sets the check state of all selected rows to the inversed value of the clicked row (only when the click is on the check box area).

The function SetSelectionState can be handy but does not complete the whole job. A function on CXTPReportRecordItem or CXTPReportRow to check if a point is in the check box area of the row/item would also be very usefull (e.g. HitCheckboxTest).
