Report Control Expand Button

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi, I have configured a cell in a report control to have an expand button, the only notification message I can see that might be for this is XTP_NM_REPORT_SHOWFIELDCHOOSER but when the button is clicked this notification message is not sent.  After a quick search of the source code it appears that this message is never sent, am I missing something or is there some other way to know when the button is clicked? 
Also I would like to be able to choose multiple items from a dialog by clicking the expand button and then show a summary in the grid cell, but I don't want the user to be able to edit the summary shown in the cell directly.  Is this possible, if you make the cell non-editable then you can't see the expand button?
Thanks.

	Never mind, I've worked it out. It sends the same notification message as the combo button, XTP_NM_REPORT_INPLACEBUTTONDOWN. And I can stop the text being edited by setting the cell to be a constrained edit and then setting my summary string as the one and only constraint, again like the combo box, i.e. GetEditOptions(NULL)->m_bConstraintEdit = TRUE; GetEditOptions(NULL)->AddConstraint( strSummary ); This means the cell can be editable so the button is active but the text cant be changed directly - as required.
