Hello,

One complication is that some of the columns can be changed dynamically by the user, depending on which column is currenty visible, Column5 could then become sum of col1 + col4 for e.g.

I could not do this in the OnEditChanged() of the CXTPReportRecordItem because I was unable to determine how to find out if the record item was visible or not.

I manually update everything in the ON_NOTIFY(XTP_NM_REPORT_VALUECHANGED, IDC_BEFORE_CNCTN, OnBeforeCnctnValueChanged) function. Code is attached.

Here is the problem. Let's say currenty I have visble col 0, 1, 2, 3, and 5. Col5 is sum of col1 & 3. If I change col1, col5 gets updated correctly.
However, if I now change col5, col1 is supposed to automatically update as difference of col5 and 3. But I am unable to update col5 once I enter values in col1, and col5 updates automatically.

 

Code is copied here: The .h and .cpp files are attached.
