Martin is right here, you can not manipulate the report control in virtual mode.

Hi;

Whenever you delete records in virtual mode you have to perform it in the underlying (extern) data container (not part of the report control) then you have to call SetVirtualMode(new MyRecordType(...), NewNumberOfElements); followed by Populate();
I've never tried to manipulate the records collection of the report control directly in virtual mode since it makes no sense, but I believe thats absolutely wrong! The control only holds one dummy record and calls GetItemMetrics() whenever a row should be drawn.

Hello CJ Team,

Deleting selected record from the virtual mode should decrease record count. Please go through following sample code

int count =GetReportCtrl().GetRecords()->GetCount();

//eg. count is 100

//Selected 10 records and delete them. Expected count should be 90

CXTPReportSelectedRows* pSelectedRows = GetReportCtrl().GetSelectedRows();

if(!pSelectedRows)

return;

int nRow = pSelectedRows->GetCount() - 1;

if(nRow < 0)

return;

CWaitCursor wc;

CXTPReportRow* pFocusedRow = pSelectedRows->GetAt(pSelectedRows->GetCount() - 1);

pFocusedRow = GetRows()->GetAt(pFocusedRow->GetIndex() + 1);

while(nRow >= 0)

{

CXTPReportRecord* pRecord = pSelectedRows->GetAt(nRow--)->GetRecord();

if(pRecord)

GetReportCtrl().RemoveRecordEx(pRecord);

if(nRow >= pSelectedRows->GetCount())

nRow = pSelectedRows->GetCount() - 1;

}

GetReportCtrl().SetFocusedRow(pFocusedRow ? pFocusedRow : GetReportCtrl().GetFocusedRow());

count =GetReportCtrl().GetRecords()->GetCount();

//Actual count still 100

Problem when it comes in the GetItemMetrics(..) and trying to fetch the records which are already deleted (Records from 90 to 100).

Waiting for reply.
