No problem, firstly look at help files to see the difference between Record and a Row.

Iterating difference is in their order. If you iterate Records, you'll take them in the order like you were adding them into the control. If you iterate Rows, they go in order like they're displayed.

Here is the example (add there NULL checks, etc):


CXTPReportRows* pRows = wndReport.GetRows();
for(int j = 0; j < pRows->GetCount(); j++)
{
    CXTPReportRow* pRow = pRows->GetAt(j);
    CXTPReportRecord* pRecord = pRow->GetRecord();
    
    for (int i = 0; i < pRecord->GetItemCount(); i++)
    {
        CXTPReportRecordItem* pItem = pRecord->GetItem(i);
        if (pItem)
        {
            ASSERT(pItem->GetCaption(NULL).IsEmpty());
        }
    }        
}

thanx sserge,

this does what i want (after some minor modifications).

could you elaborate (maybe provide an example) on what you mean by iterating ReportRows?

thnx

iterating items : Your code above has an error....

Your code above has an error. GetRecords() returns a collection of records, not just a single one. So far, to iterate all records and then items it would be:


    CXTPReportRecords* pRecords = wndReport.GetRecords();
    CXTPReportRecord* pRecord = NULL;

    int nRecordCnt = pRecords->GetCount();
    for(int i = 0; i < nRecordCnt; i++)
    {
        pRecord = pRecords->GetAt(i);
        
        // there goes my previous piece of code
        CXTPReportRecordItem* pItem = NULL;
        for (int j = 0; j < pRecord->GetItemCount(); j++)
        {
            pItem = pRecord->GetItem(j);
            if (pItem)
            {
                ASSERT(pItem->GetCaption(NULL).IsEmpty());
            }
        }        
    }

ps: by your description, you probably need to iterate ReportRows, and only then take and check a Record from a Row.

Sserge, thanx for your reply. However it doesn't seem to do what I want. Here is the code:

    CXTPReportRecordItem* pItem = NULL;
   CXTPReportRecord* pRecord = (CXTPReportRecord*)m_wndReport.GetRecords();

    int nItemCnt = pRecord->GetItemCount();

    for(int i = 0; i < nItemCnt; i++)
    {
        pItem = pRecord->GetItem(i);
        if(pItem)   // IT NEVER GETS INSIDE HERE
        {
            ASSERT(pItem->GetCaption(NULL).IsEmpty());
        }
    }

it never gets inside the if(pItem) statement.

am i missing something?

Basically this is what I want to do: when the user clicks on a button,i want to get a total count of all the rows in the report. thenstarting with the first row, i want to iterate thru all the items &find out if there are any empty items. if so, i want to break out ofthe look & set focus (maybe change the cell color) to the firstempty item.

Hi,

If you have a record pointer, you can iterate it in a very simple manner:


CXTPReportRecordItem* pItem = NULL;
for (int i = 0; i < pRecord->GetItemCount(); i++)
{
    pItem = pRecord->GetItem(i);
    if (pItem)
    {
        ASSERT(pItem->GetCaption(NULL).IsEmpty());
    }
}

i am looking for a good example (vc++) on how to iterate through every single item(column) on a record (row).

i can get the row, but i want to scan every item & find out which item is empty (" ").

Thanx in advance
