Hi,

In my control the users can rightclick the column header and select remove column.
Lets say there were three columns with nItemIndex 0,1,2
The user removes the rightmost column.
After the column has been removed, the indexes are 0,1.

Then the user can add a new column.
Now the indexes are 0,1,3

When the rows are drawn in CXTPReportRow::Draw, the item is located:
CXTPReportRecordItem* pItem = m_pRecord->GetItem(pColumn);

Inside GetItem:

CXTPReportRecordItem* CXTPReportRecord::GetItem(CXTPReportColumn* pColumn)
{
if (this == NULL)
return NULL;
int nItemIndex = pColumn->GetItemIndex();
if (nItemIndex >= 0 && nItemIndex < GetItemCount())
{
return m_arrItems.GetAt(nItemIndex);
}
return NULL;
}

Seems you have bug in your code. There can't be situation with 0,1,3 indexes.

If  user remove column, m_bVisible of  CXTPReportColumn must be set as FALSE. it doen't remove from array of columns.

Please attach what additional code you added for Remove operation.

When i remove a column, i do:

CXTPReportColumns* pColumns = m_cGrid.GetColumns();
...Code to locate the correct column
pColumns->Remove(pColumn);

In CXTPReportColumns::Remove, the column is just removed from the array, the other columns indexes are not adjusted, so after remove, I can see in the debugger Watch window that
pColumns->m_arrColumns.m_pData[0].m_nItemIndex == 0
pColumns->m_arrColumns.m_pData[1].m_nItemIndex == 1
pColumns->m_arrColumns.m_pData[2].m_nItemIndex == 3
