Problem

 


I want to be able to attach a recordset to a bound grid after calling OnInitialUpdate() and start with an empty grid? Is this possible?

 

 


Cause

 


 

 


Action

 


Yes. Simply don't call SetRecordset(pRecordset) before calling OnInitialUpdate(). If the grid has no pointer to a recordset, it will not try to open the set.

Later, when you want to attach a recordset, you should call SetRecordset() and OpenRecordset().

Example:
 

void CMyGrid::OnAttachRecordset()
{
m_pSet = new CRecordset;
SetRecordset(m_pSet);
__super::OpenRecordset();
}
