This is cut off at the first for loop on our board, wonder whether we have a 'conflicting' hack:

internal void MoveRow_FromTo(int iRowSrc, int iRowDst)

{

if (this.tabTally.SelectedTab == this.tabBHA)

{

int iSeqNoSrc = (int)this.m_usctblBHAActivityAssetList.grd[iRowSrc, "SeqNo"];

int iSeqNoDst = (int)this.m_usctblBHAActivityAssetList.grd[iRowDst, "SeqNo"];



if (iRowSrc > iRowDst)

{

this.m_usctblBHAActivityAssetList.grd[iRowSrc, "SeqNo"] = iSeqNoDst;

int iSeQNo = (int)this.m_usctblBHAActivityAssetList.grd[iRowDst,"SeqNo"];

for (int i = iRowDst; i <= iRowSrc-1; i++)

{

iSeQNo = iSeQNo+1;

this.m_usctblBHAActivityAssetList.grd[i,"SeqNo"] = iSeQNo;

}



}

else if (iRowDst == this.m_usctblBHAActivityAssetList.grd.Rows.Count-1)

{

int iSeqNo = (int)this.m_usctblBHAActivityAssetList.grd[iRowSrc, "SeqNo"];

this.m_usctblBHAActivityAssetList.grd[iRowSrc, "SeqNo"] = iSeqNoDst;



for (int i = iRowSrc+1; i <= this.m_usctblBHAActivityAssetList.grd.Rows.Count-1; i++)

{

this.m_usctblBHAActivityAssetList.grd[i,"SeqNo"] = iSeqNo;

iSeqNo = iSeqNo+1;

}

}

else

{

int iSeqNo = (int)this.m_usctblBHAActivityAssetList.grd[iRowDst+1, "SeqNo"];

this.m_usctblBHAActivityAssetList.grd[iRowSrc, "SeqNo"] = iSeqNoDst+1;



for (int i = iRowDst+1; i <= this.m_usctblBHAActivityAssetList.grd.Rows.Count-1; i++)

{

iSeqNo = iSeqNo+1;

this.m_usctblBHAActivityAssetList.grd[i,"SeqNo"] = iSeqNo;

}

}

}

else if (this.tabTally.SelectedTab == this.tabDrillString)

{

int iSeqNoSrc = (int)this.m_usctblActivityAssetList.grd[iRowSrc, "SeqNo"];

int iSeqNoDst = (int)this.m_usctblActivityAssetList.grd[iRowDst, "SeqNo"];



if (iRowSrc > iRowDst)

{

this.m_usctblActivityAssetList.grd[iRowSrc, "SeqNo"] = iSeqNoDst;

int iSeQNo = (int)this.m_usctblActivityAssetList.grd[iRowDst,"SeqNo"];

for (int i = iRowDst; i <= iRowSrc-1; i++)

{

iSeQNo = iSeQNo+1;

this.m_usctblActivityAssetList.grd[i,"SeqNo"] = iSeQNo;

}



}

else if (iRowDst == this.m_usctblActivityAssetList.grd.Rows.Count -1)

{

int iSeqNo = (int)this.m_usctblActivityAssetList.grd[iRowSrc, "SeqNo"];

this.m_usctblActivityAssetList.grd[iRowSrc, "SeqNo"] = iSeqNoDst;



for (int i = iRowSrc+1; i <= this.m_usctblActivityAssetList.grd.Rows.Count-1; i++)

{

this.m_usctblActivityAssetList.grd[i,"SeqNo"] = iSeqNo;

iSeqNo = iSeqNo+1;

}

}

else

{

int iSeqNo = (int)this.m_usctblActivityAssetList.grd[iRowDst+1, "SeqNo"];

this.m_usctblActivityAssetList.grd[iRowSrc, "SeqNo"] = iSeqNoDst+1;

for (int i = iRowDst+1; i <= this.m_usctblActivityAssetList.grd.Rows.Count-1; i++)

{

iSeqNo = iSeqNo+1;

this.m_usctblActivityAssetList.grd[i,"SeqNo"] = iSeqNo;

}

}

}

}

<= is causing problems on our board.

I find statements like:
for (int i = iRowSrc+1; i <= this.m_usctblActivityAssetList.grd.Rows.Count-1; i++)

To be very suspicious. Are you sure that you aren't off by one there? Could you just compare i < Rows.Count rather than i<=Rows.Count-1 ?

All those plus ones and minus ones are trouble.
