Help!
I want to delete a row from a TStringGrid. I tried
((TCustomGrid*)MyStringGrid)->DeleteRow(SelRow); where SelRow is an int.
It tells me that DeleteRow is not accessible.
Thanks for help

not provide public access to it. In order to access DeleteRow(), you need
to derive a new class and provide your own access to it, ie:
class TMyStringGrid : public TStringGrid
{
public:
__fastcall TMyStringGrid(TComponent *Owner)
: TStringGrid(Owner)
{
}
void __fastcall DeleteARow(int ARow)
{
TCustomGrid::DeleteRow(ARow);
}
};
Otherwise, you will just have to forget using the grid's DeleteRow() and
just manipulate the rows manually, ie
void __fastcall TForm1::DeleteRow(int Row)
{
if( Row>= StringGrid1->FixedRows )
{
// move the content below the desired row up a row
for(int x = Row; x < (StringGrid1->RowCount-1); ++x)
StringGrid1->Rows[x]->Assign(StringGrid1->Rows[x+1]);
// resize the grid to remove or clear the last row.
// note - the grid does not support having 0 non-fixed rows
if( StringGrid1->RowCount>(StringGrid1->FixedRows+1) )
StringGrid1->RowCount = (StringGrid1->RowCount - 1);
else
StringGrid1->Rows[StringGrid1->FixedRows]->Clear();
}
}

Thank you - works like a charm!

TCustumGrid ::DeleteColumn()) alter the contents of the remaing row and
columns, creating a mess with the data stored in the StringGrid's cells.

I wrote an article on an advance String Grid that supports both Col/Row
delete
and Col/Row insert operations as well as SaveFile and ReadFile operations
