Dear Support,

I need to move a row in a grid up or down when a user clicks on a button.
How can this be done?

Thanks,
Ron.

There is a SwapDroppedSeries method in the CExtGridDataProvider class which moves the column or row to a new position and returns true if succeeded.

CExtGridDataProvider & _DataProvider = m_wndGrid.OnGridQueryDataProvider();
VERIFY(
	_DataProvider.SwapDroppedSeries(
		false,
		nRowColNoSrc,
		nRowColNoDropBefore,
		&m_wndGrid
		)
	);

Dear Support,

I am trying to move the selected row down, this is what I wrote:

CPoint pt = FocusGet();
CExtGridDataProvider& dataProvider = OnGridQueryDataProvider();
dataProvider.SwapDroppedSeries(false, pt.y, pt.y+1, this);
OnSwDoRedraw();

And nothing happened. What am I don’t wrong? What are the value I need to pass at the nRowColNoSrc and nRowColNoDropBefore?

Thanks,
Ron.

Let’s assume Yg is a zero-based row number in the grid control which has Yt header rows at the top and Yb header rows at the bottom. Then the data provider index should be as follows:

Ydp = Yt + Yb + Yg
