Scrolling with the mouse wheel

[Fady Sayegh]

Hi to all,

i have 2 GridControl, when i scroll in the first i need to do the same with the second.
i made this with the event "VerticalScroll". However when i scroll the GridControl with the mouse wheel the "VerticalScroll" event does not fire and my second GridControl does not scroll.


here the code to scroll when the user click in the vertical scroll bar

if (e.Type == ScrollEventType.EndScroll)
{
// scroll the second grid control
gdc2.ScrollCellInView(gdc2.RowCount, 2);
gdc2.ScrollCellInView(e.NewValue, 2);
}


does anyone has some ideas

Best regards and thanks in advance

Hi Fady,

We appreciate your kindly patience. This can be achieved by handling the TopRowChanged event and changing the TopRowIndex property of grid 2. Please refer to the following code snippet for details.

>>>>>>>>>>>>>>>><<<<<<<<<<<<
void gridControl1_TopRowChanged(object sender, GridRowColIndexChangedEventArgs e)
{
Synchronize_TopRowChanged(gridControl2, gridControl1, e);
}

void Synchronize_TopRowChanged(GridControl targetGrid, GridControl sourceGrid, GridRowColIndexChangedEventArgs e)
{
if (inTopRowChangedEvent)
return;

inTopRowChangedEvent = true;
try
{
targetGrid.TopRowIndex = sourceGrid.TopRowIndex;
}
finally
{
inTopRowChangedEvent = false;
}
}

Please refer to the following KB article for more details

Have a nice time.
