Multiple cell selection and context menu

[Mats]

Hi!

I have a grid with multiple cell selection enabled - CellSelectionMode="MultiCell".

It works great when I select multiple cells. But when I right click on one of the selected cells to bring up a context menu then all cells will be deselected except the on that I right click.

I want all selected cells to stay selected when I right click on a selected cell. Is it possible to cancel the deselecting in this case?

Thanks

Solved it by cancelling the 'OnCellSelecting' and 'OnCellDeselecting' events if the cell that is right clicked is already selected.
Added jscript and client settings for the grid.

function cellIsSelected(element) {
    if (element) {
        if (element.className.indexOf("rgSelectedCell") >= 0)
            return true;
        else
            return cellIsSelected(element.parentElement);
    }
    return false;
}

function rightButtonClicked(e) {
    if (!e) e = new Sys.UI.DomEvent(window.event);
    if ((e.type == 'mousedown') || (e.type == 'mouseup'))
        return e.button > 0;
    return false;
}

function cellSelecting(sender, args) {
    var e = new Sys.UI.DomEvent(window.event);
    if (rightButtonClicked(e) && cellIsSelected(e.target))
        args.set_cancel(true);
}

function cellDeselecting(sender, args) {
    var e = new Sys.UI.DomEvent(window.event);
    if (rightButtonClicked(e) && cellIsSelected(e.target))
        args.set_cancel(true);
}

// And setting the event handlers for the grid
        <ClientSettings >
            <ClientEvents OnCellSelecting="cellSelecting" OnCellDeselecting="cellDeselecting"  />
            <Selecting CellSelectionMode="MultiColumn"></Selecting>
        </ClientSettings>
