Kevin,

After reading your source code, it in fact does matter, the PK can't be anything but an INT for the mover control to work, even if the db has a smallint it doesn't work. I have confirmed this with others around here.

It's under the "MoveItem" function of the mmmovercontrol

protected virtual void MoveItem()
{
if (AvailablePK is int)
{
...
}
}

Above is the extracted code, that's why it doesn't work.

Thanks for your help, Took forever to figure out what was wrong.
