Kevin,

What happens is I have a lstRemainingLots_SelectedIndexChanged event where I call GetLotLineItems to repopulate the EntityList that the gvLots is bound to. As soon as I call the BO method that repopulates the EntityList, that's when the row_DataBound fires for the grid and I get the RowNotInTable error message.

protected void lstRemainingLots_SelectedIndexChanged(object sender, EventArgs e)
    {
        GetLotLineItems();
    }

private void GetLotLineItems()
{
if (!this.chkShowInactive.Checked)
{
//When LotLineItems.EntityList is repopulated
//gvLots_RowDataBound fires and RowNotInTable exception occurs
            LotLineItems.EntityList = LotLineItems.GetLotsByLidActive(Convert.ToInt32(lstRemainingLots.SelectedValue));
}
else
            LotLineItems.EntityList = LotLineItems.GetLotsByLid(Convert.ToInt32(lstRemainingLots.SelectedValue));

        Session["dsLots"] = LotLineItems.DataSet;
        this.BindControl(gvLots);
}
