试试:

int rowIndex = Convert.ToInt32(e.CommandArgument) % GridView1.PageSize;

您可以尝试使用CommandSource。

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    var control = e.CommandSource as Control;
    var gridViewRow = control.NamingContainer as GridViewRow;
    int rowIndex = gridViewRow.RowIndex;
    ....
}
